Product Description
Mechanism of action
Bretylium is an adrenergic neuronal‑blocking agent that initially releases norepinephrine from presynaptic terminals, followed by long‑lasting inhibition of catecholamine release. In cardiac tissue it prolongs action potential duration by blocking potassium channels, giving it class III antiarrhythmic properties.
Benefits and advantages
Used in electrophysiology research, arrhythmia models, sympathetic‑nerve function studies, potassium‑channel analysis and investigation of neuronal‑blocking mechanisms.
Side effects and risks
Risks include profound hypotension, dizziness, arrhythmias, GI upset and sympathetic blockade. Handle with cardiovascular‑active compound precautions.
