Metabolite Identification
Common NameTymazoline
DescriptionTymazoline is only found in individuals that have used or taken this drug. It is a nasal preparation.Thymazen causes vasoconstriction of the nasal mucosa, reducing congestion and thus the swelling of the mucosa. Also reduces the secretions from the nose. Thymazen acts on alpha-adrenergic receptors, which reduces local inflammation of the nasal mucosa especially if their cause is an allergy.
