A Review of Hydrotropic Solubilization Techniques for Enhancing the Bioavailability of Poorly Soluble Drugs

Hydrotropic solubilization is a technique that can be used to improve the solubility of drugs that are poorly soluble. This technique involves adding a large amount of a second solute, known as a hydrotrope, which increases the aqueous solubility of the poorly soluble drug. Hydrotropes such as sodium citrate, sodium benzoate, and urea have been shown to be effective in enhancing the solubility of poorly soluble drugs. This technique has several advantages over other solubility enhancement techniques, including its cost-effectiveness, eco-friendliness, and the fact that it does not require chemical modification of hydrophobic drugs or the use of organic solvents. Hydrotropic agents are now being used to develop various dosage forms, including solid dispersions, mouth-dissolving tablets, and injections, to improve poorly water-soluble drugs' therapeutic effectiveness and bioavailability. This review paper will provide an overview of hydrotropic solubilization techniques.

Automated summary

Hydrotropic solubilization is a technique that improves the solubility of poorly soluble drugs by adding a hydrotrope. It offers advantages such as cost-effectiveness, eco-friendliness, and the absence of chemical modification or organic solvents.
