Nomifensine (Merital, Alival) is a norepinephrine-dopamine reuptake inhibitor, i.e. a drug that increases the amount of synaptic norepinephrine and dopamine available to receptors by blocking the dopamine and norepinephrine reuptake transporters. [2] This is a mechanism of action shared by some recreational drugs like cocaine and the medication tametraline (see DRI). Research showed that the (S)-isomer is responsible for activity. [3]

Contents

The drug was developed in the 1960s by Hoechst AG (now Sanofi-Aventis), [4] who then test marketed it in the United States. It was an effective antidepressant, without sedative effects. Nomifensine did not interact significantly with alcohol and lacked anticholinergic effects. No withdrawal symptoms were seen after 6 months treatment. The drug was however considered not suitable for agitated patients as it presumably made agitation worse. [5] [6] In January 1986 the drug was withdrawn by its manufacturers for safety reasons. [7]

Some case reports in the 1980s suggested that there was potential for psychological dependence on nomifensine, typically in patients with a history of stimulant addiction, or when the drug was used in very high doses (400–600 mg per day). [8]

In a 1989 study it was investigated for use in treating adult ADHD and proven effective. [9] In a 1977 study it has not proven of benefit in advanced parkinsonism, except for depression associated with the parkinsonism. [10]

Clinical uses

Nomifensine was investigated for use as an antidepressant in the 1970s, and was found to be a useful antidepressant at doses of 50–225 mg per day, both motivating and anxiolytic.

Side effects and withdrawal from market

During treatment with nomifensine there were relatively few adverse effects, mainly renal failure, paranoid symptoms, drowsiness or insomnia, headache, and dry mouth. Side effects affecting the cardiovascular system included tachycardia and palpitations, but nomifensine was significantly less cardiotoxic than the standard tricyclic antidepressants. [11]

Due to a risk of haemolytic anaemia, the U.S. Food and Drug Administration (FDA) withdrew approval for nomifensine on March 20, 1992. Nomifensine was subsequently withdrawn from the Canadian and UK markets as well. [12] Some deaths were linked to immunohaemolytic anemia caused by this compound, although the mechanism remained unclear. [13]

In 2012 structure-affinity relationship data (compare SAR) were published. [14]

Synthesis

Note that nomifensine was a Progenitor to Gastrophenazine. [15] See also: Isatin derivatives. [16]

The alkylation between N-methyl-2-nitrobenzylamine [56222-08-3] (1) and phenacyl bromide (2) gives CID:15326127 (3). Catalytic hydrogenation over Raney Nickel reduces the nitro group to give CID:15113381 (4). The reduction of the ketone group with sodium borohydride to alcohol gives [65514-97-8] (5). Acid catalysed ring closure completes the formation of nomifensine (6).

<span class="mw-page-title-main">Serotonin–norepinephrine reuptake inhibitor</span> Class of antidepressant medication

Serotonin–norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant medications used to treat major depressive disorder (MDD), anxiety disorders, obsessive–compulsive disorder (OCD), social phobia, attention-deficit hyperactivity disorder (ADHD), chronic neuropathic pain, fibromyalgia syndrome (FMS), and menopausal symptoms. SNRIs are monoamine reuptake inhibitors; specifically, they inhibit the reuptake of serotonin and norepinephrine. These neurotransmitters are thought to play an important role in mood regulation. SNRIs can be contrasted with the more widely used selective serotonin reuptake inhibitors (SSRIs), which act upon serotonin only.

A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron. This results in increased extracellular concentrations of dopamine and increase in dopaminergic neurotransmission.

<span class="mw-page-title-main">Trimipramine</span> Antidepressant

Trimipramine, sold under the brand name Surmontil among others, is a tricyclic antidepressant (TCA) which is used to treat depression. It has also been used for its sedative, anxiolytic, and weak antipsychotic effects in the treatment of insomnia, anxiety disorders, and psychosis, respectively. The drug is described as an atypical or "second-generation" TCA because, unlike other TCAs, it seems to be a fairly weak monoamine reuptake inhibitor. Similarly to other TCAs however, trimipramine does have antihistamine, antiserotonergic, antiadrenergic, antidopaminergic, and anticholinergic activities.

<span class="mw-page-title-main">Milnacipran</span> Antidepressant

Milnacipran is a serotonin–norepinephrine reuptake inhibitor (SNRI) used in the clinical treatment of fibromyalgia. It is not approved for the clinical treatment of major depressive disorder in the US, but it is in other countries.

A serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI), also known as a triple reuptake inhibitor (TRI), is a type of drug that acts as a combined reuptake inhibitor of the monoamine neurotransmitters serotonin, norepinephrine, and dopamine. It does this by concomitantly inhibiting the serotonin transporter (SERT), norepinephrine transporter (NET), and dopamine transporter (DAT), respectively. Inhibition of the reuptake of these neurotransmitters increases their extracellular concentrations and, therefore, results in an increase in serotonergic, adrenergic, and dopaminergic neurotransmission.

