Pfizer contraceptive OK'd for added use
FDA approves use of injectable drug to treat pain for a gynecological condition.

NEW YORK (CNN/Money) - Pfizer Inc. said Tuesday that the Food and Drug Administration has approved its depo-subQ provera 104 birth control drug for use against pain for a gynecological condition as well.

Pfizer (Research) said the injectable contraceptive can be used to treat pain for endometriosis, a condition that occurs when excess uterine tissue migrates to the ovaries and other areas of the body. The condition occurs in 10 percent of women and is one of the top causes of infertility, the company said.

Pfizer received regulatory approval for the new use of the drug Friday, according to company spokesman Daniel Watts. He said marketing for the new use will begin in May but he did not provide a revenue projection.

Watts said the contraceptive raised $200 million in revenue last year.

The drug is an improved version of the contraceptive depo provera, which was developed in the 1960s and initially used overseas. Depo provera was submitted to the FDA in the 1970s, but animal studies raised questions about its potential to cause breast cancer and the drug did not receive regulatory approval until 1992.  Top of page
