# Aspirin 250 mg Enteric-Coated
## Overview
Ecospirin 250 mg is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with antiplatelet, analgesic, and antipyretic properties. The enteric coating is designed to delay absorption until the drug reaches the small intestine, reducing gastric irritation.
## Primary Indications
* **Cardiovascular Prophylaxis:** Prevention of myocardial infarction and stroke in patients with established cardiovascular disease or risk factors.
* **Pain and Inflammation:** Management of mild to moderate pain and inflammatory conditions.
* **Fever Reduction:** Management of fever.
## Adult Dosing
* **Cardiovascular Prophylaxis:** Typically 75 mg to 325 mg once daily. For secondary prevention, doses of 325 mg once daily are often used initially.
* **Pain and Inflammation:** 325 mg to 650 mg every 4 hours as needed, or 1000 mg every 6-8 hours as needed.
* **Fever Reduction:** 325 mg to 650 mg every 4 hours as needed.
* **Maximum Daily Dose:** Generally not to exceed 4000 mg per day for anti-inflammatory effects. For cardiovascular prophylaxis, the dose is typically much lower.
*Note: The specific dose for cardiovascular prophylaxis may vary based on patient risk and local guidelines.*
## Pediatric Dosing
* **General Use:** Aspirin is generally **not recommended** for use in children and teenagers due to the risk of Reye's syndrome, particularly when associated with viral illnesses like influenza or chickenpox.
* **Specific Indications:** In rare situations, and under strict medical supervision, aspirin may be considered for specific conditions in children, such as Kawasaki disease or certain rheumatologic conditions. Dosing is highly individualized and weight-based, requiring expert consultation.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Doses may need to be reduced in severe renal impairment.
* **Hepatic Impairment:** Use with caution. Doses may need to be reduced in severe hepatic impairment.
* **Elderly:** Elderly patients may be more susceptible to adverse effects, particularly gastrointestinal bleeding. Lower doses and careful monitoring are recommended.
## Contraindications
* Hypersensitivity to aspirin, salicylates, or NSAIDs.
* Active peptic ulceration or history of gastrointestinal bleeding.
* Bleeding disorders.
* Severe hepatic or renal impairment.
* Asthma, urticaria, or other allergic-type reactions to aspirin or other NSAIDs.
* Children and teenagers with viral infections (risk of Reye's syndrome).
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, occult gastrointestinal bleeding, peptic ulceration, perforation.
* **Hematologic:** Increased bleeding time, bruising, epistaxis, prolonged prothrombin time.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Auditory:** Tinnitus, hearing loss (often reversible).
* **Renal:** Acute kidney injury, interstitial nephritis.
* **Hepatic:** Elevated liver enzymes, hepatitis.
* **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 gastrointestinal adverse effects and bleeding.
* **Corticosteroids:** Increased risk of gastrointestinal adverse effects.
* **Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs):** Increased risk of bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** May decrease their efficacy and increase the risk of kidney damage.
* **Uricosuric agents (e.g., probenecid):** Aspirin can interfere with their uricosuric effect.
* **Alcohol:** Increased risk of gastrointestinal bleeding.
## Monitoring
* **Gastrointestinal Symptoms:** Monitor for signs and symptoms of dyspepsia, abdominal pain, or occult bleeding.
* **Bleeding:** Monitor for signs of increased bleeding (e.g., bruising, epistaxis, prolonged bleeding from cuts).
* **Renal Function:** Monitor serum creatinine and BUN, especially in patients with risk factors for renal impairment.
* **Liver Function:** Monitor liver enzymes, especially with long-term or high-dose therapy.
* **Tinnitus/Hearing:** Assess for tinnitus or hearing loss, which may indicate excessive dosage.
## Clinical Pearls
* The enteric-coated formulation should not be crushed, chewed, or broken to ensure proper release in the small intestine and minimize gastric irritation.
* For acute antiplatelet effects or rapid pain relief, an immediate-release formulation may be preferred.
* Aspirin is often used in combination with other antiplatelet agents (e.g., clopidogrel) for secondary prevention of cardiovascular events; monitor closely for bleeding.
* Discontinue aspirin at least 5-7 days before elective surgery if the risk of bleeding outweighs the benefit of continued therapy.
* Ensure patients are aware of the risk of Reye's syndrome and avoid aspirin in children and adolescents with febrile illnesses.
