Once the neurotransmitter is released into the synapse, it can either bind to receptors on the post-synaptic cell, the pre-synaptic cell can re-uptake it and save it for later transmission, or it can be broken down by enzymes in the synapse specific to that certain neurotransmitter. These three different actions are major areas where drug ...
These drugs inhibit the uptake of the neurotransmitter 5-HT by blocking the SERT, thus increasing its synaptic concentration, and have shown to be efficacious in the treatment of depression, however sexual dysfunction and weight gain are two very common side-effects that result in discontinuation of treatment.
Some drugs block or stimulate the release of specific neurotransmitters. Alternatively, drugs can prevent neurotransmitter storage in synaptic vesicles by causing the synaptic vesicle membranes to leak. Drugs that prevent a neurotransmitter from binding to its receptor are called receptor antagonists. For example, drugs used to treat patients ...
Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors, blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines.
Sibutramine was the first drug for the treatment of obesity to be approved in 30 years. [17] It has been associated with increased cardiovascular events and strokes and has been withdrawn from the market in several countries and regions including the United States in 2010. [18] Tramadol: Ultram: Acute and chronic pain; 1977: A dual weak opioid ...
Norepinephrine Epinephrine. A norepinephrine reuptake inhibitor (NRI, NERI) or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the action of the norepinephrine transporter (NET).
Discovery was made on the decreased levels of certain neurotransmitters, catecholamines such as norepinephrine, dopamine and serotonin, and their role in the pathogenesis of depression. [28] These past discoveries in psychopharmacology led to the development of antidepressants and a range of drugs with different functions on those ...
Adrenergic blocking agents are a class of drugs that exhibit its pharmacological action through inhibiting the action of the sympathetic nervous system [1] in the body. The sympathetic nervous system(SNS) is an autonomic nervous system that we cannot control by will.
