Abstract:
This study assessed the impact of high altitude residence during pregnancy on parameters of maternal immune and endocrine system function. Urinary catecholamines, and serum cytokines, estriol, and cortisol were assessed during pregnancy in women living at moderate or high altitude. Women residing at high altitude exhibited elevated levels of proinflammatory cytokines only during pregnancy, and tended to have higher levels of catecholamines during pregnancy than women living at lower altitude. These data suggest that the combination of high altitude and pregnancy alters the maternal neural-immune axis in a manner that may predispose women to suboptimal birth outcomes.

Upper 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 anesthetizing...
