Dopamine receptor antagonism The primary action of benperidol is blockade of dopamine D2 receptors in the brain. This inhibits dopaminergic neurotransmission, especially in the mesolimbic pathway. Hyperactivity of this pathway is associated with positive symptoms of psychosis such as delusions, hallucinations, and disorganized thinking. By blocking D2 receptors, benperidol interferes with this hyperactive dopaminergic signaling, … Read more about How does Benperidol work?

Extrapyramidal side effects Benperidol can cause extrapyramidal side effects due to its dopamine receptor blocking effects. These include: Orthostatic hypotension Due to its alpha-adrenergic blocking effects, benperidol may cause a drop in blood pressure upon standing from sitting or lying down. Can lead to dizziness, lightheadedness and falls. Patient should change positions slowly. Blood pressure … Read more about What are the side effects of the drug Benperidol?

For schizophrenia, the initial dose is usually 2-10 mg orally 2-3 times per day. The dose is … Read more about What is the dosing for benperidol?

Absorption of Benperidol Benperidol is well absorbed after oral administration. It undergoes extensive first-pass metabolism in the liver, resulting in low systemic bioavailability of approximately 20-30%. This means that a large portion of an oral dose is metabolized before reaching systemic circulation. Peak plasma concentrations are achieved 3-6 hours after an oral dose. Distribution of … Read more about What are the pharmacokinetics of Benperidol?

Benperidol is a typical first-generation antipsychotic. It belongs to the chemical class of butyrophenones, a group of antipsychotics with a similar chemical core of phenylbutyrophenone. Benperidol was first introduced in the late 1950s and was one of the first neuroleptics used to treat psychoses such as schizophrenia.

Benperidol is a typical first-generation neuroleptic with the chemical name 3-[2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethyl]-2-methyl-6,7,8,9-tetrahydro-4H-pyrido[1,2- a]pyrimidin-4-one. It is a piperazine phenylisoxazole derivative. Benperidol consists of a central piperazine ring attached at one side to a phenylisoxazole unit and at the other side to a tetrahydropyridopyrimidine. The phenylene ring of the phenylisoxazole is substituted with fluorine at the 6-position. This … Read more about What is the structure of Benperidol?
