Drugs acting on Digestive System..Lab-1

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.
These are the drugs which stop vomiting.
Examples… Gravinate, Motilium and Epicac.
These are the drugs which induce vomiting.
Examples… These include common salts e.g. sodium chloride, copper sulphate, zinc sulphate, magnesium sulphate. All these salts must be diluted.
Vomiting center is in a region called chemoreceptor trigger zone which is present on the floor of the fourth ventricle of the brain.
These are the drugs which increase intestinal motility and rate of passage of contents from the intestine. These drugs relieve from constipation.
Examples… Liquid Paraffin, Conspic drops, Ispaghol, sikklix and lexabone.
These are the drugs which increase intestinal motility and cause rapid expulsion of contents from the intestine(shooting diarrhea).
Examples… Magnesium sulphate, castor oil, Agar and Bran.
These drugs cause removal of gases from the stomach and improve digestion. These are used in conditions like tympany/bloat.
Examples… Carminative mixture, Clove, Aniseed, Peppermint oil and Ginger.
These are the drugs which increase intestinal motility and act as tonic. These drugs increase apetite.
Examples… Gention, Cherrita, Black Salt, Mocigar(syp), Lederplex(syp) and Hepamerg(liver tonic).
