Propacetamol

Propacetamol is an alpha-amino acid ester.|Propacetamol is a non-opioid analgesic devoid of the major contraindications. It is a derivative of [acetaminophen], or paracetamol, with the molecular formula glycine, N, N-diethyl-,4-(acetylamino)phenyl ester. Propacetamol is a parenteral formulation of paracetamol and thus, it is a prodrug that is completely hydrolyzed to paracetamol. It is not available in the United States but this prodrug has been widely used in other countries such as France since 1985.|Propacetamol is a water-soluble para-aminophenol derivative and ester prodrug of acetaminophen in which acetaminophen is bound to the carboxylic acid diethylglycine, with analgesic and antipyretic activities. Upon intravenous administration, propacetamol is hydrolyzed by plasma esterases into its active form acetaminophen. Although the exact mechanism of action has yet to be fully elucidated despite its widespread use, acetaminophen enters the central nervous system and acts centrally. This agent binds to cyclooxygenase (COX) and prevents the metabolism of arachidonic acid to prostaglandin. A reduction in prostaglandin formation relieves pain and reduces fever. Acetaminophen may also act centrally on cannabinoid receptors and on N-methyl-D-aspartate (NMDA) receptors.
