Contraindications{{See also|Progestin#Contraindications}}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.[13] Overdose{{See also|Progestin#Overdose}}Contraindications{{See also|Progestin#Interactions}}PharmacologyPharmacodynamicsGestodene is a highly potent progestogen, and also possesses weak androgenic, antimineralocorticoid, and glucocorticoid activity.[14][15][16] Due to its progestogenic activity, it has antigonadotropic and functional antiestrogenic effects.[14] The medication has little or no estrogenic and no antiandrogenic activity.[14]
Progestogenic activityGestodene is a progestogen, and hence is an agonist of the progesterone receptor.[14] Based on the dosage necessary to inhibit ovulation in women, gestodene is the most potent of all of the currently used oral contraceptive progestogens.[17][18][19] The oral dosage of gestodene required for ovulation inhibition is 30 or 40 μg per day.[18][20] This is about 10,000 times lower than the oral dosage of progesterone required to inhibit ovulation (300 mg/day).[16][14] A dosage of gestodene of 75 μg/day is used in contraceptives.[19] Androgenic activityGestodene 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).[21] 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).[21] In addition, no difference in acne incidence has been observed with oral contraceptives containing gestodene and oral contraceptives containing desogestrel.[22] Gestodene may also act to some extent as a 5α-reductase inhibitor.[14][21] Taken together, like desogestrel, gestodene appears to have a low potential for androgenic effects.[21] Glucocorticoid activityGestodene has relatively high affinity for the glucocorticoid receptor, about 27% of that of the corticosteroid dexamethasone.[14] It has weak glucocorticoid activity.[14] {{Glucocorticoid activity of selected steroids in vitro}}Antimineralocorticoid activityGestodene has very high affinity for the mineralocorticoid receptor (MR), but has only a relatively weak antimineralocorticoid effect that is comparable to that of progesterone.[21] Other activitiesAlthough 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.[23] Gestodene binds to SHBG with relatively high affinity; it is 75% bound to the protein in circulation.[16][21] Gestodene shows some inhibition of cytochrome P450 enzymes in vitro, and has greater potency in this action compared to other progestins ({{abbrlink|IC50|half-maximal inhibitory concentration}} = 5.0 µM).[14][1] The medication also shows some inhibition of 5α-reductase in vitro (14.5% at 0.1 µM, 45.9% at 1.0 µM).[14] Like with cytochrome P450 inhibition, gestodene was more potent in this action compared to other progestins, including desogestrel and levonorgestrel.[14][21] PharmacokineticsThe oral bioavailability of gestodene has been found to range from 87 to 111%, with a mean of 96%.[24][1][2][4] Unlike other third-generation progestins like desogestrel and norgestimate, gestodene is not a prodrug.[24][25] Peak levels of gestodene occur within 1 to 4 hours after an oral dose, but usually within 1 to 2 hours.[24] 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][24] 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.[24] The biological half-life of gestodene is 12 to 15 hours.[1][4] Gestodene is eliminated 50% in urine and 33% in feces.[24] Of gestodene excreted in urine, 25% is in the form of glucuronide conjugates, 35% is as sulfate conjugates, and 25% is unconjugated.[24] Chemistry{{See also|List of progestogens}}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.[3][26] 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.[27] 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.[28][29] HistoryGestodene was first synthesized in 1975.[30] It was introduced for medical use, specifically in combination with ethinylestradiol as a combined oral contraceptive, in 1987.[31] 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.[5][26] Society and cultureGeneric namesGestodene is the generic name of the drug and its {{abbrlink|INN|International Nonproprietary Name}}, {{abbrlink|USAN|United States Adopted Name}}, {{abbrlink|BAN|British Approved Name}}, and {{abbrlink|DCF|Dénomination Commune Française}}.[3][4][26] It is also known by its developmental code name SHB-331.[3][26]Brand namesGestodene is marketed as a contraceptive in combination with ethinylestradiol under a variety of brand names including Femoden, Femodene, Femodette, Gynera, Harmonet, Lindynette, Logest, Meliane, Millinette, Minesse, Minulet, Mirelle, and Triadene as well as many others.[26] It is marketed for use in menopausal hormone therapy in combination with estradiol under the brand names Avaden, Avadene, and Convaden.[5][26] AvailabilityGestodene is marketed in the United Kingdom, Ireland, elsewhere throughout Europe, South Africa, Australia, Latin America, Asia, and elsewhere in the world.[26] It is not listed as being marketed in the United States, Canada, New Zealand, Japan, South Korea, India, or certain other countries.[26] Gestodene is marketed for use specifically in menopausal hormone therapy only in a few countries, including Colombia, Ecuador, Mexico, Peru, and Portugal.[26] References1. ^1 2 3 {{cite journal | vauthors = Stanczyk FZ | title = Pharmacokinetics and potency of progestins used for hormone replacement therapy and contraception | journal = Rev Endocr Metab Disord | volume = 3 | issue = 3 | pages = 211–24 | year = 2002 | pmid = 12215716 | doi = 10.1023/A:1020072325818| url = }} 2. ^1 {{cite journal | vauthors = Fotherby K | title = Bioavailability of orally administered sex steroids used in oral contraception and hormone replacement therapy | journal = Contraception | volume = 54 | issue = 2 | pages = 59–69 | date = August 1996 | pmid = 8842581 | doi = 10.1016/0010-7824(96)00136-9 | url = }} 3. ^1 2 3 {{cite book|author=J.
