Moxarel

Moxarel®

Suction

After oral administration, moxonidine is rapidly and almost completely absorbed from the upper gastrointestinal tract. Absolute bioavailability is approximately 88%, indicating no significant first-pass effect. The time to reach maximum concentration is about 1 hour. Food intake does not affect the pharmacokinetics of the drug.

Distribution

The connection with blood plasma proteins is 7.2%.

Metabolism

The main metabolite is a dehydrogenated derivative of moxonidine. The pharmacodynamic activity of the main metabolite is about 10% of the activity of moxonidine.

Removal

The half-life (T1/2) of moxonidine and the dehydrogenated metabolite is 2.5 and 5 hours, respectively. Within 24 hours, over 90% of moxonidine is excreted by the kidneys (about 78% unchanged and 13% as dehydromoxonidine, the level of other metabolites in the urine does not exceed 8% of the dose taken). Less than 1% of the dose is excreted through the intestines.

Pharmacokinetics in special groups of patients

Patients with arterial hypertension

Compared with healthy volunteers, patients with arterial hypertension show no changes in the pharmacokinetics of moxonidine.

Elderly patients

Clinically insignificant changes in the pharmacokinetic parameters of moxonidine were noted in elderly patients, probably due to a decrease in the intensity of its metabolism and/or slightly higher bioavailability.

Children

Moxonidine is contraindicated for use in patients under 18 years of age, and therefore pharmacokinetic studies have not been conducted in this group.

Patients with kidney failure

Moxonidine excretion is significantly correlated with creatinine clearance (CC). In patients with moderate renal failure (creatinine clearance in the range of 30-60 ml/min), steady-state plasma concentrations and final T1/2 are approximately 2 and 1.5 times higher than in patients with normal renal function (creatinine clearance more than 90 ml/min). min).

In patients with severe renal failure (creatinine clearance less than 30 ml/min), steady-state plasma concentrations and final T1/2 are 3 times higher than in patients with normal renal function. The administration of multiple doses of moxonidine leads to predictable accumulation in the body of patients with moderate and severe renal failure. In patients with end-stage renal failure (creatinine clearance less than 10 ml/min) on hemodialysis, steady-state plasma concentrations and final T1/2 are 6 and 4 times higher, respectively, than in patients with normal renal function. In patients with moderate renal failure, the maximum concentration of moxonidine in the blood plasma is 1.5-2 times higher. In patients with impaired renal function, the dosage should be adjusted individually.

Moxonidine is excreted to a small extent during hemodialysis.

Moxarel 0.2 mg 30 pcs. film-coated tablets

pharmachologic effect

Moxonidine is an antihypertensive agent with a central mechanism of action.
In the brain stem structures (rostral layer of the lateral ventricles), moxonidine selectively stimulates imidazoline-sensitive receptors that take part in the tonic and reflex regulation of the sympathetic nervous system. Stimulation of imidazoline receptors reduces peripheral sympathetic activity and blood pressure. Moxonidine differs from other sympatholytic antihypertensive drugs in its lower affinity for α2-adrenergic receptors, which explains the lower likelihood of developing sedation and dryness of the oral mucosa.

Taking moxonidine leads to a decrease in systemic vascular resistance and blood pressure.

Moxonidine improves the insulin sensitivity index in patients with obesity, insulin resistance and moderate arterial hypertension.

Application of Moxarel 0.2 mg 30 pcs. film-coated tablets during pregnancy and breastfeeding

There are no clinical data on the treatment of pregnant women with Moxarel.

Moxarel should be prescribed with caution during pregnancy only after a careful assessment of the risk-benefit ratio, when the benefit to the mother outweighs the potential risk to the fetus.

Moxonidine passes into breast milk. Breastfeeding women are advised to stop breastfeeding or discontinue the drug during treatment.

Contraindicated in patients under 18 years of age, since the effectiveness and safety of moxonidine have not been established.

special instructions

There is currently no evidence that stopping Moxarel leads to an increase in blood pressure. However, it is not recommended to stop taking Moxarel suddenly; instead, you should gradually reduce the dose of the drug over two weeks.

If it is necessary to cancel concomitantly taken beta-blockers and the drug Moxarel, first cancel the beta-blockers, and only after a few days moxonidine.

During treatment, regular monitoring of blood pressure, heart rate and ECG registration is necessary. You should stop taking Moxarel gradually.

During treatment with Moxarel, alcohol consumption should be avoided.

Impact on the ability to drive vehicles and operate machinery:

The effect of Moxarel on the ability to drive vehicles or operate machinery has not been studied. However, given the possible occurrence of dizziness and drowsiness, patients should be careful when engaging in potentially hazardous activities that require increased attention, such as driving a vehicle or operating equipment that requires increased concentration.

Overdose

Symptoms: headache, sedation, drowsiness, marked decrease in blood pressure, dizziness, increased fatigue, asthenia, bradycardia, dry oral mucosa, vomiting and pain in the epigastric region, respiratory depression, impaired consciousness. A short-term increase in blood pressure, tachycardia, and hyperglycemia are also potentially possible.

Treatment: There is no specific antidote. In case of a pronounced decrease in blood pressure, it is recommended to administer fluid to restore blood volume and dopamine. Bradycardia can be relieved with atropine. α-Adrenergic antagonists may reduce or eliminate the paradoxical hypertensive effects of moxonidine overdose. In severe cases of overdose, it is recommended to carefully monitor disturbances of consciousness and avoid respiratory depression. Moxonidine is excreted to a small extent during hemodialysis.

Drug interactions

The combined use of moxonidine with other antihypertensive drugs leads to an additive effect.

Tricyclic antidepressants may reduce the effectiveness of centrally acting antihypertensive drugs, and therefore their use together with moxonidine is not recommended.

Moxonidine may enhance the effect of tricyclic antidepressants, tranquilizers, ethanol, sedatives and hypnotics.

Moxonidine may moderately improve impaired cognitive function in patients receiving lorazepam.

Prescribing moxonidine together with benzodiazepine derivatives may be accompanied by an increase in the sedative effect of the latter.

The simultaneous use of moxonidine with beta-blockers leads to increased bradycardia, the severity of ino- and dromotropic effects.

When moxonidine is prescribed together with moclobemide, there is no pharmacodynamic interaction.

Moxonidine is released by tubular secretion, so its interaction with other drugs released by tubular secretion is possible.
