Insights
Carvedilol, a heart failure drug, may also treat benign prostatic hypertrophy symptoms. Replacing it with bisoprolol caused urinary retention, which resolved upon returning to carvedilol.
Area of Science:
- Cardiology
- Urology
- Pharmacology
Background:
- Heart failure (HF) and benign prostatic hypertrophy (BPH) frequently coexist in older men.
- Carvedilol uniquely combines beta-blockade for HF with alpha-1 blockade, a mechanism used for BPH treatment.
Observation:
- A patient with HF and BPH experienced acute urinary retention after switching from carvedilol to bisoprolol.
- Reinstatement of carvedilol led to the resolution of BPH symptoms.
Findings:
- The patient's BPH was later confirmed by digital rectal exam.
- Six months post-carvedilol reinstitution, BPH symptoms remained resolved.
Implications:
- Carvedilol may be a viable option for managing HF with systolic dysfunction in men with concurrent BPH.
- This could potentially eliminate the need for separate alpha-1 adrenergic blockers for BPH treatment.
Abstract:
Heart failure (HF) and benign prostatic hypertrophy (BPH) are two conditions that commonly coexist in men 60 years and older. Carvedilol is the only β-adrenergic blocker approved for HF that also has additional α1-adrenergic blockade. As α1-adrenergic blockers are used in the treatment of BPH, it is intuitive that carvediolol could improve BPH symptoms. We present a case where carvedilol was replaced with bisoprolol resulting in acute urinary retention. When carvediolol was reinstituted, the patient's symptoms of BPH resolved. Benign prostatic hypertrophy was later diagnosed by digital rectal exam. Six month after reinstituting the carvediolol, the patient remains free of his BPH symptoms. This case suggests that carvedilol may be considered for the management of HF with systolic dysfunction in patients with concomitant BPH thus eliminating the need for an α1-adrenergic blockers.
