# 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 absorption and reduce gastric irritation.
## Primary Indications
* Pain and fever management (analgesic, antipyretic)
* Prevention of cardiovascular events (antiplatelet therapy)
* Management of inflammatory conditions (anti-inflammatory)
## Adult Dosing
Dosing is highly variable depending on the indication.
* **Pain and Fever:** Typical doses range from 325 mg to 650 mg every 4-6 hours as needed. Maximum daily dose is generally 4000 mg.
* **Cardiovascular Prevention (Secondary Prevention):** Doses often range from 75 mg to 325 mg once daily.
* **Cardiovascular Prevention (Primary Prevention):** Doses typically range from 75 mg to 100 mg once daily. Guidelines vary; consult current recommendations.
* **Inflammatory Conditions (e.g., Rheumatoid Arthritis):** Doses can range from 2600 mg to 5200 mg per day, divided into 4-6 doses. This is less common due to the availability of more targeted NSAIDs and the risk of aspirin toxicity at these higher doses.
## Pediatric Dosing
Aspirin is generally **not recommended** in children and adolescents (<19 years) for fever or viral illnesses due to the risk of Reye's syndrome. Specific indications and dosing for pediatric populations, if any, require careful consideration and specialist guidance.
## Dose Adjustments
* **Renal Impairment:** Use with caution. May require dose reduction, especially in severe renal impairment.
* **Hepatic Impairment:** Use with caution. May require dose reduction.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Active peptic ulcer disease or history of recurrent ulcers.
* Bleeding disorders (e.g., hemophilia, thrombocytopenia).
* Severe hepatic or renal impairment.
* Concurrent use with methotrexate at high doses (see interactions).
* Children and adolescents (<19 years) with viral infections.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, peptic ulceration, GI bleeding.
* **Hematologic:** Increased bleeding time, bruising, petechiae, epistaxis, prolonged bleeding from cuts. Rarely, severe hemorrhage.
* **Hypersensitivity:** Bronchospasm (especially in aspirin-sensitive asthma), urticaria, angioedema, rhinitis.
* **Tinnitus and hearing loss:** Can be signs of salicylism, especially at higher doses.
* **Reye's syndrome:** In children and adolescents with viral illnesses.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 inhibitors:** Increased risk of GI toxicity, reduced antiplatelet effect of aspirin.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **SSRIs/SNRIs:** Increased risk of bleeding, particularly GI bleeding.
* **Methotrexate:** Increased risk of methotrexate toxicity, especially at high-dose aspirin regimens. Monitor closely.
* **Uricosuric agents (e.g., probenecid):** Aspirin may decrease the efficacy of uricosuric agents.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** NSAIDs may reduce the antihypertensive effect and increase the risk of renal toxicity.
* **Alcohol:** Increased risk of GI irritation and bleeding.
## Monitoring
* **Signs of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Signs of bleeding:** Easy bruising, prolonged bleeding from wounds, epistaxis.
* **Renal function:** Especially in patients with pre-existing renal disease or those taking other nephrotoxic agents.
* **Hepatic function:** Especially in patients with pre-existing liver disease.
* **Tinnitus/hearing changes:** May indicate salicylism.
## Clinical Pearls
* The enteric coating allows aspirin to bypass the stomach and dissolve in the small intestine, reducing gastric irritation. However, it does not eliminate the risk of GI bleeding or ulceration, particularly with long-term or high-dose use.
* Patients should be advised to swallow the tablet whole and not to crush, chew, or break it.
* For acute cardiovascular event prevention, immediate-release aspirin is often preferred for faster onset of action, though enteric-coated formulations are commonly used for chronic therapy.
* Discontinue aspirin several days prior to elective surgery, as advised by the prescribing physician.
