Ultra low dose contraceptive

Anne H Calhoun
Unnecessary confusion still surrounds the use of combined hormonal contraceptives (CHCs) in the setting of migraine with aura (MwA). Clearing this confusion is a key issue for headache specialists, since most women with migraine have menstrual-related migraine (MRM), and some CHCs can prevent this particularly severe migraine. Their use, however, is still restricted by current guidelines due to concerns of increased stroke risk - concerns that originated over half a century ago in the era of high dose contraceptives...

OBJECTIVES: Safe and effective contraceptive options for obese women are becoming more important due to the obesity epidemic within the United States. This study evaluated the impact of body mass index (BMI) on efficacy, safety and bleeding patterns during use of an ultra-low-dose combined oral contraceptive (COC). STUDY DESIGN: Data are from a Phase 3 clinical efficacy and safety study of an ultra-low-dose COC containing 1.0-mg norethindrone acetate and 10-mcg ethinyl estradiol...

STUDY QUESTION: What is the efficacy of maintaining or restoring non-pregnant status with low-dose mifepristone combined with misoprostol administered before expected menstruation? SUMMARY ANSWER: Low-dose mifepristone and misoprostol administered at the time of expected menstruation was effective and safe in maintaining or restoring non-pregnant status, with no obvious menstrual disturbance. WHAT IS KNOWN ALREADY: Menstrual regulation involves the medical or mechanical stimulation of uterine sloughing in women with up to 2-3 weeks of menstrual delay...

Progestin/estrogen oral contraceptives have some side effects, including venous thromboembolism. To alleviate side effects, improvements have been made to low-dose oral contraceptives, including reductions in the amount of estrogen and/or changes the type of progestin. A compound drug containing 3mg drospirenone and 20μg ethinylestradiol (DRSP/EE20, YAZ®) was released in overseas markets in 2006, and in Japan in 2010 as a newly developed low-dose medicines. This drug is expected to have lower side effects...

OBJECTIVE: To assess the efficacy, safety, and tolerability of an extended-duration, combined hormonal oral contraceptive pill (OCP) that reduces the estrogen exposure by almost half compared with other OCPs. METHODS: This open-label, uncontrolled, multicenter study used an ultra low-dose OCP (1.0 mg norethindrone acetate and 10 micrograms ethinyl E2). The OCP was administered in a regimen of 24 days of a 28-day cycle followed by 10 micrograms ethinyl E2 for 2 days and an inactive tablet for 2 days...

UNLABELLED: The synthetic psychostimulant MDMA (± 3,4-methylenedioxymethamphetamine, ecstasy) acts as an indirect serotonin, dopamine, and norepinephrine agonist and as a mechanism-based inhibitor of the cytochrome P-450 2D6 (CYP2D6). It has been suggested that women are more sensitive to MDMA effects than men but no clinical experimental studies have satisfactorily evaluated the factors contributing to such observations. There are no studies evaluating the influence of genetic polymorphism on the pharmacokinetics (CYP2D6; catechol-O-methyltransferase, COMT) and pharmacological effects of MDMA (serotonin transporter, 5-HTT; COMT)...

Sex hormones play a key role in bone homeostasis, and oral contraceptive (OC) use may affect bone mass in women. However, the nature of the association between OC use and bone remains controversial. This paper critically reviews studies on OC use and bone published between January 2009 and August 2010. Studies of OC use and bone mass mainly focus on adolescents or young adults and showed mixed results. Weak evidence suggests that OC use has no effect or a beneficial effect on bone mass, except in women commencing OCs shortly after menarche, and a consistently negative effect on bone turnover markers...

OBJECTIVES: Guidelines recommend using the lowest effective dose of oestrogen for the management of vasomotor symptoms in postmenopausal women. The primary aim of this double-blind, multi-centre, randomised study was to assess the efficacy of oral ultra-low dose continuous combined hormone replacement therapy with 17β-oestradiol and dydrogesterone. STUDY DESIGN: 313 women with ≥50 moderate to severe hot flushes during the previous week were randomised to 0.5 mg 17β-oestradiol/2...

