Gestodene, sold under the brand names Femodene and Minulet among others, is a progestin medication which is used in birth control pills for women.[5][6] It is also used in menopausal hormone therapy.[7] The medication is available almost exclusively in combination with an estrogen.[8] It is taken by mouth.[6][9]

Side effects of the combination of an estrogen and gestodene include menstrual irregularities, headaches, nausea, breast tenderness, mood changes, and others.[citation needed] Gestodene is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[10][11] It has weak androgenic activity, weak antimineralocorticoid activity, and weak glucocorticoid activity.[10][11]

Gestodene was discovered in 1975 and was introduced for medical use, specifically in birth control pills, in 1987.[4][12] It was subsequently introduced for use in menopausal hormone therapy as well.[7][8] Gestodene is sometimes referred to as a "third-generation" progestin.[13] It is marketed in birth control pills widely throughout the world, whereas it is available for use in menopausal hormone therapy only a few countries.[8][7] Gestodene is not approved in the United States.[14][15]

Medical uses

Gestodene is neutral in terms of androgenic activity, meaning that contraceptive pills containing gestodene do not exhibit the androgenic side effects (e.g., acne, hirsutism) sometimes associated with second-generation contraceptive pills such as those containing levonorgestrel.[16]

The estrogen dosage in third-generation contraceptive pills (including those containing gestodene) is lower than that in second-generation oral contraceptives, reducing the likelihood of weight gain, breast tenderness, and migraine.[17]

Third-generation oral contraceptives are also suitable for use in patients with diabetes or lipid disorders because they have minimal impact on blood glucose levels and the lipid profile.[18]

Gestodene is also available in combination with estradiol for use in menopausal hormone therapy.[7][8]

Available forms

Contraceptive products containing gestodene include:

  • Melodene-15, Mirelle, and Minesse which contain 15 μg of ethinylestradiol and 60 μg of gestodene;
  • Meliane, Sunya, Femodette, and Millinette 20/75 which contain 20 μg of ethinylestradiol and 75 μg of gestodene; and
  • Gynera, Minulet, Femoden, Femodene, Katya and Millinette 30/75 which contain 30 μg of ethinylestradiol and 75 μg of gestodene.[19]

Side effects

See also: Progestin § Side effects

Women who take oral contraceptives containing gestodene are 5.6 times as likely to develop venous thromboembolism than women who do not take any contraceptive pill, and 1.6 times as likely to develop venous thromboembolism compared to women taking oral contraceptives containing levonorgestrel.[20]

Pharmacology

Pharmacodynamics

Gestodene is a highly potent progestogen, and also possesses weak androgenic, antimineralocorticoid, and glucocorticoid activity.[9][10][11] Due to its progestogenic activity, it has antigonadotropic and functional antiestrogenic effects.[9] The medication has little or no estrogenic and no antiandrogenic activity.[9]

Sources: [9]

Progestogenic activity

Gestodene is a progestogen, and hence is an agonist of the progesterone receptor.[9] Based on the dosage necessary to inhibit ovulation in women, gestodene is the most potent of all of the currently used oral contraceptive progestogens.[21][22][23] The oral dosage of gestodene required for ovulation inhibition is 30 or 40 μg per day.[22][24] This is about 10,000 times lower than the oral dosage of progesterone required to inhibit ovulation (300 mg/day).[11][9] A dosage of gestodene of 75 μg/day is used in contraceptives.[23]

Androgenic activity

Gestodene has relatively high affinity for the androgen receptor (AR), with twice that of levonorgestrel (which is known to be one of the more androgenic 19-nortestosterone derivatives).[25] However, the ratio of progestogenic to androgenic effects of gestodene is distinctly higher than that of levonorgestrel, and the increase in sex hormone-binding globulin (SHBG) levels (a marker of androgenicity) produced by oral contraceptives containing gestodene is slightly less than that produced by oral contraceptives containing desogestrel (which is known to be one of the more weakly androgenic 19-nortestosterone derivatives).[25] In addition, no difference in acne incidence has been observed with oral contraceptives containing gestodene and oral contraceptives containing desogestrel.[26] Gestodene may also act to some extent as a 5α-reductase inhibitor.[9][25] Taken together, like desogestrel, gestodene appears to have a low potential for androgenic effects.[25]

