title: A comparative study of Neo Sampoon, Ortho Vaginal Tablets and Emko Vaginal Tablets in Accra, Ghana.
abstract: Neo Sampoon is an effervescent contraceptive vaginal tablet manufactured in Japan that contains 60 mg of the spermicide menfegol. Ortho Vaginal Tablets (OVT) and Emko Vaginal Tablets (EVT), both containing 100 mg of the spermicide nonoxynol-9, were manufactured in the USA. The three products were compared in a randomized clinical trial conducted at the family planning clinics of the Korle-Bu Teaching Hospital and the Kotobaabi Polyclinic in Accra, Ghana. Three-hundred volunteers participated. At 12 months, the life-table pregnancy rates were 9.6, 11.3 and 12.5 per 100 women in the Neo Sampoon, OVT and EVT groups, respectively (p greater than 0.10). More EVT than Neo Sampoon or OVT users discontinued because of discomfort as well as for other product-related reasons (p less than 0.01). The most common reason for discontinuation was the temporary absence of sexual partner, with more than 40% of the women overall terminating for this reason. The 12-month life-table continuation rates per 100 women were higher for the Neo Sampoon group (62.4) than the OVT group (48.6) or the EVT group (38.5) (p less than 0.01). The effectiveness of the three products seems to be similar, but Neo Sampoon and OVT appear to be more acceptable than EVT in this Ghanaian population.
