tri-cyclen and Acne-Vulgaris

Oral contraceptives (OCs) have been shown to effectively treat acne. Clinical trials of various doses of ethinyl estradiol (EE) combined with progestins such as levonorgestrel, desogestrel, norgestimate, gestodene, cyproterone acetate and drospirenone in monophasic, triphasic and combiphasic formulations used to treat acne in women are reviewed here. Open-label and comparative studies beginning in the 1980s were the first to demonstrate objective and subjective reductions in the incidence of acne, severity of existing acne and seborrhea. Placebo-controlled trials have corroborated these findings with a trend toward effective acne treatment with declining doses of EE. Significant reductions in total, inflammatory and noninflammatory lesions compared with placebo have been demonstrated with an OC containing the low dose of 20 microg of EE. Collectively, these findings support the use of low-dose OCs for the treatment of acne.

Sexual activity is quite common among women aged 14 to 20 in developed countries, averaging perhaps 10% at age 15 to about 70% at 19. Thus, the need for contraception may begin quite early in life and will continue for as long as 30 years. One of the best candidates for long-term contraception for young sexually active females is the oral contraceptive (OC), which provides health benefits besides contraception. Long-term benefits include lowered rates of ovarian and endometrial cancer, as well as of benign breast disease and ovarian cysts. Another benefit is protection against upper-tract sequelae of sexually transmitted diseases. Short-term benefits are correction of menstrual irregularity, reduction in menstrual flow, and diminished premenstrual syndrome and dysmenorrhea. Recent OC formulations contain only one-third the estrogenic potency of older OCs and therefore are associated with dramatic decreases in what were always the major side effects of OCs: heart attack, stroke, and pulmonary embolism. Other side effects of OCs have been most closely associated with the progestogenic component, and are related to the androgenic effects of progestins, particularly some synthetic progestins. However, some new synthetic progestins have been found to have minimal androgen receptor activity in preclinical testing and to cause minimal or no androgen-related side effects in clinical trials. One of these new progestins having a favorable androgenic profile is norgestimate. Its efficacy and safety in combination with low doses of ethinyl estradiol have been documented in the European and the American literature.(ABSTRACT TRUNCATED AT 250 WORDS)

This double-blind study compared the efficacy and tolerability of a combined oral contraceptive containing 30 microg ethinyl estradiol and 3 mg drospirenone (EE/DRSP; Yasmin) with a triphasic preparation containing 35 microg EE and 0.180, 0.215, 0.250 mg norgestimate (EE/NGM; Pramino, also known as Ortho Tri-Cyclen) in the treatment of acne vulgaris. The combined presence of antiandrogenic and antimineralocorticoid activities of drospirenone is unique to this novel progestin in that these characteristics most closely resemble those of progesterone. The study was designed to show that EE/DRSP was noninferior or superior to EE/NGM as to the relative decrease from baseline to cycle 6 in percentage of inflammatory and total lesion counts and the investigators' assessment of acne improvement. Other outcomes included subjects' assessment of therapeutic effect, sebum production, and hormone levels. Female subjects were randomized to EE/DRSP (n = 568) or EE/NGM (n = 586) for 6 treatment cycles, consisting of 21 consecutive days of hormone intake, followed by 7 hormone-free days. The preparation containing EE/DRSP was superior to EE/NGM for reduction in total lesion count (-3.3% in favor of EE/DRSP [95% CI, -6.5 to -0.1; P = .020]) and for investigators' assessment of therapeutic effect on facial acne (+3.6% in favor of EE/DRSP [95% CI, 0.8 to 6.3; P = .006]). The 2 preparations were comparable as to their decreases in inflammatory lesion count. Evaluation of the effect of treatment by subjects was consistent with that of the investigators. Furthermore, both preparations increased the level of sex hormone-binding globulin (SHBG) and decreased the levels of androgens, changes typically associated with acne improvement. Both preparations were well tolerated. In conclusion, owing to the unique pharmacologic activities of drospirenone, the combined oral contraceptive EE/DRSP provides an effective treatment option in female patients with mild to moderate acne.

Serum androsterone glucuronide (AoG) is a metabolite of circulating androgens under the influence of 5alpha-reductase activity and has been shown to be particularly elevated in women with acne. In this study, we wanted to evaluate changes in AoG before and after treatment with an oral contraceptive or placebo, and to assess whether changes correlated with the number and type of acne lesions. In order to accomplish these aims, we obtained sera from a completed prospective randomized trial, which was designed to assess the effectiveness of an oral contraceptive compared to placebo. Assessments were carried out in 56 women with moderate acne who were treated with Ortho Tri-Cyclen (norgestimate and ethinylestradiol) (30 patients) or placebo (26 patients) for 6 months. Before and after treatment, the number and type of skin lesions, serum levels of total T, free-T, DHEAS and AoG were determined. Serum AoG increased significantly in women with moderate acne, although T, free-T and DHEAS were normal. 75% of acne patients had elevated levels of serum AoG. Ratios of serum AoG to androgen precursors were also elevated. Oral contraceptive (OC) treatment significantly reduced levels of free-T and AoG, both of which were unaffected by placebo. While both OC and placebo treatment resulted in improvement of comedones and inflammatory lesions, OC treatment decreased inflammatory lesions to a greater extent (p<0.05). After treatment, serum AoG correlated with the number of inflammatory lesions. Results showed that serum AoG is a sensitive marker of acne in women, even in those with normal circulating precursor androgens; and is lowered by OC treatment, correlating with the reduction of inflammatory lesions. We hypothesize that the increase of serum AoG in normoandrogenic acne may be related to inflammation, and serum AoG may serve as a marker of this process.

