Nasal Decongestants and Respiratory Enzymes

  1. Pseudoephedrine
    (Afrinol and Drixoral)-extended release
    Class: Aryalkylamines
    • No longer OTC
    • Indications:Oral-temporary relief of nasal congestion due to common cold, hay fever, or other UR allergies, sinusitis, relief of eustachian tube congestion. Topical- symtomatic relief of nasal and nasopharyngeal mucosal congestion, adjunctive therapy of otitis media, may be useful in air travel to decrease ear block and pressure pain

    • MOA: Sympathomimetic amines
    • stimulates alpha1-adrenergic receptors of the cascular smooth muscle predominately, although ephedrine and pseudophedrine have Beta-adrenergic properties

    Side effects: contraction of the GI and Urinary sphincters, mydriasis, decreased insulin secretion

    contraindicated: patients taking MAOI, idiosyncratic dizziness, weakness, tremor or arrhythmias

    Can develop tolerance

    Many dI: B-blockers, MAO inhibitors, guanethidine phenylpropanolamine use concurrently with indomethacin can lead to hypertension

    must sniff hard
  2. Phenylephrine HCl (Neo-Synephrine)
    Class: Aryalklamines
    • replaces pseudoephedrine as OTC
    • can jack up blood pressure


    Indications:Oral-temporary relief of nasal congestion due to common cold, hay fever, or other UR allergies, sinusitis, relief of eustachian tube congestion.

    must sniff hard
  3. Tetrahydrozoline (Tyzine)
    Class: Imidazolines
    • limited CNS access
    • Partial agonist of Alpha 1 and alpha 2 adrenergic receptors

    Indications:Oral-temporary relief of nasal congestion due to common cold, hay fever, or other UR allergies, sinusitis, relief of eustachian tube congestion. Topical- symtomatic relief of nasal and nasopharyngeal mucosal congestion, adjunctive therapy of otitis media, may be useful in air travel to decrease ear block and pressure pain

    contraindicated: patients taking MAOI, idiosyncratic dizziness, weakness, tremor or arrhythmias

    Can develop tolerance

    Many dI: B-blockers, MAO inhibitors, guanethidine phenylpropanolamine use concurrently with indomethacin can lead to hypertension

    must sniff hard
  4. Oxymetazoline (Visine)
    Class: Imidazolines
    • Primary use: ophthalmic use
    • linked to septal erosion when used chronically  


    Indications:Oral-temporary relief of nasal congestion due to common cold, hay fever, or other UR allergies, sinusitis, relief of eustachian tube congestion. Topical- symtomatic relief of nasal and nasopharyngeal mucosal congestion, adjunctive therapy of otitis media, may be useful in air travel to decrease ear block and pressure pain

    • MOA: Sympathomimetic amines

    must sniff hard
  6. Human alpha 1-Proteinase Inhibitor (Prolastin injection)
    Purified from large pools of human plasma

    Indications: Congenital alpha1-antitrypsin deficiency expressing as panacinar emphysema

    Antitrypsin deficiency is chronic hereditary, usually fatal autosomal recessive disorder involving abnormally low concentrations of inhibitors--it leads to emphysema in the 3rd-4th decade

    MOA: replacement of naturally deficient inhibitor
