Among its pronounced side effects, orthostatic hypotension has been reported in approximately 15% of patients taking guanethidine. This powerful adrenergic neuron blocker is known for its challenging adverse effect profile, which includes several major systemic issues beyond its hypotensive action.

Over 50 years ago, guanethidine was an important medication for treating severe hypertension, with its primary brand name being Ismelin. Although effective, it has since been discontinued for oral use in many regions, including the United States, due to the availability of newer, safer, and more tolerable alternatives. Understanding the history of this drug, its brand name, and why it was phased out is key to appreciating the evolution of modern pharmacology.

The antihypertensive medication Guanethidine has been discontinued and is no longer available in the United States for oral use. The drug, once a frontline treatment for severe hypertension, was replaced due to significant side effects and the development of superior medications.

Though Azocane itself has limited direct medical uses, it serves as a critical pharmaceutical intermediate in the synthesis of important drugs, such as the antihypertensive agent guanethidine. Its significance lies not in its direct application but in the wide range of biologically active derivatives that can be synthesized from its eight-membered ring structure.
