PN 2005-Respiratory Drugs Overview Exam
Questions With 100% Verified Correct Answers.
Antitussives
Drugs that suppress the cough reflex by acting on the medullary cough center or respiratory
passages
Decongestants
Medications that reduce nasal congestion by causing vasoconstriction and decreasing blood flow
