Release form and composition
Dosage form Tussin plus - syrup: red-orange solution, transparent, with a slight cherry smell, without sediment and foreign particles (in a PET bottle 118 ml, in a cardboard box 1 bottle complete with a dosage cup).
Composition of Tussin plus (5 ml of syrup):
- active substances: guaifenesin - 100 mg, dextromethorphan hydrobromide - 10 mg;
- auxiliary components: citric acid, glycerol (anhydrous glycerin), flavoring agent, corn syrup, sodium saccharinate, sodium benzoate, levomenthol, cherry flavor, FD&C charming red dye, purified water.
Pharmacological properties
Pharmacodynamics
The expectorant effect of guaifenesin, the active component of Tussin plus, is due to the stimulation of secretory cells of the bronchial mucosa, producing neutral polysaccharides, depolymerization of acidic mucopolysaccharides, a decrease in viscosity and an increase in sputum volume, activation of the ciliary apparatus of the bronchi, facilitating the removal of sputum and facilitating the transition to an unproductive one.
Another active component of the drug, dextromethorphan hydrobromide, helps to suppress excessively intense afferent impulses from the mucous membrane of the respiratory tract, increase the cough threshold, and reduce the intensity of dry irritating cough. Due to the inhibition of the excitability of the cough center, dextromethorphan is able to suppress coughs of any origin. At the same time, the substance in therapeutic dosages does not have analgesic, narcotic and hypnotic effects.
The duration of the antitussive action is 5-6 hours.
Pharmacokinetics
After oral administration, after 25-30 minutes, guaifenesin is rapidly absorbed in the gastrointestinal tract. Its half-life (T 1/2) is 1 hour. The active substance is able to penetrate into tissues containing acidic mucopolysaccharides. Guaifenesin is metabolized in the liver. Excretion occurs through the lungs (with sputum) and in the form of inactive metabolites through the kidneys.
Dextromethorphan hydrobromide is rapidly absorbed from the gastrointestinal tract, after 15-30 minutes its effect begins to manifest itself. Metabolism occurs mainly with the participation of liver enzymes by O- and N-demethylation and partial binding with sulfates and glucuronic acid. In humans, (+) - 3-hydroxymorphinan, (+) - 3-hydroxy-1H-methylmorphinan and traces of an unmetabolized substance after oral administration can be observed in urine.
Indications for use
According to the instructions, Tussin plus is indicated for use in colds, flu, acute respiratory viral infections, accompanied by a cough.
Contraindications

- peptic ulcer of the stomach and duodenum;
- gastric bleeding (in history);
- severe organic diseases of the central nervous system;
- moist cough with profuse expectoration;
- concomitant use of drugs that include guaifenesin and / or dextromethorphan;
- children under 6 years old;
- increased individual sensitivity to any component in the composition of Tussin plus.
Relative (use of the drug requires caution):
- impaired renal and / or liver function;

Instructions for the use of Tussin plus: method and dosage
Tussin plus syrup is taken orally, after meals, using a dosage cup or teaspoon.

Side effects
During the period of treatment with the drug, the following side reactions may occur: nausea, vomiting, dyspeptic disorders, diarrhea, exacerbation of gastric and duodenal ulcers, headache, dizziness, insomnia or drowsiness, increased excitability (especially in children), allergic reactions in the form of skin rash, urticaria, hyperthermia.
Overdose
Especially high doses of guaifenesin can cause nausea and vomiting. In case of prolonged vomiting, it is necessary to carry out measures to replenish fluid in the body and control the level of electrolytes.
An overdose of dextromethorphan can lead to the development of dizziness, agitation, respiratory depression, impaired consciousness, decreased blood pressure, tachycardia, muscle hypertonicity, ataxia.
In case of an overdose of Tussin plus, gastric lavage, intake of activated charcoal, and symptomatic therapy are recommended.
special instructions
During the period of drug treatment, a sufficient amount of liquid should be taken.
During the application of Tussin plus, urine may turn pink.
When testing the content of 5-hydroxyindoleacetic acid in urine (using a nitrosonaphthol reagent), the result may be falsely overestimated due to the effect of guaifenesin metabolites on urine color. The drug must be discontinued 2 days before urine collection for this analysis.
Guaifenesin and its metabolites can also change color when determining the concentration of vanillyl mandelic acid in urine and cause a false overestimation of the results of the analysis with it for catechins. Stop taking guaifenesin 2 days before urine collection for this test.
A dosage cup is included with Tussin plus. One division of TSP equals 5 ml - one teaspoon.
Influence on the ability to drive vehicles and complex mechanisms
Since while taking the drug, side effects such as dizziness and drowsiness are possible, care must be taken when driving or performing any activities that require a quick psychomotor reaction and high concentration of attention.
