Aspiriiniin

Aspiriiniin is the Finnish term associated with aspirin, the widely used over‑the‑counter medicine whose active ingredient is acetylsalicylic acid (ASA). In pharmacology, aspirin is classified as an analgesic, anti-inflammatory, antipyretic, and antiplatelet drug. It was first synthesized in the late 19th century, with widespread medical use following its approval in the early 20th century. In the body, aspirin irreversibly inhibits cyclooxygenase enzymes (COX‑1 and COX‑2), lowering the production of prostaglandins and thromboxanes, which reduces pain, inflammation, and platelet aggregation.

Common indications include mild to moderate pain, fever, and inflammatory conditions. Low‑dose aspirin regimens (often around 75–100 mg daily) are used to reduce the risk of heart attack or ischemic stroke in certain high‑risk patients under medical supervision; it is not suitable for everyone. Children and teenagers with viral infections should not take aspirin due to the risk of Reye’s syndrome.

Safety and interactions are important. Potential side effects include stomach upset, gastritis, ulcers, and increased bleeding risk; aspirin allergy can occur; it can interact with anticoagulants, other NSAIDs, alcohol, and certain medical conditions such as active gastrointestinal bleeding or severe kidney disease. Contraindications include known aspirin allergy and certain pregnancy situations; always consult a clinician before starting or stopping therapy.

Dosing guidelines vary by indication. For analgesia, adults may use 325–1000 mg every 4–6 hours as needed, not exceeding about 4 g per day. For cardioprotection, lower doses (75–100 mg daily) are commonly prescribed under medical supervision.
