Amantadine (Symmetrel) is a drug that has US Food and Drug Administration approval for use both as an antiviral and an antiparkinsonian drug.Amantadine is a weak antagonist of the NMDA type glutamate receptor, increases dopamine release, and blocks dopamine reuptake.Amantadine has been associated with several central nervous system (CNS) side effects, likely due to amantadine's dopaminergic and adrenergic activity, and to a lesser extent, its activity as an anticholinergic.
NMDA receptor antagonists are a class of anesthetics that work to antagonize, or inhibit the action of, the N-methyl d-aspartate receptor (NMDAR). They are used as anesthesia for animals and, less commonly, for humans; the state of anesthesia they induce is referred to as dissociative anesthesia. Memantine is an uncompetitive NMDA channel blocker. Memantine is the first in a novel class of Alzheimer's disease medications acting on the glutamatergic system by blocking NMDA glutamate receptors.
Bupropion (Wellbutrin, Zyban) is an atypical antidepressant and smoking cessation aid. Its chemical name is β-keto-3-chloro-N-tert-butylamphetamine, a substituted cathinone (β-ketoamphetamine), as well as substituted amphetamine. Its primary action is thought to be NE-DA reuptake inhibition. It binds selectively to the dopamine transporter, but its behavioural effects have often been attributed to its inhibition of NE reuptake. It also acts as a nicotinic ACh receptor antagonist.
Dihydrotachysterol (DHT) is a synthetic vitamin D analog activated in the liver that does not require renal hydroxylation like vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). DHT has a rapid onset of action (2 hours), a shorter half-life, and a greater effect on mineralization of bone salts than does vitamin D
Bupropion (Wellbutrin, Zyban, Voxra, Budeprion, Prexaton, Elontril or Aplenzin ) is an atypical antidepressant and smoking cessation aid. It is a norepinephrine-dopamine reuptake inhibitor. It is also a nicotinic acetylcholine receptor antagonist. Treatment of Hypoactive Sexual Desire Disorder (HSDD) in women.
E or NE bind either α1, α2 or β-adrenergic receptors. α1 couples to Gq, which results in increased intracellular Ca2+ which results in smooth muscle contraction. α2, on the other hand, couples to Gi, which causes a decrease of cAMP activity, resulting in smooth muscle contraction. β receptors couple to Gs, and increases intracellular cAMP activity, resulting in e.g. heart muscle contraction, smooth muscle relaxation and glycogenolysis.
Diazepam (Valium) is a benzodiazepine drug.Diazepam binds to a specific subunit on the GABAA receptor at a site distinct from the binding site of the endogenous GABA molecule, known as an allosteric site. Diazepam is also a PDE4 inhibitor: en.wikipedia.org/...
