An obese patient has a diagnosis of schizophrenia. Medications that block which receptors would contribute to further weight gain?
a. H1 c. Acetylcholine
b. 5 HT2 d. Gamma-aminobutyric acid (GABA)
Answer: A
H1 receptor blockade results in weight gain, which is undesirable for an obese patient. Blocking of the other receptors would have little or no effect on the patient's weight.
