Composition
Paragesic tablet: Each tablet contains Paracetamol BP 500 mg.
Pharmacology
Paragesic is the formulation of Paracetamol which is one of the safest and most widely used analgesic and antipyretic. Paragesic produces analgesic action by elevation of pain threshold and antipyresis through action on the hypothalamic heat regulating center. Paragesic exerts significantly milder side effects and most unlikely to produce many of the side effects associated with Aspirin and NSAIDs.
Paracetamol is rapidly and completely absorbed from the GIT following oral administration. The drug is extensively metabolized in liver and it has plasma half life of 1.5 to 3.0 hours. Paracetamol is not bound to plasma proteins to any extent.
