# Ecospirin (Aspirin, Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) and antiplatelet agent. The enteric coating is designed to delay absorption and reduce gastrointestinal irritation.
## Primary Indications
* **Cardiovascular Prevention:** Primary and secondary prevention of cardiovascular events (e.g., myocardial infarction, stroke) in at-risk individuals.
* **Pain and Inflammation:** Mild to moderate pain, fever, and inflammatory conditions (though less commonly used for this purpose than other NSAIDs due to its antiplatelet effects).
## Adult Dosing
* **Cardiovascular Prevention:**
* **Primary Prevention:** Typically 75-325 mg once daily. The decision to initiate aspirin for primary prevention should be individualized based on cardiovascular risk factors and bleeding risk.
* **Secondary Prevention:** Typically 75-325 mg once daily. Higher doses (e.g., 325 mg) may be used initially in acute cardiovascular events, then reduced to a lower maintenance dose.
* **Pain and Inflammation (less common):** 325-650 mg every 4-6 hours as needed, not to exceed 4000 mg per day.
Dosing for specific cardiovascular indications may vary based on clinical guidelines and physician preference.
## Pediatric Dosing
Aspirin is generally **contraindicated** in children and adolescents with viral infections due to the risk of Reye's syndrome. There are limited established pediatric indications for aspirin. Refer to specific guidelines for rare exceptions.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment, but caution is advised, especially with higher doses or prolonged use. Aspirin should be used with extreme caution or avoided in patients with severe renal or hepatic insufficiency.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* Active peptic ulceration or gastrointestinal bleeding.
* Asthma, urticaria, or other allergic-type reactions after taking NSAIDs or salicylates.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Hemophilia or other bleeding disorders.
* Severe hepatic or renal impairment.
* Third trimester of pregnancy.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, occult bleeding, peptic ulceration, GI perforation.
* **Bleeding:** Increased risk of bleeding (e.g., bruising, epistaxis, surgical bleeding, GI hemorrhage, intracranial hemorrhage).
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Auditory:** Tinnitus, hearing loss (often dose-related).
* **Renal:** Renal insufficiency, interstitial nephritis.
* **Hepatic:** Hepatotoxicity.
* **Reye's Syndrome:** In children and adolescents with viral illnesses.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and Salicylates:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Alcohol:** Increased risk of GI bleeding.
* **Methotrexate:** Increased methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** Reduced antihypertensive efficacy.
* **Uricosuric agents (e.g., probenecid):** Reduced uricosuric effect.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** May increase bleeding risk.
## Monitoring
* **Bleeding:** Monitor for signs and symptoms of bleeding (e.g., bruising, black tarry stools, hematemesis).
* **GI Symptoms:** Assess for gastrointestinal discomfort or pain.
* **Renal Function:** Monitor renal function, especially in patients with pre-existing renal disease or those on long-term therapy.
* **Hepatic Function:** Monitor hepatic function if clinically indicated.
* **Auditory Symptoms:** Assess for tinnitus.
## Clinical Pearls
* The enteric coating allows aspirin to pass through the stomach largely intact, releasing in the small intestine, which can reduce gastric irritation compared to non-enteric coated aspirin. However, GI adverse effects can still occur.
* For daily low-dose therapy (e.g., cardiovascular protection), the benefits typically outweigh the risks in appropriate patients.
* Avoid concurrent use with other NSAIDs unless specifically indicated and managed by a healthcare professional.
* Instruct patients to report any signs of bleeding or severe gastrointestinal distress immediately.
* Aspirin should be discontinued several days before elective surgery to minimize bleeding risk. The exact duration depends on the type of surgery and individual patient factors.
