Procedure

In 3.0 ml of 30% gelatin (dissolved by warming) is dissolved 50 mg of pridinol methanesulfonate and the solution is added to 10 ml of a 30% dichloromethane solution of lactic acid-glycolic acid copolymer (78.1/21.9, average mol. wt. 10,000). The mixture is then worked up in the same manner as Example 1 to give pridinol ethanesulfonate microcapsules for injection.
