Aripiprazole(abilify) have an antipyschotic effect? Wtf?
Most antipyschotics antagonize D2 receptors, but ariprazole is a D2 partial agonist. What's a partial agonist? I would expect an agonist to have the opposite effect of an antagonist of the same receptor. It also fucks near histamine, serotonin, and adrenergic receptors, but I don't find this particularly interesting or atypical.
Answers:
A partial agonist can be thought of as "sort of" antagonizing the receptor. It binds the receptor, and has some dopaminergic activity, but much smaller quantity than the endogenous hormone, in this case dopamine. So it's sitting there at the receptor and preventing dopamine from exerting its full effect. Source(s): Pharmacy student
Agonist: A drug that binds to a receptor of a cell and triggers a response by the cell. An agonist regularly mimics the action of a naturally occurring substance.
An agonist produces an action. It is the converse of an antagonist which acts against and blocks an action.
Agonists and antagonists are key agents surrounded by the chemistry of the human body and important players today in pharmacology.
For example, in treating Parkinson disease, the long-used drug levodopa can end in uncontrollable, jerky body movements called dyskinesias that can inhibit a person's means to function. Dopamine agonists mimic the effects of dopamine in the brain by stimulating dopamine receptors with a lower risk of the uncontrollable and irreversible dyskinesias commonly associated with levodopa therapy.
There are agonists now for frequent of the known hormones. For example, LHRH (luteinizing hormone-releasing hormone) agonists are similar to LHRH in structure and are able to mimic the effects of LHRH, a hormone that controls sex hormones surrounded by both men and women.
The word "agonist" comes from the Late Latin agnista, contender, from the Greek agnists, contestant, from agn, contest. An agonist is a chemical contestant or contender. Source(s): http://www.medterms.com/script/main/art.…
