Azurette - Clinical Pharmacology
Combination oral contraceptives act by suppression of gonadotropins. Although the primary mechanism of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increase the difficulty of sperm entry into the uterus) and the endometrium (which reduce the likelihood of implantation).
Receptor binding studies, as well as studies in animals, have shown that etonogestrel, the biologically active metabolite of desogestrel, combines high progestational activity with minimal intrinsic androgenicity (91, 92). The relevance of this latter finding in humans is unknown.
Desogestrel is rapidly and almost completely absorbed and converted into etonogestrel, its biologically active metabolite. Following oral administration, the relative bioavailability of desogestrel compared to a solution, as measured by serum levels of etonogestrel, is approximately 100%. Azurette (desogestrel/ethinyl estradiol and ethinyl estradiol) Tablets provide two different regimens of ethinyl estradiol; 0.02 mg in the combination tablet [white] as well as 0.01 mg in the light-blue tablet. Ethinyl estradiol is rapidly and almost completely absorbed. After a single dose of Azurette combination tablet [white], the relative bioavailability of ethinyl estradiol is approximately 93% while the relative bioavailability of the 0.01 mg tablet [light-blue] is 99%. The effect of food on the bioavailability of Azurette tablets following oral administration has not been evaluated.
The pharmacokinetics of etonogestrel and ethinyl estradiol following multiple dose administration of Azurette tablets were determined during the third cycle in 17 subjects. Plasma concentrations of etonogestrel and ethinyl estradiol reached steady state by Day 21. The AUC(0–24) for etonogestrel at steady state on Day 21 was approximately 2.2 times higher than AUC(0–24) on Day 1 of the third cycle. The pharmacokinetic parameters of etonogestrel and ethinyl estradiol during the third cycle following multiple dose administration of Azurette tablets are summarized in Table I.

Cmax – measured peak concentration
Tmax – observed time of peak concentration
t1/2 – elimination half-life, calculated by 0.693/Kelim
AUC0–24 – area under the concentration-time curve calculated by the linear trapezoidal rule (Time 0 to 24 hours)
CL/F – apparent clearance
Etonogestrel, the active metabolite of desogestrel, was found to be 99% protein bound, primarily to sex hormone-binding globulin (SHBG). Ethinyl estradiol is approximately 98.3% bound, mainly to plasma albumin. Ethinyl estradiol does not bind to SHBG, but induces SHBG synthesis. Desogestrel, in combination with ethinyl estradiol, does not counteract the estrogen-induced increase in SHBG, resulting in lower serum levels of free testosterone (96 to 99).Metabolism
Desogestrel is rapidly and completely metabolized by hydroxylation in the intestinal mucosa and on first pass through the liver to etonogestrel. Other metabolites (i.e., 3a-OH-desogestrel, 3ß-OH-desogestrel, and 3a-OH-5a-H-desogestrel) with no pharmacologic actions also have been identified and these metabolites may undergo glucuronide and sulfate conjugation.
Ethinyl estradiol is subject to a significant degree of presystemic conjugation (phase II metabolism). Ethinyl estradiol escaping gut wall conjugation undergoes phase I metabolism and hepatic conjugation (phase II metabolism). Major phase I metabolites are 2-OH-ethinyl estradiol and 2-methoxy-ethinyl estradiol. Sulfate and glucuronide conjugates of both ethinyl estradiol and phase I metabolites, which are excreted in bile, can undergo enterohepatic circulation.Excretion
Etonogestrel and ethinyl estradiol are excreted in urine, bile, and feces. At steady state, on Day 21, the elimination half-life of etonogestrel is 27.8 ± 7.2 hours and the elimination half-life of ethinyl estradiol for the combination tablet is 23.9 ± 25.5 hours. For the 0.01 mg ethinyl estradiol tablet [light-blue], the elimination half-life at steady state, Day 28, is 18.9 ± 8.3 hours.
There is no information to determine the effect of race on the pharmacokinetics of Azurette.Hepatic Insufficiency
No formal studies were conducted to evaluate the effect of hepatic disease on the disposition of Azurette.Renal Insufficiency
No formal studies were conducted to evaluate the effect of renal disease on the disposition of Azurette.Drug-Drug Interactions
Interactions between desogestrel/ethinyl estradiol and other drugs have been reported in the literature. No formal drug-drug interaction studies were conducted (see PRECAUTIONS section).
Non-contraceptive health benefits
The following non-contraceptive health benefits related to the use of oral contraceptives are supported by epidemiologic studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg of mestranol (73 to 78).
Effects on menses:• increased menstrual cycle regularity • decreased blood loss and decreased incidence of iron deficiency anemia • decreased incidence of dysmenorrhea
Effects related to inhibition of ovulation:• decreased incidence of functional ovarian cysts • decreased incidence of ectopic pregnancies
Effects from long-term use:• decreased incidence of fibroadenomas and fibrocystic disease of the breast • decreased incidence of acute pelvic inflammatory disease • decreased incidence of endometrial cancer • decreased incidence of ovarian cancer
