Azocanes

Guanethidine is an antihypertensive drug that reduces the release of catecholamines, such as norepinephrine. Guanethidine is transported across the sympathetic nerve membrane by the same mechanism that transports norepinephrine itself (NET, uptake 1), and uptake is essential for the drug's action. Once guanethidine has entered the nerve, it is concentrated in transmitter vesicles, where it replaces norepinephrine. It may also inhibit the release of granules by decreasing norepinephrine.

Azocane is a heterocyclic organic compound with the molecular formula C7H15N. It consists of a saturated eight-membered ring having seven carbon atoms and one nitrogen atom attached to a single hydrogen atom. The fully unsaturated analog of azocane is azocine.

Guanazodine is an anti-hypertensive sympatholytic drug.
