Respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD) are commonly treated with β2-adrenergic receptor agonists that activate intracellular signaling pathways to induce airway relaxation. However, current therapies are limited by progressive receptor desensitization, or tachyphylaxis, largely attributed to β-arrestin recruitment. This desensitization reduces therapeutic efficacy over time and complicates long-term disease management, resulting in suboptimal outcomes for patients who rely on bronchodilators for daily symptom control. Disclosed herein are pharmaceutical compositions comprising biased agonists and their methods of use, which minimally activate recruitment of beta-arrestin2.
