Glucagon demonstrated a significant bronchodilator effect in asthma patients, improving FEV1 and peak expiratory flow rates. This suggests glucagon may be a viable treatment option for select individuals with asthma.
Area of Science:
- Pulmonology
- Pharmacology
Background:
- Asthma is a chronic respiratory disease characterized by airway inflammation and bronchoconstriction.
- Current asthma treatments primarily focus on bronchodilators and anti-inflammatory agents.
Purpose of the Study:
- To investigate the potential bronchodilator effects of glucagon in patients with asthma.
- To assess the efficacy of intravenous glucagon compared to a placebo in improving lung function parameters.
Main Methods:
- A double-blind, crossover study was conducted on eight asthma patients.
- Patients received either intravenous glucagon or saline after a 12-hour bronchodilator washout period.
Main Results:
- Glucagon significantly improved FEV1 (17.5%) and peak expiratory flow rate (14.2%) compared to placebo.
- Seven out of eight patients showed a notable response to glucagon, with improvements ranging from 40% to 105% of isoproterenol response.
Conclusions:
- Intravenous glucagon exhibits a bronchodilator effect in selected asthma patients.
- Glucagon's pharmacologic actions may offer a therapeutic benefit for certain individuals with asthma.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
