Which drug is approved to control vomiting and diarrhea in dogs and cats (Centrine)?

• A. Guaifenesin
• B. Aminopentamide
• C. Potassium Bromide
• D. Xylazine

Answer: (B)

Aminopentamide is an anticholinergic that blocks muscarinic acetylcholine receptors in the gastrointestinal tract. By inhibiting parasympathetic signaling, it reduces smooth muscle contractions and secretions, which helps calm GI hypermotility and cramping that drive vomiting and diarrhea. That makes it the approved option for controlling these GI symptoms in dogs and cats under the brand Centrine. Guaifenesin is an expectorant for the respiratory tract, not the GI tract. Potassium bromide is an anticonvulsant, used for seizures. Xylazine is a sedative/analgesic with decongestant effects that is not used to treat vomiting or diarrhea.
