Answer #1

Leukotriene receptor antagonist (LTRA) drugs are used to prevent the inflammation of the airway and improve the air circulation. It is usually recommended in asthma where instead of increasing the steroid dose this medication is a preffered choice.It can be categorized as bronchodialtor.It release the chemical necessary to stop this reaction. Leukoterine release or increased amount can lead to bronchoconstriction,inflammation. During any allergy or in condition like asthma the histamines are released and construct the bronchial tubes and causing breathing difficult.This drug prevents the formation of histaminw or its release during a trigger and thus preventing symptoms

Ans:b)inhibit histamine release

    The antihistamine diphenhydramine is a histamine receptor antagonist used to inhibit histamine release in allergic conditions. However, it also acts on the same receptors in the central nervous system, leading to somnolence (sleepiness or drowsiness). This adverse effect led to the design of second-generation antihistamines that do not cross the blood-brain barrier and thus do not induce drowsiness. The first of these new antagonists was the drug terfenadine. This drug inhibits histamine receptors in the G tract, large blood vessels,...
