Neurologic complications of ketoconazole therapy for advanced prostatic cancer
1King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia.
Abstract:
Ketoconazole, an antifungal agent, has been recently used for the treatment of metastatic (Stage D) prostatic carcinoma. It acts by blocking the synthesis of androgens in the tests and adrenal glands. Its major side effects are gastrointestinal and hepatic. We describe a patient in whom severe mental disturbances developed following ketoconazole treatment. Symptoms improved after withdrawal of the drug.
Insights
Ketoconazole, an antifungal, can treat advanced prostate cancer by blocking androgen synthesis. However, this drug may cause severe mental disturbances, as seen in one patient whose symptoms resolved after discontinuation.
Area of Science:
- Pharmacology
- Oncology
- Endocrinology
Background:
- Ketoconazole is an antifungal medication repurposed for metastatic (Stage D) prostate carcinoma treatment.
- It functions by inhibiting androgen synthesis in the testes and adrenal glands, crucial for prostate cancer progression.
Observation:
- A patient undergoing ketoconazole therapy for advanced prostate cancer developed severe mental disturbances.
- These adverse psychological effects emerged during the course of treatment.
Findings:
- The patient's severe mental disturbances were directly linked to ketoconazole administration.
- Discontinuation of ketoconazole led to a significant improvement in the patient's mental state.
Implications:
- This case highlights potential neuropsychiatric side effects of ketoconazole, beyond its known gastrointestinal and hepatic toxicities.
- Clinicians should monitor for mental health changes in patients treated with ketoconazole for prostate cancer.
- Further research is warranted to understand the mechanism and prevalence of ketoconazole-induced mental disturbances.
