Conditions:
Guanadrel is a postganglionic adrenergic blocking agent. Uptake of guanadrel and storage in sympathetic neurons occurs via the norepinephrine pump or transporter. Guanadrel slowly displaces norepinephrine from its storage in nerve endings and thereby blocks the release of norepinephrine normally produced by nerve stimulation. The reduction in neurotransmitter release in response to sympathetic nerve stimulation, as a result of catecholamine depletion, leads to reduced arteriolar vasoconstriction, especially the reflex increase in sympathetic tone that occurs with a change in position. Guanadrel is used to treat and control hypertension.

Class (Stereo):
CHEMICAL (ACHIRAL)
Targets:
Maprotiline is a tetracyclic antidepressant with similar pharmacological properties to tricyclic antidepressants (TCAs). Similar to TCAs, maprotiline inhibits neuronal norepinephrine reuptake, possesses some anticholinergic activity, and does not affect monoamine oxidase activity. It differs from TCAs in that it does not appear to block serotonin reuptake. Maprotiline may be used to treat depressive affective disorders, including dysthymic disorder (depressive neurosis) and major depressive disorder. Maprotiline is effective at reducing symptoms of anxiety associated with depression. The mechanism of action of maprotiline is not precisely known. It does not act primarily by stimulation of the central nervous system and is not a monoamine oxidase inhibitor. The postulated mechanism of maprotiline is that it acts primarily by potentiation of central adrenergic synapses by blocking reuptake of norepinephrine at nerve endings. This pharmacologic action is thought to be responsible for the drug’s antidepressant and anxiolytic effects. The mean time to peak is 12 hours. The half-life of elimination averages 51 hours.

CHEMICAL (ACHIRAL)
Bretylium (bretylium tosylate) is an antifibrillatory and antiarrhythmic agent. Bretylium is abromobenzyl quaternary ammonium compound which selectively accumulates in sympathetic ganglia and their postganglionic adrenergic neurons where it inhibits norepinephrine release by depressing adrenergic nerve terminal excitability. The drug has a direct positive inotropic effect on the myocardium and blocking effect on postganglionic sympathetic nerve transmission. The drug is poorly absorbed orally, requiring either i.m. or i.v. administration.

CHEMICAL (ACHIRAL)
Targets:
Conditions:
Guanethidine belongs to the general class of medicines called antihypertensives. It was used to treat high blood pressure (hypertension). It is believed to act mainly by preventing the release of norepinephrine at nerve endings and causes depletion of norepinephrine in peripheral sympathetic nerve terminals as well as in tissues. It is taken up by norepinephrine transporters. It becomes concentrated in NE transmitter vesicles, replacing NE in these vesicles.

Adrenalone is a keton form of the natural substrate epinephrine. Adrenalone is evidently formed in vivo by hydrolytic cleavage of the diester by esterases. It is an adrenergic receptor agonist. Adrenalone inhibits the norepinephrine synthesis and dopamine beta oxidase. It is known to have very weak sympathomimetic activity when compared to adrenaline. Adrenalone has the high radioprotective effect. It is a topical nasal decongestant. Adrenalone has hemostatic, sympathomimetic and vasoconstrictor therapeutic functions.

Gepefrine (Pressionorm and Wintonin) is an antihypotensive agent. It was used for therapy of orthostatic dysregulation. One hour after oral administration of 30 mg or 45 mg gepefrine the blood pressure increased significantly at rest and more markedly on standing and during the step test. Gepefrine led to a reduction in pathological orthostatic regulation during the early phase as well as to the prevention of subjective and objective signs of orthostatic adjustment disorder during the late phase. Patients with insufficient rise in blood pressure during the step test (80 watts) showed after gepefrine a distinct tendency towards normalisation and the regression of subjective states of exhaustion. Gepefrine caused on average no substantive alternations in heart rate during all phases of the investigation. Complications or side-effects due to the method or the medicament were not observed.

Mianserin is a tetracyclic antidepressant used for the treatment of depression. It was investigated as an adjuvant for reduction of negative and cognitive symptoms of schizophrenia, as an aid for opioid detoxification therapy (where it reduced symptoms but lead to higher drop-out rate), and for the treatment of post-traumatic stress disorder (where it was ineffective). Mianserin has a broad spectrum of activity with the most potent binding to 5-HT2A, 5-HT2C, H1, alpha2A and alpha2C receptor.
