Antara injection refers to two distinct medical products: a contraceptive injection and a medication to lower cholesterol and triglycerides. The specific meaning depends on the context.
Antara as a Contraceptive Injection
Antara, also known as DMPA (Depot Medroxyprogesterone Acetate), is a long-acting, reversible contraceptive injection. It's administered intramuscularly every three months and prevents pregnancy by preventing ovulation. [This information is supported by multiple sources, including the UNFPA, NHM, and various news articles](https://india.unfpa.org/sites/default/files/pub-pdf/faq_for_asha_workers_english.pdf, https://nhmmp.gov.in/WebContent/FW/Guideline2017/Injectable_Manual.pdf, https://timesofindia.indiatimes.com/city/varanasi/antara-contraceptive-injection-a-popular-choice-for-family-planning-in-varanasi-district/articleshow/111673826.cms). It is a popular choice for family planning in some regions of India. A missed injection by more than four weeks necessitates a new injection immediately.
- Administration: Intramuscular injection every three months.
- Mechanism: Prevents ovulation.
- Reversibility: A woman's fertility returns after discontinuation.
Antara as a Lipid-Regulating Agent
Antara (fenofibrate) is a medication used to treat high cholesterol and high triglyceride levels. It's a fibrate, a type of lipid-regulating agent. Antara helps reduce cholesterol and triglycerides in the blood, thereby lowering the risk of atherosclerosis (clogged arteries). [This is confirmed by RxList and other sources](https://www.rxlist.com/antara-drug.htm, https://www.drugs.com/mtm/antara.html).
- Mechanism: Reduces cholesterol and triglycerides.
- Use: Treatment of high cholesterol and triglycerides.
- Benefits: Reduces the risk of cardiovascular disease.
It's crucial to specify which Antara injection you are referring to, as the applications and effects differ significantly.
