Miochol TM -E (acetylcholine chloride intraocular solution) is a parasympathomimetic preparation for intraocular use. It is packaged in a blister pack containing one vial and one diluent ampule. The vial contains 20 mg acetylcholine chloride and 56 mg mannitol. The accompanying ampule contains 2 mL of a modified diluent of calcium chloride dihydrate, magnesium chloride hexahydrate, potassium chloride, sodium acetate trihydrate, and sterile water for injection. The reconstituted liquid will be a sterile isotonic solution (275-330 milliosmoles/kg) containing 20 mg acetylcholine chloride (1:100 solution) and 2.8% mannitol. The pH range is 5.0-8.2. Mannitol is used in the process of lyophilizing acetylcholine chloride, and is not considered an active ingredient. The chemical name for acetylcholine chloride, C 7 H 16 ClNO 2 , is Ethanaminium, 2-(acetyloxy) -N,N,N -trimethyl-, chloride and is represented by the following chemical structure: ChemStructure
To obtain miosis of the iris in seconds after delivery of the lens in cataract surgery, in penetrating keratoplasty, iridectomy, and other anterior segment surgery where rapid miosis may be required.
Miochol TM -E (acetylcholine chloride intraocular solution) is instilled into the anterior chamber before or after securing one or more sutures. Instillation should be gentle and parallel to the iris face and tangential to pupil border. If there are no mechanical hindrances, the pupil starts to constrict in seconds and the peripheral iris is drawn away from the angle of the anterior chamber. Any anatomical hindrance to miosis must be released to permit the desired effect of the drug. In most cases, 0.5 to 2 mL produces satisfactory miosis. Note that the syringe filter supplied with Miochol-E has a priming volume of 0.6 mL (approximately). In cataract surgery, use Miochol-E only after delivery of the lens. Aqueous solutions of acetylcholine chloride are unstable. Prepare solution immediately before use. Do not use solution that is not clear and colorless. Discard any solution that has not been used.
Miochol-E is contraindicated in persons with a known hypersensitivity to any component of this product.
Infrequent cases of corneal edema, corneal clouding, and corneal decompensation have been reported with the use of intraocular acetylcholine. Adverse reactions have been reported rarely, which are indicative of systemic absorption. These include bradycardia, hypotension, flushing, breathing difficulties, and sweating. To report SUSPECTED ADVERSE REACTIONS, contact Bausch & Lomb Incorporated at 1-800-553-5340 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
DO NOT GAS STERILIZE. If blister or peelable backing is damaged or broken, sterility of the enclosed vial and ampule cannot be assured. Open under aseptic conditions only.
