## Ecospirin (Aspirin) Enteric-Coated
### Overview
Ecospirin is an enteric-coated formulation of aspirin, a non-steroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, and antiplatelet properties. The enteric coating is designed to prevent dissolution in the stomach, reducing the risk of gastric irritation.
### Primary Indications
* **Cardiovascular prophylaxis:** Prevention of myocardial infarction (MI) and stroke in patients with established cardiovascular disease or risk factors.
* **Analgesia and antipyresis:** Mild to moderate pain and fever.
### Adult Dosing
* **Cardiovascular prophylaxis:**
* Typical dose: 75-162 mg orally once daily. Some protocols may use up to 325 mg daily.
* Maximum dose for cardiovascular prophylaxis is generally not defined but adherence to lower doses is preferred.
* **Analgesia and antipyresis:**
* Typical dose: 325-650 mg orally every 4-6 hours as needed.
* Maximum dose: 4000 mg orally per day.
Dosing for specific indications such as rheumatologic conditions may differ and should follow established guidelines or local protocols.
### Pediatric Dosing
Aspirin is generally **not recommended** in children and adolescents under 19 years of age for fever or pain due to the risk of Reye's syndrome, especially during viral illnesses. Specific indications, such as Kawasaki disease, have established pediatric dosing regimens that require careful medical supervision.
### Dose Adjustments
No specific dose adjustments are routinely required for renal or hepatic impairment, but caution is advised. Monitor for signs of toxicity, especially in patients with severe impairment.
### Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* History of aspirin-induced asthma, urticaria, or other allergic-type reactions.
* Active peptic ulceration or gastrointestinal bleeding.
* Bleeding disorders (e.g., hemophilia, thrombocytopenia).
* Severe hepatic or renal impairment.
* Last trimester of pregnancy.
### Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, GI bleeding, ulceration.
* **Hematologic:** Increased bleeding time, bruising, epistaxis, menorrhagia.
* **Hypersensitivity:** Bronchospasm (aspirin-exacerbated respiratory disease), rash, urticaria.
* **Other:** Tinnitus (especially with higher doses), dizziness, headache.
* **Reye's Syndrome:** In children and adolescents with viral infections.
### Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs:** Additive GI toxicity and increased risk of bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Methotrexate:** Increased methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** Reduced antihypertensive efficacy.
* **Uricosuric agents (e.g., probenecid):** Decreased uricosuric effect.
### Monitoring
* Signs and symptoms of GI bleeding (melena, hematemesis, abdominal pain).
* Signs of bleeding or bruising.
* Renal function, especially in patients with pre-existing renal disease or those taking other nephrotoxic agents.
* Tinnitus or hearing changes may indicate toxicity.
### Clinical Pearls
* The enteric coating allows aspirin to bypass the stomach and dissolve in the more alkaline small intestine, which may reduce gastric irritation compared to non-coated aspirin. However, GI adverse effects can still occur.
* Patients should be advised not to crush, chew, or break the enteric-coated tablets.
* Discontinue aspirin at least 5-7 days prior to elective surgery.
* Consider the risk of Reye's syndrome when prescribing to pediatric patients.
