Routes Oral

Dienogest is an orally active synthetic progesterone (or progestin).[1] It is available for use as an oral contraceptive in combination with ethinylestradiol. It has antiandrogenic activity and as a result can improve androgenic symptoms.[2] It is a non-ethinylated progestin which is structurally related to testosterone.[4]

 History

Dienogest was synthesised in 1979 in Jena, Germany under the leadership of Prof. Kurt Ponsold, was initially referred to as STS 557.[6][7] It was found that its potency was 10 times that of levonorgestrel.[8] The first product on the market to contain dienogest as a contraceptive pill Valette in 1995 made by Jenapharm.[9] It has been little used outside of Germany.[10]

 Indications

 Contraception

Dienogest is used primarily as a contraceptive in combination with ethinylestradiol. It is given as a tablet containing 2 mg of dienogest and 30 μg of ethinylestradiol.[11] The minimum dose required to inhibit ovulation has been found to be approximately 1 mg[12]

 Pharmacodynamics

 Progestational Activity

Dienogest has moderate affinity for the progesterone receptor in human uterus tissue, in vitro, about 10% that of progesterone.[13]

 Inhibition of Ovulation

The minimum effective dose of oral dienogest required to inhibit ovulation is 1 mg/day.[14] The inhibition of ovulation by dienogest occurs mainly via peripheral action as opposed to central action on gonadotrophin secretion.[2] Oral treatment of dienogest 2 mg/day in cyclical women reduced serum progesterone levels to anovulatory levels, however serum levels of lutenising hormone and follicle-stimulating hormone are not significantly altered.[14]

 Adverse effects

Adverse effects associated with dienogest are the same as those expected of a progestogen.[2] These include weight gain, increased blood pressure, breast tenderness and nausea.[15] It produces no androgenic side effects and has little effect on metabolic and lipid haemostatic parameters.[16]
