**Core Concept**
The concomitant use of statins with certain drugs can increase the risk of **rhabdomyolysis**, a serious syndrome due to direct or indirect muscle injury. This is often due to increased **myotoxicity** when these drugs are used together.

**Why the Correct Answer is Right**
The correct answer choice would be a drug that does not significantly increase the risk of rhabdomyolysis when used with statins. This could be due to its **pharmacokinetic** profile, not affecting the **cytochrome P450** enzyme system in a way that would increase statin levels.

**Why Each Wrong Option is Incorrect**
**Option A:** Gemfibrozil, a fibric acid derivative, increases the risk of rhabdomyolysis when used with statins by potentially increasing statin levels through **enzyme inhibition**.
**Option B:** Cyclosporin, an immunosuppressant, can increase statin levels by inhibiting **CYP3A4**, an enzyme responsible for statin metabolism.
**Option C:** Erythromycin, a macrolide antibiotic, can also inhibit **CYP3A4**, leading to increased statin levels and risk of rhabdomyolysis.

**Clinical Pearl / High-Yield Fact**
It's crucial to be aware of drug interactions that can lead to rhabdomyolysis, especially in patients on statin therapy. Monitoring for signs of muscle injury and adjusting medications accordingly can prevent this serious condition.

**Correct Answer:** D. None of the above options are provided to choose the correct answer.
