Chlor Trimeton Decongestant
Chlor Trimeton Decongestant Uses, Dosage, Side Effects, Food Interaction and all others data.
Chlor Trimeton Decongestant is structurally related to ephedrine but exerts a weaker effect on the sympathetic nervous system. Both drugs naturally occur in in ephedra plant which have a history of use in traditional Eastern medicine and were first researched in the west in 1889. The decongestant effect of pseudoephedrine was described in dogs in 1927.
Chlor Trimeton Decongestant causes vasoconstriction which leads to a decongestant effect. It has a short duration of action unless formulated as an extended release product. Patients should be counselled regarding the risk of central nervous system stimulation.

Uses
Chlor Trimeton Decongestant is an alpha and beta adrenergic agonist used to treat nasal and sinus congestion, as well as allergic rhinitis.
Chlor Trimeton Decongestant is a sympathomimetic amine used for its decongestant activity.

How Chlor Trimeton Decongestant works
Chlor Trimeton Decongestant acts mainly as an agonist of alpha adrenergic receptors and less strongly as an agonist of beta adrenergic receptors.[A10896] This agonism of adrenergic receptors produces vasoconstriction which is used as a decongestant and as a treatment of priapism. Chlor Trimeton Decongestant is also an inhibitor of norepinephrine, dopamine, and serotonin transporters.
The sympathomimetic effects of pseudoephedrine include an increase in mean arterial pressure, heart rate, and chronotropic response of the right atria. Chlor Trimeton Decongestant is also a partial agonist of the anococcygeal muscle. Chlor Trimeton Decongestant also inhibits NF-kappa-B, NFAT, and AP-1.
