What is the primary use of LTRAs?

  1. Treatment of acute asthma attacks

  2. Oral prophylaxis and long-term treatment of asthma

  3. Immediate relief from allergic reactions

  4. Cure for respiratory infections

The correct answer is: Oral prophylaxis and long-term treatment of asthma

LTRAs or Leukotriene Receptor Antagonists are primarily used for oral prophylaxis and long-term treatment of asthma. They work by blocking the action of leukotrienes, which are inflammatory chemicals produced by the body in response to asthma triggers. This helps to reduce inflammation and mucus production in the airways, making breathing easier for people with asthma. Option A is incorrect because LTRAs are not used for treating acute asthma attacks. In these situations, fast-acting rescue inhalers are more effective. Option C is incorrect because LTRAs do not provide immediate relief from allergic reactions such as hives or anaphylaxis. They are specifically targeted for reducing inflammation in the airways. Option D is incorrect because LTRAs cannot cure respiratory infections. They can only help with managing asthma symptoms in the long-term.
