LPS SR 300 Tablet contains 300 mg of natural micronized progesterone, a bioidentical hormone essential for 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, supporting early pregnancy, and preventing miscarriage in cases of luteal phase deficiency or assisted reproductive technologies. It is commonly prescribed for conditions such as amenorrhea, abnormal uterine bleeding, and as part of hormone replacement therapy in menopausal women to counteract estrogen-induced endometrial hyperplasia. Additionally, LPS SR 300 is utilized in the management of infertility and recurrent pregnancy loss. The natural micronized form enhances bioavailability and mimics endogenous progesterone activity, reducing the risk of adverse effects compared to synthetic progestins. Administration should follow medical guidance, considering patient-specific factors such as dosage, duration, and indication. Common side effects may include dizziness, headache, breast tenderness, and mood changes. Contraindications include known hypersensitivity to progesterone, active thromboembolic disorders, and certain hormone-sensitive cancers. Regular monitoring and follow-up are recommended to ensure therapeutic success and safety.
