Drug of choice for managing asthmatic patient with hypeension: March 2009
**Core Concept**
Asthma is a chronic inflammatory disease of the airways, and managing patients with asthma requires careful consideration of their underlying medical conditions, including hypertension. In this scenario, the goal is to select a medication that effectively controls asthma symptoms while minimizing the risk of exacerbating hypertension.
**Why the Correct Answer is Right**
Theophylline is a methylxanthine bronchodilator that can help manage asthma symptoms by relaxing smooth muscle in the airways and increasing the levels of cyclic adenosine monophosphate (cAMP) within airway smooth muscle cells. However, it is not the first-line treatment for asthma due to its narrow therapeutic index and potential side effects. Theophylline is often used as an add-on therapy in patients with severe asthma who are not adequately controlled with inhaled corticosteroids and bronchodilators.
**Why Each Wrong Option is Incorrect**
**Option A:** is not specified, so we'll assume it's a common asthma medication like fluticasone or salmeterol. These medications are effective for managing asthma symptoms but do not address hypertension directly.
**Option B:** could be a beta-blocker, which is generally contraindicated in asthma due to its ability to induce bronchoconstriction by blocking beta-2 adrenergic receptors in the airways.
**Option C:** could be a corticosteroid, which is a common treatment for asthma but does not directly address hypertension.
**Option D:** could be a leukotriene modifier, which is a type of asthma medication that can help control symptoms but does not directly address hypertension.
**Clinical Pearl / High-Yield Fact**
When managing patients with asthma, it's essential to consider their underlying medical conditions and potential interactions between medications. In this case, theophylline may be a suitable option for managing asthma symptoms in patients with hypertension, but it requires careful monitoring due to its narrow therapeutic index.
