ANAGESTONE

Generic Name: ANAGESTONE

ABSTRACT -

Anagestone is a synthetic pregnane progestin parent compound; its clinically known ester, anagestone acetate, was historically used in combined oral contraceptive products. Anagestone acetate was withdrawn from use, and the parent compound itself is not a routine modern therapeutic agent. The chemical representation above corresponds to the clinically recognised acetate ester form associated with anagestone history.

DOSAGE - 

Dosage should be determined only by a qualified healthcare professional.

No modern approved standard dosing regimen is established for anagestone.

Historical contraceptive use involved anagestone acetate combinations, but these products are withdrawn or unavailable in most markets.

Do not use as contraception or hormone therapy unless a legally approved product and specialist direction exist.

DRUG INTERACTIONS–

  • Smoking and oestrogen-containing combinations increase vascular risk.

PREAUTIONS–

  • Assess cardiovascular risk factors before hormone exposure.
