In this in vivo study, oil solutions of the N,N-diethyl glycolamide ester prodrug of naproxen (16mg/ml) were injected into the rat knee joint by dosing 6μl formulation per 100g body weight. The sustained release properties were compared to those of intra-articularly injected aqueous and oil solutions of naproxen by monitoring the naproxen serum concentrations over time. Two oils, medium-chain triglycerides and castor oil, differing with respect to viscosity were tested. After intra-articular administration of oil prodrug solutions, a significant increase in the time to maximum naproxen serum concentration from around 40 to 245min, an increase in the MRTj from around 0.11 to 3.3h and a 30{\%} reduction in the maximum serum concentration were observed compared to that of the parent naproxen. The similar serum profiles obtained using the two oils indicate that the release was not affected by the oil viscosity.
