Abstract  Various organic solvents like methanol, chloroform,alcohol, dimethyl form amide; acetonitrile, hexane, acetone and carbon tetra chloride have been employed for stabilization of poorly water-soluble drugs for spectrophotometric estimations. Drawbacks of organic solvents include higher cost, toxicity and error in analysis due to volatility. Attempting to minimize these drawbacks, three new, simple, accurate, environmental friendly, cost effective, safe, sensitive spectrophotometric methods have been developed. Theprimary objective of the present investigation was to employ these hydrotropic solutions to extract the drugs from their dosage forms, precluding the use of costlier organic solvents. Ultraviolet absorption spectrophotometric method for the estimation of poorly water soluble drugs like Melitracen HCl in pharmaceutical formulations has been developed.
