COMPARATIVE STUDY OF SEMI-SOLID BASES OF NAPROXEN: PHARMACEUTICAL TECHNOLOGY ASPECTS

Abstract

Objective: The main objectives of the present investigation work included that the preparation of a suitable naproxen semi-solid dosage form by using different types of semi-solid bases (gel bases, ointment bases) for topical application for the effective treatment of muscle aches. Methods: Different types of semi-solid bases (gel bases and ointment bases) were successfully prepared by the incorporation method to know the effect of semi-solid bases on drug release from topical semi-solid formulations. In all formulations, the drug was added by the levigation method. An evaluation study of prepared formulations, includes physical appearance, spreadability, extrudability, pH was conducted according to official methods. Results: Percent drug release of all formulations was conducted by taking diffusion cells with cellophane membrane and results showed that gel-based formulations showed more drug release than ointment-based formulations. Carbopol gel base (F1) showed more drug release (98.76 %), simple ointment base formulation (F8) showed least drug release (25.11%). From the stability studies reports at various temperature and humidity conditions it is evident that all formulations are stable for one month. In all the formulations, the drug content was observed at 95.75%. Conclusion: Finally concluded that the NXN topical dosage forms can be prepared by using gel-type bases preferably than ointment bases to release more drug from formulations.
