Abstract

Transdermal drug delivery offers significant advantages for administering non-steroidal anti-inflammatory drugs (NSAIDs) and anti-complementary drugs, particularly those with poor water solubility. This delivery route bypasses first-pass metabolism and gastrointestinal degradation, enhancing bioavailability and patient compliance. However, the stratum corneum, the outermost layer of the skin, poses a formidable barrier to drug permeation. To address this challenge, several innovative strategies have been developed to improve the transdermal delivery of these poorly soluble drugs.

Chemical enhancers, such as alcohols, fatty acids, and surfactants, can disrupt the lipid structure of the stratum corneum, increasing drug solubility and permeability. Nanoformulations, including liposomes, niosomes, solid lipid nanoparticles, and nanoemulsions, enhance drug solubility, provide protection against degradation, and facilitate controlled release with deeper skin penetration. Prodrugs, designed to convert into the active drug within the skin, can improve solubility and permeability. Physical methods like microneedles, iontophoresis, and phonophoresis create micropores or use electrical and ultrasound waves to enhance permeation without compromising skin integrity.

Cyclodextrins form inclusion complexes with drugs, boosting solubility and stability. Hydrogels and polymer-based formulations create a moist environment for sustained drug release and better absorption. Co-solvents and surfactants, such as ethanol and DMSO, further enhance solubility and disrupt the stratum corneum to facilitate drug penetration. Electroporation and thermal ablation transiently disrupt the skin barrier, significantly improving drug permeation.

These strategies, individually or in combination, hold promise for optimizing the transdermal delivery of poorly water-soluble NSAIDs and anticomplementary drugs, ensuring effective therapeutic outcomes and improved patient compliance.
