Phenylpropanolamine is a sympathomimetic agent that acts as a nonselective adrenergic receptor agonist and norepinephrine reuptake inhibitor. It has been used as a decongestant and appetite suppressant. Currently, it is withdrawn from the market in Canada and the United States due to the risk for hemorrahgic strokes.
Phenylpropanolamine (PPA), a sympathomimetic agent structurally similar to pseudoephedrine, is used to treat nasal congestion. Phenylpropanolamine is found in appetite suppressant formulations and with guaifenesinin in cough-cold formulations. In 2000, the FDA requested that all drug companies discontinue marketing products containing phenylpropanolamine, due to an increased risk of hemorrhagic stroke in women who used phenylpropanolamine.
First generation histamine H1 antagonist used in allergic rhinitis; asthma; and urticaria. It is a component of cough and cold medicines. It may cause drowsiness.
In allergic reactions an allergen interacts with and cross-links surface IgE antibodies on mast cells and basophils. Once the mast cell-antibody-antigen complex is formed, a complex series of events occurs that eventually leads to cell-degranulation and the release of histamine (and other chemical mediators) from the mast cell or basophil. Once released, histamine can react with local or widespread tissues through histamine receptors. Histamine, acting on H1-receptors, produces pruritis, vasodilatation, hypotension, flushing, headache, tachycardia, and bronchoconstriction. Histamine also increases vascular permeability and potentiates pain. Triprolidine, is a histamine H1 antagonist that competes with histamine for the normal H1-receptor sites on effector cells of the gastrointestinal tract, blood vessels and respiratory tract. It provides effective, temporary relief of sneezing, watery and itchy eyes, and runny nose due to hay fever and other upper respiratory allergies. Triprolidine has anticholinergic and sedative effects.

Uses
Phenylpropanolamine is a sympathomimetic that was previously used in nasal decongestants and weight loss products, but has been withdrawn by the FDA due to safety risks and lack of efficacy.
For the treatment of nasal congestion, control of urinary incontinence, priapism and obesity.
Triprolidine is a sedating antihistamine combined with pseudoephedrine and guaifenesin in various types of cold and allergy medications to relieve allergy symptoms, hay fever and common cold symptoms, and to aid in sleep.
For the symptomatic relief of seasonal or perennial allergic rhinitis or nonallergic rhinitis; allergic conjunctivitis; and mild, uncomplicated allergic skin manifestations of urticaria and angioedema. Also used in combination with other agents for the symptomatic relief of symptoms associated with the common cold.
Actiflu Plus is also used to associated treatment for these conditions: Allergy-Induced Respiratory Symptoms, Bronchitis, Common Cold, Cough, Nasal Congestion, Rhinorrhoea, Excess mucus or phlegmNasal Congestion, Perennial Allergic Rhinitis (PAR), Seasonal Allergic Conjunctivitis, Seasonal Allergic Rhinitis, Upper respiratory tract signs and symptoms, Vasomotor Rhinitis, Mild Angioedema, Mild urticaria, Upper respiratory discomfort
How Actiflu Plus works
Phenylpropanolamine acts directly on alpha- and, to a lesser degree, beta-adrenergic receptors in the mucosa of the respiratory tract. Stimulation of alpha-adrenergic receptors produces vasoconstriction, reduces tissue hyperemia, edema, and nasal congestion, and increases nasal airway patency. PPA indirectly stimulates beta-receptors, producing tachycardia and a positive inotropic effect.
Triprolidine binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.
Toxicity
May induce ventricular extrasystoles and short paroxysms of ventricular tachycardia, a sensation of fullness in the head and tingling of the extremities; LD50=1490mg/kg (orally in rat)
Symptoms of overdose include drowsiness, weakness, inco-ordination, difficulty with micturition, respiratory depression, hypotension, agitation, irritability, convulsions, hypertension, palpitation and tachycardia.
Elimination Route
Reduced bioavailability (about 38%) from gastrointestinal tract because of first pass metabolism by monoamine oxidase in the stomach and liver.
Rapidly absorbed in the intestinal tract.
Half Life
2.1 to 3.4 hours.
4 to 6 hours.
