# Ecospirin (Aspirin Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) that inhibits platelet aggregation. The enteric coating is designed to delay the dissolution of the tablet until it reaches the more alkaline environment of the small intestine, which may reduce gastric irritation.
## Primary Indications
* Cardiovascular risk reduction (secondary prevention of myocardial infarction and stroke)
* Pain and inflammation (though lower doses are typically used for cardiovascular prophylaxis)
## Adult Dosing
* **Cardiovascular Prophylaxis:** Common doses range from 75 mg to 162 mg once daily. For secondary prevention after an acute coronary syndrome, doses of 75-162 mg once daily are typical.
* **Pain/Inflammation:** Doses vary widely and are typically higher than those used for cardiovascular prophylaxis. Common doses range from 325 mg to 650 mg every 4-6 hours as needed. Maximum daily dose should not exceed 4000 mg.
Dosing for specific indications may vary based on local protocols and patient-specific factors.
## Pediatric Dosing
Aspirin is generally **not recommended** in children and adolescents for viral infections due to the risk of Reye's syndrome. Specific indications and dosing for pediatric use (e.g., Kawasaki disease) should be determined by a specialist and based on established guidelines, which often involve higher doses initially followed by lower maintenance doses.
## Dose Adjustments
No specific dose adjustments are typically required for renal or hepatic impairment, but caution is advised, especially in severe impairment. Elderly patients may be more susceptible to adverse effects.
## Contraindications
* Known hypersensitivity to aspirin, NSAIDs, or salicylates.
* Asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.
* Active peptic ulceration or gastrointestinal bleeding.
* Children and teenagers with viral infections (risk of Reye's syndrome).
* Hemophilia or other bleeding disorders.
## Adverse Effects
The most common adverse effects include gastrointestinal upset, heartburn, nausea, vomiting, and dyspepsia. More serious adverse effects include:
* **Gastrointestinal:** Gastric or duodenal ulcers, bleeding, perforation.
* **Hemorrhagic:** Increased bleeding time, bruising, epistaxis, and potentially severe bleeding.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Auditory:** Tinnitus (especially at higher doses).
* **Renal:** Renal dysfunction.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of GI bleeding and renal dysfunction.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** NSAIDs may reduce their efficacy and increase the risk of renal dysfunction.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Alcohol:** Increased risk of GI irritation and bleeding.
## Monitoring
* Signs and symptoms of gastrointestinal bleeding (e.g., melena, hematemesis, abdominal pain).
* Signs and symptoms of bleeding elsewhere (e.g., bruising, prolonged bleeding from cuts).
* Renal function (especially in patients with pre-existing renal disease or those taking other nephrotoxic agents).
* Tinnitus may indicate toxicity.
## Clinical Pearls
* The enteric coating is intended to protect the stomach lining but does not eliminate the risk of GI bleeding or ulceration entirely.
* Aspirin should be taken with food or milk if GI upset occurs, although this may not prevent ulceration.
* Discontinue aspirin at least 5-7 days before elective surgery.
* For acute cardiovascular events, immediate-release aspirin (e.g., 325 mg, chewed) is often preferred for faster absorption and antiplatelet effect.
