The full form of MPA injection is Medroxyprogesterone Acetate. It's a hormone used primarily as a long-acting contraceptive injection. Often, you'll see it referred to as depot medroxyprogesterone acetate (DMPA) when in injectable form. The injectable form is commonly known by brand names like Depo-Provera.
Understanding MPA Injection
MPA injections provide a highly effective method of contraception. A single injection provides protection for several months. This study highlights its use, while this resource details its implementation in healthcare programs.
- Mechanism: MPA works by suppressing ovulation, preventing the release of eggs from the ovaries.
- Administration: MPA is administered via injection, typically intramuscularly (into the muscle) or subcutaneously (under the skin), depending on the specific formulation (e.g., Depo-Provera, Depo-SubQ Provera 104). Pfizer's prescribing information offers details on dosage forms and strengths.
- Duration of Effect: The duration varies depending on the dosage and administration method, generally providing several months of contraceptive protection. This document details the formulation of a specific MPA injection.
- Long-Term Use: While effective, long-term use of MPA is associated with potential side effects, including changes in bone mineral density. This prescribing information notes potential side effects and long-term implications. This article examines ovulation suppression following subcutaneous administration of MPA.
Different Forms and Uses: While primarily known for contraception, MPA also has other therapeutic uses beyond its contraceptive application, though details of these applications are beyond the scope of this response.
