What drug class blocks the action of acetylcholine and dries secretions?
anticholinergic agents - atrovent (ipatropium bromide) and spiriva (triotropium bromide)
What two classifications of bronchodilators relax airway smooth muscle

What classification of drug works to suppress the cough center in the brain and is used for bothersome dry, non-productive coughs?
Antitussive agents
People already receiving anti-hypertensive agents should avoid this classification of respiratory drugs
decongestants (sudafed, neo-synephrine, afrin) - They stimulate alpha adrenergic centers and can have hypertension as a side effect.
This drug is given for symptomatic relief of dry, nonproductive cough and removal of mucus plugs and may cause gastrointestinal upset

Do not use this antitussive agent in people with COPD as it can cause respiratory depression
Codeine
