12.1 Mechanism of Action The mechanism of action of olanzapine and fluoxetine in the listed indications, is unclear. However, the combined effect of olanzapine and fluoxetine at the monoaminergic neural systems (serotonin, norepinephrine, and dopamine) could be responsible for the pharmacological effect.

الجرعة وطريقة الإعطاء

2 DOSAGE AND ADMINISTRATION Adult Starting Dose: 6 mg olanzapine with 25 mg fluoxetine (6 mg/25 mg, once daily in the evening ( 2.1 , 2.2 ) Adult Maximum Dose: 12 mg/50 mg once daily ( 2.1 , 2.2 ) Pediatric Bipolar Depression Starting Dose: 3 mg/25 mg once daily (for ages 10 to 17 years) ( 2.1 ) Pediatric Bipolar Depression Maximum Dose: 12 mg/50 mg ( 2.1 ) Starting dose in patients predisposed to hypotensive reactions, hepatic impairment, or with potential for slowed metabolism: 3 mg/25 mg to 6 mg/25 mg. Escalate dose cautiously ( 2.3 ) 2.1 Depressive Episodes Associated with Bipolar I Disorder Adults – Administer Olanzapine and Fluoxetine Capsules once daily in the evening, generally beginning with the 6 mg/25 mg (mg olanzapine/mg equivalent fluoxetine) capsule. While food has no appreciable effect on the absorption of olanzapine and fluoxetine given individually, the effect of food on the absorption of olanzapine and fluoxetine has not been studied. Make dosage adjustments, if indicated, according to efficacy and tolerability. Antidepressant efficacy was demonstrated with olanzapine and fluoxetine in a dose range of olanzapine 6 mg to 12 mg and fluoxetine 25 mg to 50 mg [see Clinical Studies (14.1)] . The safety of doses above 18 mg of olanzapine and 75 mg of fluoxetine has not been evaluated in adult clinical studies. Periodically reexamine the need for continued pharmacotherapy. Children and Adolescents (10 to 17 years of age) – Administer Olanzapine and Fluoxetine Capsules once daily in the evening, generally beginning with the 3 mg/25 mg capsule, without regard to meals, with a recommended target dose within the approved dosing range (6/25; 6/50; 12/25; 12/50 mg) [see Clinical Studies (14.1)] . The safety of doses above 12 mg of olanzapine and 50 mg of fluoxetine has not been evaluated in pediatric clinical studies. Periodically reexamine the need for continued pharmacotherapy. 2.2 Treatment Resistant Depression Administer Olanzapine and Fluoxetine Capsules once daily in the evening, generally beginning with the 6 mg/25 mg capsule. While food has no appreciable effect on the absorption of olanzapine and fluoxetine given individually, the effect of food on the absorption of Olanzapine and Fluoxetine Capsules has not been studied. Adjust dosage, if indicated, according to efficacy and tolerability. Antidepressant efficacy was demonstrated with Olanzapine and Fluoxetine Capsules in a dose range of olanzapine 6 mg to 18 mg and fluoxetine 25 mg to 50 mg [see Clinical Studies (14.2)] . The safety of doses above 18 mg/75 mg has not been evaluated in clinical studies. Periodically reexamine the need for continued pharmacotherapy. 2.3 Specific Populations Start Olanzapine and Fluoxetine Capsules at 3 mg/25 mg or 6 mg/25 mg in patients with a predisposition to hypotensive reactions, patients with hepatic impairment, or patients who exhibit a combination of factors that may slow the metabolism of olanzapine and fluoxetine (female gender, geriatric age, nonsmoking status) or those patients who may be pharmacodynamically sensitive to olanzapine. Titrate slowly and adjust dosage as needed in patients who exhibit a combination of factors that may slow metabolism. Olanzapine and Fluoxetine has not been systematically studied in patients >65 years of age or in patients <10 years of age [see Use in Specific Populations (8.5) and Clinical Pharmacology (12.3, 12.4)] . 2.4 Switching a Patient To or From a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with olanzapine and fluoxetine. Conversely, at least 5 weeks should be allowed after stopping olanzapine and fluoxetine before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4.1)] . 2.5 Use of Olanzapine and Fluoxetine Capsules with Other MAOIs such as Linezolid or Methylene Blue Do not start olanzapine and fluoxetine in a patient who is being treated with linezolid or intravenous methylene blue because there is an increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization, should be considered [see Contraindications (4.1)] . In some cases, a patient already receiving olanzapine and fluoxetine therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue are judged to outweigh the risks of serotonin syndrome in a particular patient, olanzapine and fluoxetine should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for five weeks or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with olanzapine and fluoxetine may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions (5.6)] . The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with olanzapine and fluoxetine is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use [see Warnings and Precautions (5.6)]. 2.6 Discontinuation of Treatment with Olanzapine and Fluoxetine Capsules Symptoms associated with discontinuation of fluoxetine, a component of olanzapine and fluoxetine, SNRIs, and SSRIs, have been reported [see Warnings and Precautions (5.25)] .

