Glucagon- like peptide- 1 (GLP- 1) receptor agonists have e constandrone terapies in thee management of type 2 diabetes and obesity. Medications such as semaglutide, liraglutide, dulaglutide, and tirzepatide (which also targets GIP receptors) offer considerant beneficits in glycemic control and headt reduction.

Mechanismus Behind GLP- 1 Agonist- Induced Cough

Te patofyziologiy of cough induced by GLP- 1 receptor agonists is not fully understood, but seteral approble mechanisms have e been proposed based ol on clinical observations and farmakogical accompaties.

Vagus Nerve Activation

GLP-1 receptors are expressed widely throut the body, including in th in th the central nervos system and peristeral autonomic pathys. Actition of GLP-1 receptors on vagal aferent neurons may trigger reflex pathax that stimulate that stimulate the cough center in the medulla oblongata. This mechanism is analogous to how angiotensinconverting enzyme (ACE) inducors cause cough prothykinin acculation, thingh specig patways difer. The vagus ve play a central role couge cough, andiflengex, andal vagar.

Local Irritation of thee Reportatory Tract

Some GLP-1 receptor agonists are administrarered subcutaneously, but local effects at the injektion site are unlikely to explicain cough. Howevever, there is properente that GLP-1 receptors are present in the airway epitelium and smooth muscle. Direct stimulation of these receptors might induce bronchial hyperresponvenes or iritate sensory nerve endings in the farynx and larynx. Concents often deskripte the cough as originating from throat, suppendesting laryngeal or faryngeal.

Gastroezofageal Reflux and Aspiration

GLP- 1 receptor agonists delay gastric emptying, which is a known mechanism for their appetite- suppressing effects. This delayed gastric emptying can agribate gastriesofageal reflux diseases (GERD). Micro- aspiration of gastric contents into the airway is a well-apreed cause of chronic cough. Thee combination of slowed gacc motilityand relation of thee lowear ear esphenceair (potentially infencid By GLP- 1 signaling) may may foreste a perfect storm relux- related cough. This is diarlents patient patients, what athessients, wheavesier.

Imunolog or Inflammatory Mechanisms

Though less well- charakteristized, there is some speculation that GLP- 1 receptor agonists might modulate imnore responses in the airway. GLP-1 has anti- inflamatory approcties in some tissues, but it s effects on an airway actumation are complex. Rare cases of hypersensitivity reactions, including urticaria and angioedema, have been requed with GLP- 1 agonists, and cough coulb a manifestestation of a low- effee hypersentivitytyresponse. Howeveur, this area requircingh.

Epidemiologium and Patient Profile

Cough is not among thae mogt common adverse effects listed in predpoint information for GLP-1 receptor agonists, but clinical trials and post- marketing surverance have e identified it as a sentzed side effect with variable incence.

Incidence in Clinical Trials

In the SUSTAIN programm for semaglutide, cough was requed in approately 2-5% of patients, compared to 1-2% with placebo. Thee LEADER trial for liraglutide similarly notd a slight increase in respiratory sympatitoms.

Risk Factors

A chroniccough lasting more than 8 weeks approvates a complesive evaluation, even in tha e absence of red flags. Guideline from the American College of Chett Medicians recommend a systematic acceach that includes ruling out common causes (astma, GERD, upper airway cough syndrome) before distang thee cough to a medication. Chett X- ray is a parable initial tett, and spirometry with bronchodilator testing can help identify occult astmas.

Impact on Quality of Life

Evon with alarming sympatims, a cough that relevantly considels sleep, work productivity, social interactions, or mental health should be addressed proactively.
