Now triphasic contraceptive preparations are used widely. Some news low dose formulations are available on the market, among them Trisiston. The study was conducted to confirm clinically acceptance and effectiveness of Trisiston. There were 437 volunteers mostly multiparous, with a mean age of +/- 25 years who participated in a multi center study. They were taking pills for a 3 to 12 cycles. Cumulatively 4026 cycles were observed. The investigation was conducted according special protocol. At the admission a complete medical history was obtained and a general physical and gynecological examination was performed. All subject were controlled every 3rd month included laboratory tests (blood levels of Hb, WBC, RBC, ESR, carbohydrate metabolism, clotting factors, bilirubin, creatinine, protein, glucose, albumin, LDL, HDL). There was no case of pregnancy. Pearl index = 0. The Trisiston was well tolerated by most of women (80%). Some effects like headache, vertigo, mastalgia, spotting and breakthrough bleeding, loss of libido, premenstrual syndrome were observed in 20% patients, soma of our patients (20%) discontinued contraceptive.

Research in the area of oral contraception currently focuses on the development of selective progestogens that combine targeted progestational and antiovulatory activity with a minimal potential for androgenicity. The present dual-center study was conducted to investigate the efficacy, tolerability, and safety of a new monophasic oral contraceptive (OC) containing 250 micrograms norgestimate in combination with 35 micrograms ethinyl estradiol (Ortho-Cyclen or Cilest). Ninety-seven healthy women of childbearing age participated in the study: 37 received the new norgestimate/ethinyl estradiol combination OC as primary therapy and 31 were switched over from other OCs. The norgestimate/ethinyl estradiol formulation was well tolerated and was associated with excellent cycle control. After six cycles of use, there were no statistically significant differences in the incidence of spotting or breakthrough bleeding compared with baseline, nor were there any significant changes in the incidence of headache, nausea, or mastalgia. Body weights remained constant for the duration of the study, as did systolic and diastolic blood pressures. Of particular note was the absence of any statistically significant alterations in metabolic parameters, including blood glucose or lipoprotein levels. These findings are consistent with the results of several other European studies and indicate that the norgestimate/ethinyl estradiol combination OC combines superior cycle control with minimal risk of androgenic side effects.

The Norplant implant is described: the release rates and serum levels of levonorgestrel, the mode of action, the indications and contraindications, the effectiveness, incidence of ectopic pregnancy related to Norplant use, metabolic effects, advantages and disadvantages, insertion, the role of counseling, and management of side effects (menstrual bleeding changes, headache, weight changes, mastalgia, and acne), continuation rates and reasons for termination, and removal. Norplant is currently the most effective method of contraception. Counseling is important in order to provide women with as much information for informed consent and to increase awareness and interest in Norplant. In a clinical trial in California, 95% expressed a high level of satisfaction upon implant removal and 71% desired Norplant again; 91% recommended Norplant to friends. 82% reported the side effect of menstrual change; 66% reported 2 or more side effects. Clinical development is ongoing for other sustained release contraceptives. Norplant was developed by the International Committee for Contraceptive Research of the Population Council, and manufactured by Huhtamaki Oy/Leiras Pharmaceuticals in Turku, Finland. Clinical trials have been conducted since 1975. 20 nations have approved its use, and more than 1.5 million women use it. Silastic rubber tubing encapsulates 6 capsules of 36 mg/capsule crystalline levonorgestrel, a strong progestin. Implantation is done just under the skin in a fan shape; levonorgestrel is released at 80 mcg/day for 6 months, and 30-35 mcg/day for the remainder of use. The mode of action is not completely understood, but the assumption is that it is similar to the progestin-only pills. The mechanisms that alter fertility are 1) the change in hypothalamic-pituitary level to inhibit midcycle luteinizing hormone surge, while follicle stimulating hormone and estradiol levels remain within the normal range, 2) the thickening of the cervical mucus which prevents the entry of sperm into the upper genital tract, and 3) the suppression of the estrogen-induced cyclical maturation of the endometrium. It is not an abortifacient. Contraindications are few, but include active thrombophlebitis, undiagnosed abnormal genital bleeding, known or suspected pregnancy, benign or malignant liver tumors, and known or suspected breast cancer of progestin-dependent neoplasms.

