Yaz (Drospirenone/Ethinylestradiol)

Product Overview

Yaz is a widely used combined oral contraceptive pill (COCP) that contains two of the most active hormonal components: Drospirenone 3 mg and Ethinylestradiol 0.02 mg. The latest contraceptive pill with a low dose can be effective in preventing pregnancies, in addition to other advantages such as the management of menstrual cycles, reduction in acne, and treatment of premenstrual disorder (PMDD).

Yaz is most well-known for its distinctive progestin ingredient, Drospirenone, which is structurally similar to spironolactone. It has mild diuretic and anti-androgenic characteristics, which distinguish its use from that of other oral contraceptives.

Active Ingredients

• Drospirenone 3 mg: A synthetic progestin with anti-androgenic and anti-mineralocorticoid activity
• Ethinylestradiol 0.02 mg: A Synthetic estrogens that help to regulate menstrual cycles and boost contraceptive efficacy

Indications

Yaz is prescribed for:

• The prevention of pregnancies as an effective oral contraceptive
• Treatment for mild acne vulgaris among females seeking contraception
• Management of premenstrual dysphoric disorder (PMDD) symptoms, including mood swings, irritability, and physical discomfort
• Regulation of menstrual cycles and reduction of menstrual pain (dysmenorrhea)

Mechanism of Action

Yaz can prevent the onset of pregnancy, primarily through inhibiting Ovulation. Drospirenone in combination with ethinylestradiol blocks the mid-cycle surge of the hormone known as luteinizing hormone (LH) as well as follicle-stimulating hormone (FSH), which prevents the release of eggs in the ovaries.

In addition, it increases the thickness of cervical mucus, which makes it harder for sperm to get into the uterus. It also alters the lining of the endometrium and reduces the chances of implantation.

Drospirenone’s anti-androgenic properties aid in reducing acne through reducing sebum production as well as blocking the androgen receptors.

The anti-mineralocorticoid properties counteract water retention, which can reduce bloating and weight gain often associated with contraceptive pills.
