Which of the following antibiotic can cause cholestatic jaundice
Common antibiotics that cause cholestasis... Hmm. I remember that erythromycin is a big one. Oh wait, maybe it's the macrolides in general? Also, there's a class effect here. Then there's the cephalosporins, but I'm not sure. Oh, and maybe some penicillins? Wait, but the question is about cholestatic jaundice specifically.
Wait, another one is amoxicillin-clavulanate. Clavulanate is known to cause cholestasis. So if the options include that, that's a possibility. Also, some sulfa drugs, maybe? But maybe the most classic is erythromycin. Let me think. Erythromycin estolate was notorious for causing cholestatic jaundice. So if the options include erythromycin estolate, that's the answer.
Now, why do these drugs cause cholestasis? It's an idiosyncratic reaction, right? They interfere with the bile canaliculi, leading to accumulation of bilirubin. The mechanism isn't fully understood, but it's a type of hepatotoxicity. So the correct answer would be an antibiotic known for this effect.
Looking at the options, if one of them is erythromycin estolate, then that's the correct choice. If another is amoxicillin-clavulanate, that's also possible. But I think erythromycin estolate is more classic. Let me confirm. Yes, erythromycin estolate is a classic example. So if the correct answer is that, then the explanation should focus on that.
The other options: if they include drugs like penicillin G, which doesn't cause cholestasis, or maybe tetracycline, which is more about hepatotoxicity in general but not cholestasis. Or maybe aminoglycosides, which are nephrotoxic. So each wrong option can be explained by their primary side effects.
Clinical pearl: Remember that cholestatic jaundice from drugs is often reversible upon discontinuation. Also, the mnemonic for hepatotoxic antibiotics includes Erythromycin estolate, isoniazid, and others. But the key here is cholestasis specifically. So the high-yield fact is to associate erythromycin estolate with cholestatic jaundice.
So putting it all together, the correct answer is the antibiotic that's known for causing cholestasis, like erythromycin estolate. The explanation should cover the mechanism, why the other options aren't correct, and the clinical tip.
**Core Concept**
Cholestatic jaundice results from impaired bile flow, often due to drug-induced injury to hepatocytes or bile ducts. Certain antibiotics, particularly macrolides like erythromycin estolate, are notorious for causing this condition via idiosyncratic hepatic toxicity.
**Why the Correct Answer is Right**
Erythromycin estolate causes cholestatic jaundice by inducing intrahepatic cholestasis through direct hepatoc
