COMPOSITIONS BASED ON NOMOGESTROL DERIVATIVES, SUBCUTANEOUS IMPLANTS BASED ON THESE COMPOSITIONS, METHODS FOR THEIR MANUFACTURE AND APPLICATION AS CONTRACEPTIVES

摘要

The implants are used in pharmaceutical chemistry, especiallyin pharmacotechnology. They are efficient contraceptive agentshaving at least one-year period of effect, with minimum sideeffects. The implants are of different nature - hydrophobic,hydrophilic, biodegrading, and different types - space, uterine.They contain an efficient dose of a derivative of3,20-dioxy-6-methyl-17-acetoxy-19-norpregna-4,6-diene, eventuallyreplaced in 3td and/or 17th position, unified or mixed with onebiologically acceptable inter excipient.20 claims, 2 figures
