Question

The primary mechanism of action of this group of medications is

as 5-HT2 D1 D2, and D4 receptor antagonists: a. Sertraline b. All
answers are correct c. Duloxetine d.’ Risperidone e. Biperide

Answer 1

Risperidone is the correct answer, as it acts as an antagonist for 5-HT2, D1, D2, and D4 receptors. It is an antipsychotic drug, unlike SSRIs like Sertraline and Duloxetine that increase serotonin levels by inhibiting reuptake.

Step-by-step explanation:

The medication described as a 5-HT2, D1, D2, and D4 receptor antagonist is Risperidone. This class of drugs are antipsychotics used to treat various psychiatric conditions by affecting neurotransmitter receptors in the brain. Risperidone is specifically known for its use in treating schizophrenia, bipolar disorder, and irritability associated with autism. It is fundamentally different from drugs like Sertraline and Duloxetine, which are Selective Serotonin Reuptake Inhibitors (SSRIs). SSRIs, such as Prozac, Paxil, and Zoloft, increase serotonin levels in the brain by preventing the reuptake of serotonin into the presynaptic neuron, which is beneficial in treating depression.
