SOLUBILITY ENHANCEMENT METHODS WITH IMPORTANCE OF HYDROTROPY
Abstract
The effectiveness of formulation depends particularly on how efficiently is drug available at the site of action. Therapeutic effectiveness of a drug basically depends upon bioavailability and the solubility of drug moiety. Â Most of the chemical entities that are being discovered are lipophilic and have poor aqueous solubility. A more than 40% drug suffers from poor water solubility. Currently number of techniques addressed the enhancement of solubility and dissolution rate of poorly soluble drugs. Hydrotropic solubilization is one of them. Hydrotropy is a solubilization phenomenon whereby addition of large amounts of a second solute results in an increase in the aqueous solubility of another solute. A hydrotrope is a compound that solubilises hydrophobic compounds in aqueous solutions. To solubilize water insoluble drugs especially in case of oral formulation, solubility remains a critical factor so for in this review various solubility enhancement techniques are highlighted and a brief review of hydrotropy and its preparation are discussed.
