Question

Amongst the following antihistamines, which are antacids?
A.Ranitidine
B.Brompheniramine
C.Terfenadine
D.Cimetidine

Answer 1

Hint:Antacids are the substances which neutralizes the acid of the stomach. Its constituent ingredients are basic or alkaline in nature which are magnesium, calcium or the aluminium or sodium bicarbonate which increases the pH value of the stomach.

Complete step by step answer:Histamine: Histamine is a nitrogen containing organic compound which involves regulating physiological function in the gut, in local immune responses and acting as a neurotransmitter for various organs such as uterus, spinal cord and brain. It acts as a vasodilator for blood vessels increasing the flow of blood through the vessels and is involved in inflammatory responses at the site of injury.
Ranitidine: It belongs to the drug which blocks the function of histamine. It is commonly used in treatment of gastroesophageal disease, peptic ulcer disease, and Zollinger–Ellison syndrome. It has the property of reducing the acidity of the stomach.
Brompheniramine: The role of this drug is to treat the symptoms caused by flu, cold, breathing illness and allergies. Its antihistamine property helps in reducing the allergic reaction symptoms which include itchy eyes, nose, watery eyes and sneezing.
Terfenadine: It is the drug which was used to treat the allergic reactions but due to its adverse and lethal effect on heart rhythms it was banned.
Cimetidine: It is a drug which is similar to ranitidine but its potential is more as compared to ranitidine. It also belongs to the category of histamine blockers and is preferred more because of its potency in comparison to ranitidine. It also cures the acidity of the stomach.
Thus here we have two correct options A and D, since they both are antihistamines and are used as antacids to reduce the acidity.


Note: The urban lifestyle is day by day increasing and there are situations where the acidity is quite normal, so the drugs should be able to neutralize the produced drug and should not produce any lethal effect at another site.
