Chlormadinone acetate has not been used in the United States since 1970, when the only product (an oral contraceptive) was removed from the market. Its use in the United Kingdom was suspended in the same year. Before suspension, chlormadinone acetate was used in oral contraceptives either together with mestranol as a "sequential" contraceptive or as a "progestogen only" oral contraceptive. Chlormadinone acetate has been used (frequently in combination with mestranol) for treatment of threatened abortion and dysmenorrhea.

Ethinylestradiol/chlormadinone acetate 0.03/2mg (EE/CMA) is a combined monophasic contraceptive pill with anti-androgenic properties. In a large, non-comparative, multicentre trial (< or =24 cycles of treatment per woman) and two (6- and 12-cycle) post-marketing surveillance studies, EE/CMA was effective in preventing pregnancy. EE/CMA was significantly more effective than EE/levonorgestrel 0.03/0.15 mg/day in treating women with mild-to-moderate papulopustular acne of the face and related disorders in a randomized, single-blind, multicentre trial. EE/CMA was well tolerated in clinical trials and the post-marketing surveillance studies. Adverse events were those commonly reported with oral contraceptives. As expected, the most common menstrual disturbances were breakthrough bleeding, spotting and amenorrhea.

... Pharmacokinetic studies have shown rapid and almost complete absorption after oral administration, and chlormadinone acetate is being bound to albumin rather than SHBG (Sex-Hormone-Binding-Globulin). Multiple dosing studies have demonstrated that steady state is reached by day 7 after oral administration with peak plasma concentrations in the region of 2 ng/mL. ...

The half-life and metabolic clearance rate of chlormadinone acetate were computed after a single iv injection of 60 to 90 mcCi 1-alpha-tritiated-chlormadinone acetate (specific activity 222 mcCi/mg) into 7 women aged 34-52 years. Plasma was extracted with acetone:MeOH for total radioactivity; then extracted with water and ether for free steroid radioactivity; then with n-butanol for conjugated steroid radioactivity; and finally extracted with chloroform:MeOH and chromatographed on thin layer with ether:benzene for specific radioactivity due to chlormadinone acetate. Blood samples were taken at 0 .25, 0.5, 1, 8, 24 hours and every 24 hours for 5 days. ... All 4 curves, total radioactivity, conjugated steroids, free steroids, and specific activity had the same biphasic form: a rapid loss for about 24 hours, and an approaching equilibrium after 24 hours. The metabolic clearance rate was 42.61 liters per day... These data generate an estimate of the concentration of chlormadinone acetate in plasma of women taking 0.5 mg daily: about .45 ng/mL, i.e. about one-thirteenth the concentration of progesterone.

Published data on pharmacokinetic parameters for chlormadinone acetate (CMA) are in part contradictory, especially with regard to terminal half-life (t(1/2,z)). Single and multiple doses of CMA (2 mg) and ethinylestradiol (EE; 0.03 mg) were administered to healthy female volunteers for six menstrual cycles. Plasma concentrations of CMA and EE were determined by gas chromatography-mass spectrometry. Single-dose and steady-state pharmacokinetic parameters were calculated. In a separate study, healthy female volunteers were given a single 2-mg dose of radiolabeled CMA. Concentrations of radioactivity in fecal and urine samples were determined via liquid scintillation. Excretion of total radioactivity was calculated as percentage of administered dose. Eighteen women completed the repeated-dose study. Peak plasma concentrations for CMA and EE were reached within 1 and 2 hr after taking the study drug. Peak plasma concentrations of CMA were approximately 1600 pg/mL after single-dose administration and 2000 pg/mL after multiple dosing. CMA and EE showed linear pharmacokinetics throughout six cycles, with constant trough values of approximately 400-500 pg/mL for CMA and 20-40 pg/mL for EE. Mass balance factors were 1.2-1.4 for CMA and 1.6-1.7 for EE, and accumulation factors were 1.7-2 for CMA and 1.7-1.8 for EE. Mean t(1/2,z) of CMA was approximately 25 hr after single dosing and 36-39 hr at steady state. In the excretion balance study, mean dose of CMA recovered was 87.3+/-6.4%, with urinary and fecal excretion accounting for 45% and 42%, respectively. The pharmacokinetics of CMA and EE is linear after multiple dosing and remains stable during long-term administration, once steady state is reached. The t(1/2,z) of CMA was 36-39 hr after multiple dosing, which is considerably shorter than the 80 hr often quoted in the literature.

