Spermicidal and antiviral properties of cholic acid: contraceptive efficacy of a new vaginal sponge (Protectaid) containing sodium cholate.
Cholic acid (sodium cholate) exhibits a strong spermicidal and antiviral [anti-human immunodeficiency virus (HIV)-1] activity. The same effects are observed for F-5 Gel, the active mixture of a new contraceptive sponge (Protectaid), which contains sodium cholate in association with low concentrations (0.5%) of nonoxynol-9 and benzalkonium chloride. Both cholic acid and the F-5 Gel exert a dose-dependent, in-vitro inhibitory effect (i) on the activity of HIV-1 associated reverse transcriptase in an acellular system and (ii) on the potential of HIV-1 efficiently to infect human lymphocytes. During 12 months use, the contraceptive efficacy of the 'Protectaid' sponge was 100% in 20 young women who had chosen this method for reasons of both contraception and anti-sexually transmitted disease. No side-effects were recorded throughout this period. Cervical cultures at 6-month intervals showed the presence of Mycoplasma hominis and Candida albicans in one or two cases. The combined spermicidal and anti-HIV properties of cholic acid reported in this paper and used in the 'Protectaid' sponge offer a new and modern protective method of contraception.
