Properties:
Paracetemol is the chief metabolite of anilline derivatives (phenacetin & acetanitide) probably accounts for their analgesic effect
Paracetamol exerts its analgesic action by raising the threshold of response to pain stimuli by interfering with thir relay from the thalamus to the cortex, other forms of sensations however remain completely unaffected. Like salicylates Paramol has antipyretic action, causes depletion of ascorbic acid from the adrenal cortex and reduces inflammatory changes but has no anti-rheumatic effect,
Paracetamol is similar in itS analgesic & antipyretic effect to acetyl - salicytic acid but its free from the gastric irritant side effect induced by the later. Indications and usage: 1- Pain of somatic origin, e.g.: headache, toothache, pain arising from the muscuto- Skeletal system, etc. And as an analgesic in rheumatic diseases.
2- Influenza, common cold and other febrite conditions.
3- Dysmenorrhea.
4-As a suitable allemative to patients sensitive to ecetyl- salicylic acid.
5-When an analgesic is required to patients receiving anticoagulants. Paracetamol is the drug of choice, as the risk of potentiation of the antbcoagulants effect is minimal.
