PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

This open-label, randomized study compared the pharmacokinetics of ethinylestradiol (EE) from the contraceptive

vaginal ring NuvaRing (15 µg EE/day), the transdermal patch (20 µg EE/day) and a combined oral contraceptive (COC)

containing 30 µg EE. After 2-8 weeks of synchronization by COC treatment, subjects were randomized to 21 days of

treatment with NuvaRing, patch or COC. Analysis of area under the EE concentration-versus-time curve (AUC) during

21 days of treatment showed that exposure to EE in the NuvaRing group was 3.4 times lower than in the patch group

(p < .05) and 2.1 times lower than in the pill group (p < .05). Serum EE levels of subjects showed much lower

variation with NuvaRing than with the patch or the COC. Thus, exposure to EE was significantly lower with NuvaRing

than with the patch and pill methods, demonstrating that NuvaRing is a low-estrogen-dose contraceptive method that

also results in low estrogen exposure. (PubHealth.info Document ID: CONT1T 88-06)