The data in the tables represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse reaction of the type listed. A reaction was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. Adults — The information below is derived from a clinical study database for olanzapine and fluoxetine consisting of 2547 patients with treatment resistant depression, depressive episodes associated with Bipolar I Disorder, Major Depressive Disorder with psychosis, or sexual dysfunction with approximately 1085 patient-years of exposure. The conditions and duration of treatment with olanzapine and fluoxetine varied greatly and included (in overlapping categories) open-label and double-blind phases of studies, inpatients and outpatients, fixed-dose and dose-titration studies, and short-term or long-term exposure. Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Controlled Studies Including Depressive Episodes Associated with Bipolar I Disorder and Treatment Resistant Depression - Overall, 11.3% of the 771 patients in the olanzapine and fluoxetine group discontinued due to adverse reactions compared with 4.4% of the 477 patients for placebo. Adverse reactions leading to discontinuation associated with the use of olanzapine and fluoxetine (incidence of at least 1% for olanzapine and fluoxetine and greater than that for placebo) using MedDRA Dictionary coding were weight increased (2%) and sedation (1%) versus placebo patients which had 0% incidence of weight increased and sedation. Commonly Observed Adverse Reactions in Controlled Studies Including Depressive Episodes Associated with Bipolar I Disorder and Treatment Resistant Depression - In short-term studies, the most commonly observed adverse reactions associated with the use of olanzapine and fluoxetine (incidence ≥5% and at least twice that for placebo in the olanzapine and fluoxetine-controlled database) using MedDRA Dictionary coding were: disturbance in attention, dry mouth, fatigue, hypersomnia, increased appetite, peripheral edema, sedation, somnolence, tremor, vision blurred, and weight increased. Adverse reactions reported in clinical trials of olanzapine and fluoxetine in combination are generally consistent with treatment-emergent adverse reactions during olanzapine or fluoxetine monotherapy. In a 47-week maintenance study in adults with treatment resistant depression, adverse reactions associated with olanzapine and fluoxetine use were generally similar to those seen in short-term studies. Weight gain, hyperlipidemia, and hyperglycemia were observed in olanzapine and fluoxetine-treated patients throughout the study. Adverse Reactions Occurring at an Incidence of 2% or More in Short-Term Controlled Studies Including Depressive Episodes Associated with Bipolar I Disorder and Treatment Resistant Depression — Table 16 enumerates the treatment-emergent adverse reactions associated with the use of olanzapine and fluoxetine (incidence of at least 2% for olanzapine and fluoxetine and twice or more than for placebo). The olanzapine and fluoxetine-controlled column includes patients with various diagnoses while the placebo column includes only patients with bipolar depression and major depression with psychotic features. Table 16: Adverse Reactions: Incidence in the Short-Term Controlled Clinical Studies in Adults System Organ Class Adverse Reaction Percentage of Patients Reporting Event Olanzapine and Fluoxetine-Controlled (N=771) Placebo (N=477) Eye disorders Vision blurred 5 2 Gastrointestinal disorders Dry mouth 15 6 Flatulence 3 1 Abdominal distension 2 0 General disorders and administration site conditions Fatigue 12 2 Edema a 15 2 Asthenia 3 1 Pain 2 1 Pyrexia 2 1 Infections and infestations Sinusitis 2 1 Investigations Weight increased 25 