- Background
Desogestrel, a prodrug, is a third generation progestogen1 and hence, a member of the gonane family which was largely used in Europe before being approved in the US and Canada.4 It was firstly generated from a study that showed that 11-beta and 11-alkylidene substituent in nortestosterone can enhance the biological activity.10 Desogestrel is now produced semi-synthetically from naturally occurred plant steroids.14 In the US, desogestrel is found only in combination with ethinyl estradiol.5 The first approved drug containing desogestrel was developed by Organon USA Inc in 1972 and FDA approved in 1992.11

Pharmacology
- Indication
Oral desogestrel is used in combination with ethinylestradiol as a contraceptive agent for the prevention of pregnancy.Label
Desogestrel is part of the combined oral contraceptives that contain a mix of estrogen and progestin which inhibit ovulation.12

- Pharmacodynamics
The effects of desogestrel are divided on reproductive including modification of luteinizing hormone and follicle stimulating hormone, declines on the onset of menstruation, and increases the viscosity of the vaginal fluid; and on metabolic that includes increase insulin secretion and resistance, increased lipase activity, and increased fat deposition.9 The effect of desogestrel on the lipids has been studied extensively and the results are contradictory.
Desogestrel main therapeutic effect due to its mechanism of action is known to be related to the inhibition of the ovulation in 97% of the cycles. This effect was proven in clinical trials in non-breastfeeding women from which the Pearl failure rate was reported to be of 0.17 per 100 women-years. This result indicated that desogestrel is more efficient when compared to other progestogen-only pills.6 All the therapeutic effect is produced by a transformation of the endometrium followed by an inhibition of the ovulation due to the suppression of other hormones.10
Desogestrel has been widely confirmed to be related to an increase in the risk of venous thromboembolism due to the driven increased in blood coagulation factors, leading to a pronounced prothrombotic state.1 However, the effects of desogestrel are known to not impact significantly the level of total cholesterol remaining in the range of change of 10% which allows it to be a molecule that presents a favorable lipid profile.4
- Mechanism of action
Desogestrel enters the cell passively and acts by binding selectively to the progesterone receptor and generating low androgenic activity.8 Its binding produces an effect like a transcription factor and thus, it produces modifications in the mRNA synthesis.9
The active metabolite of desogestrel, etonogestrel, presents a combination of high progestational activity with minimal intrinsic androgenicity.Label
Target Actions Organism AProgesterone receptor agonistHumans AEstrogen receptor agonistHumans - Absorption
After oral administration, desogestrel is rapidly absorbed and it reaches a peak concentration of 2 ng/ml after 1.5 hours. The bioavailability of desogestrel is reported to be in the range of 60-80% and the reported AUC is of 3000 ng.h/ml.14 Almost all the administered dose is modified to the active metabolite, etonogestrel.7
- Volume of distribution
The apparent volume of distribution of desogestrel is of 1.5 L/kg.14
- Protein binding
The main metabolite of desogestrel is mainly found bound to albumin and sex-hormone binding globulin. Around 96-98% of the administered dose of desogestrel is found bound to plasma proteins from which 40-70% is found bound to sex-hormone binding globulin.14
- Metabolism
Desogestrel is rapidly metabolized in the intestinal mucosa and by first-pass hepatic metabolism8 to form the major metabolite of desogestrel is etonogestrel which is the biologically active metabolite.2,3 This modification is described by the hydroxylation in C3 of the desogestrel molecule.7 Later, etonogestrel is metabolized following the normal pathways of steroid metabolism. On the other hand, due to the 11-methylene side chain, desogestrel cannot be metabolized to other progestins.14

- Route of elimination
The elimination of desogestrel is found to be mainly renal corresponding to about 6 times the dose eliminated in the bile.14 The elimination of desogestrel is only done as the metabolites and not as the unchanged drug and about 85% of the administered dose can be excreted as metabolites after 6-8 days.10
- Half-life
The terminal half-life of desogestrel is determined to be of 30 hours.14
- Clearance
The metabolic clearance rate of desogestrel is reported to be of about 2 ml/min/kg.14

- Toxicity
Administration of large quantities of desogestrel has been shown to produce strong hormonal effects but to lack chronic toxicity. The reported LD50 in rats after oral administration of desogestrel is higher than 2000 mg/kg.10 Overdose hasn't reported serious effects but only symptoms of nausea and withdrawal of bleeding.Label
Most reports haven't linked the administration of desogestrel with the increased risk of breast cancer. The increased risk has been reported to be related to the duration of use. However, several reports indicate a desogestrel-driven increased risk in cervical intra-epithelial neoplasia but the results are still not conclusive.Label

- Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Ligand-dependent nuclear transactivation involves either direct homodimer binding to a palindromic estrogen response element (ERE) sequence or association with other DNA-binding transcription factors, such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3, to mediate ERE-independent signaling. Ligand binding induces a conformational change allowing subsequent or combinatorial association with multiprotein coactivator complexes through LXXLL motifs of their respective components. Mutual transrepression occurs between the estrogen receptor (ER) and NF-kappa-B in a cell-type specific manner. Decreases NF-kappa-B DNA-binding activity and inhibits NF-kappa-B-mediated transcription from the IL6 promoter and displace RELA/p65 and associated coregulators from the promoter. Recruited to the NF-kappa-B response element of the CCL2 and IL8 promoters and can displace CREBBP. Present with NF-kappa-B components RELA/p65 and NFKB1/p50 on ERE sequences. Can also act synergistically with NF-kappa-B to activate transcription involving respective recruitment adjacent response elements; the function involves CREBBP. Can activate the transcriptional activity of TFF1. Also mediates membrane-initiated estrogen signaling involving various kinase cascades. Essential for MTA1-mediated transcriptional regulation of BRCA1 and BCAS3 (PubMed:17922032). Maintains neuronal survival in response to ischemic reperfusion injury when in the presence of circulating estradiol (17-beta-estradiol/E2) (By similarity)

Exhibits high catalytic activity for the formation of hydroxyestrogens from estrone (E1) and 17beta-estradiol (E2), namely 2-hydroxy E1 and E2, as well as D-ring hydroxylated E1 and E2 at the C-16 position (PubMed:11555828, PubMed:12865317, PubMed:14559847). Plays a role in the metabolism of androgens, particularly in oxidative deactivation of testosterone (PubMed:15373842, PubMed:15764715, PubMed:22773874, PubMed:2732228). Metabolizes testosterone to less biologically active 2beta- and 6beta-hydroxytestosterones (PubMed:15373842, PubMed:15764715, PubMed:2732228). Contributes to the formation of hydroxycholesterols (oxysterols), particularly A-ring hydroxylated cholesterol at the C-4beta position, and side chain hydroxylated cholesterol at the C-25 position, likely contributing to cholesterol degradation and bile acid biosynthesis (PubMed:21576599). Catalyzes bisallylic hydroxylation of polyunsaturated fatty acids (PUFA) (PubMed:9435160). Catalyzes the epoxidation of double bonds of PUFA with a preference for the last double bond (PubMed:19965576). Metabolizes endocannabinoid arachidonoylethanolamide (anandamide) to 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling (PubMed:20702771). Plays a role in the metabolism of retinoids. Displays high catalytic activity for oxidation of all-trans-retinol to all-trans-retinal, a rate-limiting step for the biosynthesis of all-trans-retinoic acid (atRA) (PubMed:10681376). Further metabolizes atRA toward 4-hydroxyretinoate and may play a role in hepatic atRA clearance (PubMed:11093772). Responsible for oxidative metabolism of xenobiotics. Acts as a 2-exo-monooxygenase for plant lipid 1,8-cineole (eucalyptol) (PubMed:11159812). Metabolizes the majority of the administered drugs. Catalyzes sulfoxidation of the anthelmintics albendazole and fenbendazole (PubMed:10759686). Hydroxylates antimalarial drug quinine (PubMed:8968357). Acts as a 1,4-cineole 2-exo-monooxygenase (PubMed:11695850). Also involved in vitamin D catabolism and calcium homeostasis. Catalyzes the inactivation of the active hormone calcitriol (1-alpha,25-dihydroxyvitamin D(3)) (PubMed:29461981)

- UDP-glucuronosyltransferase (UGT) that catalyzes phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase the metabolite's water solubility, thereby facilitating excretion into either the urine or bile (PubMed:12181437, PubMed:15472229, PubMed:18004206, PubMed:18004212, PubMed:18719240, PubMed:19830808, PubMed:23288867). Essential for the elimination and detoxification of drugs, xenobiotics and endogenous compounds (PubMed:12181437, PubMed:18004206, PubMed:18004212). Catalyzes the glucuronidation of endogenous estrogen hormones such as estradiol, estrone and estriol (PubMed:15472229, PubMed:18719240, PubMed:23288867). Involved in the glucuronidation of bilirubin, a degradation product occurring in the normal catabolic pathway that breaks down heme in vertebrates (PubMed:17187418, PubMed:18004206, PubMed:19830808, PubMed:24525562). Also catalyzes the glucuronidation the isoflavones genistein, daidzein, glycitein, formononetin, biochanin A and prunetin, which are phytoestrogens with anticancer and cardiovascular properties (PubMed:18052087, PubMed:19545173).

- General Function
- Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (PubMed:19021548). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed:6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed:6234017)
