RESUMO
Ketorolac tromethamine (KT) is a non-steroidal anti-inflammatory drug that belongs to class of heteroacetyl derivatives. An attempt has been made to make use of ointments, creams and gels as suitable vehicles for KT, which will released the drug effectively on surface when applied topically. Formulations belongs to ointment, cream and gel bases containing 1% KT were prepared and were evaluated for physiochemical parameters like physical appearance, pH, viscosity, spreadability, drug content. Drug release was also studied by in-vitro techniques. Viscosity was found highest in ointment formulation F3 Gel formulation showed better extrudability and spreadability as compared to ointment and creams. Gel formulation showed better release as compared to ointment and creams.
