Filter by:The aim of our study is to assess the concentrations of different oral contraceptive agents in morbid obese women before and after two types of bariatric surgeries (RYGB and sleeve gastrectomy) in order to study the role of the surgery and the role of body weight on drug concentrations, and to compare these concentrations with those of normal-weight women.
The purpose of this study is to evaluate the contraceptive efficacy and safety of an oral contraceptive containing a combination of LNG 100mcg/EE 20mcg compared to LNG 150mcg/EE 30 mcg.
This study is being conducted to evaluate the impact of DR-102, a 28-day oral contraceptive compared to a standard 28-day oral contraceptive regimen on hemostatic parameters in healthy women.
The purpose of this research study is to gain a better understanding of the changes that may occur in the breast when a woman uses an oral contraceptive (birth control pill). Some research indicates that women who use birth control pills with lower amounts of estrogen (a hormone in the birth control pill) may have lower breast cell growth than women who use birth control pills with a higher amount of estrogen; this research will examine that in detail. This research will also test whether the results found in HS-07-00269 can be confirmed.
This study is being conducted to evaluate the impact of a 28-day oral contraceptive compared to two 28-day oral contraceptive regimens containing different synthetic progestins on ovarian follicular activity and hormone levels in healthy women.
This study is being conducted to evaluate the impact of a 91-day extended cycle oral contraceptive compared to two 28-day oral contraceptive regimens on hemostatic parameters in healthy women.
This clinical research study will examine whether an oral contraceptive pill taken with a monthly hormone-free interval of 4 days reduces hormone withdrawal associated symptoms compared to an oral contraceptive pill taken with a monthly hormone-free interval of 7 days after 4 cycles of treatment.
The purpose of this research study is to gain a better understanding of the changes that may occur in the breast when a woman uses an oral contraceptive (birth control pill). Some research indicates that women who use birth control pills with lower amounts of progestin (a hormone in the birth control pill) may have lower breast cell growth than women who use birth control pills with a higher amount of progestin; this research will examine that in detail.
The aim of the present study is to investigate whether women taking a new combined oral contraceptive pill (SH T00658ID, estradiol valerate/dienogest) experience fewer hormone withdrawal-associated symptoms such as pelvic pain or headache during their monthly cycle compared to a commonly used contraceptive pill (Microgynon).
The purpose of this study is to investigate the pharmacokinetic interaction between the combination of ethinylestradiol and norethindrone and TMC278 25 mg once daily. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. Furthermore the short-term safety and tolerability (how well the body tolerates the drug) of co-administration of TMC278 and ethinylestradiol and norethindrone, in healthy women, will be assessed.
