Introduction:
Intrauterine devices (IUDs) are drug-device combination products that are placed inside the uterus above the endometrium. IUDs contain a therapeutic agent used for contraception and have been shown to have other therapeutic benefits. Over the past century, intrauterine drug delivery systems (IUDDS) have revolutionized women's health, and they hold immense growth potential in the future for new developments in the therapeutic areas beyond contraception.
Areas Covered:
The aim of this review is to offer a comprehensive description of the history, development, and current state of IUDDS, next-generation IUDDS, and future applications of IUDDS in therapeutic areas beyond contraception such as multi-purpose prevention technologies, hormone replacement therapy, endometriosis, uterine fibroids, and endometrial cancer.
Expert Opinion:
The uterus's unique features make it an ideal site for controlled, prolonged, and localized delivery of drugs, ensuring maximum concentration at the target site. Currently, IUDs are the most widely used contraceptive method. Future IUDDS hold the potential to deliver therapeutic agents for broader therapeutic areas for women's health, potentially aiding in the treatment of various diseases and disorders of the female reproductive system. Further research in development, characterization, and translation is warranted to ensure IUDDS reach their potential in many areas of women's health.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
