Definition
Noun 1. A pharmaceutical drug: Mexitil is the trade name for the generic antiarrhythmic medication mexiletine hydrochloride. It is primarily used in the treatment of certain serious, irregular heart rhythms originating in the ventricles (the lower chambers of the heart).
Examples of Usage
- Noun:
- The cardiologist prescribed Mexitil to manage the patient's ventricular tachycardia.
- Mexitil works by stabilizing the heart's electrical activity to prevent dangerous arrhythmias.

Advanced Usage
- Medical Context: The term is used almost exclusively in clinical, pharmacological, and patient-care settings. It is a proper noun (a brand/trade name) and is often capitalized.
- Mechanism of Action: In advanced medical discussion, Mexitil is classified as a Class IB antiarrhythmic agent. It works by blocking sodium channels in heart cells, which slows electrical conduction in the ventricles and helps to regularize the heartbeat.