Two multicenter, double-blind, placebo-controlled studies were conducted to evaluate the effectiveness of triphasic norgestimate/ethinyl estradiol (Ortho Tri-Cyclen) for the treatment of acne vulgaris. To our knowledge, these studies were the first double-blind, placebo-controlled trials to evaluate the efficacy of an oral contraceptive (OC) in the treatment of acne; in fact, they are probably the first placebo-controlled trials ever completed using modern OC. This article examines the conduct and feasibility of these studies including discussions on study planning enrollment, maintenance of the blind, continuation rates, and pregnancy prevention. Subjects were between the ages of 15 and 49 years, with moderate acne vulgaris, no contraindications to oral contraceptive use, and were willing to use a nonsteroidal method of birth control during the 6 months of the trial. More than 500 participants were enrolled in 1 year. Discontinuation rates between groups were similar. To explore the reasons for the similar and low discontinuation rates, OC-related side effects were evaluated in comparison to placebo. This analysis revealed that the OC exhibited a side effect profile that was similar, in many cases, to that of placebo. Although pregnancies occurred in the placebo arm, the incidence was consistent with expected failure rates for users of nonsteroidal methods in the general population.

An excess of androgen is believed to contribute to development of acne in some patients. Because oral contraceptives (OCs) may reduce the active androgen level, hormonal therapy with OCs has been used successfully to treat patients with acne, although this treatment has previously not been studied in placebo-controlled trials.. Our purpose was to evaluate the efficacy of a triphasic, combination OC (ORTHO TRI-CYCLEN [Ortho-McNeil Pharmaceutical, Raritan, N.J.], norgestimate/ethinyl estradiol) compared with placebo in the treatment of moderate acne vulgaris.. Two hundred fifty-seven healthy female subjects, 15 to 49 years of age with moderate acne vulgaris, were enrolled in a multicenter, randomized, double-blind, placebo-controlled clinical trial. Each month for 6 months, subjects received either 3 consecutive weeks of the OC (i.e., tablets containing a fixed dose of ethinyl estradiol [0.035 mg] and increasing doses of norgestimate [0.180 mg, 0.215 mg, 0.250 mg]) followed by 7 days of inactive drug or placebo (color-matched tablets). Efficacy was assessed by facial acne lesion counts, an investigator's global assessment, a subject's self-assessment, and an analysis of within-cycle variation (cycle 6) in lesion counts.. Of the 160 subjects in whom efficacy could be evaluated, the OC group showed a statistically significantly greater improvement than the placebo group for all primary efficacy measures. The mean decrease in inflammatory lesion count from baseline to cycle 6 was 11.8 (62.0%) versus 7.6 (38.6%) (p = 0.0001), and the mean decrease in total lesion count was 29.1 (53.1%) versus 14.1 (26.8%) (p = 0.0001) in the OC and placebo groups, respectively. In the investigator's global assessment, 93.7% of the active treatment group versus 65.4% of the placebo group were rated as improved at the end of the study (p < 0.001). Six of the seven secondary efficacy measures (total comedones, open comedones, closed comedones, papules, pustules, and the subject's self-assessment of study treatment) were also significantly more favorable in the OC group compared with the placebo group.. An OC containing 0.035 mg of ethinyl estradiol combined with the triphasic regimen of norgestimate is a safe and effective treatment of moderate acne vulgaris in women with no known contraindication to OC therapy.. To evaluate the efficacy of a triphasic combined oral contraceptive (OC) in the treatment of moderate acne vulgaris, 231 healthy US volunteers 15-49 years of age with this dermatologic condition were enrolled in a phase III, multicenter, double-blind, placebo-controlled clinical trial. Each month for 6 months, subjects (n = 110) received either 3 consecutive weeks of Ortho Tri-Cyclen (containing a fixed dose of 0.035 mg of ethinyl estradiol and 0.180, 0.215, and 0.250 mg of norgestimate) followed by 7 days of inactive drug or placebo. The OC group showed significantly greater improvement than controls on all efficacy measures. The mean decrease in inflammatory lesion count from baseline to the sixth cycle was 11.8 (62.0%) among cases and 7.6 (38.6%) in controls, while the mean decrease in total lesion count was 29.1 (53.1%) versus 14.1 (26.8%) in the OC and placebo groups, respectively. In the investigator's global assessment, 93.7% of women in the treatment group and 65.4% of controls were rated as improved at the end of the study. Similarly, more cases than controls considered their acne "improved" at the study's end and expressed a preference for this therapy over other forms of acne treatment. These findings indicate that treatment of moderate acne vulgaris with a low-dose triphasic OC is safe and effective in women with no contraindications to OC use.
