моксонидин канон Medicine

Overdose

Coated tablet; Film-coated tablet; Substance-powderPowder for oral suspension

Symptoms of overdose

In the few cases of overdose that have been reported, a dose of 19.6 mg was ingested acutely without fatality. Signs and symptoms reported included: headache, sedation, somnolence, hypotension, dizziness, asthenia, bradycardia, dry mouth, vomiting, fatigue and upper abdominal pain. Based on the pharmacodynamic properties of Моксонидин Канон, the following reactions may be expected in adults: headache, sedation, somnolence, hypotension, orthostatic dysregulation, dizziness, asthenia, bradycardia, dry mouth, fatigue and upper abdominal pain. In rare cases, emesis and a transient paradoxical increase in blood pressure can occur. In case of a severe overdose close monitoring of especially consciousness disturbances and respiratory depression is recommended.

In addition, based on a few high dose studies in animals, transient hypertension, tachycardia and hyperglycaemia may also occur.

Treatment of overdose

In the case of a severe overdose, in particular the observation of disorders of consciousness and respiratory depression is advisable. Treatment consists of absorption-reducing measures such as gastric lavage (if shortly after ingestion), administration of activated charcoal and laxatives, and otherwise is symptomatic.

No specific antidote is known.

In case of hypotension, circulatory support such as fluids and dopamine administration may be considered. Bradycardia may be treated with atropine. Alpha-receptor antagonists may diminish or abolish the paradoxical hypertensive effects of a Моксонидин Канон overdose.

Paediatric population

The following case of inadvertent overdose in a 2-year old child has been described:

The child ingested an unknown quantity of Моксонидин Канон. The maximum dose that could have been taken was 14 mg. The child exhibited the following symptoms: Sedation, coma hypotension, miosis and dyspnoea. Gastric lavage, glucose infusions, mechanical ventilation and rest resulted in the symptoms completely disappearing over the course of 11 hours.

Pharmacotherapeutic group

Antihypertensives, antiadrenergic agents, centrally acting

Pharmacodynamic properties

Coated tablet; Film-coated tablet; Substance-powderPowder for oral suspension

Pharmacotherapeutic group: Antihypertensives, antiadrenergic agents, centrally acting

ATC code: C02AC05

In various animal models it has been shown that Моксонидин Канон has a strongly hypotensive effect. Available experimental data indicate that the site of action of Моксонидин Канон is located in the central nervous system (CNS).

In the brain stem, Моксонидин Канон binds selectively to I1-imidazoline receptors. These imidazoline-sensitive receptors are predominantly found in the rostral ventrolateral medulla, an area which plays an important role in central control of the sympathetic nervous system. The effect of this interaction with these I1-imidazoline receptors appears to be a reduction in the activity of the sympathetic nerves. This has been demonstrated for cardiac, splanchnic and renal sympathetic nerves.

Моксонидин Канон differs from other centrally acting antihypertensives in the fact that it has only a weak affinity for the central α2-adrenergic receptors compared to the affinity for I1-imidazoline receptors. Alpha2-adrenergic receptors are considered to be the intermediate pathway that causes sedation and dry mouth, the most commonly observed undesirable effects of centrally acting antihypertensives.

Mean systolic and diastolic blood pressure is reduced both at rest and during exercise. The effects of Моксонидин Канон on mortality and cardiovascular morbidity are currently unknown.

In humans, Моксонидин Канон leads to a reduction of systemic vascular resistance and consequently in arterial blood pressure.

Pharmacokinetic properties

Coated tablet; Film-coated tablet; Substance-powderPowder for oral suspension

Absorption

Моксонидин Канон is rapidly absorbed after oral administration. In humans, approximately 90% of an oral dose is absorbed. Ingestion of food has no effect on the pharmacokinetics of Моксонидин Канон. There is no first-pass metabolism and bioavailability is 88 %.

Distribution

Only about 7% of Моксонидин Канон is bound to human plasma proteins (Vdss = 1.8 ± 0.4 l/kg). Peak plasma levels of Моксонидин Канон are reached 30-180 minutes after administration of a film-coated tablet.

Biotransformation

Моксонидин Канон is 10-20% metabolised, predominantly to 4,5-dehydroМоксонидин Канон and to an aminomethanamidine derivative by opening of the imidazoline ring. The hypotensive effect of 4,5-dehydroМоксонидин Канон is only 1/10, and that of the aminomethanamidine derivative less than 1/100, of that of Моксонидин Канон.