3 Metabolism and nutrition disorders Increased appetite 20 4 Musculoskeletal and connective tissue disorders Arthralgia 4 1 Pain in extremity 3 1 Musculoskeletal stiffness 2 1 Nervous system disorders Somnolence b 27 11 Tremor 9 3 Disturbance in attention 5 1 Psychiatric disorders Restlessness 4 1 Thinking abnormal 2 1 Nervousness 2 1 Reproductive system and breast disorders Erectile dysfunction 2 1 a Includes edema, edema peripheral, pitting edema, generalized edema, eyelid edema, face edema, gravitational edema, localized edema, periorbital edema, swelling, joint swelling, swelling face, and eye swelling. b Includes somnolence, sedation, hypersomnia, and lethargy. Extrapyramidal Symptoms Dystonia, Class Effect for Antipsychotics — Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, the frequency and severity are greater with high potency and at higher doses of first generation antipsychotic drugs. In general, an elevated risk of acute dystonia may be observed in males and younger age groups receiving antipsychotics; however, events of dystonia have been reported infrequently (<1%) with the olanzapine and fluoxetine combination. Additional Findings Observed in Clinical Studies Sexual Dysfunction — In the pool of controlled olanzapine and fluoxetine studies in patients with bipolar depression, there were higher rates of the treatment-emergent adverse reactions decreased libido, anorgasmia, erectile dysfunction and abnormal ejaculation in the olanzapine and fluoxetine group than in the placebo group. One case of decreased libido led to discontinuation in the olanzapine and fluoxetine group. In the controlled studies that contained a fluoxetine arm, the rates of decreased libido and abnormal ejaculation in the olanzapine and fluoxetine group were less than the rates in the fluoxetine group. None of the differences were statistically significant. Sexual dysfunction, including priapism, has been reported with all SSRIs. While it is difficult to know the precise risk of sexual dysfunction associated with the use of SSRIs, healthcare providers should routinely inquire about such possible side effects. There are no adequate and well-controlled studies examining sexual dysfunction with olanzapine and fluoxetine or fluoxetine treatment. Symptoms of sexual dysfunction occasionally persist after discontinuation of fluoxetine treatment. Difference Among Dose Levels Observed in Other Olanzapine Clinical Trials In a single 8-week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200), and 40 (N=200) mg/day of olanzapine in patients with Schizophrenia or Schizoaffective Disorder, statistically significant differences among 3 dose groups were observed for the following safety outcomes: weight gain, prolactin elevation, fatigue, and dizziness. Mean baseline to endpoint increase in weight (10 mg/day: 1.9 kg; 20 mg/day: 2.3 kg; 40 mg/day: 3 kg) was observed with significant differences between 10 vs 40 mg/day. Incidence of treatment-emergent prolactin elevation >24.2 ng/mL (female) or >18.77 ng/mL (male) at any time during the trial (10 mg/day: 31.2%; 20 mg/day: 42.7%; 40 mg/day: 61.1%) with significant differences between 10 vs 40 mg/day and 20 vs 40 mg/day; fatigue (10 mg/day: 1.5%; 20 mg/day: 2.1%; 40 mg/day: 6.6%) with significant differences between 10 vs 40 and 20 vs 40 mg/day; and dizziness (10 mg/day: 2.6%; 20 mg/day: 1.6%; 40 mg/day: 6.6%) with significant differences between 20 vs 40 mg, was observed. Other Adverse Reactions Observed in Clinical Studies Following is a list of treatment-emergent adverse reactions reported by patients treated with olanzapine and fluoxetine in clinical trials. This listing is not intended to include reactions (1) already listed in previous tables or elsewhere