Enhancement of Drug Dissolution of Erlotinib Tablets by Micronization Technique Using Pharmaceutical Experimental Design

Lung cancer is the second most frequent cancer and among the top cause of death worldwide. Chemotherapy is the main therapeutic option for non-small-cell lung cancer (NSCLC), which accounts for the majority of all lung malignancies. The aim of the current work was to develop a tablet formulation having increased drug release profile to improve the bioavailability in order to reduce the dose of the drug. In this present study, Erlotinib tablet was prepared using micronization technique which showed increase drug release profile. Film-coated tablets containing Erlotinib hydrochloride (150 mg) were prepared by dry granulation technique and coated using Opadry ready-mix. Tablets were characterized for Hardness, Friability, Potency and Drug release profile. Drug release was checked in 0.1 N HCL containing 0.5 % SLS and biorelevant dissolution media up to 60 minutes. Tablets of the selected batch were subjected to dissolution in biorelevant media and compare with reference product. The improvement in the drug release was observed in the biorelevant media in comparison with reference product. The in-vitrodissolution data demonstrated the potential of micronization technology to prepare tablets with improved bioavailability of the drug.
