# 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 delay the release of aspirin until it reaches the small intestine, which may reduce gastric irritation.
## Primary Indications
* **Cardiovascular prophylaxis:** To reduce the risk of myocardial infarction, stroke, and cardiovascular death in patients with established cardiovascular disease or at high risk.
* **Pain and inflammation:** For the relief of mild to moderate pain and inflammation.
## Adult Dosing
* **Cardiovascular prophylaxis:**
* **Secondary prevention:** Typically 75 mg to 150 mg once daily. Higher doses (e.g., 325 mg daily) may be used for specific indications, but lower doses are generally preferred for long-term use to minimize bleeding risk.
* **Primary prevention:** Dosing varies depending on risk assessment and local guidelines. A common dose is 75 mg to 100 mg once daily or every other day.
* **Pain and inflammation:**
* **Mild to moderate pain:** 325 mg to 650 mg every 4 hours as needed, or 500 mg to 1000 mg every 4 to 6 hours as needed.
* **Maximum dose:** Generally 4000 mg per day, but lower doses are often sufficient and safer. Doses for specific inflammatory conditions may be higher and should be guided by specialist recommendations.
## Pediatric Dosing
Aspirin is generally **not recommended** for use in children and adolescents under 19 years of age due to the risk of Reye's syndrome, particularly when associated with viral illnesses such as influenza or varicella. In specific, rare circumstances, a physician may prescribe aspirin for conditions like Kawasaki disease, with careful monitoring and dose adjustments. Pediatric dosing for such indications is highly specific and determined by the treating physician.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment, but caution is advised due to potential for toxicity. Patients with severe renal or hepatic disease should be monitored closely.
## Contraindications
* Known hypersensitivity to aspirin, NSAIDs, or salicylates.
* History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs.
* Active peptic ulceration or gastrointestinal bleeding.
* Hemorrhagic disorders.
* Severe hepatic or renal impairment.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Use in the third trimester of pregnancy.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, peptic ulceration, GI bleeding.
* **Hematologic:** Increased bleeding time, bruising, petechiae, epistaxis, prolonged bleeding from wounds.
* **Hypersensitivity:** Bronchospasm, rhinitis, urticaria, angioedema.
* **Ototoxicity:** Tinnitus, hearing loss (typically with higher doses).
* **Renal:** Acute kidney injury, interstitial nephritis.
* **Hepatic:** Elevated liver enzymes, liver damage (rare).
* **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 and COX-2 inhibitors:** Increased risk of gastrointestinal bleeding and renal toxicity.
* **Corticosteroids:** Increased risk of gastrointestinal ulceration and bleeding.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Alcohol:** Increased risk of gastrointestinal irritation and bleeding.
* **Methotrexate:** May increase methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** May decrease antihypertensive efficacy and increase risk of renal impairment.
* **Uricosuric agents (e.g., probenecid):** May decrease the efficacy of uricosuric agents.
## Monitoring
* **Bleeding:** Monitor for signs of bleeding (e.g., melena, hematemesis, bruising, prolonged bleeding).
* **Gastrointestinal symptoms:** Assess for dyspepsia, abdominal pain, or other signs of GI distress.
* **Renal and hepatic function:** Periodically, especially in patients with pre-existing renal or hepatic disease or those on long-term, high-dose therapy.
* **Tinnitus or hearing changes:** May indicate salicylism.
## Clinical Pearls
* The enteric coating helps to reduce direct gastric irritation, but systemic absorption and the risk of bleeding remain.
* For acute pain relief, immediate-release aspirin may provide faster onset of action.
* Aspirin should be taken with food or a full glass of water to minimize gastrointestinal upset.
* Discontinue aspirin at least 5-7 days before elective surgery.
* If aspirin is used for cardiovascular protection, adherence to the prescribed dose is crucial. Do not stop or change dose without consulting a healthcare provider.
* The risk of Reye's syndrome is a critical consideration, and aspirin should be avoided in children and adolescents with viral illnesses.
