์์ฉ ๊ธฐ์ : Ramipril is a pro-drug with minimal intrinsic pharmacologic activity. Upon absorption, it undergoes hepatic de-esterification โ **ramiprilat** (the active metabolite). * Ramiprilat competitively binds to **Angiotensin-Converting Enzyme (ACE)**, preventing the conversion of **Angiotensin I** โ **Angiotensin II**. * Because Angiotensin II is a potent vasoconstrictor, its reduction leads to **vasodilation** (decreased total peripheral and pulmonary vascular resistance). * Decreased Angiotensin II also reduces **aldosterone** secretion โ decreased sodium and water retention, and increased plasma renin activity. * **Renal effects:** ACE inhibitors preferentially dilate the efferent arteriole of the glomerulus โ decreased intraglomerular pressure โ reduced proteinuria.

- Aspirin ยท May potentially negate the decrease in systemic vascular resistance induced by ACE inhibitors (though low-dose aspirin did not affect enalaprilat hemodynamics in one dog study).
- Antidiabetic agents (insulin, oral agents) ยท Possible increased risk for hypoglycemia; enhanced monitoring recommended.
- Diuretics (e.g., furosemide, hydrochlorothiazide) ยท Potential for increased hypotensive effects.
- Diuretics, potassium sparing (e.g., spironolactone, triamterene) ยท Increased hyperkalemic effects; enhanced monitoring of serum potassium required.
- NSAIDs ยท Potential for increased risk of renal dysfunction or hyperkalemia.
- Potassium supplements ยท Increased risk for hyperkalemia.

Ramipril appears quite safe in dogs; dosages as high as 1 gram/kg induced only mild GI distress. Lethal doses in rodents are extremely high (10-11 grams/kg). * **Primary concern:** Hypotension. * **Treatment:** Supportive treatment with volume expansion (normal saline) is recommended to correct blood pressure. * **Note:** Because of the drug's long duration of action, prolonged monitoring and treatment may be required.
