Drugs on Respiratory Upper/Lower
| Question | Answer |
|---|---|
| Drugs that block the release or action of histamine, a chemical released during inflammation that increase secretions and narrow airways. | antihistamines |
| drugs that block the cough reflex | antitussives |
| drugs that decrease the blood flow to the upper respiratory tract and decrease the overproduction of secretions | decongestants |
| drugs that increase productive cough to clear the airways | expectorants |
| drugs that increase of liquefy respiratory secretions to aid the clearing of the airways | mucolytics |
| a process that occurs when the nasal passages become congested as the effect of a decongestant drug wears off | rebound congestions |
| reflex reactions to vasoconstriction caused by decongestants: a rebound vasodialation that often leads to prolonged oveuse of decongestans: also called rebbound congestions | rhinitis medicatmentosa |
| medication used to facilitate respiration by dilating the airways: helpful in symptomatic relief of prevention of bronchial asthma and bronchospasm associated w/ chronic obstructive pulmonary disease | bronchodilator |
| drugs that selectively and competively block or antagonize receptors for the production of leukotrienes D4 and E4, components of slowreacting substance of anaphylaxis (SRSA)` | Leukotriene receptor antagonists |
| drug that works at the cellular level to inhibit the release of histamine (released from mast cells in response to inflammation or irritation) and the release of slow-reacting substance of anaphylaxis (SRSA) | mast cell stabilizer |
| drugs that mimic the effects of the sympathetic nervous system | sympathomimetics |
| naturally occurring susbstance, including caffeine and theophylline, that have a direct effect on the smooth muscle of the respiratory tract, both in the bronchi and in the blood vesels | xanthines |