The present dual-center study was conducted to investigate the efficacy, tolerability, and safety of a new monophasic oral contraceptive (OC) which contains 250 mcg norgestimate in combination with 35 mcg ethinyl estradiol (EE; Ortho-Cyclen or Cilest). 97 healthy women of childbearing age were part of this study; 37 received the new norgestimate/EE combination OC as primary therapy and 31 were switched over from the other OCs. The formulation was well-tolerated and was associated with excellent cycle control. After 6 cycles of use, there was no statistically significant difference in the incidence of spotting or breakthrough bleeding as compared with the baseline. Nor were there any significant changes in the incidence of headache, nausea, or mastalgia. Body weights remained constant for the duration of the study as did systolic and diastolic blood pressures.

A comparison of the triphasic Triphasil and the combined oral contraceptive Diane 50 for treatment of acne for 6 cycles showed significant improvement in both groups. Triphasil (Wyeth-Ayerst) contains 50 mcg levonorgestrel and 30 mcg ethinyl estradiol, 75 mcg levonorgestrel and 40 mcg ethinyl estradiol for 5 days and 125 mcg levonorgestrel and 30 mcg ethinyl estradiol for 10 days. Diane 50 (Schering Ag) contains 2 mg cyproterone acetate and 50 mcg ethinyl estradiol for 21 days per cycle. 10 women in each group had physical, pelvic, ophthalmologic and neurologic exams, hematologic and biochemical screens, assays of free testosterone, sex hormone binding globulin (SHBG), androstenedione, dehydroepiandrosterone SO4 (DHEAS), progesterone, and computations of acne and hirsutism scores. Subjects had used tetracyclines, isotretinoin, erythromycin, topical clindamycin and benzoyl peroxide previously, but were withdrawn from medication in the cycle before the intervention. The mean acne scores, derived from grading and counting lesions and comedones, fell from 63.3 to 6 in the Diane 50 and from 64.2 to 4.5 in the Triphasil group. Subjective results were excellent for 6, good for 2 and unsatisfactory for 2 in the Diane 50 group, and excellent for 8 and good for 2 in the Triphasil group. In both groups mean free testosterone, androgen index, androstenedione and DHEAS, and an increase in SHBG were documented. 5 Triphasil and 5 Diane 50 subjects had increased cholesterol levels during the trial, the only abnormality detected. Side effects reported were recurrence of varicose veins and hemorrhoids in 1 women who withdrew, and complaints of mastalgia, nausea, dysmenorrhea, migraine, headache, backache and vaginal discharge.

PMS is probably a group of entities which include various symptoms that occur during the 7 to 10 days before menstruation and disappear a few hours after the onset of menstruation. The definition of PMS lacks objective criteria. The most common symptoms are irritability, bloating, aggressiveness, mastodynia, and headaches. The prevalence of PMS is estimated at 30 to 40 per cent. PMS is more prevalent among women working outside the home, alcoholics, women of high parity, and women with toxemic tendency; it probably runs in families. The etiology of PMS is no less obscure to us than when it was first described by Frank in 1931. No single theory has been established to explain the entire diversity of PMS symptomatology. The multitude of possible etiologic factors includes psychosocial bases, progesterone deficiency, prolactin excess, thyroid hypofunction, renin angiotensin alternations, antidiuretic hormone excess, decreased colloidosmotic pressure, endorphin activity alternations, serotonin metabolism alternations, prostaglandin action, vitamin deficiency, and such unconventional theories as the ovarian infection or the "yeast overgrowth" theory. A partial resolution of this divergence of hypotheses comes from the biopsychosocial model developed by Keye and Trunnel. According to this model, a biologic, perhaps genetically determined, predisposition to PMS is realized when past and present life experiences, attitudes, beliefs, coping styles, and social forces interact to stress a woman. The diagnosis of PMS is based on establishing a relationship between the luteal phase of the cycle and the symptoms. The evaluation of PMS patients includes the use of a monthly diary to scale the symptoms, a physical examination, and biochemical studies to rule out other disorders. Management includes education, reassurance, and drug therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