in labeling, (2) for which a drug cause was remote, (3) which were so general as to be uninformative, (4) which were not considered to have significant clinical implications, or (5) which occurred at a rate equal to or less than placebo. Reactions are classified by body system using the following definitions: frequent adverse reactions are those occurring in at least 1/100 patients; infrequent adverse reactions are those occurring in 1/100 to 1/1000 patients; and rare reactions are those occurring in fewer than 1/1000 patients. Body as a Whole — Frequent: chills, neck rigidity, photosensitivity reaction; Rare: death 1 . Cardiovascular System — Frequent: vasodilatation. Digestive System — Frequent: diarrhea; Infrequent: gastritis, gastroenteritis, nausea and vomiting, peptic ulcer; Rare: gastrointestinal hemorrhage, intestinal obstruction, liver fatty deposit, pancreatitis. Hemic and Lymphatic System — Frequent: ecchymosis; Infrequent: anemia, thrombocytopenia; Rare: leukopenia, purpura. Metabolic and Nutritional — Frequent: generalized edema, weight loss; Rare: bilirubinemia, creatinine increased, gout. Musculoskeletal System — Rare: osteoporosis.

It is included here because of its seriousness. 2 Adjusted for gender. Other Adverse Reactions Observed with Olanzapine or Fluoxetine Monotherapy The following adverse reactions were not observed in olanzapine and fluoxetine-treated patients during premarketing clinical studies but have been reported with olanzapine or fluoxetine monotherapy: Bruxism, dysuria, esophageal ulcer, gynecological bleeding, headache, hypotension, neutropenia, sudden unexpected death 3 and sweating. 3 These terms represent serious adverse events but do not meet the definition for adverse drug reactions. They are included here because of their seriousness. Children and Adolescent Patients (aged 10 to 17 years) with a Diagnosis of Bipolar Depression The information below is derived from a single, 8-week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine for the treatment of bipolar I depression in patients 10 to 17 years of age. Adverse Reactions Associated with Discontinuation of Treatment in the single pediatric study — Overall, 14.1% of the 170 patients in the olanzapine and fluoxetine group discontinued due to adverse reactions compared with 5.9% of the 85 patients for placebo. Adverse reactions leading to discontinuation associated with the use of olanzapine and fluoxetine (incidence of at least 1% for olanzapine and fluoxetine and greater than that for placebo) using MedDRA Dictionary coding were weight increased (2.9%), suicidal ideation (1.8%), bipolar disorder (1.2%), and somnolence (1.2%) versus placebo patients which had 0% incidence of weight increased, bipolar disorder, and somnolence, and a 1.2% incidence of suicidal ideation. Adverse Reactions Occurring at an Incidence of 2% or more and greater than placebo — Table 17 enumerates the treatment-emergent adverse reactions associated with the use of olanzapine and fluoxetine (incidence of at least 2% for olanzapine and fluoxetine and twice or more than for placebo). Table 17: Treatment-Emergent Adverse Reactions: Incidence in a 8-week randomized, double-blind, placebo-controlled clinical trial in pediatric bipolar I depression System Organ Class Adverse Reaction Percentage of Patients Reporting Event Olanzapine and Fluoxetine (N=170) Placebo (N=85) Nervous system disorders Somnolence a 24 2 Tremor 9 1 Investigations Weight increased 20 1 Blood triglycerides increased 7 2 Blood cholesterol increased 4 0 Hepatic enzyme increased b 9 1 Gastrointestinal disorders Dyspepsia 3 1 Metabolism and nutrition disorders Increased appetite 17 1 Psychiatric disorders Anxiety 3 1 Restlessness 3 1 Suicidal ideation 