## 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 prevent dissolution in the stomach and release the medication in the small intestine, potentially reducing gastric irritation.
### Primary Indications
* Cardiovascular prophylaxis (e.g., prevention of myocardial infarction, stroke)
* Pain and fever management (less common due to availability of other NSAIDs with potentially better GI safety profiles)
* Inflammatory conditions (less common)
### Adult Dosing
* **Cardiovascular Prophylaxis:** Typically 75 mg to 100 mg once daily. Higher doses (e.g., 325 mg daily) may be used in specific situations, but lower doses are generally preferred for long-term use to minimize bleeding risk. The exact dose often depends on local guidelines and physician preference.
* **Pain and Fever:** Doses range from 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose generally 4000 mg.
### Pediatric Dosing
Aspirin is generally **not recommended** in children and adolescents for viral infections (including influenza and varicella) due to the risk of Reye's syndrome. Dosing for other indications in pediatrics is highly specialized and should be determined by a physician.
### Dose Adjustments
* **Renal Impairment:** Use with caution. Severe renal impairment may warrant dose reduction or avoidance.
* **Hepatic Impairment:** Use with caution.
* **Elderly:** Increased risk of gastrointestinal bleeding and other adverse effects; lower doses may be appropriate.
### Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of aspirin-induced asthma, urticaria, or other allergic-type reactions.
* Active peptic ulceration or gastrointestinal bleeding.
* Certain bleeding disorders.
* Children and adolescents with viral infections (risk of Reye's syndrome).
### Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, **gastric erosion, ulceration, and bleeding**.
* **Hematologic:** Increased bleeding time, bruising, petechiae, epistaxis, **hemorrhage**.
* **Hypersensitivity:** Bronchospasm, rhinitis, urticaria.
* **Other:** Tinnitus, dizziness, headache, nephrotoxicity (with chronic high-dose use).
### Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and Corticosteroids:** Increased risk of gastrointestinal bleeding.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Alcohol:** Increased risk of gastrointestinal irritation and bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Aspirin may decrease the efficacy of these agents.
### Monitoring
* **Signs and symptoms of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Signs and symptoms of bleeding:** Easy bruising, prolonged bleeding from cuts, epistaxis.
* **Renal function:** Particularly in patients with pre-existing renal disease or those on long-term therapy.
* **Auditory:** Tinnitus can be an early sign of salicylate toxicity.
### Clinical Pearls
* The enteric coating allows for delayed absorption and may reduce stomach upset, but it does not eliminate the risk of gastrointestinal bleeding, especially with regular use.
* Do not crush, chew, or break enteric-coated tablets.
* Patients with asthma, nasal polyps, and aspirin sensitivity are at higher risk of severe reactions.
* For acute pain or fever, other agents may be preferred in the general population due to a potentially better GI safety profile.
* For cardiovascular protection, low-dose aspirin is generally preferred.
