ethacrynic acid
Very LowTechnical/Medical
Definition
Meaning
A potent synthetic diuretic medication used to treat fluid retention.
A pharmacological agent, specifically a loop diuretic, that inhibits sodium reabsorption in the kidney's ascending loop of Henle, leading to increased excretion of water and electrolytes. It is primarily used for edema associated with heart failure, liver cirrhosis, and renal disease.

Memory Aids
Mnemonic
ETHyl + ACRYlic + NICotinic → Think of it as a synthetic compound built from parts of these chemical names, which is an ACID that makes you excrete (E-th-acry-nic).
Conceptual Metaphor
N/A. The term is a technical label, not conceptual.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'этакриновая кислота' without verifying the official pharmacopoeia term (which is 'этакриновая кислота'). The stress pattern differs from English.
- Do not confuse with 'acetylsalicylic acid' (aspirin) due to the '-ic acid' ending.
Common Mistakes
- Mispronunciation: /ˈɛθəkraɪnɪk/ (incorrect stress).
- Misspelling: 'ethacrinic', 'ethacrynicacid' (as one word).
- Confusing it with other diuretics like furosemide, though they are in the same class.

FAQ
Frequently Asked Questions
No, it is a second-line or special-use diuretic, typically reserved for cases where more common loop diuretics like furosemide are ineffective or contraindicated due to allergy.
Absolutely not. It is a potent prescription-only medication due to its significant side effects, including severe electrolyte disturbances and potential for ototoxicity (hearing damage).
The main risks are profound dehydration, electrolyte imbalances (low potassium, sodium), and hearing loss, especially with rapid intravenous administration or high doses.
While both are loop diuretics, ethacrynic acid is not a sulfonamide derivative, making it usable in patients with sulfa allergies. It is also considered to have a slightly higher risk of ototoxicity.
