Elimination from the body takes place by the urinary and faecal routes, but the exact proportion contributed by each route is still unknown.
Bismuth subsalicylate is used as an antacid and antidiarrheal, and to treat some other gastrointestinal symptoms, such as nausea. The means by which this occurs is still not well documented. It is thought to be some combination of the following: • Stimulation of absorption of fluids and electrolytes by the intestinal wall (antisecretory action) • As a salicylate, reducing inflammation/irritation of stomach and intestinal lining through inhibition of … WebThe comparison of the efficiency of the commercially available photocatalysts, TiO2 and ZnO, irradiated with 365 nm and 398 nm light, is presented for the removal of two antibiotics, sulfamethazine (SMT) and sulfamethoxypyridazine (SMP).
