Levonorgestrel-only emergency contraception: real-world tolerance and efficacy
Contraception
|September 6, 2001
Summary
Levonorgestrel-only emergency contraception is well-tolerated and effective in real-world use. This method demonstrates a low pregnancy rate, similar to clinical trials, reducing unintended pregnancies.
Area of Science:
- Reproductive Health
- Pharmacology
- Public Health
Background:
- Levonorgestrel-only emergency contraception (LNG-EC) launched in France in May 1999.
- It followed a trial showing superior efficacy and tolerance to combined methods.
Purpose of the Study:
- Evaluate real-world tolerance and efficacy of LNG-EC.
- Assess physician practices and perceptions of LNG-EC.
Main Methods:
- Retrospective study in France.
- Questionnaire distributed to 100 physicians; 82 responded.
- Data collected on prescription practices, tolerance, and efficacy from over 2,000 administrations.
Main Results:
- Physicians reported LNG-EC as well-tolerated.
- No unexpected side effects were observed.
- Pregnancy rate remained below 3%, consistent with clinical trial data.
Conclusions:
- LNG-EC demonstrates considerable real-world efficacy.
- The method is effective in reducing unintended pregnancies.
- Physician-reported data support the product's favorable profile.

01:22Dose-Response Relationship: Potency and Efficacy
The potency of a drug is the measure of its ability to produce a biological response and can be compared by looking at the half-maximum effective concentration or EC50 values of different drugs. A lower EC50 value indicates higher potency of the drug. In the dose–response curve of two antihypertensive drugs, candesartan and irbesartan, a significant difference is observed in their EC50 values. A lower EC50 value for candesartan indicates that it is more potent than irbesartan, as it produces...
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...
01:18Drug Delivery: Enteral Route
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

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...
01:19Modified-Release Drug Delivery Systems: Overview
Modified-release dosage forms are designed to address the limitations of drugs with short biological half-lives. These forms maintain stable therapeutic drug concentrations over extended periods, reducing the need for frequent dosing. A consistent drug level helps minimize peak-trough fluctuations, which can reduce adverse effects, lower the risk of drug resistance, and improve overall treatment effectiveness.One common type of modified-release form is the extended-release (ER) formulation. ER...
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...
