Summary
Chlorpromazine can cause blue-gray skin discoloration due to pigment deposits in the dermis. This study investigated the complex mechanism behind this drug-induced hyperpigmentation.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Chlorpromazine is known to cause skin hyperpigmentation, particularly in sun-exposed areas.
- This discoloration can range from slate-gray to blue-gray.
- The exact mechanism of chlorpromazine-induced hyperpigmentation is not fully understood.
