# 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 release of aspirin until it reaches the small intestine, potentially reducing gastric irritation.
## Primary Indications
* **Pain and Inflammation:** Mild to moderate pain and inflammation associated with conditions such as osteoarthritis, rheumatoid arthritis, and dysmenorrhea.
* **Cardiovascular Prevention:** Secondary prevention of myocardial infarction and stroke in patients with established cardiovascular disease, and primary prevention in select high-risk individuals.
* **Antiplatelet Therapy:** To reduce the risk of thrombotic events.
## Adult Dosing
* **Pain and Inflammation:**
* Typical dose: 325 mg to 650 mg orally every 4 to 6 hours as needed.
* Maximum dose: 4000 mg per day.
* **Cardiovascular Prevention/Antiplatelet Therapy:**
* Low-dose aspirin: 75 mg to 162 mg orally once daily. Specific dosing often guided by cardiovascular risk assessment and local protocols.
## Pediatric Dosing
* **Pain and Inflammation:** Aspirin is generally **not recommended** for use in children and adolescents (under 19 years of age) due to the risk of Reye's syndrome, particularly during viral illnesses.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe impairment.
* **Hepatic Impairment:** Use with caution.
## Contraindications
* Known hypersensitivity to aspirin, NSAIDs, or salicylates.
* Children and teenagers with viral infections (due to risk of Reye's syndrome).
* Active peptic ulcer disease.
* Bleeding disorders.
* Severe renal or hepatic impairment.
* Use in the third trimester of pregnancy.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, GI bleeding, ulceration.
* **Hematologic:** Increased bleeding risk, bruising, petechiae.
* **Hypersensitivity:** Bronchospasm (especially in aspirin-sensitive asthma), urticaria, angioedema.
* **Other:** Tinnitus (salicylism), dizziness, headache.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Methotrexate:** Increased methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics, beta-blockers):** NSAIDs can reduce their efficacy and increase the risk of renal dysfunction.
* **Uricosuric agents (e.g., probenecid):** Aspirin can interfere with their uricosuric effect.
## Monitoring
* **Bleeding:** Monitor for signs and symptoms of GI bleeding (melena, hematemesis) and increased bruising.
* **Renal Function:** Assess periodically, especially in patients with pre-existing renal disease or those on long-term therapy.
* **Hepatic Function:** Assess periodically, especially in patients with pre-existing hepatic disease.
* **Tinnitus:** May indicate salicylism and the need to reduce the dose or discontinue therapy.
## Clinical Pearls
* The enteric coating may delay absorption, so onset of pain relief may be slower compared to non-enteric coated formulations.
* Enteric-coated aspirin should be swallowed whole and not crushed, chewed, or broken to preserve the coating.
* Aspirin's antiplatelet effect is irreversible and lasts for the life of the platelet (7-10 days).
* Always consider the risk of Reye's syndrome when prescribing aspirin for pediatric patients.
