Abstract
A pharmaceutical product which includes two-chambers, one having a buffered diluent and the other having acetylcholine. Upon mixing the chamber contents, a buffered efficacious acetylcholine product is prepared for post-surgical ophthlamic injection. Another embodiment of the invention is a method of providing an acetylcholine product which has a substantially consistent final pH without substantial degradation of the acetylcholine. The method involves storing an unbuffered acetylcholine separate from a diluent solution which has been buffered, and mixing prior to use.