Glucocorticoid activity

Gestodene has relatively high affinity for the glucocorticoid receptor, about 27% of that of the corticosteroid dexamethasone.[9] It has weak glucocorticoid activity.[9]

Antimineralocorticoid activity

Gestodene has very high affinity for the mineralocorticoid receptor (MR), but has only a relatively weak antimineralocorticoid effect that is comparable to that of progesterone.[25]

Other activities

Although gestodene does not bind to the estrogen receptor itself, the drug may have some estrogenic activity, and this would appear to be mediated by its weakly estrogenic metabolites 3β,5α-tetrahydrogestodene and to a lesser extent 3α,5α-tetrahydrogestodene.[28]

Gestodene binds to SHBG with relatively high affinity; it is 75% bound to the protein in circulation.[11][25]

Gestodene shows some inhibition of cytochrome P450 enzymes in vitro, and has greater potency in this action compared to other progestins (IC50Tooltip half-maximal inhibitory concentration = 5.0 μM).[9][1] The medication also shows some inhibition of 5α-reductase in vitro (14.5% at 0.1 μM, 45.9% at 1.0 μM).[9] Like with cytochrome P450 inhibition, gestodene was more potent in this action compared to other progestins, including desogestrel and levonorgestrel.[9][25]

Pharmacokinetics

The oral bioavailability of gestodene has been found to range from 87 to 111%, with a mean of 96%.[1][2][3][4] Unlike other third-generation progestins like desogestrel and norgestimate, gestodene is not a prodrug.[1][29] Peak levels of gestodene occur within 1 to 4 hours after an oral dose, but usually within 1 to 2 hours.[1] The plasma protein binding of gestodene is 98%.[4] It is bound 64% to sex hormone-binding globulin and 34% to albumin, with 2% circulating freely.[4] Gestodene is metabolized in the liver via reduction of the δ4-3-keto group to form 3,5-tetrahydrogenated metabolites (major pathway) and via hydroxylation at the C1, C6, and C11 positions (substantial).[4][1] In spite of differing from it only by the presence of an additional double bond between the C15 and C16 positions, gestodene is not metabolized into levonorgestrel in the body.[1] The biological half-life of gestodene is 12 to 15 hours.[2][4] Gestodene is eliminated 50% in urine and 33% in feces.[1] Of gestodene excreted in urine, 25% is in the form of glucuronide conjugates, 35% is as sulfate conjugates, and 25% is unconjugated.[1]

Chemistry

Gestodene, also known as 17α-ethynyl-18-methyl-19-nor-δ15-testosterone, as well as 17α-ethynyl-18-methylestra-4,15-dien-17β-ol-3-one or 13β-ethyl-18,19-dinor-17α-pregna-4,15-dien-20-yn-17β-ol-3-one, is a synthetic estrane steroid and a derivative of testosterone.[5][8] It is more specifically a derivative of norethisterone (17α-ethynyl-19-nortestosterone) and is a member of the gonane (18-methylestrane) subgroup of the 19-nortestosterone family of progestins.[30] Gestodene is almost identical to levonorgestrel in terms of chemical structure, differing only in having an additional double bond between the C15 and C16 positions, and for this reason is also known as δ15-norgestrel or as 15-dehydronorgestrel.[31][32]

History

Gestodene was first synthesized in 1975.[4] It was introduced for medical use, specifically in combination with ethinylestradiol as a combined oral contraceptive, in 1987.[12] The medication was introduced for use in menopausal hormone therapy in combination with estradiol in some countries such as in Europe and Latin America years later.[7][8]
