Application


  • Novel transdermal bioadhesive surfactant-based system for release and solubility improvement of antimalarial drugs artemether-lumefantrine: This study utilizes 1-Methyl-2-pyrrolidone (NMP) as a high-purity solvent in the formulation of a transdermal bioadhesive system, enhancing the solubility and delivery of antimalarial drugs. The application highlights NMP′s role in pharmaceutical formulations, particularly in improving drug efficacy and patient compliance (Volpe-Zanutto et al., 2021).
