— Explanation · 中文詳解 —
Propranolol 屬於非選擇性乙型阻斷劑(Non-selective Beta-blocker)。它會阻斷支氣管平滑肌上的 β2 受體,導致支氣管收縮,進而誘發氣喘發作或惡化。對於有氣喘史的病人,這類藥物屬於禁忌或需謹慎使用的藥物。其餘選項皆為治療氣喘的常見藥物。
Propranolol is a non-selective beta-blocker. It blocks the β2-receptors on bronchial smooth muscle, causing bronchoconstriction and thereby precipitating or worsening an asthma attack. In patients with a history of asthma, this class of medication is contraindicated or must be used with caution. The other options are all common medications used in the treatment of asthma.
