Study summary

The purpose of this study is to evaluate different side effect in contraceptive use of two oral combined contraceptive pills (OCP)in combination of 30 mcg ethinylestradiol/2 mg chlormadinone acetate (Belara®) and 30 mcg ethinylestradiol/3 mg drospirenone (Yasmin®), especially body weight change.

Read the detailed description

Oral combined contraceptive pills (OCP) is the most contraceptive use in reproductive women. The various type of progestins in OCP give various effects either benefit (non-contraceptive benefit) and side effect. These effects depend on pharmacological activity of each progestin. Many studies showed causes of discontinuation use of OCP, such as increase body weight,androgenic effect and vaginal spotting. OCP in combination of 30 mcg ethinylestradiol/2 mg chlormadinone acetate (Belara®) and 30 mcg ethinylestradiol/3 mg drospirenone (Yasmin®)are the common used in practice. The each type of progestin (chlormadinone and drospirenone) might effect different outcomes in women especially in body weight change during use. Chlormadinone is a C-21 progestin which has glucocorticoid and antiandrogenic effect. Drospirenone is a progestin in spironolactone derivative which has antimineralocorticoid and antiandrogenic effect. Both progestins might has less effect in body weight change and provide other non-contraceptive benefits. So investigator want to study the different effects from these progestin in two type of OCP. The result from this study could give information to choose the proper OCP for each reproductive woman.

What researchers measure

Primary outcomes

  1. body weight change

    Compare the body weight change during use of two OCP (30 mcg ethinylestradiol/2 mg chlormadinone acetate (Belara®) and 30 mcg ethinylestradiol/3 mg drospirenone (Yasmin®)). By follow up at 3rd and final at 6th month of use.

    Time frame: 6 month

Secondary outcomes

  1. efficacy in contraception (pregnancy rate)

    To evaluate contraceptive efficacy of two OCP. Urine pregnancy test was used to evaluate pregnancy, the participant was tested in every visit of the study.

    Time frame: 6 month

  2. Other side effects

    To evaluate other side effects during using both OCP,such as vaginal spotting, androgenic effect, blood pressure, headache and GI effect. Vaginal spotting was classified by number of pad (WHO definition) which the participant used in each cycle and record in menstrual card. Androgenic effect was classified by Modified Ferriman - Gallway Score for hirsutism (score \> 7), American Academy of Dermatology Consensus 2009 on acne classification (mild, moderate, severe)for acne, systolic/diastolic blood pressure and the presence or no presence of headache and GI discomfort.

    Time frame: 6 month

  3. satisfaction

    To compare satisfaction in study process. In each visit (first, 3rd month and 6th month of study period). The participant was evaluated satisfaction in topics of diagnosis, timing of study process, information from the staff about the study process and the way to use oral pills, quality of the oral pills and conclusive satisfaction. The rating of satisfaction was categorised in five levels as five scoring numbers by using questionnaire; 5=extreme satisfaction, 4=very satisfaction, 3=moderate satisfaction, 2= little satisfaction, 1=no satisfaction.

    Time frame: 6 month

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 9, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
