# 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 prevent dissolution in the stomach, reducing gastric irritation and allowing for absorption in the small intestine.
## Primary Indications
* Pain relief (mild to moderate)
* Fever reduction
* Inflammation reduction
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in select patient populations
* Prevention of pre-eclampsia
## Adult Dosing
Dosing varies significantly based on indication. Always refer to specific guidelines or protocols.
* **Analgesic/Antipyretic:** 325 mg to 1000 mg every 4 to 6 hours as needed. Maximum daily dose typically 4000 mg.
* **Cardiovascular Prevention (Primary/Secondary):** 75 mg to 325 mg once daily. Doses for secondary prevention are often higher (e.g., 325 mg daily).
* **Prevention of Pre-eclampsia:** 75 mg to 100 mg once daily, typically initiated between 12 and 16 weeks of gestation.
## Pediatric Dosing
Aspirin is generally **contraindicated** in children and adolescents for fever and viral illnesses due to the risk of Reye's syndrome.
* When used for specific indications (e.g., Kawasaki disease treatment), dosing is highly specialized and guided by expert consensus or specific protocols. Doses are often weight-based and can be high. **Consult pediatric infectious disease or rheumatology guidelines.**
## Dose Adjustments
* **Renal Impairment:** Use with caution. High doses may require dose adjustment in severe renal impairment.
* **Hepatic Impairment:** Use with caution.
## Contraindications
* Hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Active gastrointestinal bleeding or history of peptic ulcer disease.
* Asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Third trimester of pregnancy (risk of premature closure of the ductus arteriosus, pulmonary hypertension).
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, GI bleeding, ulceration.
* **Hematologic:** Increased bleeding time, bruising, petechiae.
* **Respiratory:** Bronchospasm (especially in aspirin-sensitive asthmatics).
* **Renal:** Renal dysfunction (particularly with high doses or in susceptible individuals).
* **Other:** Tinnitus, hearing loss (with high doses), hypersensitivity reactions.
## 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.
* **Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs):** Increased risk of bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Aspirin can decrease their efficacy.
* **Oral hypoglycemics:** May potentiate hypoglycemic effects.
* **Valproic acid:** Aspirin can displace valproic acid from plasma protein binding, increasing free levels.
## Monitoring
* **Signs and symptoms of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Bleeding:** Easy bruising, prolonged bleeding from cuts, epistaxis.
* **Renal function:** BUN, creatinine, especially in patients with pre-existing renal disease or on concurrent nephrotoxic agents.
* **Liver function:** AST, ALT, especially with chronic use or high doses.
* **Tinnitus and hearing:** Can be signs of salicylism (toxicity).
## Clinical Pearls
* The enteric coating delays absorption and reduces gastric irritation but does not eliminate the risk of GI bleeding.
* Take with a full glass of water. Do not crush, chew, or break enteric-coated tablets.
* For cardiovascular protection, adherence to daily dosing is crucial.
* Discontinue aspirin at least 5-7 days before elective surgery.
* Aspirin toxicity (salicylism) can present with tinnitus, hearing loss, confusion, and hyperventilation.