Elimination

Моксонидин Канон and its metabolites are almost entirely eliminated via the kidney. More than 90% of the dose is eliminated in the first 24 hours via the kidney, while approximately 1% is eliminated in the faeces. The cumulative excretion of unchanged Моксонидин Канон is approximately 50-75%. The mean plasma elimination half-life is 2.2-2.3 hours and the renal half-life 2.6-2.8 hours.

Characteristics in patients with renal impairment

In patients with moderately impaired renal function (GFR 30 - 60 ml/min), the AUC increased by 85% and the clearance decreased by 52%. In such patients the hypotensive effect of Моксонидин Канон should be closely monitored, especially at the start of treatment. The dose must be adapted in these patients so that the maximum daily dose is not more than 0.4 mg and the maximum single dose is 0.2 mg.

In patients with severely impaired renal function (GFR < 30 ml/min) the clearance is reduced by 68 % and the elimination half live is prolonged up to 7 hours. In these patients Моксонидин Канон dosing should be initiated with 0.2 mg daily and can be increased to a maximum of 0.3 mg daily, if clinically indicated and well tolerated. In such patients the hypotensive effect of Моксонидин Канон should be closely monitored, especially at the start of treatment.

Special warnings and precautions for use

Coated tablet; Film-coated tablet; Substance-powderPowder for oral suspension

Cases of varying degrees of AV block have been reported in the post-marketing setting in patients undergoing Моксонидин Канон treatment. Based on these case reports, the causative role of Моксонидин Канон in delaying atrioventricular conduction cannot be completely ruled out. Therefore, caution is recommended when treating patients with a possible predisposition to developing an AV block.

When Моксонидин Канон is used in patients with 1st degree AV block special care should be exercised to avoid bradycardia. Моксонидин Канон must not be used in higher degree AV blocks.

When Моксонидин Канон is used in patients with severe coronary artery disease or unstable angina pectoris special care should be exercised due to the fact that there is limited experience in this patient population.

Due to lack of clinical evidence supporting safe use in patients with co-existing moderate cardiac insufficiency, Моксонидин Канон should be administered with caution in these patients.

Caution is advised in the administration of Моксонидин Канон to patients with renal impairment as Моксонидин Канон is excreted primarily via the kidneys. In these patients careful titration of the dose is recommended, especially at the start of therapy. Dosing should be initiated with 0.2 mg daily and can be increased to a maximum of 0.4 mg daily for patients with moderate renal impairment (GFR>30 ml/min but < 60 ml/min) and to a maximum of 0.3 mg daily for patients with severe renal impairment (GFR<30 ml/min) if clinically indicated and well tolerated.

If Моксонидин Канон is used in combination with a β-blocker, and both treatments have to be discontinued the β-blocker should be discontinued first, and, then Моксонидин Канон after a few days.

So far, no rebound effect on blood pressure has been observed after the discontinuation of treatment with Моксонидин Канон. However, it is advisable not to stop taking Моксонидин Канон abruptly, but to reduce it gradually over a period of two weeks.

The elderly population may be more susceptible to the CV effects of blood pressure lowering drugs. Therefore therapy should be started with the lowest dose and dose increments should be introduced with caution to prevent the serious consequences these reactions may lead to.

Моксонидин Канон contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed. However, somnolence and dizziness have been reported. This should be taken into account when performing these tasks.

Dosage (Posology) and method of administration

Coated tablet; Film-coated tablet; Substance-powderPowder for oral suspension

Posology

Adults

Treatment must be instituted with the lowest dosage of Моксонидин Канон. This means a daily dose of 0.2 mg Моксонидин Канон in the morning. If the therapeutic effect is insufficient, the dose can be increased after three weeks to 0.4 mg. This dose can be given as a single dose (to be taken in the morning) or as a divided daily dose (morning and evening). If the results are still insufficient after a further three weeks, the dosage can be increased further to a maximum of 0.6 mg given divided in the morning and evening. A single dose of 0.4 mg Моксонидин Канон and a daily dose of 0.6 mg Моксонидин Канон should not be exceeded.

Special populations

Elderly

Provided that renal function is not impaired, dosage recommendation is the same as for adults.

Paediatric population

Моксонидин Канон should not be given to children and adolescents under 18 years of age as insufficient safety and therapeutic data are available for this.
