pentoxyfylline – xanthine derivative used in as an antiinflammatory drug and in the prevention of endotoxemia; pergolide – dopamine receptor agonist used for the treatment of pituitary pars intermedia dysfunction in horses; phenobarbital – anti-convulsant used for seizures; phenylbutazone – nonsteroidal anti-inflammatory drug (NSAID)
The test can detect antipsychotic-like activity both in the case of dopamine D 2 receptor antagonists and in the case of drugs lacking D 2 receptor antagonism. [1] [2] [6] The occupancy of the D 2 receptor by antagonists of this receptor required to inhibit the CAR is around 65 to 80%, which is similar to the occupancy at which therapeutic antipsychotic effects occur in humans with these drugs.
Maropitant (INN; [3] brand name: Cerenia, used as maropitant citrate , is a neurokinin-1 (NK 1) receptor antagonist developed by Zoetis specifically for the treatment of motion sickness and vomiting in dogs. It was approved by the FDA in 2007, for use in dogs [4] [5] and in 2012, for cats. [6]
Apomorphine, sold under the brand name Apokyn among others, is a type of aporphine having activity as a non-selective dopamine agonist which activates both D 2-like and, to a much lesser extent, D 1-like receptors. [2] It also acts as an antagonist of 5-HT 2 and α-adrenergic receptors with high affinity.
Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS) and are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling.
It is unclear if dopamine is safe to use during pregnancy or breastfeeding. [4] At low doses dopamine mainly triggers dopamine receptors and β1-adrenergic receptors while at high doses it works via α-adrenergic receptors. [4] Dopamine was first synthesized in a laboratory in 1910 by George Barger and James Ewens in England. [8]
While acepromazine is also used in cats, its absorption is erratic and can vary between individuals. It also generally induces less sedation than in dogs. [13] [14] It also causes spontaneous motor activity (in both cats and dogs, but more often in cats) by blocking dopamine receptors in the striatum and substantia nigra. [15]
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.
