This invention unveils two novel, cost-effective, and rapid spectrophotometric methods for quantifying the antiretroviral drug Efavirenz in pharmaceutical formulations. Unlike existing methods like HPLC that are expensive, time-consuming, and require complex equipment, these methods leverage readily available reagen...

The present invention discloses novel spectrophotometric methods for the precise quantification of Rosuvastatin (ROS) in pharmaceutical bulk compounds and solid dosage forms. These methods utilize three distinct solvent systems: methanol (Method I, ?max=236 nm), 2-propanol (Method II, ?max=230 nm), and concentrated ...
