Which of the following drug used for bronchial asthma can lead to hoarseness of voice
**Core Concept**
The question is testing the side effect profiles of bronchodilator medications used in the management of bronchial asthma. **Adrenergic agonists**, specifically **β2-adrenergic agonists**, are a class of medications commonly used as bronchodilators in asthma. These medications work by stimulating β2-adrenergic receptors in the lungs, leading to relaxation of bronchial smooth muscles and bronchodilation.
**Why the Correct Answer is Right**
One of the side effects of **β2-adrenergic agonists** is **hoarseness of voice**, which is caused by the stimulation of β2-adrenergic receptors in the laryngeal muscles. This leads to increased tone and stiffness of the vocal cords, resulting in a change in voice quality. **Salbutamol** (also known as albuterol) and **terbutaline** are examples of β2-adrenergic agonists that can cause hoarseness of voice as a side effect.
**Why Each Wrong Option is Incorrect**
**Option A:** **Ipratropium bromide** is an anticholinergic medication that is used as a bronchodilator in asthma. It works by blocking muscarinic receptors in the lungs, leading to bronchodilation. It is not typically associated with hoarseness of voice.
**Option B:** **Montelukast** is a leukotriene receptor antagonist that is used as an add-on therapy in asthma. It works by blocking the action of leukotrienes, which are pro-inflammatory mediators involved in the pathophysiology of asthma. It is not typically associated with hoarseness of voice.
**Option C:** **Ciclesonide** is an inhaled corticosteroid that is used as a maintenance therapy in asthma. It works by reducing inflammation in the lungs and is not typically associated with hoarseness of voice.
**Clinical Pearl / High-Yield Fact**
It's worth noting that **hoarseness of voice** is a common side effect of **β2-adrenergic agonists**, but it is often temporary and resolves once the medication is discontinued. However, if hoarseness persists or is severe, it may be a sign of an underlying condition that requires further evaluation.
**Correct Answer: C. Ipratropium bromide is not the correct answer, however, the question is asking for a drug that can lead to hoarseness of voice, in that case, all the options are incorrect as none of them are primarily associated with hoarseness of voice. However, considering the options, the best answer would be a drug that can cause hoarseness of voice. In that case, all the options are incorrect.
