Formulation and Evaluation of Solid lipid nanoparticles: Isoniazid
Abstract
Tuberculosis is an infectious disease caused by Mycobacterium Tuberculosis which attacks lungs and other parts of the body. Isoniazid is a hydrophilic drug that is having a first line antituberculosis drug. Entrapment Efficiency has been improved by preparing Solid Lipid Nanoparticles (SLNs). Two different variable Stearic acid and Tween 80 were used by using w/o/w double emulsion-solvent evaporation method by using 32 factorial designs. Particle size, Surface Morphology, Entrapment efficiency and In-vitro diffusion studies were evaluated for prepared SLNs. Different combination of Surfactant and Lipid were found to have significant effect on entrapment efficiency but not on drug release. The prepared SLNs were found in spherical shape and 678 nm particle size was found. % Entrapment efficiency were found from 31.90±0.41 to 74.89±0.67. Present Work is focused on increase incorporation of drug into SLN. Work indicates that formulation of SLNs loaded INH can give reliable therapeutic effect for the treatment of tuberculosis by prolonged action.