During a 5 year period 62 patients requesting post coital contraception were give 2 doses of 200 mg danazol for 5 days after being informed of possible side effects and about the lack of experimental data on its effectiveness. All patients were advised to make notes about side effects, spotting, and the nature, quantity, and duration of menstrual flow, 35 of the women were nulliparae and 27 pluriparae aged 16 to 42, 52 had had unprotected sexual activity and 10 rupture of the condom that motivated them to seek contraception. Nausea occurred in 18, headache in 3, and mastodynia in 5 cases. 57 patients reported regular, 2 early, and 3 late menstruation. Hypomenorrhea occurred in 3 and menorrhagia in 9 cases. The administration of danazol took place between the 11th and 15th day of the menstrual cycle, but it proved ineffective in 1 case when the drug was given on the 20th day, however, this may have been attributable to previous unprotected sex. Danazol proved to be a good post-coital contraceptive with a high rate of efficacy and good tolerability. Treatment exceeding 5 days produced only a minor emotional tension in 4 patients.

Medroxyprogesterone acetate injections (Depo-Provera) were given to 625 women at 3 monthly intervals involving 693 episodes. Ages at entry to the study ranged from 15-51 years with the majority in their 20s and a mean age of 30. Length of exposure ranged from 3-168 cycles. 4 women have received more than 160 continuous cycles of DMPA. Of the medication-induced reasons for discontinuing DMPA, bleeding was the most common with an incidence of 10.5% followed by depression (1.4%), weight gain (1.4%), and loss of libido (1.6%). No patient ceased treatment because of headaches, recurrent vaginal infections, mastalgia, nausea, chloasma, hypertension, or other vascular illnesses. The 59 women who move away or were lost to follow-up accounted for 405 cycles of treatment. The solitary unplanned pregnancy occurred in a 28-year-old obese woman who had previously had other method failures, once with an IUD and once with oral contraceptives (OCs). No association was found with carcinoma of the cervix. Of 80 women ceasing treatment to become pregnant, only 1 women has required the assistance of chlomiphene and conceived 2 years after ceasing DMPA. Amenorrhea was the side effect most appreciated by the women using DMPA. Due to the problem of irregular bleeding, it is wise to warn prospective patients about the lack of bleeding control that they have 1 chance in 10 of having relative menorrhagia. Women using OC subject to frequent vaginal moniliasis had a marked reduction in episodes after switching to DMPA. Chloasma, 1 of the minor stigmas of OC, was not induced in any of the patients. DMPA is a safe and efficient reversible method of contraception for women who have various gynecological conditions or problems associated with using OCs.

147 Mexican women, of low socioeconomic level, who had aborted spontaneously and desired pregnancy, were subjected to trial of placebo oral contraceptive. In 424 months there were 72 pregnancies, a Pearl index of 203.8 pregnancies per 100 couple-years. Menstrual cycles lasted 21-24 days in 30 women (9.8%), 25-35 days in 235 (76.8%), and 36-59 days in 38 (12.4%). 18 cycles (5.8%) were marked by intermenstrual bleeding. Incidence of 31 side effects is listed. Most common were: decreased libido 125 months (29.5%), headache 66 (15.6%), lower abdominal pain and bloating 58 (13.7%), dizziness 47 (11.1%). Common complaints were nervousness, increased libido, dysmenorrhea, nausea, epigastric pain, leg pain, leukorrhea, somnolence. Oral contraceptive-like side effects reported in fewer than 1% of months included acne, mastalgia, increased appetite, weight gain, painful varicose veins. Nausea (here 4.2% of months) was the only side effect with markedly different incidence from other studies with active oral contraceptives.
