Abstract
Rheumatoid/osteoarthritis is one of the most common causes for lacking behind in the health sector. Medication in the form of tablets are already available in the market but has disadvantages. When these medicines are taken orally it cause heartburn and discomfort. The introduction of transdermal drug delivery is expected to solve this problem of side eff ects associated with oral delivery of drug. In the present study, indomethacin was loaded in solid lipid nanoparticles (SLN) which are then embedded in Carbopol gel for transdermal application. The solvent evaporation ultrasonication method was used for making SLNs. The formulation was evaluated for various parameters such as ; particle size and zeta potential of SLN using zetasizer as an instrument and gel formulations were evaluated for pH, spreading coeffi cient, viscosity, visual appearance and clarity. Gel-embedded SLN formulation was found to be a potential transdermal drug delivery system for NSAIDs like indomethacin to treat ailments like rheumatoid arthritis or osteoarthritis.
