Demegestone , sold under the brand nameLutionex , is aprogestin medication which was previously used to treatluteal insufficiency but is now no longer marketed.[ 3] [ 4] [ 5] [ 6] [ 7] It is takenby mouth .[ 2] [ 1]
Demegestone is a progestin, or asynthetic progestogen , and hence is anagonist of theprogesterone receptor , thebiological target of progestogens likeprogesterone .[ 6] [ 2] [ 8] It has noandrogenic activity.[ 2]
Demegestone was first described in 1966 and was introduced for medical use inFrance in 1974.[ 3] [ 4] It has only been marketed in France, and has since been discontinued in this country.[ 5] [ 4]
Demegestone has been used to treatluteal insufficiency .[ 7] It has also been studied in combination withestrogens , such asmoxestrol , as anoral contraceptive and treatment forinfertility .[ 1] [ 9] [ 10]
Demegestone is aprogestogen , and hence is anagonist of theprogesterone receptor (PR).[ 6] [ 8] [ 2] It is a highlypotent progestogen, showing 50 times the potency ofprogesterone in theClauberg test .[ 2] Theovulation -inbhiting dosage of demegestone is 2.5 mg/day, while theendometrial transformation dosage is 100 mg per cycle.[ 11] The medication is devoid ofandrogenic activity,[ 2] and instead has someantiandrogenic activity.[ 12] Demegestone has lowaffinity for theglucocorticoid receptor .[ 13] In a particularbioassay , both demegestone and progesterone showedantiglucocorticoid rather thanglucocorticoid activity.[ 14] The majormetabolite of demegestone, a 21-hydroxylated metabolite, is a moderately potent progestogen (4 times the potency of progesterone) and a weakmineralocorticoid (2% of the potency ofdeoxycorticosterone ).[ 2]

Demegestone has goodbioavailability .[ 2] The initialvolume of distribution of demegestone is 31 L.[ 2] Demegestone ismetabolized byhydroxylation at the C21, C1, C2, and C11 positions, which is eventually followed by A-ringaromatization after 1,2-dehydration .[ 2] The major metabolite of demegestone is a 21-hydroxy derivative .[ 2] Themetabolic clearance rate of demegestone is 20 L/h.[ 2] Itsbiological half-lives are 2.39 and 0.24 hours withintravenous injection .[ 2] Demegestone and/or its metabolites areexcreted , at least in part, inurine .[ 2]
Demegestone, also known as 17α-methyl-δ9 -19-norprogesterone or as 17α-methyl-19-norpregna-4,9-diene-3,20-dione, is asynthetic norpregnane steroid and aderivative ofprogesterone .[ 3] [ 4] [ 6] It is specifically a combined derivative of17α-methylprogesterone and19-norprogesterone , or of17α-methyl-19-norprogesterone .[ 3] [ 4] [ 6] Related derivatives of 17α-methyl-19-norprogesterone includepromegestone andtrimegestone .[ 3] [ 6]
Demegestone was first described in the literature in 1964 and was introduced for medical use in 1974 inFrance .[ 3] [ 4] It was developed byRoussel Uclaf .[ 4]
Society and culture [ edit ] Demegestone is thegeneric name of the drug and itsINN Tooltip International Nonproprietary Name .[ 3] It is also known by its developmental code nameR-2453 orRU-2453 .[ 3]
Demegestone was marketed under the brand name Lutionex.[ 3] [ 4]
Demegestone is no longer marketed and hence is no longer available in any country.[ 5] It was previously available inFrance .[ 5] [ 4]
