New Pregnancy Prevention Pills for You
Women, who are exploring new ways to prevent pregnancy, can now look at these options that are coming in the market.
Latest among the vendors is Watson Pharmaceuticals. It has announced the U.S. Food and Drug Administration (FDA) approval of an oral contraceptive (OC) product – claimed to be the first and only low dose oral contraceptive in chewable form.
Taken orally, once daily, the product is proven effective in lowering the risk of pregnancy, the company said Wednesday, Dec. 22.
Among the other OC options, Bayer HealthCare Pharmaceuticals has also announced that the FDA has approved its Beyaz – claimed to be the first and only OC approved to raise folate levels in women who choose an OC for birth control. (Read: Bayer Introduces New Oral Contraceptive)
Recently, FDA also approved ella (ulipristal acetate) tablets for emergency contraception. The prescription-only product prevents pregnancy when taken orally within 120 hours (five days) after a contraceptive failure or unprotected intercourse. (Read: FDA Approves ella for Emergency Contraception)
Watson’s new oral contraceptive is an alternative to currently available birth control pills. This pill’s dosing combination and proven 24-day, active hormone regimen is intended to provide users with a low level of breakthrough bleeding and short, light, predictable periods.

“We believe this product is an important addition to the oral contraceptive category, and that its characteristics will make it a desirable choice for women.”
The contraceptive product, licensed from a subsidiary of Warner Chilcott plc, will be actively marketed to physicians by Watson’s Global Brands division beginning in the second quarter 2011.

The approval of the oral contraceptive is based on data from a 12-month, Phase 3, multicenter, open-label study that evaluated the safety and efficacy of the product for pregnancy prevention.
Among 1,251 women between the ages of 18 and 35 who completed 12,297 treatment cycles, the pregnancy rate (Pearl Index) in women was 2.01 pregnancies per 100 women-years of treatment.
In addition, women in the clinical trial reported short (mean duration of 3.7 days), predictable periods, with withdrawal bleeding beginning approximately on Day 27 or 28.

The company informs that nearly 11 million U.S. women use oral contraceptives to prevent pregnancy, and “the Pill” is the most common contraceptive method among women under 30 who practice contraception.
The U.S. oral contraceptive market currently exceeds $4 billion annually and is dominated (86%) by combination (estrogen-progestin) pills.
