# 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 absorption until the drug reaches the small intestine, which may reduce gastric irritation.
## Primary Indications
* **Cardiovascular risk reduction:** Prevention of myocardial infarction and stroke in patients with established cardiovascular disease or at high risk.
* **Pain and fever:** Relief of mild to moderate pain and reduction of fever.
* **Inflammation:** Management of inflammatory conditions (less common use for enteric-coated aspirin due to slower onset of action).
## Adult Dosing
* **Cardiovascular prophylaxis:**
* 75 mg to 325 mg once daily. Doses are typically low (e.g., 81 mg or 100 mg) for long-term prevention. Higher doses (e.g., 325 mg) may be used acutely following certain cardiovascular events as per specific guidelines.
* **Pain and fever:**
* 325 mg to 650 mg every 4 to 6 hours as needed.
* Maximum daily dose: 4000 mg.
Dosing for specific indications (e.g., post-PCI, ACS) should follow established clinical guidelines.
## Pediatric Dosing
Aspirin is generally **not recommended** for children and teenagers due to the risk of Reye's syndrome, especially with viral illnesses.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Severe renal impairment may warrant dose reduction or discontinuation.
* **Hepatic Impairment:** Use with caution.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of asthma, urticaria, or allergic-type reactions after taking aspirin or NSAIDs.
* Children and teenagers with viral infections (risk of Reye's syndrome).
* Active peptic ulcer disease or gastrointestinal bleeding.
* Severe renal or hepatic impairment.
* Hemophilia, thrombasthenia, or other bleeding disorders.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, abdominal pain, gastritis, peptic ulceration, GI bleeding.
* **Hemorrhage:** Increased bleeding risk, epistaxis, bruising.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Auditory:** Tinnitus, hearing loss (more common with higher doses or overdose).
* **Renal:** Renal insufficiency (rare with low-dose aspirin).
* **Hepatic:** Elevated liver enzymes (rare).
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives:** May reduce the efficacy of some antihypertensives.
* **Methotrexate:** May increase methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Aspirin may decrease their efficacy.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Alcohol:** Increased risk of GI irritation and bleeding.
## Monitoring
* Signs and symptoms of GI bleeding (melena, hematemesis, abdominal pain).
* Signs and symptoms 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 is designed to dissolve in the higher pH of the small intestine, but absorption can still occur in the stomach if the coating fails or dissolves prematurely (e.g., with concurrent use of antacids or in situations of delayed gastric emptying).
* For acute antiplatelet therapy (e.g., after ACS or PCI), non-enteric-coated aspirin is often preferred for faster absorption.
* Patients taking low-dose aspirin for cardiovascular protection should generally not discontinue it without consulting their healthcare provider, even before surgery, unless specifically advised. The risk of thrombotic events may outweigh the bleeding risk in many cases.
