43
Antihistamines
Upper respiratory, decreased histamine at H1 receptor, decreasing allergic response; Anticholinergic and antipruritic effects; more sedation with 1st gen
44
Expectorants
Upper respiratory, increased output of respiratory tract fluids by decreasing adhesiveness and surface tension leading to easier movement; Less sticky = easier to cough up
45
Mucolytics
Upper respiratory, BREAKDOWN mucous to aid high risk respiration patient cough up thick and tenacious secretions
46
Xanthines
