Clinical Pharmacology

Nopoxypol is a non-ionic surface-active compound, its spermicidal effect is due to fragmentation and a decrease in sperm motility. It has bactericidal activity against gonococci and chlamydia. In vitro is active against HIV infections, but there are no clinical data on reducing the risk of HIV infection when using ponoxinol. Lactic acid has a beneficial effect on the normal microflora and vaginal mucosa.
When using a suppository, the concentration of ponoxinol in the vagina is on average 1-1.7%, which is sufficient for the manifestation of spermicidal activity.
The spermicidal action of the suppository occurs after its dissolution, approximately 10 minutes after insertion into the vagina, and lasts no more than 2 hours.
When using the drug does not form foam.

Data on the pharmacokinetics of ponoxinol in humans are absent.


Local contraception.


Active substance: Nonoxynol-9 - 120 mg;
