PHARMACOLOGY

By decreasing platelet aggregation, Aspirin inhibits thrombus formation on the arterial side of the circulation, where thrombi are formed by platelet aggregation and anticoagulants have little effect. Aspirin is the analgesic of choice for headache, transient musculoskeletal pain and dysmenorrhoea. It has anti-inflammatory and antipyretic properties, which may be useful. Enteric-coated Aspirin reduces intestinal disturbance and gastrointestinal ulceration due to aspirin.

Long-term use of aspirin in a dose of 75 mg daily is recommended thereafter.Acute ischaemic stroke/Transient ischaemic stroke (TIA): The starting dose is 150 mg-300 mg daily and Aspirin 75 mg daily thereafter.Following bypass surgery: 75 mg-300 mg daily starting 6 hours post-procedure.

INTERACTION

Salicylates may enhance the effect of anticoagulants, oral hypoglycaemic agents, phenytoin and sodium valporate. They inhibit the uricosuric effect of probenecid and may increase the toxicity of sulphonamides. They may also precipitate bronchospasm or induce attacks of asthma in susceptible subjects.

SIDE EFFECTS

PREGNANCY & LACTATION

Aspirin penetrates into breast milk. So, it should be administered with caution to lactating mothers.
