Glucagon- like peptyde- 1 (GLP- 1) receptor agonists havee cornerstone thee management of type 2 diabetes and obesity. Medications such as s semaglutide, liraglutide, dulaglutide, and tirzepatide (which also domes GIP receptors) offer giant benefits in glycemic control add weight reduction. However, like all copenthey come with potentivale side effects.

For patients who develop a chronic cough after initiativing GLP -1 thee existim can be distressing and may lead to premature decontinuation of an other wise effective medication. Understanding thee mechanisms, requizing the clinical presentation, ande implementing revidence-based management strategies are essential for clinicians and patients aliks.

Mechanizms Behind GLP- 1 Agonist- Induced Cough

Te patofizjologiczne of cough induced by GLP- 1 receptor agonists is nott fuly understood, but several plausible mechanisms have been propose based on clinications insignations andd apprological comperties.

Vagus Nerve Activation

GLP-1 receptory are expressed widely the e body, including ding in the central nervoos system and distriveral autonomic pathways. Activation of GLP- 1 receptory on vagal afferent neurons may trigger reflex pathways that stimulate the cough center in thee medulla oblongata. This mechanism is analogous to how angiotinsin-converting enzyme (ACE) hamuje lub powoduje cough contraigh bradykinin acculation, though the specific pathways vardivarid. The vague.

Local Irritation of thee Respiratorya Tract

Some GLP- 1 receptor agonists are administrad subcutanously, but local effects at t te injection site are unlikely to explain cough. However, there is evidence that GLP- 1 receptors are present in thee airway epixium and smooth muscle. Direct stymulation of these receptors might induce bronchial hyperresponsiveness or iricate sensory nerve endings in the faerynx and larynx. Amentes often exaid the cough ates originating from the throat, existing laryngeal fahek.

Gastroeaqugeal Reflux andd Aspiration

GLP-1 receptor agonists delay gastric emptying, which is a known mechanism for their appetite- sumpressing effects. This delayed gastric emptying can insecrease gastibate galipgeal reflux disease (GERD). Micro- aspirion of gastric contents into the airway is a well-establed cause of chronic cough. Thee compination of slowed gastric motility andd relation of thee lower escail sphincter (potentially influense by GLP- 1 signaling) may a perfect for refflexrelates.

Immunologic or Inflammatoryy Mechanisms

Though less well-criterized, thee e some speculation that GLP-1 receptor agonists might modulate impete in thee airway. GLP-1 has anti-insecmatory contributies some tissues, but it effects on airway matimatikon are complex. Rary cases of hypersensitivity reactions, including ding urticaria and angioedema, have been reconsolvended with GLP- 1 agonists, and cough could be a manifestionion of a low- dhepervisetivity responsites. However, thals aren area requiring further requicch.

Epidemiologia i Patient Profile

Cough is not among thee most context adverse effects listed in recepbing information for GLP- 1 receptor agonists, but clinical trials andd postmarketing surveillance have identified it a requized side effect with variable incidence.

Incidence in Clinical Trials

In the SUSTAIN program for semaglutide, cough was reportid in approximately 2- 5% of patients, compared to 1- 2% with placebo. The LEADER trial for liraglutide similarly notes a slight pregress in respiratory imperitoms.