Nisoxetine, originally synthesized in the Lilly research laboratories during the early 1970s, is a potent and selective inhibitor for the reuptake of norepinephrine (noradrenaline) into synapses. It currently has no clinical applications in humans, although it was originally researched as an antidepressant. Nisoxetine is now widely used in scientific research as a standard selective norepinephrine reuptake inhibitor. It has been used to research obesity and energy balance, and exerts some local analgesia effects.

LR-5182 is a stimulant drug which acts as a norepinephrine–dopamine reuptake inhibitor, structurally related to the better known drug fencamfamine. It was developed by the pharmaceutical company Eli Lilly in the 1970s, and researched for potential use as an antidepressant, although never marketed. LR-5182 has two stereoisomers, both of which are active, although one isomer blocks reuptake of only dopamine and noradrenaline, while the other blocks reuptake of serotonin as well.

Diclofensine was developed by Hoffmann-La Roche in the 1970s in the search for a new antidepressant. It was found that the (S)-isomer was responsible for activity. Is a stimulant drug which acts as a triple monoamine reuptake inhibitor, primarily inhibiting the reuptake of dopamine and norepinephrine, with affinities (Ki) of 16.8 nM, 15.7 nM, and 51 nM for DAT, NET, and SERT, respectively. It was found to be an effective antidepressant in human trials, with relatively few side effects, but was ultimately dropped from clinical development, possibly due to concerns about its abuse potential.

Ciclazindol (WY-23409) is an antidepressant and anorectic drug of the tetracyclic chemical class that was developed in the mid to late 1970s, but was never marketed. It acts as a norepinephrine reuptake inhibitor, and to a lesser extent as a dopamine reuptake inhibitor. Ciclazindol has no effects on the SERT, 5-HT receptors, mACh receptors, or α-adrenergic receptors, and has only weak affinity for the H1 receptor. As suggested by its local anesthetic properties, ciclazindol may also inhibit sodium channels. It is known to block potassium channels as well.

Tandamine is a selective norepinephrine reuptake inhibitor with a tricyclic structure. It was developed in the 1970s as an antidepressant but was never commercialized. Tandamine is analogous to pirandamine, which, instead, acts as a selective serotonin reuptake inhibitor (SSRI).

<span class="mw-page-title-main">Eugeroic</span> Drugs for wakefulness and alertness

Eugeroics, also known as wakefulness-promoting agents and wakefulness-promoting drugs, are a class of drugs that promote wakefulness and alertness. They are medically indicated for the treatment of certain sleep disorders including excessive daytime sleepiness (EDS) in narcolepsy or obstructive sleep apnea (OSA). Eugeroics are also often prescribed off-label for the treatment of EDS in idiopathic hypersomnia. In contrast to classical psychostimulants, such as methylphenidate and amphetamine, which are also used in the treatment of these disorders, eugeroics typically do not produce euphoria, and, consequently, have a lower addictive potential.

<span class="mw-page-title-main">Serotonin–dopamine reuptake inhibitor</span>

A serotonin–dopamine reuptake inhibitor (SDRI) is a type of drug which acts as a reuptake inhibitor of the monoamine neurotransmitters serotonin and dopamine by blocking the actions of the serotonin transporter (SERT) and dopamine transporter (DAT), respectively. This in turn leads to increased extracellular concentrations of serotonin and dopamine, and, therefore, an increase in serotonergic and dopaminergic neurotransmission.

A monoamine reuptake inhibitor (MRI) is a drug that acts as a reuptake inhibitor of one or more of the three major monoamine neurotransmitters serotonin, norepinephrine, and dopamine by blocking the action of one or more of the respective monoamine transporters (MATs), which include the serotonin transporter (SERT), norepinephrine transporter (NET), and dopamine transporter (DAT). This in turn results in an increase in the synaptic concentrations of one or more of these neurotransmitters and therefore an increase in monoaminergic neurotransmission.

Selective norepinephrine reuptake inhibitors (sNRIs) are a class of drugs that have been marketed as antidepressants and are used for various mental disorders, mainly depression and attention-deficit hyperactivity disorder (ADHD). The norepinephrine transporter (NET) serves as the fundamental mechanism for the inactivation of noradrenergic signaling because of the NET termination in the reuptake of norepinephrine (NE). The selectivity and mechanism of action for the NRI drugs remain mostly unresolved and, to date, only a limited number of NRI-selective inhibitors are available. The first commercially available selective NRI was the drug reboxetine (Edronax), developed as a first-line therapy for major depressive disorder. Atomoxetine (Strattera) is another potent and selective NRI which is also effective and well tolerated for the treatment of ADHD in adults; it may also be a new treatment option for adults with ADHD, particularly for those patients at risk of substance abuse.