2 1 Musculoskeletal and connective tissue disorders Back pain 2 1 Injury, poisoning and procedural complications Accidental overdose 3 1 Reproductive system and breast disorders Dysmenorrhea 2 0 a Includes somnolence, sedation, and hypersomnia. No lethargy was reported. b Includes alanine aminotransferase increased, aspartate aminotransferase increased, hepatic enzyme increased, liver function test abnormal, gamma-glutamyltransferase increased, and transaminases increased. Vital Signs and Laboratory Studies Adults: Vital Signs — Tachycardia, bradycardia, and orthostatic hypotension have occurred in olanzapine and fluoxetine-treated patients [see Warnings and Precautions (5.11)] . The mean standing pulse rate of olanzapine and fluoxetine-treated patients was reduced by 0.7 beats/min. Laboratory Changes — In olanzapine and fluoxetine clinical studies (including treatment resistant depression, depressive episodes associated with Bipolar I Disorder, Major Depressive Disorder with psychosis, or sexual dysfunction), olanzapine and fluoxetine was associated with statistically significantly greater frequencies for the following treatment-emergent findings in laboratory analytes (normal at baseline to abnormal at any time during the trial) compared to placebo: elevated prolactin (28% vs 5%); elevated urea nitrogen (3% vs 0.8%); elevated uric acid (3% vs 0.5%); low albumin (3% vs 0.3%); low bicarbonate (14% vs 9%); low hemoglobin (3% vs 0%); low inorganic phosphorus (2% vs 0.3%); low lymphocytes (2% vs 0%); and low total bilirubin (15% vs 4%). As with olanzapine, asymptomatic elevations of hepatic aminotransferases [ALT, AST, and GGT] and alkaline phosphatase have been observed with olanzapine and fluoxetine. In the olanzapine and fluoxetine-controlled database, clinically significant ALT elevations (change from <3 times the upper limit of normal [ULN] at baseline to ≥3 times ULN) were observed in 5% (38/698) of patients exposed to olanzapine and fluoxetine compared with 0.5% (2/378) of placebo-treated patients and 4% (33/751) of olanzapine-treated patients. ALT elevations ≥5 times ULN were observed in 2% (11/701) of olanzapine and fluoxetine-treated patients, compared to 0.3% (1/379) of placebo-treated patients and 1% (11/760) of olanzapine-treated patients. No patient with elevated ALT values experienced jaundice or liver failure, or met the criteria for Hy’s Rule. ALT values returned to normal, or were decreasing, at last follow-up in the majority of patients who either continued treatment with olanzapine and fluoxetine or discontinued olanzapine and fluoxetine. Rare postmarketing reports of hepatitis have been received in patients treated with olanzapine. Very rare cases of cholestatic or mixed liver injury have also been reported in the postmarketing period in patients treated with olanzapine. Caution should be exercised in patients with signs and symptoms of hepatic impairment, in patients with pre-existing conditions associated with limited hepatic functional reserve, and in patients who are being treated with potentially hepatotoxic drugs. An increase in creatine phosphokinase has been reported very rarely in olanzapine and fluoxetine-treated patients and infrequently in clinical trials of olanzapine-treated patients. QT Interval Prolongation — In patients treated with olanzapine and fluoxetine QT c F≥450 msec for males and QT c F≥470 msec for females has been reported frequently (≥1%). The incidence of QT c F>500 msec associated with olanzapine and fluoxetine treatment in clinical trials has been rare and was not significantly different from the incidence associated with placebo. The mean increase in QT c interval for olanzapine and fluoxetine-treated patients (5.17 msec) in the