The study on interaction and complexation of drug molecules with other drugs and various metal ions is an important field of research in the chemical, biochemical, medicinal and pharmacological point of views. The biological action of the drug-metal complexes may affect stability and usual activities of drugs through changing pharmacokinetic and pharmacodynamic properties. The analgesic activity was evaluated by acetic acid induced writhing test in mice. In this experiment, aspirin with magnesium sulfate at the dose of 300 mg, 600 mg and 1.5 g/60 kg body weight, Paracetamol with magnesium sulfate at the dose of 500 mg, at the dose of 1 g and of 2.5 g /60 kg body weight and Naproxen with magnesium sulfate at the dose of 500 mg, at the dose of 1 g and at the dose of 2.5 g/60 kg body weight at a ratio of 1:1, 1:2 and 2:1. It was observed that % inhibition of writhing test of all complex drug of aspirin, paracetamol and naproxen with magnesium sulfate at different ratio were less than the main drug i.e. analgesic activity were lower than the main drug. It is concluded that magnesium sulfate while formed complex as well as mixed with aspirin, paracetamol and naproxen at different ratio suppress the analgesic activity of main drug.
