Summary
Oral contraceptive prescriptions remain high, with stable doses. Parenteral contraceptives like Norplant and Depo-Provera show rapid acceptance and increasing distribution in the United States.
Area of Science:
- Reproductive Health
- Pharmaceutical Sciences
- Public Health
Background:
- Steroidal contraceptives are a cornerstone of reproductive health.
- Understanding current trends in contraceptive use is crucial for public health planning.
- Previous data on contraceptive utilization requires regular updates.
Purpose of the Study:
- To provide updated data on steroidal contraceptive use in the United States.
- To analyze trends in the utilization and distribution of oral contraceptives, Norplant, and Depo-Provera from 1989 to 1994.
Main Methods:
- Analysis of pharmaceutical marketing data.
- Examination of prescription data for oral contraceptives.
- Tracking distribution data for Norplant and Depo-Provera.
Main Results:
- In 1994, 56.8 million oral contraceptive prescriptions were dispensed.
- Oral contraceptive formulations maintained stable estrogen and progestin doses, averaging 34 microg ethinyl estradiol.
- Increased mentions of oral contraceptive use were observed in women aged 35-44.
- From 1991-1994, approximately 169,000 Norplant systems were distributed.
- Over 1.5 million milliliters of Depo-Provera were distributed between 1993 and 1994.
Conclusions:
- Oral contraceptives continue to be a widely used and popular method of contraception.
- Injectable and implantable steroidal contraceptives (parenteral formulations) have demonstrated rapid market acceptance and increasing utilization.

01:25Drug Regulation
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...
01:22Hormonal Regulation of the Menstrual Cycle
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

01:22Birth Control Methods
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...
01:22Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence
Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery. A 3 g dose typically provides...
01:26FDA Approved Drugs: Changes to Approved Drugs
Post-approval, manufacturers may modify an approved new or generic drug product. Such modifications can encompass alterations in the Active Pharmaceutical Ingredient (API), manufacturing process, formulation, batch size, manufacturing site, and container closure system (FDA Guidance for Industry, April 2004). Often, a drug product may undergo multiple changes.These modifications require careful evaluation to determine their potential impact on the drug product's identity, strength, quality,...
01:21Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
