Guanethidine, an antihypertensive medication, reduces the release of catecholamines such as norepinephrine. Guanethidine crosses the sympathetic nerve membrane using the same mechanism as norepinephrine (NET, uptake 1, and this are critical for its action). Once guanethidine enters the nerve, it is concentrated within transmitter vesicles where it replaces norepinephrine. Guanethidine may also decrease the amount of norepinephrine released, which can inhibit the release and accumulation of granules. Guanethidine used to be a standard for hypertension-resistant agents. It was used safely during pregnancy but is not available in the United States. For the quick control of hypertensive emergencies, it is still available in certain countries (e.g. UK). Guanethidine can be used intravenously to block nerves (Bier block), which is used to treat chronic pain due to complex regional pain syndrome. Side effects include exercise and postural hypotension, delayed or retrograde ejaculation, and diarrhea. Guanethidine can be transported via uptake 1 to the presynaptic terminus by norepinephrine transporter (NET). This allows it to potentiate exogenously administered norepinephrine by competing with it. It is found in norepinephrine transmitters' vesicles and replaces norepinephrine. This causes a gradual loss of norepinephrine in nerve endings. It blocks norepinephrine's release when it reaches the terminal. It does not affect spontaneous release.
Guanethidine is a neuroeffector that inhibits or interferes with the release and/or dissemination of norepinephrine. It does not act at the effector cells by inhibiting the association between norepinephrine and its receptors. Guanethidine is taken up by norepinephrine transportation and concentrated in transmitter vesicles instead of NE. This causes gradual depletion in nerve endings' NE stores. Guanethidine blocks noradrenaline's release at the nerve terminal in response to an attack potential. Guanethidine, unlike ganglionic blocking drugs, suppresses the same responses mediated via alpha- and beta-adrenergic receptors. However, it does not cause parasympathetic blockade. Guanethidine reduces blood pressure in the supine posture due to sympathetic blockade. This results in a modest decrease in cardiac output and peripheral resistance. Guanethidine further lowers blood pressure by decreasing vasoconstriction, which is normal due to reflex sympathetic nerve activity when the upright position is assumed. This reduces venous return as well as cardiac output. The main driver of the guanethidine industry is an increase in stroke and hypertension cases. Hypertension has been exacerbated by the increased consumption of unhealthy and unbalanced food, irregular work hours, and poor sleep. Globally, hypertension and stroke cases are also increasing due to an increase in the elderly population. The availability of substitutes can limit the market. There are many antihypertensive medications on the market, and the most popular are thiazide diuretics. This inhibits the growth of the guanethidine industry. Investors are attracted to market growth by the current pandemic.
