Drugs acting on Digestive System:
Drugs acting on the digestive system are classified in different groups based on the mode of action.
Drugs used for the treatment of the diarrhea are called antidiarrhoeals. Diarrhea is the condition in which intestinal motility increases and result in the water loss from the body.
Examples... Sulphadimidine, Metronidazole, Flagyl and Entox. Flagyl is both antidiarrhoeal and antiemetic(which stops vomiting) as well. In addition, Diaroban powder for compound stomach animals and Streptomegma for mono stomach animals are also used.
Antacids are the drugs which reduce acidity in the stomach. Acidity is increased due to more protein intake and in result increase in HCL production.
Examples… Sodium Bicarbonate, Gatrophyll, Mucaine and Omeprazole.
