Background and Date of Approval
Dienogest is a synthetic progestin, often used in combination with estrogen in contraceptive pills and for the treatment of endometriosis. It was developed as a more selective progestin, aiming to provide effective contraception while minimising side effects.
Dienogest was first approved by regulatory agencies in the early 2000s for the treatment of endometriosis and later for use in birth control formulations. Its unique progestogenic action has made it a preferred option for treating conditions like endometriosis and heavy menstrual bleeding.
Mechanism of Action of undefined
Dienogest acts by binding to progesterone receptors in target tissues, mimicking the effects of natural progesterone. It suppresses ovulation, thickens cervical mucus, and alters the uterine lining, which reduces the likelihood of implantation. Additionally, it has an anti-inflammatory effect on the endometrium, making it particularly effective in managing conditions like endometriosis.
Uses of undefined
Dienogest is primarily prescribed for the following conditions:
- Endometriosis: It helps alleviate symptoms like pelvic pain and dysmenorrhea (painful periods) by reducing endometrial lesions and the associated inflammation.
- Contraception: When combined with estrogen, dienogest is used in birth control pills to prevent ovulation and reduce the chances of pregnancy.
- Menstrual Disorders: It is also used to treat irregular or heavy menstrual bleeding by stabilising the endometrial lining and regulating menstrual cycles.
undefined Drug administaration and Dosage available
Dienogest is available in oral tablet form and is typically administered once daily. The dosage varies depending on the condition being treated:
- For endometriosis, the standard dose is 2 mg per day, taken continuously without a break.
- In combination contraceptives, the dosage of dienogest may be part of a combined regimen with estrogen, and it’s typically taken for 21 days, followed by a 7-day break.
- The tablet should be taken with a glass of water, and it can be taken with or without food.