OBJECTIVES: To compare the effect of a low-dose oral contraceptive (OC) containing 30 microg ethinyloestradiol (EE) with that of an ultra-low-dose OC containing 15 microg EE on bone turnover and BMD in healthy adolescent women and, in addition, to ascertain the influence of body mass index (BMI) and exercise on these indices of bone metabolism. METHODS: We recruited to the study 92 healthy girls aged between 16 and 19. They were divided into three groups. Participants in the first two groups used an OC with either 15 or 30 microg ethinyloestradiol (EE), whereas those in the third group used no hormonal contraception...

Since the correlation between the amount of Ethinylestradiol (EE) and the thromboembolic risk has been recognized, the development of new oral contraceptives (OC) has been characterized by a constant lowering of the EE dosage. The consecutive decrease of ovulation inhibition has been compensated by the introduction of potent progestagens. Therefore, the contraceptive safety has been maintained in presence of less side-effects. The effect of ultra-low-dose OC on acne and seborrhea remains beneficial. The effect of ultra-low-dose OC on bone is contradictory...

OBJECTIVE: To evaluate the effect of two ultra-low-dose hormone treatments containing estradiol (E2) 0.5 mg and norethisterone acetate (NETA) 0.1 or 0.25 mg on the endometrium and bleeding. METHODS: A prospective, randomized, placebo-controlled trial of 6 months. Local Ethics Committee approval and informed consent were obtained prior to initiation and enrollment. Out of 577 postmenopausal women randomized, 575 took E2/NETA 0.1 (n = 194), or E2/NETA 0.25 (n = 181) or placebo (n = 200)...

OBJECTIVES: The aim of the present study was to evaluate the effects of low doses of hormone replacement therapy (HRT) in normal young postmenopausal women. METHODS: In an open trial healthy, non-obese postmenopausal women received for 2 years a low-dose continuous combined HRT (LD-HRT) containing 1mg estradiol+0.5 mg norethisterone acetate each pill for 28 days, or 0.5 mg of 17beta-estradiol and 0.25 mg of norethisterone acetate (Ultra low dose, Ultra-LD-HRT) along with 1000 mg of calcium per day...

OBJECTIVE: To evaluate the efficacy of two ultra-low-dose 17beta-estradiol plus norethisterone acetate (NETA) treatment regimens for relieving menopausal symptoms. DESIGN: A total of 577 postmenopausal women were enrolled, in three treatment groups in a double-blind, randomized, placebo-controlled study of 0.5 mg 17beta-estradiol + 0.1 mg NETA or 0.5 mg 17beta-estradiol + 0.25 mg NETA or placebo. Participants returned at weeks 4, 8, 12 and 24 for climacteric complaint evaluation based on a daily diary vasomotor symptom record...

OBJECTIVE: A prospective, open-label, noncomparative, multicenter study was carried out in 163 women aged 18-39 (mean 25+/-5 years), who used an ultra-low-dose oral contraceptive pill (OCP) containing gestodene (GTD) 60 mug/ethinylestradiol (EE) 15 mug for 6 months. The objective of the study was to evaluate the acceptability, safety, bleeding patterns and premenstrual symptomatology in these women. METHODS: Patients used the OCP from Days 1-24, followed by a 4-day pill-free interval from Days 25-28 of the menstrual cycle...

PURPOSE OF REVIEW: This report critically reviews recent original research articles that pertain to bone mineral density in young adult women utilizing injectable depot medroxyprogesterone acetate or oral contraceptives. RECENT FINDINGS: Some evidence indicates that depot medroxyprogesterone acetate and ultra-low dose oral contraceptives (containing 20 microg ethinyl estradiol) may interfere with the large increases normally observed in adolescence; however, the same degree of bone loss (or lack of bone gain) associated with these drugs is not so impressive in young adult women who would typically be experiencing small changes in bone mass...

Several new contraceptives have become available to women in recent years. These new agents include ultra-low-dose oral contraceptives as well as injectable, vaginal, and patch formulations. We review these, with emphasis on the Yasmin pill (which contains a new progestin), the Lunelle once-a-month injection, the Ortho Evra patch, the NuvaRing vaginal ring, the Mirena intrauterine device, and emergency contraceptive kits. Patient education regarding these options is essential for patient compliance and satisfaction...
