Methodspre-formulation studies determination of solubility of timolol maleate By using the shake flask method, the solubility of Timolol maleate in aqua, ethyl alcohol, PBS pH 6.8, PBS pH 7.4, and ether was measured. In a flask containing 10 ml of each solvent, an excess amount of the medication was introduced. The mixtures were then agitated at 100 rpm for 24 hours inside a thermostatically managed water bath at 370.5°C, filtered, diluted, and spectrophotometrically assessed at 294.4 nm using a UV spectrophotometer against a blank that had been treated similarly. 5
Standard curve for timolol maleateThe medication (10 mg) was precisely weighed and put within a 100 mL measuring flask. To make this stock solution-I, the drug was dissolved in 7.4 pH buffer solution and diluted until 10 mL with the similar
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