one clinical study directly comparing olanzapine and fluoxetine to placebo in adult patients was significantly greater than that for placebo-treated patients (-1.66 msec). Children and Adolescents (aged 10 to 17 years): In a single 8-week randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine for treatment of bipolar I depression in patients 10 to 17 years of age, the following was observed: Vital Signs — In the olanzapine and fluoxetine-treated patients compared with placebo-treated patients, the mean orthostatic blood pressure and standing pulse rate were not significantly different between treatment groups. Body Weight: An increase in weight greater than or equal to 7% occurred in 52.4% of the olanzapine and fluoxetine group and 3.6% of the placebo group. Weight gain greater than or equal to 15% occurred in 14.1% of the olanzapine and fluoxetine group and none of the placebo group. Laboratory Changes — Olanzapine and Fluoxetine was associated with statistically significantly greater frequencies for the following treatment-emergent findings in laboratory analytes (normal or low at baseline to abnormal at any time during the trial) compared to placebo: elevated ALT (45.9% vs 2.5%); elevated AST (33.7% vs 7.6%); high fasting total cholesterol (28.9% vs 8.2%); high fasting LDL cholesterol (19.7% vs 6.5%); high fasting triglycerides (52.3% vs 27.3%), and elevated prolactin (85% vs 36%). No patient with elevated hepatic enzyme values experienced jaundice or liver failure, or met the criteria for Hy’s Rule. Five patients experienced an adverse event potentially associated with elevated prolactin; these events included dysmenorrhea, galactorrhea, and ovulation disorder. QT Interval Prolongation — Olanzapine and Fluoxetine was associated with a statistically significantly greater mean increase in QT c F interval (8.2 msec [95% CI 6.2, 10.2]) compared with placebo. No patients developed QT c increases ≥60 msec or QT c ≥480 msec [see Warnings and Precautions (5.20)]. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of olanzapine and fluoxetine capsules, Fluoxetine, or Olanzapine monotherapy. Because these reactions are reported voluntarily from a population of uncertain size, it is difficult to reliably estimate their frequency or evaluate a causal relationship to drug exposure. Adverse reactions reported since market introduction that were temporally (but not necessarily causally) related to olanzapine and fluoxetine, fluoxetine, or olanzapine therapy include the following: Olanzapine and fluoxetine capsules : rhabdomyolysis and venous thromboembolic events (including pulmonary embolism and deep venous thrombosis). Fluoxetine : anosmia, aplastic anemia, cholestatic jaundice, drug reaction with eosinophilia and systemic symptoms (DRESS), eosinophilic pneumonia 3 , erythema multiforme, violent behavior 3 , atrial fibrillation 3 , cataract, cerebrovascular accident 3 , epidermal necrolysis, erythema nodosum, heart arrest 3 , hepatic failure/necrosis, hypoglycemia, hyposmia, kidney failure, memory impairment, optic neuritis, pulmonary hypertension, Stevens-Johnson syndrome. Olanzapine : diabetic coma, jaundice, random triglyceride levels of ≥1000 mg/dL, restless legs syndrome, stuttering 4 , salivary hypersecretion, allergic reaction (e.g., anaphylactoid reaction, angioedema, pruritus or urticaria), diabetic ketoacidosis, discontinuation reaction (diaphoresis, nausea or vomiting), Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). 3 These terms represent serious adverse events but do not meet the definition for adverse drug reactions. They are included here because of their seriousness. 4 Stuttering was only studied in oral and long acting injection (LAI) olanzapine formulations.

