A long acting injectable parasiticidal composition and the process for its preparation

摘要

Injectable, long acting parasiticidal composition which comprises enough ivermectin to achieve a final concentration of about 1% (w/w), benzilic alcohol, polyvinylpyrrolidone, N-metyl-2-pyrrolidone in a 40-65% proportion (v/w) of the total formulation and glycerin until completing final 100% weight. The process for its preparation involves mixing enough ivermectin to obtain a final concentration of about 1% (w/w) with benzilic alcohol and polyvinylpyrrolidone followed by the addition of the mixture to N-metyl-2-pyrrolidone, the latter in a 40-65% proportion (v/w) of the total of the formulation. The mixture is shaken until totally dissolved and glycerin is added until reaching 100% final weight.
