Quizplus · Accepted Answer

Lactulose is a medication that helps to lower serum NH3 levels by reducing the amount of ammonia absorbed by the intestines and increasing its excretion through feces. Neomycin and anti-NH3 metabolites also have some potential to lower serum NH3 levels, but lactulose is the preferred medication for this purpose. Vitamin K is not used to lower serum NH3 levels. Lactulose is commonly used to assist in lowering serum NH3 levels in patients with hepatic encephalopathy. It works by promoting the excretion of NH3 in the stool. Neomycin may also be used, but its use is typically limited due to potential side effects and development of antibiotic resistance. There is no medication referred to as an "anti-NH3 metabolite." Vitamin K is not used to lower serum NH3 levels.
