Research on the preparation of paracetamol 650 mg prolonged-release tablets

Paracetamol is one of the most commonly used active ingredients, even without a doctor's prescription for most people. It has effects on relieving pain and treating fever, especially with an analgesic effect for the elderly who have to suffer from degenerative joint disease. However, the half-life of paracetamol is relatively short, from 1 to 3 hours, so patients need to use it many times a day.
