Abstract
Background: Despite the vast utility of polymeric nanocarriers in drug delivery, their promising role in formulating efficient transdermal drug delivery systems for managing various dis-eases has not been explored properly. Main text: Polymeric nanocarriers have increased the interest of researchers with respect to im-proving intradermal and transdermal delivery of drugs having ominous penetration and solubility issues. Therefore, a range of invasive and noninvasive approaches have been extensively explored in transdermal delivery systems for the safe and effective transportation of drugs across the skin into the systemic circulation. Accordingly, this review emphasizes the recently used, effectively appli-cable invasive and noninvasive methodologies for formulating transdermal systems in the form of polymeric films/patches, microneedles, and nanocarriers for better penetration and bioavailability. Conclusion: Various novel methodologies for transdermal drug delivery systems offer countless benefits over conventional methods, but still, a safe and effective delivery system is the major chal-lenge in terms of reproducible pharmacokinetic and pharmacodynamic results.
