Available in PDF, EPUB and Kindle. Book excerpt: One of the United States Food and Drug Administration's most difficult tasks is the assessment of risk-benefit ratios for a broad spectrum of therapeutic and prophylactic drugs. Furthermore, it is now widely recog nized that no drug, chemical or even natural substance is completely devoid of risk. Nowhere has this issue been the subject of more controversy than with steroidal contraceptive drugs. Regulated as a special class of products because of their prophylactic use in healthy individuals for prevention of pregnancy rather than for treatment of disease, steroid contraceptives drugs undergo more extensive animal safety tests than any other pharmaceutical agent. This view also contemplates the availability of alternative contraceptive measures posing fewer risks, but the use of less effective methods must take into consideration the hazards associated with pregnancy itself. In April 1983, the Food and Drug Administration and the National Insti tutes of Health in cooperation with the World Health Organization, the Population Council, and the Agency for International Development sponsored a three-day workshop to evaluate current guidelines for preclinical safety studies of contraceptive drugs in light of our extensive knowledge of the side effects of marketed products. The meeting included presenta tions by experts in the fields of comparative metabolism, pharmacokinetics, pharmacology, carcinogenicity, toxicology, coagulation, lipid metabolism, epidemiology and pathology at a meeting of the Fertility and Maternal Health Drugs Advisory Committee of the National Center for Drugs and Biologics, Food and Drug Administration.

This book was released on 2012-12-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pharmacokinetic variability of contraceptive steroids is a relatively under-explored area of contraceptive research, and hardly a common point of discussion among those who plan and deliver family planning services. Nevertheless, numerous independent studies over the last 15 years have indicated that women in different regions of the world vary in their pharmacokinetic response to contraceptive steroids. The causes of such variability are not known, but it has important consequences for contraceptive effectiveness. It may also offer insight to the basis of contraceptive side-effects. The impetus for this volume was to collect documentation of pharmacokinetic variability of contraceptive steroids, and to explore both the possible causes and implications of these data. Factors known to affect steroid pharmacokinetics, such as concurrent use of specific medications, are reviewed by Back and Orme. Other factors known to affect endogenous steroid dynamics are presented in chapters by Bradlow, Longcope, Goldin and Snow, because of their possible role in contraceptive steroid pharmacokinetics.

Book excerpt: The Center for Population Research of the National Institute of Child Health and Human Development began operations in August 1968 and is engaged in research dealing with health-related popula tion problems.

These studies were initiated several years ago at the specific direction of Congresso We were pleased, therefore, with the opportunity to help organize and support this important and timely conference on the "Metabolic Effects of Gonadal Hormones and Contraceptive Steroids," the subject of which forms an integral part of the Center's research program. April, 1969 Philip Ao Corfman Director Center for Population Research National Institute of Child Health and Human Development v PREFACE Progress in science is often associated with either a "sixth sense" or an inevitable timeliness. Both factors, perhaps, led the members of the Endocrinology Study Section of the National Institutes of Health to propose, in 1966, that an expanded view of the effects of gonadal hormones, in general, and the contra ceptive steroids, in particular. was needed. There had been ample evaluations of the clinical symptomatology, contraceptive efficacy, and effects on the reproductive system, but there was a dearth of information on their multiple systemic'metabolic effects.

This book was released on 1999 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates evidence for an increased risk of cancer in women using combined oral contraceptives, progestogen-only hormonal contraceptives, post-menopausal estrogen therapy, and post-menopausal estrogen-progestogen therapy. Although the carcinogenicity of these preparations has been extensively investigated, the book stresses the many complex methodological issues that must be considered when interpreting findings and weighing results. Evidence of an association between use of these preparations and positive effects on health, including a reduced risk of some cancers, is also critically assessed. The first and most extensive monograph evaluates evidence of an association between the use of combined oral contraceptives and cancer at nine sites. Concerning breast cancer, the evaluation concludes that, even if the association is causal, the excess risk for breast cancer associated with patterns of use that are typical today is very small. Studies of predominantly high-dose preparations found an increased risk of hepatocellular carcinoma in the absence of hepatitis viruses. Citing these findings, the evaluation concludes that there is sufficient evidence in humans for the carcinogenicity of combined oral contraceptives. The evaluation also found sufficient evidence for the carcinogenicity of some, but not all, combined preparations in animals. Combined oral contraceptives were classified as carcinogenic to humans. The evaluation also cites conclusive evidence that these agents have a protective effect against cancers of the ovary and endometrium. Progestogen-only contraceptives are evaluated in the second monograph, which considers the association with cancer at six sites. The evaluation found no evidence of an increased risk for breast cancer. Although the evaluation found sufficient evidence in animals for the carcinogenicity of medroxyprogesterone acetate, evidence for the carcinogenicity of progestogen-only contraceptives in humans was judged inadequate. Progestogen-only contraceptives were classified as possibly carcinogenic to humans. The third monograph, on post-menopausal estrogen therapy, considers evidence of an association with cancer at eight sites. Findings from a large number of epidemiological studies indicate a small increase in the risk of breast cancer in women who have used these preparations for five years or more. Studies consistently show an association between use of post-menopausal estrogen therapy and an increased risk for endometrial cancer. Data on the association with other cancers were either inconclusive or suggested no effect on risk. The evaluation concludes that post-menopausal estrogen therapy is carcinogenic to humans. The final monograph evaluates the association between the use of post-menopausal estrogen-progestogen therapy and cancer at four sites. The evaluation of limited data on breast cancer found an increased relative risk observed with long-term use. Data were judged insufficient to assess the effects of past use and of different progestogen compounds, doses, and treatment schedules. For endometrial cancer, the evaluation found an increase in risk relative to non-users when the progestogen was added to the cycle for 10 days or fewer. Post-menopausal estrogen-progestogen therapy was classified as possibly carcinogenic to humans. Concerning post-menopausal therapy in general, the book notes that evidence of carcinogenic risks must be placed in perspective of potential benefits. The prevention of osteoporotic fractures is cited as the best-established benefit. Evidence also suggests that estrogen prevents heart disease and may prevent memory loss and dementia.
