# Ecospirin Enteric-Coated (Aspirin)
## Overview
Ecospirin is a brand name for aspirin (acetylsalicylic acid), a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory, and antipyretic properties. The enteric coating is designed to delay the release of aspirin until it reaches the small intestine, potentially reducing gastric irritation.
## Primary Indications
* Pain relief (mild to moderate)
* Fever reduction
* Inflammation reduction
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in certain patient populations (antiplatelet therapy)
## Adult Dosing
Dosing varies significantly based on indication.
* **Pain/Fever/Inflammation:**
* Typical dose: 325 mg to 650 mg orally every 4 to 6 hours as needed.
* Maximum dose: Generally not to exceed 4000 mg per 24 hours for anti-inflammatory effects, though lower for routine pain/fever.
* **Cardiovascular Prevention (Antiplatelet):**
* Common dose: 81 mg to 325 mg orally once daily. Lower doses (e.g., 81 mg) are frequently used for long-term prevention.
## Pediatric Dosing
**Aspirin is generally not recommended for children and teenagers with viral infections due to the risk of Reye's syndrome.** If aspirin is absolutely indicated in a pediatric patient (e.g., Kawasaki disease), dosing is typically based on weight and indication.
* **Kawasaki Disease (Consult specific guidelines/pediatric rheumatology):** Dosing varies based on the phase of illness (acute vs. maintenance) and may range from 30-100 mg/kg/day divided into doses.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe impairment. Aspirin is removed by dialysis.
* **Hepatic Impairment:** Use with caution. Monitor liver function.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.
* Children and teenagers with viral infections (risk of Reye's syndrome).
* Active peptic ulcer disease or gastrointestinal bleeding.
* Bleeding disorders.
* Severe renal or hepatic impairment.
* Third trimester of pregnancy.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, peptic ulceration, GI bleeding.
* **Hematologic:** Increased bleeding time, bruising, epistaxis.
* **Hypersensitivity:** Bronchospasm (especially in aspirin-sensitive asthmatics), urticaria, angioedema.
* **Auditory:** Tinnitus, hearing loss (especially at higher doses).
* **Renal:** Analgesic nephropathy (with chronic high-dose use).
* **Hepatic:** Liver enzyme elevations.
* **Reye's Syndrome:** In children and teenagers 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, beta-blockers):** Aspirin may reduce their efficacy.
* **Methotrexate:** Aspirin can decrease methotrexate clearance, increasing toxicity.
* **Uricosuric agents (e.g., probenecid):** Aspirin antagonizes the uricosuric effect.
* **Valproic acid:** Aspirin can displace valproic acid from plasma protein binding sites, increasing free valproic acid levels.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
## Monitoring
* **GI Bleeding:** Monitor for signs and symptoms (melena, hematemesis, abdominal pain).
* **Bleeding:** Monitor for bruising, prolonged bleeding from cuts, epistaxis.
* **Renal Function:** Especially in patients with pre-existing renal disease or those on long-term therapy.
* **Hepatic Function:** May be necessary in patients with liver disease or on long-term therapy.
* **Tinnitus/Hearing:** Assess for auditory changes, particularly with higher doses.
## Clinical Pearls
* The enteric coating reduces but does not eliminate the risk of GI side effects. Take with food or milk if gastric upset occurs, unless contraindicated.
* Do not crush or chew enteric-coated tablets.
* Due to the risk of Reye's syndrome, aspirin should be avoided in children and adolescents unless specifically directed by a healthcare professional for a particular condition (e.g., Kawasaki disease).
* For antiplatelet therapy, consistency is key. Advise patients to take their daily dose at the same time each day.
* Patients taking aspirin for cardiovascular prevention should discuss all other medications, including OTC products and herbal supplements, with their healthcare provider due to potential interactions.
