Transdermal delivery of contraceptives

Area of Science:

• Pharmacology
• Dermatology
• Reproductive Health

Background:

• Contraceptive agents are administered via various routes.
• Transdermal delivery is a novel approach for systemic contraceptive agents, including estrogens and progestins.

Purpose of the Study:

• To review skin permeability and metabolism of contraceptive steroids.
• To discuss transdermal delivery systems for contraceptive agents.
• To address potential skin irritation with chronic use.

Main Methods:

• Review of scientific literature on transdermal contraceptive delivery.
• Evaluation of skin permeability and metabolism of contraceptive steroids.
• Analysis of existing and emerging transdermal delivery systems.

Main Results:

• Transdermal route offers potential advantages: improved compliance, weekly administration, easy termination, and consistent delivery rates.
• Skin permeability and metabolism are key factors in transdermal contraceptive efficacy.
• Specific delivery systems for levonorgestrel and estradiol are discussed.

Conclusions:

• Transdermal contraceptive delivery systems show promise for enhanced patient compliance and potentially fewer side effects.
• Further research into optimizing delivery systems and managing skin irritation is warranted.
