Choosing condoms.

Condoms for men are currently the most effective of the nonprescription contraceptive methods. They are readily available, simple to use, and relatively inexpensive, and they are not associated with major adverse effects. If used both properly and consistently, condoms can significantly reduce the risk of transmission of HIV and other STDs. The protection offered by the latex condom may be increased by the concurrent use of a vaginal foam or cream containing nonoxynol 9. The practicing pharmacist should know about the variety of condoms available, be able to explain their correct use to maximize effectiveness, and compare condom use with other types of contraceptives. The practitioner should be available to answer patrons' questions and provide counseling on contraceptives and "safe sex" practices.

Contraception for midlife women.

Women wish to continue to be sexually active long after their desire to bear children. The risks associated with unintended pregnancy easily can be avoided by providing women with information about, and access to, contraceptives that are safe and effective. Because fertility naturally declines with age, different contraceptives may be more suitable for women toward the end of their reproductive years than were appropriate at periods of peak fertility. This article discusses the risks and benefits of various contraceptives for midlife women and the implications of this information on nursing practice.

Clinical evaluation of drugs used in fertility regulation.

The clinical evaluation of drugs used in fertility regulation is initially assessed in Phase I, II and III trials. The design of each phase and the investigative staff must be adequate. In Phase I, normal, healthy human volunteers meeting specific guidelines are usually studied. Numbers vary between 20 and 80 and the purpose is to determine the acute toxicity of the compound. In Phase II, efficacy and safety are examined in a clinical target population, and emphasis may be placed on pharmacological and mechanistic studies. Usually between 50 and 200 patients are involved. In Phase III, large-scale clinical studies for local registration and the introduction of drugs to various countries are included. This paper describes the evaluation of various drugs used in contraception, including NORPLANT implants, and considers the efficiency, safety and acceptability of such drugs. Phase IV studies are usually needed to reveal chronic toxicities or rare events.

[Vaginal and intrauterine contraception].

Vaginal contraception (condom, diaphragm and spermicide in pessary, tablet, jelly, cream, or sponge form) have been little used in France and generally in Europe since the advent of modern contraception with "the pill" and the intrauterine contraceptive device. The former methods, when properly used, are nevertheless both effective and useful, at least as interim measures. In addition, the protection they afford against sexually transmitted diseases and, for the condom, against HIV, is not negligible. Finally, the "barrier" methods of contraception such as the diaphragm and the condom afford significant protection against cancer of the cervix. The intrauterine contraceptive device (IUCD), used in France by 14% of women between 15 and 49 years of age and by 90 million women throughout the world for whom it is the main reversible means of contraception, have a mechanism of action that is still not fully understood. Most IUCD now used are made of copper. There are also diffusion IUCD based on progesterone or a synthetic progestational hormone which are useful in case of anaemia, menorrhagia or dysmenorrhea.
