Formulation Optimization, In Vitro and In Vivo Evaluation of Niosomal Nanocarriers for Enhanced Topical Delivery of Cetirizine

This study found that while both cetirizine 1% and minoxidil 5% increased hair density in men with androgenetic alopecia, minoxidil showed a significantly higher improvement, and both treatments lost effectiveness after 8 weeks without use; cetirizine was well-tolerated with no significant adverse reactions.

This review discusses various nanoparticles used to enhance skin permeation and target delivery to skin organelles, but reports no new experimental results.

This review article provides an updated overview of the pharmacology, mechanism of action, clinical efficacy, and adverse events associated with topical minoxidil, a widely used treatment for androgenetic alopecia and other hair loss conditions, while noting that its exact mechanism is still not fully understood.

This study highlights that niosomes, or non-ionic surfactant based vesicles, offer an advantageous drug delivery system due to their stability, cost-effectiveness, and ability to enhance drug bioavailability and targeting efficiency for various therapeutic agents.

This study found that topical cetirizine 1% significantly improved hair density and diameter in patients with androgenetic alopecia, with patients tolerating the treatment well.

This systematic review and meta-analysis found that minoxidil, finasteride, and low-level laser light therapy significantly improve hair growth in men with androgenetic alopecia, while minoxidil is also effective for women, compared to placebo.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.

This study found that minoxidil-loaded niosomes with a Span 60 and cholesterol ratio of 1:2 significantly increased skin retention of minoxidil compared to control gel.

This review discusses niosomes' increasing popularity in dermatology for topical drug delivery due to their ability to enhance drug penetration, provide sustained release, and carry various drugs, while reporting no new clinical findings.

PGD2 stops hair growth and is higher in bald men with AGA.

In this study, niosomal formulations enhanced minoxidil skin accumulation compared to commercial and control solutions, suggesting a potential improvement for topical delivery in hair loss treatment.
