cervidil - Medication Listings

CERVIDIL (dinoprostone) vaginal insert contains dinoprostone, a prostaglandin analog. Each vaginal insert contains 10 mg of dinoprostone in 241 mg of a cross-linked polyethylene oxide/urethane polymer (hydrogel polymer) that is semi-opaque, beige colored, flat, rectangular in shape with rounded corners and measuring 29 mm by 9.5 mm by 0.8 mm. The vaginal insert is contained within a pouch of an off-white knitted polyester yarn retrieval system. When placed in a moist environment, the yarn absorbs water, swells, and releases the enclosed dinoprostone. The knitted polyester retrieval system has a long tape-like end that is designed to aid retrieval of CERVIDIL at the end of the dosing interval or earlier if clinically indicated. The finished product is a controlled-release formulation that has been found to release dinoprostone in vivo at a rate of approximately 0.3 mg per hour. The chemical name for dinoprostone (known as prostaglandin E 2 or PGE 2 ) is 11α,15S-dihydroxy-9-oxo-prosta-5Z,13E-dien-1-oic acid and the structural formula is represented below: The molecular formula is C 20 H 32 O 5 and its molecular weight is 352.47. Dinoprostone occurs as a white to off-white crystalline powder. It has a melting point within the range of 65° to 69°C. Dinoprostone is soluble in ethanol and in 25% ethanol in water.
