Effects of oral contraceptives containing ethinylestradiol with either drospirenone or levonorgestrel on various parameters associated with well-being in healthy women: a randomized, single-blind, parallel-group, multicentre study.

BACKGROUND: The combined oral contraceptive Yasmin (drospirenone 3 mg plus ethinylestradiol 30 microg [DRSP 3 mg/EE 30 microg]) has been shown to be a well tolerated and effective combination that provides high contraceptive reliability and good cycle control. Furthermore, DRSP 3 mg/EE 30 microg has been shown to have a positive effect on premenstrual symptoms and well-being/health-related quality of life, and to improve the skin condition of women with acne. To date, however, there have been relatively few studies that have compared the effects of DRSP 3 mg/EE 30 microg on the general well-being of women with those of other oral contraceptives. OBJECTIVES: To compare the impact of DRSP 3 mg/EE 30 microg with that of levonorgestrel 150 microg/EE 30 microg (LNG 150 microg/EE 30 microg; Microgynon 30) on various parameters associated with well-being in healthy female subjects. METHODS: This was a randomized, single-blind, parallel-group, multicentre study conducted using 21/7-day regimens of DRSP 3 mg/EE 30 microg and LNG 150 microg/EE 30 microg over seven cycles. Efficacy parameters included: changes in Menstrual Distress Questionnaire (MDQ) normative T scores; the proportion of subjects with acne; and menstrual symptoms. Cycle control and subjective well-being parameters were also assessed. RESULTS: Treatment with DRSP 3 mg/EE 30 microg had similar beneficial effects on symptoms of water retention and impaired concentration to LNG 150 microg/EE 30 microg, but was significantly better in alleviating negative affect symptoms during the menstrual phase (median difference in MDQ T score -3; p = 0.027; Wilcoxon rank sum test). The proportion of subjects with acne decreased from approximately 55% to approximately 45% in the DRSP 3 mg/EE 30 microg group, but remained static at approximately 60% in the LNG 150 microg/EE 30 microg group. Somatic and psychological symptoms occurred at the greatest intensity and for most subjects during the menstrual phase of the cycle in both groups. CONCLUSIONS: Both drugs had similar cycle control parameters with a tendency towards reduced bleeding with continued use. More subjects in the DRSP 3 mg/EE 30 microg group reported improved physical well-being (60% vs 46%; p = 0.035; chi-squared [chi2] test). Emotional well-being was reported improved in 61% and 51% of DRSP 3 mg/EE 30 microg and LNG 150 microg/EE 30 microg users, respectively (p = 0.1190; chi2 test). Adverse events were typical of oral contraceptive use and did not give rise to any safety concerns. Both products had similar beneficial effects on symptoms of water retention and impaired concentration, but DRSP 3 mg/EE 30 microg was significantly better in alleviating negative affect symptoms during the menstrual phase. The proportion of subjects with acne decreased in the DRSP 3 mg/EE 30 microg group but not in the LNG 150 microg/EE 30 microg group. More subjects in the DRSP 3 mg/EE 30 microg group reported improved physical well-being compared with the LNG 150 microg/EE 30 microg group.

Selective serotonin re-uptake inhibitor treatment-emergent sexual dysfunction: randomized double-blind placebo-controlled parallel-group fixed-dose study of a potential adjuvant compound, VML-670.

Sexual dysfunction is common during acute and continuation treatment of depressed patients with selective serotonin (5-hydroxytryptamine, 5-HT) re-uptake inhibitors (ssRIs), but there is no consensus on clinical management. Compounds with 5-HT(1A) agonist properties have been proposed as adjuvant agents in patients continuing with ssRIs. Randomized double-blind placebo-controlled parallel-group fixed-dose 4-week treatment study. Previously depressed male or female patients in symptomatic remission receiving stable doses of fluoxetine or paroxetine but experiencing treatment-emergent sexual dysfunction were randomised to double-blind treatment with placebo or VML-670 (a 5-HT(1A) and 5-HT(1D) agonist). sexual dysfunction was assessed by the Arizona sexual Experiences scale (ASEX). Two-hundred and eighty-eight patients (204 women, 84 men; mean age 44.2 years) received VML-670 (n = 149; 107 women, 42 men) or placebo (n = 139; 97 women, 42 men). In the intention-to-treat, last-observation carried forward analysis (n = 282), proportionately more patients became free of sexual dysfunction with VML-670 (34.3% versus 27.9% with placebo) but this difference was not statistically significant. Male patients treated with VML-670 showed a significantly greater (p =0.01) improvement in ability to achieve and maintain penile erection (a secondary outcome measure). A similar proportion of patients reported on-treatment, treatment-emergent adverse events with VML-670 (71.1%) and placebo (68.3%), and a similar proportion experienced at least one treatment-related adverse event (36.9% versus 35.3%). Double-blind treatment with VML-670 offered no significant advantage over placebo on the primary outcome measure in the overall sample. Further studies may be warranted in larger groups of male patients with sexual dysfunction.
