MIOSTAT® (carbachol intraocular solution, USP) is a sterile balanced salt solution of carbachol for intraocular injection. The active ingredient is represented by the chemical structure:Established name:CarbacholChemical name:Ethanaminium, 2-[(aminocarbonyl)oxy]-N,N,Ntrimethyl-, chloride.Molecular Formula: C6H15CIN2O2Molecular Weight: 182.65Each mL contains: Active: carbachol 0.01%.Inactives: sodium chloride 0.64%, potassium chloride 0.075%, calcium chloride dehydrate 0.048%, magnesium chloride hexahydrate 0.03%, sodium acetate trihydrate 0.39%, sodium citrate dihydrate 0.17%, sodium hydroxide and/or hydrochloric acid (to adjust pH) and Water for Injection. pH range is 6.5-7.5.
Carbachol is a potent cholinergic (parasympathomimetic) agent which produces constriction of the iris and ciliary body resulting in reduction in intraocular pressure. The exact mechanism by which carbachol lowers intraocular pressure is not precisely known.
Indications And Usage
Intraocular use for obtaining miosis during surgery. In addition, MIOSTAT (carbachol intraocular solution, USP) reduces the intensity of intraocular pressure elevation in the first 24 hours after cataract surgery.
Should not be used in those persons showing hypersensitivity to any of the components of this preparation.
For single-dose intraocular use only. Discard unused portion. Intraocular carbachol 0.01% should be used with caution in patients with acute cardiac failure, bronchial asthma, peptic ulcer, hyperthyroidism, G.I. spasm, urinary tract obstruction and Parkinson's disease.The vial stopper contains natural rubber (latex) which may cause severe allergic reactions.
Use only if the container is undamaged.
Studies in animals to evaluate the carcinogenic potential have not been conducted.
Category C. There are no adequate and well-controlled studies in pregnant women. MIOSTAT® (carbachol intraocular solution, USP) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
It is not known if this medication is excreted in breast milk. Exercise caution when administering to a nursing woman.
Safety and efficacy in pediatric patients have not been established.
No overall differences in safety or effectiveness have been observed between elderly and younger patients.
Ocular: Corneal clouding, persistent bullous keratopathy, retinal detachment and postoperative iritis following cataract extraction have been reported.Systemic: Side effects such as flushing, sweating, epigastric distress, abdominal cramps, tightness in urinary bladder, and headache have been reported with topical or systemic application of carbachol.The following additional reactions have been identified during post-approval use of MIOSTAT (carbachol intraocular solution, USP) in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to MIOSTAT, or a combination of these factors, include: corneal edema, drug effect prolonged (miosis), eye inflammation, eye pain, intraocular pressure increased, ocular hyperemia, vision blurred, visual impairment, and vomiting.
Dosage And Administration
Aseptically remove the sterile vial from the blister package by peeling the backing paper and dropping the vial onto a sterile tray. Withdraw the contents into a dry sterile syringe, and replace the needle with an atraumatic cannula prior to intraocular instillation. No more than one-half milliliter should be gently instilled into the anterior chamber for the production of satisfactory miosis. It may be instilled before or after securing sutures. Miosis is usually maximal within two to five minutes after application.
