📺 Video Overview
Introduction
A 126‑year‑old molecule that still saves lives every hour.
Despite the rise of P2Y₁₂ inhibitors and DOACs, plain aspirin 325 mg remains the first drug every ambulance carries for chest‑pain calls worldwide. India’s USV Pharma formulates Ecosprin™ 325 mg with an enteric coat that minimises gastric irritation yet dissolves rapidly in intestinal pH. The 14‑tablet strip targets two clinical niches: (1) emergency chew‑dose for acute MI (one strip covers two events), and (2) short‑term analgesic/antipyretic use in adults. Routine secondary‑prevention now prefers 75–150 mg, but 325 mg retains guideline endorsement for loading pre‑PCI or in the face of suspected stroke when CT unavailable. (The full 2 500‑word intro inside the canvas details historical milestones, guideline shifts, Indian OTC landscape, and pharmacoeconomic metrics.)
Mechanism of Action
| Level | Effect | Clinical Result |
| Platelet | Irreversible acetylation of COX‑1 → ↓ TXA₂ | Platelet inhibition ≥ 90 % for lifespan (7–10 d) |
| CNS/Pain | COX‑2 block (partial) → ↓ prostaglandins | Analgesia / antipyresis |
| Vascular | ↓ CRP & IL‑6 (anti‑inflammatory) | Plaque‑stability benefit |
Peak platelet inhibition ~ 30 min when chewed or dispersed; enteric swallow ≈ 3 h — chew in emergencies.
