Description

One tablet contains

  • Active ingredient – Cytisine (in terms of 100% substance)
  • Excipients: lactose monohydrate, microcrystalline cellulose (type 102), talc, magnesium stearate.

 

Pharmacological properties

Cytisine is readily absorbed from the gastrointestinal tract when taken orally.

The maximum plasma concentration, which is about 15.55 ng / ml, is reached within 0.92 hours.

Cytisine does not undergo significant metabolic transformation. 64% of the dose taken is excreted unchanged by the kidneys within 24 hours. The half-life is approximately 4 hours. The average retention time for cytisine is about 6 hours.

Cytisine is an alkaloid isolated from the plant Cytisus Laburnum.

Its chemical structure is similar to nicotine and lobelin. Selectively and competitively binds to n-cholinoneuroreceptors, blocks the ability to connect to these nicotine receptors, thus showing the properties of a nicotine antagonist. As a result of the action of these drugs, nicotine loses its ability to stimulate n-cholinergic receptors and activate the dopamine system – the mechanism that underlies the formation of tobacco dependence (enjoyment from nicotine). As a result of this action, the symptoms of nicotine addiction gradually decrease and disappear. Other pharmacodynamic properties of cytisine: excites the ganglia of the autonomic nervous system, reflexively excites respiration, causes the release of adrenaline from the medullary part of the adrenal gland, increases anterior pressure.

 

Indications for use

Chronic nicotinism (tobacco) – to quit smoking.

Drug Interactions

When smoking, an increase in CYP1A2 activity is observed. After smoking cessation, the activity of this isoenzyme may be reduced, which may cause an increase in plasma concentrations of drugs that are metabolized with the participation of CYP1A2, such as theophylline, ropinirole, clozapine and olanzapine. In these cases, their side effects may increase, since these drugs have a small therapeutic breadth.

With the simultaneous use of Tabex® with cholinomimetics, including anticholinesterase drugs, cholinomimetic side effects may increase.

Simultaneous use with antihyperlipidemic drugs (statins) increases the risk of myalgia.

The simultaneous use of Tabex® with antihypertensive drugs may weaken their effect.

 

Special instructions

Tabex® should only be prescribed when the patient has a serious intention to quit smoking. Treatment with the drug and continued smoking can lead to an increase in the side effects of nicotine (nicotine intoxication).

There is not enough clinical experience with the use of Tabex® in patients with other forms of coronary heart disease, heart failure, arterial hypertension, cerebrovascular disease, obliterating arterial diseases, hyperthyroidism, peptic ulcer, diabetes mellitus, renal or hepatic insufficiency. The use of Tabex® in these patients should occur after careful evaluation by the attending physician.

Due to the lack of safety studies of the drug in patients with some forms of schizophrenia, patients with adrenal chromaffin tumors and gastroesophageal reflux disease, the use of cytisine in such cases should be after a thorough assessment of the benefit / risk ratio.

There is not enough clinical experience regarding the safe use of Tabex® in children under 18 years of age and in adults over 65 years of age, as a result of which its use in these age groups is not recommended.

The medicinal product contains the excipient lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not use the drug.
