# Ecospirin Enteric-Coated (Aspirin)
## Overview
Ecospirin Enteric-Coated is a brand name for aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory, and antipyretic properties. The enteric coating is designed to delay absorption until the drug reaches the small intestine, potentially reducing gastric irritation.
## Primary Indications
* Pain and inflammation (mild to moderate)
* Fever
* Cardiovascular risk reduction (e.g., prevention of myocardial infarction, stroke)
## Adult Dosing
Dosing varies widely depending on the indication.
* **Analgesic/Antipyretic:** 325 mg to 650 mg every 4 hours as needed. Maximum dose: 4000 mg per 24 hours.
* **Anti-inflammatory:** 2400 mg to 3600 mg per day divided into multiple doses.
* **Cardiovascular Prevention:** Typically 75 mg to 100 mg once daily. Higher doses (e.g., 325 mg daily) may be used in specific acute situations, but are generally not recommended for long-term primary prevention due to increased bleeding risk.
Dose for specific indications should follow established guidelines or local protocols.
## Pediatric Dosing
Aspirin is generally **not recommended** in children and teenagers due to the risk of Reye's syndrome, a rare but serious condition. Exceptions may exist for specific conditions like Kawasaki disease, where dosing is guided by expert consensus and specific protocols.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe renal impairment.
* **Hepatic Impairment:** Use with caution.
## Contraindications
* Hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of aspirin-induced asthma, urticaria, or other allergic-type reactions.
* Bleeding disorders (e.g., hemophilia, thrombocytopenia).
* Active peptic ulceration or gastrointestinal bleeding.
* In children and adolescents with viral infections (e.g., influenza, varicella) due to the risk of Reye's syndrome.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, occult GI bleeding, peptic ulceration, perforation.
* **Hematologic:** Increased bleeding time, bruising, petechiae, epistaxis, prolonged bleeding from cuts.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema, rhinitis.
* **Renal:** Renal insufficiency, interstitial nephritis.
* **Hepatic:** Elevated liver enzymes.
* **Other:** Tinnitus, dizziness, confusion.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of GI toxicity.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** Aspirin may reduce their antihypertensive effect.
* **Methotrexate:** Increased methotrexate toxicity.
* **Sulfonylureas:** Increased risk of hypoglycemia.
* **Uricosuric agents (e.g., probenecid):** Decreased efficacy of uricosuric agents.
* **Alcohol:** Increased risk of GI bleeding.
## Monitoring
* **GI Bleeding:** Monitor for signs and symptoms (e.g., melena, hematemesis, abdominal pain).
* **Bleeding:** Monitor for easy bruising, prolonged bleeding from minor cuts, epistaxis.
* **Renal Function:** Particularly in patients with pre-existing renal disease or those taking other nephrotoxic agents.
* **Hepatic Function:** If clinically indicated.
* **Tinnitus:** May indicate therapeutic toxicity.
## Clinical Pearls
* The enteric coating helps reduce gastric irritation but does not eliminate the risk of GI bleeding or ulceration, especially with long-term use or higher doses.
* Do not crush or chew enteric-coated tablets, as this will destroy the coating and can lead to premature drug release and increased gastric irritation.
* Advise patients to avoid alcohol while taking aspirin due to increased GI bleeding risk.
* For cardiovascular indications, adherence to the prescribed low dose is crucial.
