Objective:
To determine the effectiveness of nortriptyline and tolerability of side effects in the treatment of neurogenic cough. Secondary goal is to evaluate the association between laryngeal asymmetry and clinical response to nortriptyline.
Study Design:
Retrospective case series.
Materials And Methods:
Consecutive patients diagnosed with neurogenic cough at a quaternary care specialty hospital from 2001 to 2020 were identified. Subjects <18 years old, not treated with nortriptyline, did not have a nasolaryngoscopic examination and were lost to follow-up were excluded. Charts were reviewed for demographic information, clinical history, nasolaryngoscopic findings, medication dosage, side effects, and follow-up time.
Results:
Forty-two patients met inclusion and exclusion criteria, 7 males and 35 females with an average age of 56.5 (±13.1) years. There were 26/36 (72.2%) responders and 10/36 (27.8%) non-responders; 6 patients stopped nortriptyline due to side effects and were not included in the response comparison. Laryngeal asymmetry was present in 36/42 (85.7%) patients. No factors related to laryngeal asymmetry were significantly different between responders and non-responders. Medication tolerance was observed in 3/42 (7.1%) patients. Side effects were reported in 16/42 (38.1%) patients. The most common side effects were sedation 9/42 (21.4%) and xerostomia 3/42 (7.1%).
Conclusion:
Nortriptyline is effective for treating neurogenic cough with 72% of patients reporting improvement in cough. Evidence of laryngeal asymmetry was not associated with better treatment response. Although 38% experienced side effects, the majority of patients continued nortriptyline despite side effects.
Level Of Evidence:
4.

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
01:23Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
