To identify any toxicity on the vaginal epithelium, liver and kidney following UniPron administration, ten healthy female olive baboons (Papio anubis) of reproductive age and of proven fertility were used.
Five baboons were each treated with 15g of UniPron intravaginally twice a week for 20-weeks and venous blood collected before and after each treatment. Venous blood was collected from five control animals as in the experimental females, but these control animals were not given any treatment. The endpoints that were evaluated included clinical chemistry profiles on kidney and liver functions and vaginal histopathology. Female baboons treated with 15g of UniPron intravaginally showed no detectable adverse effects on clinical chemistry profiles investigated and vaginal histopathology.
Repeated intravaginal exposure of female baboons to UniPron did not induce detectable vaginal irritation and there were no detectable histological changes. We conclude that administration of UniPron
into baboon vagina did not cause any detectable toxicity (Afr J Reprod Health 2009; 13[4]:95-104).
