Ladagest SR 200 Tablet contains Progesterone 200 mg, a naturally occurring steroid hormone essential in regulating the menstrual cycle and maintaining pregnancy. This sustained-release formulation ensures a gradual and consistent release of progesterone, optimizing therapeutic efficacy and minimizing fluctuations in hormone levels. Progesterone plays a critical role in preparing the endometrium for implantation of the fertilized ovum and supports early pregnancy by maintaining the uterine lining. Ladagest SR 200 is primarily indicated for the treatment of progesterone deficiency-related conditions such as irregular menstruation, luteal phase defects, and threatened or recurrent miscarriage. It is also utilized in hormone replacement therapy (HRT) for menopausal women to counteract the effects of estrogen on the endometrium, reducing the risk of endometrial hyperplasia. Additionally, this medication may be prescribed in assisted reproductive technologies (ART) to support the luteal phase. The sustained-release mechanism allows for convenient once-daily dosing, improving patient compliance. Common side effects may include headache, breast tenderness, dizziness, and mild gastrointestinal disturbances. Contraindications include known hypersensitivity to progesterone, unexplained vaginal bleeding, and certain hormone-sensitive cancers. Use should be under strict medical supervision with appropriate monitoring to ensure safety and effectiveness.
