Тримекс

Тримекс Uses, Dosage, Side Effects, Food Interaction and all others data.

Тримекс 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 Currently, it is withdrawn from the market in Canada and the United States due to the risk for hemorrahgic strokes.

Тримекс (PPA), a sympathomimetic agent structurally similar to pseudoephedrine, is used to treat nasal congestion. Тримекс 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.

Uses

Тримекс is a sympathomimetic that was previously used in nasal decongestants and weight loss products, but has been withdrawn by the FDA due to safety risks and lack of efficacy.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.

Тримекс is also used to associated treatment for these conditions: Allergy-Induced Respiratory Symptoms, Bronchitis, Common Cold, Cough, Nasal Congestion, Rhinorrhoea, Excess mucus or phlegm

How Тримекс works

Тримекс 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.

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)

Food Interaction

Limit caffeine intake.
Take with or without food. The absorption is unaffected by food.

[Moderate] GENERALLY AVOID: Alcohol may potentiate the central nervous system and cardiovascular effects of centrally-acting appetite suppressants.

In one study, concurrent administration of methamphetamine (30 mg intravenously) and ethanol (1 gm

This increases cardiac work and myocardial oxygen consumption, which may lead to more adverse cardiovascular effects than either agent alone.

Subjective effects of ethanol were diminished in the eight study subjects, but those of methamphetamine were not affected.

The pharmacokinetics of methamphetamine were also unaffected except for a decrease in the apparent volume of distribution at steady state.

MANAGEMENT: Concomitant use of centrally-acting appetite suppressants and alcohol should be avoided if possible, especially in patients with a history of cardiovascular disease.

Patients should be counselled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
