Guanochlor
Guanochlor (pronounced: gwa-no-klor) is a sympatholytic drug that acts as an adrenergic antagonist. It is primarily used in the treatment of hypertension (high blood pressure).
Etymology
The term "Guanochlor" is derived from the chemical structure of the drug, which contains a guanidine group and a chlorine atom. The prefix "guano-" refers to the guanidine group, and "-chlor" refers to the chlorine atom.
Pharmacology
Guanochlor works by blocking the action of norepinephrine and epinephrine (also known as adrenaline) on the adrenergic receptors. This reduces the overall activity of the sympathetic nervous system, which in turn lowers blood pressure.
