abstract: background: a new type of drug delivery system known as mucoadhesive film has been developed for oral thrush treatment. due to comfortable use of this drug delivery system, this would be encouragingly utilized, especially in babies and patient under chemotherapy. nystatin mucoadhesive film (nmf) is a polymeric film which is adhered to front upper gum and back to the upper lip and rele...

For the first time, relative distributions of optical and geometrical isomers in selected propylene glycol acetals are determined. Resolution of the four acetal isomers possible through the reaction of racemic propylene glycol (PG) with selected aldehydes is demonstrated. The four isomers are ascribed to the presence of syn and anti geometrical isomers for each optically active PG acetal enanti...

Time-resolved fluorescence depolarization measurements of the S& electronic absorption band of rhodamine B in glycerol and propylene glycol have been made at different excitation wavelengths. It was found that electronic excitation transport between the rhodamine B chromophores is dispersive in glycerol at room temperature and in propylene glycol below 250 K. This demonstrates inhomogeneous bro...

Topical microemulsion of capsaicin without surfactant was developed in this study. In these systems, the oil phase was benzyl alcohol, and the cosurfactant was propylene glycol and ethanol. The drop-size of the systems was measured by dynamic light scattering method in order to distinguish true solution from microemulsion. The transdermal performance of the microemulsions was evaluated in vitro...