12.3 Pharmacokinetics Olanzapine and Fluoxetine — Fluoxetine (administered as a 60 mg single dose or 60 mg daily for 8 days) caused a small increase in the mean maximum concentration of olanzapine (16%) following a 5 mg dose, an increase in the mean area under the curve (17%) and a small decrease in mean apparent clearance of olanzapine (16%). In another study, a similar decrease in apparent clearance of olanzapine of 14% was observed following olanzapine doses of 6 or 12 mg with concomitant fluoxetine doses of 25 mg or more. The decrease in clearance reflects an increase in bioavailability. The terminal half-life is not affected, and therefore the time to reach steady-state should not be altered. The overall steady-state plasma concentrations of olanzapine and fluoxetine when given as the combination in the therapeutic dose ranges were comparable with those typically attained with each of the monotherapies. The small change in olanzapine clearance, observed in both studies, likely reflects the inhibition of a minor metabolic pathway for olanzapine via CYP2D6 by fluoxetine, a potent CYP2D6 inhibitor, and was not deemed clinically significant. Therefore, the pharmacokinetics of the individual components is expected to reasonably characterize the overall pharmacokinetics of the combination. Absorption and Bioavailability Olanzapine and Fluoxetine — Following a single oral 12 mg/50 mg dose of olanzapine and fluoxetine, peak plasma concentrations of olanzapine and fluoxetine occur at approximately 4 and 6 hours, respectively. The effect of food on the absorption and bioavailability of olanzapine and fluoxetine has not been evaluated. The bioavailability of olanzapine given as Zyprexa, and the bioavailability of fluoxetine given as Prozac were not affected by food. It is unlikely that there would be a significant food effect on the bioavailability of olanzapine and fluoxetine. Olanzapine — Olanzapine is well absorbed and reaches peak concentration approximately 6 hours following an oral dose. Food does not affect the rate or extent of olanzapine absorption when olanzapine is given as Zyprexa. It is eliminated extensively by first pass metabolism, with approximately 40% of the dose metabolized before reaching the systemic circulation. Fluoxetine — Following a single oral 40 mg dose, peak plasma concentrations of fluoxetine from 15 to 55 ng/mL are observed after 6 to 8 hours. Food does not appear to affect the systemic bioavailability of fluoxetine given as Prozac, although it may delay its absorption by 1 to 2 hours, which is probably not clinically significant. Distribution Olanzapine and Fluoxetine — The in vitro binding to human plasma proteins of olanzapine and fluoxetine in combination is similar to the binding of the individual components. Olanzapine — Olanzapine is extensively distributed throughout the body, with a volume of distribution of approximately 1000 L. It is 93% bound to plasma proteins over the concentration range of 7 to 1100 ng/mL, binding primarily to albumin and α 1 -acid glycoprotein. Fluoxetine — Over the concentration range from 200 to 1000 ng/mL, approximately 94.5% of fluoxetine is bound in vitro to human serum proteins, including albumin and α 1 -glycoprotein. The interaction between fluoxetine and other highly protein-bound drugs has not been fully evaluated [see Drug Interactions (7.7)] . Metabolism and Elimination Olanzapine and Fluoxetine — Olanzapine and Fluoxetine therapy yielded steady-state concentrations of norfluoxetine similar to those seen with fluoxetine in the therapeutic dose range. Olanzapine — Olanzapine displays linear pharmacokinetics over the clinical dosing range. Its half-life ranges from 21 to 54 hours (5th to 95th percentile; mean of 30 hr), and apparent plasma clearance ranges from 12 to 47 L/hr (5th to 95th percentile; mean of 25 L/hr). Administration of olanzapine once daily leads to steady-state concentrations in about 1 week that are approximately twice the concentrations after single doses. Plasma concentrations, half-life, and clearance of olanzapine may vary between individuals on the basis of smoking status, gender, and age [see Dosage and Administration (2.3) and Clinical Pharmacology (12.4)] . Following a single oral dose of 14 C-labeled olanzapine, 7% of the dose of olanzapine was recovered in the urine as unchanged drug, indicating that olanzapine is highly metabolized. Approximately 57% and 30% of the dose was recovered in the urine and feces, respectively. In the plasma, olanzapine accounted for only 12% of the AUC for total radioactivity, indicating significant exposure to metabolites. After multiple dosing, the major circulating metabolites were the 