Methocel E4M: Preparation and properties as a vehicle for the ocular drug delivery of vancomycin
In this study, hydroxypropyl methylcellulose (HPMC, Methocel™ E4M) was chosen in 0.3% and 0.4% w/v concentrations at pH 7.1 as an ocular drug delivery vehicle for vancomycin and its in vitro characteristics and stability determined. The viscosity, osmolality, clarity, pH and contamination of each of...