The bioavailability and bioequivalence of two different film coated tablets containing ethinylestradiol and chlormadinone acetate (Bellissima as test and the respective preparation from the originator as reference) were investigated in 20 healthy female volunteers after oral single-dose administration. The study was performed according to a single-center, randomised, single-dose, 2-way cross-over design with a wash-out phase of 28 days. Blood samples for pharmacokinetic profiling were taken up to 168 hr post-dose, and ethinylestradiol and chlormadinone acetate plasma concentrations were determined with a validated LC-MS/MS method. The observed mean maximum plasma concentrations (Cmax) of ethinylestradiol were 124.96 pg/mL (test) and 129.12 pg/mL (reference). In the case of chlormadinone acetate, Cmax averaged 6.9566 ng/mL (test) and 6.6663 ng/mL (reference). The geometric means of area under the plasma concentration-time curve (AUC(0-infinity)) of ethinylestradiol were 1292.35 pg/mL x hr (test) and 1380.49 pg/mL x hr (reference). For chlormadinone acetate, geometric means of AUC(0-infinity) were 53.322 ng/mL x hr (test) and 58.111 ng/mL x hr (reference). The median of tmax of ethinylestradiol was 1.5 hr for both test and reference and the median of tmax of chlormadinone acetate 1.0 hr (test) and 1.5 hr (reference). Plasma elimination half-lives (t1/2) of ethinylestradiol were 14.96 hr (test) and 15.41 hr (reference) and of chlormadinone acetate 56.63 hr (test) and 56.17 hr (reference), respectively. Both primary target parameters AUC(0-infinity) and Cmax were tested parametrically by analysis of variance (ANOVA). The point estimator and the 90% confidence intervals for the AUC(0-infinity) ratio (test/reference: 93.72% [86.62%-101.39%]) indicate high similarity of both formulations with respect to the extent of ethinylestradiol exposure. A high degree of similarity was also observed for Cmax of ethinylestradiol, as the point estimator and the 90% confidence interval for the Cmax ratio are 96.18% (90.82%-101.86%). Regarding the AUC(0-infinity) ratio of chlormadinone acetate, the point estimator is 91.60% and the 90% confidence interval 84.08%-99.79%. Furthermore, exchangeability of both formulations is also suggested by the point estimator and 90% confidence of Cmax of this active agent (104.72% [95.76%-114.53%]). Bioequivalence between test and reference formulation was demonstrated since for both ethinylestradiol and chlormadinone acetate all 90% confidence intervals of AUC(0-infinity) and Cmax fall into the generally accepted range of 80%-125%.

After intravenous injection of radiolabelled chlormadinone acetate, the steroid and its metabolites have an initial rapid half-life of 2.4 hours, followed by a slow half-life of 80.1 hours. The mean metabolic clearance rate is 126 L/day for chlormadinone acetate and 42.6 L/day for chlormadinone acetate and its metabolites. The long half-life and slow elimination rate are probably due to accumulation of the drug in fat tissue.

The major metabolites of chlormadinone acetate are 2alpha- hydroxychlormadinone acetate and 3beta-hydroxychlormadinone acetate. Incubation of chlormadinone acetate with human or rat liver microsomes produces mainly the 3beta-hydroxy metabolite. In contrast, incubation with microsomes from phenobarbital-treated rats produces the 2alpha-hydroxy metabolite, indicating that the metabolite pattern is dependent on the hepatic monoxygenase state.

Chlormadinone acetate (CMA) is a derivative of naturally secreted progesterone that shows high affinity and activity at the progesterone receptor. It has an anti-estrogenic effect and, in contrast to natural progesterone, shows moderate anti-androgenic properties. CMA acts by blocking androgen receptors in target organs and by reducing the activity of skin 5alpha-reductase. It suppresses gonadotropin secretion and thereby reduces ovarian and adrenal androgen production. CMA shows high contraceptive efficacy by inhibiting ovulation due to its ability to suppress or disrupt endogenous gonadotropin secretion and, by this, inhibits follicular growth and maturation. In addition, it suppresses endometrial thickness and increases the viscosity of cervical mucus. ...

The ovulation response to electrical stimulation of the median eminence, or to the intrapituitary infusion of median eminence extract, was observed in control rabbits and animals pre-treated with chlormadinone acetate. Chlormadinone acetate pre-treatment did not significantly reduce the proportion of rabbits ovulating in response to electrical stimulation. However, there was a significant reduction in the average number of ruptured follicles when compared with the animals in the control group. Chlormadinone acetate pre-treatment significantly reduced the proportion of animals ovulating in response to the intrapituitary infusion of median eminence extract as compared with the control series. However, there was no significant reduction in the average number of ruptured follicles (in those rabbits that ovulated) when compared with the control groups. Chlormadinone acetate pre-treatment produced no significant effect upon either the proportion of animals ovulating, or the average number of ruptured follicles, following i.v. injection of 50 ug LH.5. The conclusion drawn is that chlormadinone acetate blocks copulattion-induced ovulation in the rabbit by action at a site in the central nervous system located above the median eminence. The possible effects of chlormadinone acetate upon the secretion of FSH, the pituitary sensitivity to releasing factors and the ovarian sensitivity to LH are discussed.

Studies with the human breast cancer cell line ZR-75-1, which contains functional estrogen, progesterone and androgen receptors, suggest that chlormadinone acetate inhibited the growth of these cells by an interaction of androgen and progesterone receptor-mediated mechanisms.

Groups of 8-12 male Sprague-Dawley Crl:CD(SD)Br rats were castrated and injected immediately thereafter twice daily for 14 days with one of a number of synthetic progestogens, including chlormadinone acetate, used in the treatment of prostate cancer. Controls received the vehicle, 1% gelatine in 0.9% saline... Dihydrotestosterone was injected at a dose of 150 ug twice daily for 14 days as a positive control. All animals were killed on the morning after the last day of treatment, and the ventral prostate and adrenals were removed and weighted; furthermore, the prostatic content of ornithine decarboxylase was measured, as it is consider to be a highly specific, sensitive of androgenic activity in the prostate. Dihydrotestosterone increased the ventral prostate weight to 43% above that of castrated controls. Chlormadinone acetate was less potent than dihydrotestosterone but caused significant increases in prostate weight, by about 22% at 3 mg and 36% at 10 mg per injection. Whereas dihydrotestosterone caused a 14-fold increase in ornithine decarboxylase activity in the prostate, chlormadinone acetate caused a 5.3-fold increase at 3 mg and an 11.8-fold increase at 10 mg. Chlormadinone acetate thus has weak but significant androgenic activity in the rat ventral prostate.
