A study is presented which was designed to compare Solpadeine (paracetamol 500 mg, codeine phosphate 8 mg and caffeine 30 mg) and soluble DNP (dextropropoxyphene napsylate, equivalent to 32.5 mg hydrochloride and paracetamol 325 mg) in the control of pain following wisdom teeth extraction. A higher percentage of patients found Solpadeine more effective and significantly more Solpadeine patients considered their treatment easier to take.
