Clindamycin & Clindamycin Phosphate, also known as the brand name Clindesse, faces a patent expiration on November 17, 2017. Clindamycin & Clindamycin Phosphate is a crucial treatment for Bacterial Vaginosis. With roughly 700,000 cases of Bacterial Vaginosis, also known as BV, in the US each year, this condition affects women of varying ages. Estimates suggest that roughly 1 in 3 women in the United States will develop a case of BV during their lifetime, with women being affected primarily during their reproductive years. Additionally, about 16 percent of pregnant women in the U.S. find Bacterial Vaginosis to be a common problem. This is a serious situation as pregnant women with Bacterial Vaginosis are at a substantially greater risk of preterm labor.
The microbiology of Bacterial Vaginosis represents a complex change in the vaginal flora, which is characterized by a reduction in the concentration of the normally dominant hydrogen-peroxide producing lactobacilli, as well as an increase in concentration of other organisms, particularly anaerobic gram negative rods. The administration of clindamycin administered either orally or intravaginally has proven effectual and safe. In fact, almost 80 percent of patients treated with clindamycin for Bacterial Vaginosis experience a high rate of clinical cure at a four week follow up. Topical vaginal therapy with a 2 percent clindamycin cream (5 g of cream containing 100 mg of clindamycin phosphate) is the recommended dose for Bacterial Vaginosis, to be administered as a seven day regimen. It is important for patients to know that Clindamycin cream should not be used concurrently with latex condoms, as it may weaken the condom.
Bacterial Vaginosis is diagnosed by the presence of homogeneous vaginal discharge, a presence of clue cells greater than 20 percent, absence of the normal vaginal lactobacilli and a vaginal pH greater than 4.5.
