Loprin 75 Tablet contains Aspirin 75 mg, a non-steroidal anti-inflammatory drug (NSAID) with antiplatelet properties primarily used for the prevention of cardiovascular events. Aspirin irreversibly inhibits cyclooxygenase-1 (COX-1) enzyme, leading to decreased synthesis of thromboxane A2, a potent promoter of platelet aggregation. This action reduces the formation of blood clots, thereby lowering the risk of myocardial infarction, ischemic stroke, and other thromboembolic complications in patients with established cardiovascular disease or those at high risk. Loprin 75 is commonly prescribed as a prophylactic agent in individuals with a history of coronary artery disease, transient ischemic attacks, or peripheral arterial disease. It is also utilized in secondary prevention following acute coronary syndrome or percutaneous coronary interventions. The low-dose formulation minimizes gastrointestinal side effects while maintaining antiplatelet efficacy. Patients should take Loprin 75 under medical supervision, as it may increase bleeding risk, particularly in those with peptic ulcers, bleeding disorders, or concurrent use of anticoagulants or other NSAIDs. Caution is advised during pregnancy and in individuals with hypersensitivity to aspirin or salicylates. Regular monitoring and adherence to prescribed dosage are essential to optimize therapeutic outcomes and minimize adverse effects.
