What is Hexamethonium?
Hexamethonium is a medication that belongs to a class of drugs known as ganglionic blockers. It acts by blocking the transmission of nerve impulses between ganglia in the autonomic nervous system. This medication was historically used to treat hypertension (high blood pressure) but has largely been replaced by newer medications with fewer side effects.
How Does Hexamethonium Work?
Hexamethonium works by binding to and inhibiting the nicotinic receptors located on the postganglionic neurons within autonomic ganglia. This action prevents the normal function of these receptors, ultimately leading to a decrease in sympathetic nervous system activity. By reducing the signaling between nerves, hexamethonium helps lower blood pressure by reducing the responsiveness of blood vessels to nerve stimuli.
Side Effects of Hexamethonium
Common side effects of hexamethonium include dry mouth, constipation, blurred vision, and urinary retention. Because of its mechanism of action as a ganglionic blocker, hexamethonium can cause significant blood pressure reductions, leading to dizziness and potential fainting. Due to these side effects, the use of hexamethonium has declined over the years in favor of newer and safer antihypertensive medications.
Contraindications and Precautions
Hypotension and hypersensitivity to hexamethonium are common contraindications to its use. Patients with a history of syncope or severe orthostatic hypotension should also avoid hexamethonium. Additionally, caution should be exercised when using this medication in elderly patients, as they may be more sensitive to its blood pressure-lowering effects.
Conclusion
While hexamethonium was once a commonly used medication for hypertension, its use has decreased due to the availability of safer and more effective alternatives. Understanding how hexamethonium works and its potential side effects is important for healthcare providers in making informed decisions about the management of hypertension.
