## Overview
Ecospirin is an enteric-coated aspirin product. Aspirin is a nonsteroidal 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
* Pain relief (mild to moderate)
* Fever reduction
* Inflammation reduction
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in specific patient populations (secondary prevention)
* Prevention of preeclampsia in pregnant individuals at high risk
## Adult Dosing
* **Analgesia/Antipyresis:** 325 mg to 650 mg orally every 4 to 6 hours as needed. Maximum dose: 4000 mg/day.
* **Antiplatelet (Cardiovascular Prevention):** Typically 81 mg to 325 mg orally once daily. Dosing for secondary prevention is often determined by cardiologist.
* **Preeclampsia Prevention:** 60 mg to 100 mg orally once daily, typically initiated between 12 and 16 weeks gestation and continued until delivery.
## Pediatric Dosing
* **Analgesia/Antipyresis:** Due to the risk of Reye's syndrome, aspirin is generally **not recommended** for use in children and teenagers with viral infections or flu-like symptoms. If indicated for other reasons, dosing is weight-based. A common starting dose is 10-15 mg/kg/dose orally every 4-6 hours. Consult specific pediatric guidelines for precise dosing and indications.
## Dose Adjustments
* **Hepatic Impairment:** Use with caution. Dosing adjustments are not typically specified, but reduced doses may be considered due to impaired metabolism.
* **Renal Impairment:** Use with caution, especially in severe renal impairment. Prolonged use can lead to renal damage. Dosing adjustments may be necessary.
* **Elderly:** Elderly patients may be more susceptible to the adverse effects of aspirin, particularly gastrointestinal bleeding. Lower doses and increased monitoring may be warranted.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* Asthma, urticaria, or other allergic-type reactions to aspirin or other NSAIDs.
* Active peptic ulcer disease.
* Bleeding disorders (e.g., hemophilia, von Willebrand disease).
* Severe hepatic or renal impairment.
* Children and teenagers with viral infections (risk of Reye's syndrome).
* Third trimester of pregnancy (increased risk of premature closure of the ductus arteriosus).
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, heartburn, gastritis, peptic ulceration, gastrointestinal bleeding.
* **Hematologic:** Increased bleeding time, ecchymosis, epistaxis, purpura.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema, rash.
* **Ototoxicity:** Tinnitus, hearing loss (more common with higher doses).
* **Renal:** Acute kidney injury, interstitial nephritis.
* **Hepatic:** Elevated liver enzymes, hepatotoxicity.
* **Reye's Syndrome:** In children and adolescents with viral illness.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and Salicylates:** Increased risk of GI toxicity, bleeding, and impaired aspirin's antiplatelet effect.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics, beta-blockers):** Aspirin can reduce the efficacy of these agents.
* **Methotrexate:** Aspirin can displace methotrexate from plasma protein binding sites, increasing methotrexate toxicity.
* **Sulfonylureas:** Aspirin can potentiate hypoglycemia.
* **Uricosuric agents (e.g., probenecid):** Aspirin can inhibit the uricosuric effect.
* **Alcohol:** Increased risk of gastrointestinal bleeding.
## Monitoring
* **Signs and symptoms of gastrointestinal bleeding:** Melena, hematemesis, abdominal pain.
* **Signs and symptoms of increased bleeding:** Bruising, epistaxis, prolonged bleeding from cuts.
* **Renal and hepatic function:** Especially with long-term use or in patients with pre-existing impairment.
* **Tinnitus or hearing changes:** May indicate salicylism.
* **Blood pressure:** Especially if used for cardiovascular prevention.
## Clinical Pearls
* The enteric coating of Ecospirin is designed to be swallowed whole and not crushed or chewed to maintain its protective effect.
* Aspirin is a potent antiplatelet agent. Use with caution in patients undergoing surgery or with bleeding disorders.
* For cardiovascular prevention, low-dose aspirin (e.g., 81 mg) is typically used.
* In patients with a history of peptic ulcer disease or GI bleeding, the benefit of aspirin therapy must be carefully weighed against the risk of GI complications. Concomitant use of a proton pump inhibitor (PPI) may be considered.
* The risk of Reye's syndrome is a significant concern, and aspirin should be avoided in children and adolescents with viral illnesses.
