-
Antitussives
Dextromethorphan (Benylin)
- Control of non-productive cough.
- Acts directly on the medullary cough center of the brain to depress cough reflex. CNS Depression. Side effects-drying effect on mucous membranes. Can increase viscosity of resp. tract secretions. Drowsiness. Do not use with MAOI r/t hypotension.
-
Topical Nasal Decongestants
Ephedrine (Pretz-D)
Sympathemimetics (imitate the effects of the SNS to cause vasoconstriction). Risk of rebound. Not with glaucoma, hypertension, DM, thyroid disease, CAD, BPH).Relieve congestion, swelling, and inflammation by contricting arterioles-decreases blood flow to nasal mucosa.
-
Oral Decongestant
Pseudoephedrone (sudafed, Decofed)
- Promote drainage of the sinuses and improve air flow. Risk of Rebound.
- Shrinks the nasal mucous membrane by stimulating the Alpha-Adrenergic receptors in the nasal mucous membrane. Adverse effects r/t sympathomimetic effects (anxiety, hypertension, arrhythmias. Found in many OTC meds.
-
Topical Nasal Steroid Decongestants
Flunisolide (Aerobid)
- Maintenance treatment of asthma.
- Potent locally acting anti-inflammatory and immune modifier. For chronic not acute inflammation. Caution with active infection like TB.
-
Antihistamines-1st gereration:
Diphenhydramone (Benadryl), Hydroxyzone (Vistarel)
- Relief of seasonal/perennial allerigic rhinitis, allergic conjunctivitis, uncomplicated uritcaria and angioedema.
- Selectively blocks the effect of histamine at the histamine receptor sites, decreases the allergic response also have anticholinergic and antipruritic effects. Side effects-drowsiness, anticholinergic-SLUD
-
Expectorants
Guiafenesin (Mucinex)
- Enhances the output of respiratory tract fluid by reducing the adhesivness and surface tension of the fluid facilitating the removal of viscous mucus.
- Do not use for more than 1 week.
- Increase fluids.
-
Mucolytics (Muco=mucous, lytic=breakdown)
Acetylcysteine (Mucomyst), Dornase Alfa (Pulmozyme)
- Pts with difficulty coughing up tenacious secretions who develop atelectasis undergoing bronchoscopy, pt with trachs, and post operative pts.
- Works to breakdown mucus in order to aid the high-risk pt (cystic fibrosis) in coughing up thick secretions.
- Inhaled mucomist could put pt into bronchospasm-not safest!
