## Ecospirin (Aspirin Enteric-Coated)
### Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, and antiplatelet properties. The enteric coating is designed to delay the absorption of aspirin until it reaches the small intestine, potentially reducing gastric irritation.
### Primary Indications
* **Pain and Fever:** Mild to moderate pain and fever.
* **Antiplatelet Therapy:** Prevention of cardiovascular and cerebrovascular events in patients with a history of or at risk for these conditions (e.g., secondary prevention of myocardial infarction, stroke).
### Adult Dosing
* **Pain and Fever:** 325 mg to 650 mg orally every 4 to 6 hours as needed. Maximum daily dose: 4000 mg.
* **Antiplatelet Therapy (Secondary Prevention):**
* 81 mg to 325 mg orally once daily.
* Dosing for acute coronary syndromes may vary and should follow specific guidelines.
### Pediatric Dosing
* **Pain and Fever:** Dosing is typically based on weight. For children aged 2 to 16 years, doses range from 10 mg/kg/dose to 15 mg/kg/dose orally every 4 to 6 hours. Maximum daily dose: 60 mg/kg/day or 4000 mg/day, whichever is less.
* **Important Note:** Aspirin should generally be avoided in children and adolescents with viral illnesses due to the risk of Reye's syndrome.
### Dose Adjustments
No specific dose adjustments are typically required for renal or hepatic impairment, but caution is advised.
### Contraindications
* Hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Active peptic ulceration or history of recurrent ulcers.
* Bleeding disorders (e.g., hemophilia, thrombocytopenia).
* Severe hepatic or renal impairment.
* Severe heart failure.
* Third trimester of pregnancy.
### Adverse Effects
Common: Gastric upset, heartburn, nausea.
Serious: Gastrointestinal bleeding, ulceration, tinnitus, dizziness, allergic reactions (including anaphylaxis), bronchospasm (especially in aspirin-sensitive asthma), Reye's syndrome in children.
### Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of gastrointestinal toxicity and bleeding.
* **Corticosteroids:** Increased risk of gastrointestinal ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** May reduce antihypertensive efficacy.
* **Methotrexate:** Increased risk of methotrexate toxicity.
* **Sulfonylureas:** May enhance hypoglycemic effect.
* **Uricosuric agents (e.g., probenecid):** May reduce the efficacy of uricosuric agents.
### Monitoring
* Monitor for signs and symptoms of gastrointestinal bleeding (e.g., melena, hematemesis, abdominal pain).
* Monitor for signs of tinnitus or hearing impairment.
* Monitor for signs of hypersensitivity reactions.
* In patients on long-term therapy for cardiovascular prevention, monitor for bleeding events.
### Clinical Pearls
* The enteric coating helps to reduce gastric irritation but does not eliminate the risk of gastrointestinal bleeding. Advise patients to take with food if stomach upset occurs, although this may delay absorption.
* Aspirin should be used cautiously in patients with asthma, nasal polyps, and chronic urticaria.
* Do not crush or chew enteric-coated aspirin.
* Avoid concurrent use with other NSAIDs unless specifically indicated and with caution.
