research Development and Characterization of Film Forming Spray of 5% Minoxidil for Baldness Due to Androgenetic Alopecia
This study explores a film-forming spray with 5% minoxidil for treating androgenetic alopecia, aiming to reduce side effects like dry scalp and irritation associated with traditional formulations. The spray forms a thin, non-sticky film that enhances drug contact time and permeability, leading to continuous release and improved patient comfort. The formulation was evaluated for pH, viscosity, spray angle, and drug content, with formulation F2 (1.8% hydroxypropyl methylcellulose E15) showing promising results. The study concludes that this novel delivery system could effectively treat patchy hair loss or baldness in men with androgenetic alopecia, improving therapeutic outcomes and patient compliance.
