Tylenol Allergy Sinus Geltab Chemical Information

acetaminophen - An acetanilide with analgesic and antipyretic activity. Although the exact mechanism through which acetaminophen exert its effects has yet to be fully determined, this agent probably acts by inhibiting prostaglandin synthesis in the central nervous system (CNS). Inhibition of prostaglandin synthesis in the CNS results in elevation of the pain threshold and lowering of the thermal set point in the hypothalamus.

chlorpheniramine maleate - A synthetic alkylamine derivative used in allergic reactions, hay fever, rhinitis, urticaria, and asthma, antihistamine Chlorpheniramine Maleate acts as a competitive histamine H1 receptor antagonist, and displays anticholinergic and mild sedative effects as well. (NCI04)

pseudoephedrine hydrochloride - The hydrochloride salt form of pseudoephedrine, a phenethylamine and an diastereomer of ephedrine with sympathomimetic property. Pseudoephedrine hydrochloride displaces norepinephrine from storage vesicles in presynaptic neurones, thereby releasing norepinephrine into the neuronal synapses where it stimulates primarily alpha-adrenergic receptors. It also has weak direct agonist activity at alpha- and beta- adrenergic receptors. Receptor stimulation results in vasoconstriction and decreases nasal and sinus congestion.
