Teraflu is a complex medicine used for colds or flu. It demonstrates high efficiency in the development of swelling, allergies, fever and pain of various origins in the patient.
The drug has a pronounced antitussive, antipyretic, vasoconstrictor, sedative, analgesic, antihistamine and bronchodilating effect. Due to the therapeutic effect of Teraflu, the intensity of manifestations of acute respiratory infections, as well as colds, is significantly reduced.
Release form
The drug is released in the form of a lyophilisate for the production of oral liquid.
Pharmacodynamics
The effect of phenylephrine hydrochloride leads to a decrease in hyperemia of the nasopharyngeal mucous membranes, paranasal sinuses and nasal cavity. In addition, the substance weakens local exudative symptoms, reduces edema and narrows the vascular lumen.
Pheniramine maleate exhibits antiserotonin, antihistamine, sedative, and weak cholinolytic activity; this substance blocks the activity of histamine H1 endings. The effect of the component leads to the elimination of edema and hyperemia of the mucous membranes, to the narrowing of the vascular lumen, the suppression of sneezing, rhinorrhea, eye and nasal itching, and also to a decrease in the intensity of allergy symptoms.
Paracetamol is a non-narcotic analgesic that has antipyretic, analgesic and mild anti-inflammatory effects.

The effect of Theraflu begins to develop 20 minutes after drinking the liquid; the duration of the effect is up to 4.5 hours.

Along with this, intoxication with Theraflu causes agitation, sleep disorders, dizziness, convulsive syndrome, depressive mood and coma.
Symptomatic treatment measures are carried out. Gastric lavage, acetylcysteine, methionine, and SH-category donors are used. Gastric lavage is performed to prevent late hepatotoxic effects.
Interactions with other drugs
The medication potentiates the effects of sedatives, ethyl alcohol and MAOIs.
Antipsychotics, antiparkinsonian agents, phenothiazines and antidepressants significantly increase the risk of developing negative symptoms (such as urinary retention, constipation and dry mouth).
The use of GCS significantly increases the likelihood of developing glaucoma.
MAOIs and furazolidone in combination with chlorphenamine lead to the development of agitation, hyperpyrexia and hypertensive crisis.
The effect of paracetamol weakens the activity of uricosuric drugs.
The use of halothane leads to ventricular arrhythmia; tricyclics potentiate the sympathomimetic effect of Theraflu.
