About This Medication

MembraneBlue - Description. MembraneBlue™ (trypan blue ophthalmic solution) 0.15% is a sterile solution of trypan blue (an acid di-azo group dye) for intraocular ophthalmic use. MembraneBlue selectively stains epiretinal membranes during ophthalmic surgical vitrectomy procedures. Each mL of MembraneBlue 0.15% contains: 1.5 mg trypan blue; 1.9 mg sodium mono-hydrogen orthophosphate (Na 2 HPO 4 •2H 2 O); 0.3 mg sodium di-hydrogen orthophosphate (NaH 2 PO 4 •2H 2 O); 8.2 mg sodium chloride (NaCl); and water for injection. The pH is 7.3 - 7.6. The osmolality is 257 - 314 mOsm/kg. The drug substance trypan blue has the chemical name 3,3'-[(3,3'-dimethyl-4,4'-biphenylylene) bis (azo)] bis (5-amino-4-hydroxy-2,7-naphthalenedisulfonic acid) tetra sodium salt, a molecular weight of 960.8, a molecular formula of C 34 H 24 N 6 Na 4 O 14 S 4 , and has the following chemical structure: Chemical structure MembraneBlue

Показания и Применение

MembraneBlue 0.15% - Indications & Usage Section MembraneBlue™ 0.15% is indicated for use as an aid in ophthalmic surgery by staining the epiretinal membranes during ophthalmic surgical vitrectomy procedures, facilitating removal of the tissue in adults and pediatric patients. These highlights do not include all the information needed to use MEMBRANEBLUE™ safely and effectively. See full prescribing information for MEMBRANEBLUE. MEMBRANEBLUE (trypan blue ophthalmic solution) 0.15%, for intraocular ophthalmic use Initial U.S. Approval: 2004 MembraneBlue is a diagnostic dye indicated for use as an aid in ophthalmic posterior surgery by staining the epiretinal membranes during ophthalmic surgical vitrectomy procedures, facilitating removal of epiretinal tissue in adults and pediatric patients

Как это работает

MembraneBlue 0.15% - Mechanism of action section. MembraneBlue 0.15% selectively stains membranes in the human eye during posterior surgery, such as epiretinal membranes (ERM) and Internal Limiting Membranes (ILM).

Дозировка и Способ Применения

MembraneBlue 0.15% - Dosage & administration section MembraneBlue 0.15% is packaged in a single-patient-use syringe filled to a volume of 0.5 mL. Make sure the plunger moves smoothly before use. Prime the syringe prior to use by retracting the plunger before injecting the fluid. Alternatively, twist the plunger into the stopper in a clockwise motion until tight. Once tight, continue turning the plunger in a clockwise motion until the stopper rotates freely within the syringe, two or three rotations. The syringe is now primed and suitable for injection. Before injection of MembraneBlue perform a “fluid-air exchange” (i.e., filling the entire vitreous cavity with air, to prevent aqueous dilution of MembraneBlue). MembraneBlue is carefully applied to the retinal membrane using a blunt cannula attached to the MembraneBlue syringe, without allowing the cannula to contact or damage the retina. Sufficient staining is expected on contact with the membrane. All excess dye should be removed from the vitreous cavity before performing an air-fluid exchange, to prevent unnecessary spreading of the dye. MembraneBlue can also be injected directly in a BSS filled vitreous cavity (instead of injecting under air). Clinical use demonstrated that, after complete vitreous and posterior hyaloid removal, sufficient staining is achieved after 30 seconds of application under BSS. MembraneBlue is intended to be applied directly on the areas where membranes could be present, staining any portion of the membrane which comes in contact with the dye. The dye does not penetrate the membrane. Prior to injection of MembraneBlue, perform a “fluid-air exchange” (i.e., fill the entire vitreous cavity with air). Carefully apply MembraneBlue to epiretinal membranes using a blunt cannula and remove all excess dye. OR Inject MembraneBlue directly in a BSS filled-vitreous cavity. Wait 30 seconds and remove all excess dye. (2)

Side Effects Overview

MembraneBlue 0.15% - Adverse reactions section Adverse reactions reported following use of MembraneBlue 0.15% include discoloration of high water content hydrogen intraocular lenses [see Contraindications] and inadvertent staining of the posterior lens capsule and vitreous face. Staining of the posterior lens capsule or staining of the vitreous face is generally self limited, lasting up to one week. Most common adverse reactions include discoloration of high water content hydrogen intraocular lenses and inadvertent staining of the posterior lens capsule and vitreous face.