10-N-glucuronide, present at steady-state at 44% of the concentration of olanzapine, and 4´-N-desmethyl olanzapine, present at steady-state at 31% of the concentration of olanzapine. Both metabolites lack pharmacological activity at the concentrations observed. Direct glucuronidation and CYP450-mediated oxidation are the primary metabolic pathways for olanzapine. In vitro studies suggest that CYP1A2, CYP2D6, and the flavin-containing monooxygenase system are involved in olanzapine oxidation. CYP2D6-mediated oxidation appears to be a minor metabolic pathway in vivo , because the clearance of olanzapine is not reduced in subjects who are deficient in this enzyme. Fluoxetine — Fluoxetine is a racemic mixture (50/50) of R -fluoxetine and S -fluoxetine enantiomers. In animal models, both enantiomers are specific and potent serotonin uptake inhibitors with essentially equivalent pharmacologic activity. The S -fluoxetine enantiomer is eliminated more slowly and is the predominant enantiomer present in plasma at steady-state. Fluoxetine is extensively metabolized in the liver to its only identified active metabolite, norfluoxetine, via the CYP2D6 pathway. A number of unidentified metabolites exist. In animal models, S -norfluoxetine is a potent and selective inhibitor of serotonin uptake and has activity essentially equivalent to R - or S -fluoxetine. R -norfluoxetine is significantly less potent than the parent drug in the inhibition of serotonin uptake. The primary route of elimination appears to be hepatic metabolism to inactive metabolites excreted by the kidney. Clinical Issues Related to Metabolism and Elimination The complexity of the metabolism of fluoxetine has several consequences that may potentially affect the clinical use of olanzapine and fluoxetine. Variability in Metabolism — A subset (about 7%) of the population has reduced activity of the drug metabolizing enzyme CYP2D6. Such individuals are referred to as “poor metabolizers” of drugs such as debrisoquin, dextromethorphan, and the tricyclic antidepressants (TCAs). In a study involving labeled and unlabeled enantiomers administered as a racemate, these individuals metabolized S -fluoxetine at a slower rate and thus achieved higher concentrations of S -fluoxetine. Consequently, concentrations of S- norfluoxetine at steady-state were lower. The metabolism of R -fluoxetine in these poor metabolizers appears normal. When compared with normal metabolizers, the total sum at steady-state of the plasma concentrations of the 4 enantiomers was not significantly greater among poor metabolizers. Thus, the net pharmacodynamic activities were essentially the same. Alternative nonsaturable pathways (non-CYP2D6) also contribute to the metabolism of fluoxetine. This explains how fluoxetine achieves a steady-state concentration rather than increasing without limit. Because the metabolism of fluoxetine, like that of a number of other compounds including TCAs and other selective serotonin antidepressants, involves the CYP2D6 system, concomitant therapy with drugs also metabolized by this enzyme system (such as the TCAs) may lead to drug interactions [see Drug Interactions (7.7)] . Accumulation and Slow Elimination — The relatively slow elimination of fluoxetine (elimination half-life of 1 to 3 days after acute administration and 4 to 6 days after chronic administration) and its active metabolite, norfluoxetine (elimination half-life of 4 to 16 days after acute and chronic administration), leads to significant accumulation of these active species in chronic use and delayed attainment of steady state, even when a fixed dose is used. After 30 days of dosing at 40 mg/day, plasma concentrations of fluoxetine in the range of 91 to 302 ng/mL and norfluoxetine in the range of 72 to 258 ng/mL have been observed. Plasma concentrations of fluoxetine were higher than those predicted by single-dose studies, because the metabolism of fluoxetine is not proportional to dose. However, norfluoxetine appears to have linear pharmacokinetics. Its mean terminal half-life after a single dose was 8.6 days and after multiple dosing was 9.3 days. Steady-state levels after prolonged dosing are similar to levels seen at 4 to 5 weeks. The long elimination half-lives of fluoxetine and norfluoxetine assure that, even when dosing is stopped, active drug substance will persist in the body for weeks (primarily depending on individual patient characteristics, previous dosing regimen, and length of previous therapy at discontinuation). This is of potential consequence when drug discontinuation is required or when drugs are prescribed that might interact with fluoxetine and norfluoxetine following the discontinuation of fluoxetine.
