## Ecospirin (Aspirin, Enteric-Coated)
### Overview
Ecospirin is an enteric-coated formulation of aspirin, a non-steroidal anti-inflammatory drug (NSAID) and antiplatelet agent. The enteric coating is designed to delay release of aspirin until it reaches the small intestine, potentially reducing gastric irritation.
### Primary Indications
* **Cardiovascular Risk Reduction:** Prevention of recurrent myocardial infarction, stroke, and cardiovascular death in patients with established cardiovascular disease.
* **Secondary Prevention:** In patients with transient ischemic attack (TIA) or ischemic stroke.
* **Adjunctive Therapy:** With coronary artery bypass grafting (CABG) or percutaneous transluminal coronary angioplasty (PTCA).
### Adult Dosing
* **Cardiovascular Prophylaxis/Secondary Prevention:** Typically 75 mg to 325 mg once daily. Dosing may vary based on indication and clinical guidelines. For example, post-MI or post-stroke, 75-162 mg daily is common. After stenting or PTCA, doses may be higher initially (e.g., 162-325 mg twice daily) before transitioning to a lower maintenance dose. Specific dosing for these indications often depends on local protocols and current guidelines.
### Pediatric Dosing
* **Kawasaki Disease:** Dosing varies significantly based on the phase of illness. Acute phase: 30-50 mg/kg/day divided into 2-4 doses. After fever resolution: 3-5 mg/kg/day once daily. Dosing should be guided by specific pediatric cardiology protocols.
* **Other Indications:** Aspirin is generally **not recommended** in children and adolescents with viral infections (e.g., influenza, varicella) due to the risk of Reye's syndrome.
### Dose Adjustments
* **Hepatic Impairment:** Use with caution. Dose adjustments are not well-defined, but consider reduced efficacy or increased risk of bleeding.
* **Renal Impairment:** Use with caution, especially in severe impairment. Monitor for adverse effects.
### Contraindications
* Known hypersensitivity to aspirin, NSAIDs, or salicylates.
* Children or teenagers with viral infections (risk of Reye's syndrome).
* Active peptic ulceration or history of recurrent gastrointestinal (GI) bleeding.
* Severe hepatic impairment.
* Severe renal impairment.
* Hemorrhagic diathesis or conditions associated with bleeding.
* Late pregnancy (third trimester).
### Adverse Effects
* **Common:** Dyspepsia, heartburn, nausea, abdominal pain.
* **Serious:** GI bleeding, ulceration, perforation, tinnitus, hearing loss, hypersensitivity reactions (including bronchospasm, urticaria, angioedema), bruising, prolonged bleeding time, Reye's syndrome (in children/adolescents with viral infections).
### Key Drug Interactions
* **Anticoagulants (e.g., warfarin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs/COX-2 Inhibitors:** Additive risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** Reduced antihypertensive efficacy.
* **Methotrexate:** Increased methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Reduced uricosuric effect.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
### Monitoring
* **Signs of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Signs of bleeding elsewhere:** Easy bruising, epistaxis, prolonged bleeding from cuts.
* **Tinnitus or hearing changes:** May indicate toxicity.
* **Renal and hepatic function:** Especially in patients with pre-existing impairment or those on long-term therapy.
### Clinical Pearls
* The enteric coating does not eliminate the risk of GI bleeding or ulceration, although it may reduce the frequency compared to non-coated aspirin.
* Crushing or chewing enteric-coated tablets will destroy the coating and should be avoided.
* Dosing for cardiovascular indications should align with current evidence-based guidelines (e.g., ACC/AHA, ESC).
* For patients requiring urgent antiplatelet therapy, immediate-release aspirin is often preferred.
