## Ecospirin (Aspirin Enteric-Coated)
### Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory, and antipyretic properties. The enteric coating is designed to prevent gastric irritation by delaying the release of aspirin until it reaches the small intestine.
### Primary Indications
* Pain relief (mild to moderate)
* Inflammation reduction
* Fever reduction
* Cardiovascular protection (e.g., prevention of myocardial infarction, stroke)
### Adult Dosing
Dosing varies significantly based on indication:
* **Analgesic/Antipyretic/Anti-inflammatory:** 325 mg to 650 mg every 4 to 6 hours as needed. Maximum dose typically 4000 mg per day.
* **Cardiovascular Prevention (Secondary Prevention):** 75 mg to 100 mg once daily.
* **Cardiovascular Prevention (Primary Prevention):** 75 mg to 100 mg once daily (decision based on individual risk assessment and discussion with a healthcare provider).
* **Kawasaki Disease:** Dosing is weight-based and varies during the acute phase and convalescent phase. Acute phase: 80-100 mg/kg/day divided into 4 doses. Convalescent phase: 3-5 mg/kg/day once daily. **Consult specific guidelines for precise dosing.**
### Pediatric Dosing
* **Pain/Fever:** Dosing is weight-based, typically 10-15 mg/kg/dose every 4-6 hours. Maximum dose 650 mg/dose. **Aspirin is generally NOT recommended for children and adolescents under 19 years of age due to the risk of Reye's syndrome, especially during viral illnesses.** Exceptions include specific indications like Kawasaki disease and juvenile idiopathic arthritis under strict medical supervision.
* **Kawasaki Disease:** As per adult dosing above.
### Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe renal impairment.
* **Hepatic Impairment:** Use with caution. Monitor liver function.
### Contraindications
* Hypersensitivity to aspirin, NSAIDs, or salicylates.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Active peptic ulcer disease.
* Bleeding disorders.
* Severe renal or hepatic impairment.
* Late pregnancy (third trimester).
### Adverse Effects
* Gastrointestinal: Dyspepsia, nausea, vomiting, abdominal pain, GI bleeding, ulceration.
* Hematologic: Increased bleeding time, bruising, epistaxis.
* Hypersensitivity: Bronchospasm (especially in aspirin-sensitive asthma), urticaria, angioedema.
* Tinnitus and hearing loss (salicylism).
* Reye's syndrome (in children/adolescents with viral infections).
### 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.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** Aspirin can reduce their efficacy and increase the risk of renal toxicity.
* **Methotrexate:** Increased methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Reduced uricosuric effect.
* **Alcohol:** Increased risk of GI bleeding.
### Monitoring
* Signs and symptoms of GI bleeding (melena, hematemesis, abdominal pain).
* Signs and symptoms of bleeding or bruising.
* Renal function (especially with long-term use or in high-risk patients).
* Liver function (especially with long-term use or in patients with hepatic impairment).
* Tinnitus or hearing changes (may indicate salicylism).
### Clinical Pearls
* The enteric coating helps reduce gastric upset 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.
* Avoid concurrent use with other NSAIDs unless specifically advised by a healthcare provider.
* Inform patients about the risk of Reye's syndrome and to avoid aspirin in children and adolescents with viral illnesses.
* Low-dose aspirin for cardiovascular prevention should be initiated and managed by a healthcare provider based on individual risk assessment.
