expectorants
|
drugs that liquefy and dilute viscid secretions of the respiratory tract and help evacuate secretions
|
|
|
guaifenesin
|
expectorant used to relief cough symptoms related to URI conditions
|
|
|
mucolytic
|
decrease viscosity of respiratory secretions by altering chemical composition of mucus through breakdown of chemical bonds
|
|
|
acetylcysteine
|
mucolytic
used to break down thick of inspissated respiratory mucus or to treat acetaminophen toxicity |
|
|
antitussive
|
drugs that inhibit or suppress coughing by depressing the cough center in the brain or cough receptors in the airways
|
|
|
butorphanol tartrate
|
antitussive and opiate agonist
|
|
|
hydrocodone bitartrate
|
antitussive and opiate agonist
|
|
|
codeine
|
opiate agonist and atitussive
|
|
|
dextromethorphan
|
nonnarcotic antitussive used to supress nonproductive cough
|
|
|
temaril-p
|
contains trimeprazine tartrate-antitussive- and prednisolone-corticosteroid
antitussive and antipruritic |
|
|
bronchodilators
|
composed of either
cholinergic blockers antihistamines beta-2-adrenergics or methylxanthines |
|
|
cholinergic blockers
|
produce bronchodilation by combinging with acetylcholine receptors on smooth muscle fibers and preventing bronchoconstricting effects of acetylcholine
|
|
|
beta-2-adrenergic agonists
|
combine with appropriate receptors on smooth muscle fibers and effect relaxation of those fibers
ex.epinephrine isoproterenol albuterol |
|
|
methylxanthines
|
used therapeutically
inhibit an enzyme in smooth muscle cells called phosphodiesterase and promote bronchodilation ex. aminophylline and theophyllinee |
|
|
decongestants
|
drugs that reduce the congestion of nasal membrane by reducing associated swelling
ex. ephedrine, pseudoephedrine, phenylpropanolamine, oxymetazoline, phenylephrine |
|
|
antihistamines
|
used to block the effects of histamine and promote bronchodilation
ex. pyrilamine, tripelennamine, probahist, diphenhydramine, doxylamine, hydroxyzine, terfenadine, clemastine, cyproheptadine |
|
|
corticosteroids
|
used primarily in treatment of allergic respiratory conditions
have a strong antiinflammatory effect when absorbed into general circulation ex. prednisolone sodium succinate, prednisolone, dexamethasone, triamcinolone |
|
|
naloxone
|
used to stimulate respirations in narcotic overdose
|
|
|
yobine
|
used to stimulate respirations in xylazine overdose
|
