Abstract:
We examined the eosinophil viability-enhancing activity (EVEA) of peripheral blood mononuclear cells (PBMNCs) obtained from mite-sensitive bronchial asthma (BA) and normal control subjects. Mite concentrations of 1 and 10 micrograms/ml significantly increased EVEA in BA patients as compared with normal controls (p < 0.05 and p < 0.05, respectively). The level of IFN-gamma in PBMNC culture supernatants was higher in BA patients than in normal controls. Dexamethasone, cyclosporin A and FK506 significantly inhibited EVEA in BA patients (p < 0.05 to p < 0.001).

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...
