mgaspirin

mgaspirin is a term used to describe preparations of acetylsalicylic acid (ASA) formulated in milligram doses for oral use. ASA is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, anti-inflammatory, and antiplatelet properties. The antiplatelet effect arises from irreversible inhibition of COX-1 in platelets, reducing thromboxane A2 formation, which lowers platelet aggregation; the anti-inflammatory effects are through COX-2 inhibition, though ASA is non-selective.

Oral mgaspirin is rapidly absorbed from the gastrointestinal tract, with peak salicylate levels within 1-2 hours. The drug is largely protein-bound and metabolized in the liver to salicyluric and other metabolites, with renal excretion. The half-life increases with dose (dose-dependent).

Indications: mgaspirin is used for mild to moderate pain, fever, and to reduce risk of ischemic events in certain adults at low-dose regimens (often 75-100 mg daily). It is also used in short-term management of acute coronary syndrome under medical supervision.

Contraindications include active peptic ulcer disease, history of gastrointestinal bleeding, severe hepatic or renal impairment, and known aspirin allergy. It should not be given to children or teenagers with fever or viral infections due to the risk of Reye's syndrome. Caution is advised in the elderly and during pregnancy unless benefits outweigh risks; in late pregnancy, risk to the fetus is a concern.

Safety and interactions: concomitant anticoagulants, other NSAIDs, corticosteroids, or alcohol can increase bleeding risk. Adverse effects may include gastrointestinal irritation, gastritis, ulceration, bleeding, tinnitus at higher doses, and hypersensitivity reactions.

Regulatory status: mgaspirin is sold as an over-the-counter analgesic/antipyretic in many markets as tablets, often in enteric-coated or buffered forms. For chronic use, medical advice is recommended.
