Progestasert is available in which dosage form?

Progestasert is a brand of hormonal intrauterine device (IUD) used primarily for contraception and to manage certain gynecological conditions. As an IUD, it is a T-shaped device that is inserted into the uterus, where it releases a progestin hormone called progesterone to prevent ovulation and to thin the uterine lining. This method of delivery allows for long-term contraception with one device typically being effective for several years.

The other options do not represent the correct dosage form for Progestasert. Suppositories are designed for insertion into the rectum or vagina, achieving local or systemic effects; aerosols are used for inhalation or topical application; and tablets are oral medications. Each of these forms of medication has different pharmacokinetics and uses, but Progestasert's unique mechanism and delivery as an IUD is what distinguishes it in this context.
