Moxonidine-LF

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 binding to plasma proteins is 7.2%.

Metabolism

The main metabolite is dehydrogenated moxonidine. The pharmacodynamic activity of dehydrogenated moxonidine is about 10% compared to moxonidine.

Removal

The half-life (T1/2) of moxonidine and 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 dehydriromoxonidine, other metabolites in the urine do not exceed 8% of the dose taken). Less than 1% of the dose is excreted through the intestines.

Pharmacokinetics in patients with arterial hypertension

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

Pharmacokinetics in old age

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.

Pharmacokinetics in children

Moxonidine is not recommended for use in persons under 18 years of age, and therefore no pharmacokinetic studies have been conducted in this group.

Pharmacokinetics in renal 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 individuals 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 renal impairment, the dosage should be adjusted individually. Moxonidine is excreted to a small extent during hemodialysis.

T1/2 of moxonidine and 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 dihydromoxonidine, other metabolites in the urine do not exceed 8% of the dose taken). Less than 1% of the dose is excreted through the intestines.

Pharmacokinetics in special clinical situations

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

Moxonidine is not recommended for use in persons under 18 years of age because No pharmacokinetic studies were conducted in this group.

Moxonidine excretion is significantly correlated with CC. In patients with moderate renal failure (creatinine clearance in the range of 30-60 ml/min), plasma Css and final T1/2 are approximately 2 and 1.5 times higher than in individuals with normal renal function (creatinine clearance more than 90 ml/min) . In patients with severe renal failure (creatinine clearance less than 30 ml/min), plasma Css 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 to severe renal failure. In patients with end-stage renal failure (creatinine clearance less than 10 ml/min) on hemodialysis, plasma Css and final T1/2 are 6 and 4 times higher, respectively, than in patients with normal renal function. In all groups, the Cmax of moxonidine in blood plasma is 1.5-2 times higher. Moxonidine is excreted to a small extent during hemodialysis.

special instructions

If it is necessary to cancel concomitantly taken beta-blockers and moxonidine, first cancel the beta-blockers and only after a few days moxonidine. It is not recommended to prescribe tricyclic antidepressants simultaneously with moxonidine. During treatment, regular monitoring of blood pressure, heart rate and ECG is necessary. Moxonidine should be stopped gradually.

Indications for use

Arterial hypertension.

Directions for use and doses

Inside, regardless of food intake, with a sufficient amount of liquid. In most cases, the initial dose of moxonidine is 0.2 mg per day in one dose, preferably in the morning. If the therapeutic effect is insufficient, the dose can be increased after 3 weeks of therapy to 0.4 mg per day in 2 doses or once. The maximum single dose is 0.4 mg. The maximum daily dose, which should be divided into 2 doses, is 0.6 mg. Abrupt discontinuation of moxonidine is not recommended. Moxonidine should be discontinued gradually over 2 weeks. In patients with moderate renal failure (GFR more than 30 ml/min, but less than 60 ml/min), a single dose of moxonidine 0.2 mg and a daily dose of moxonidine 0.4 mg should not be exceeded. In patients on hemodialysis, the initial dose is 0.2 mg per day. If necessary and if well tolerated, the dose can be increased to 0.4 mg per day. Studies on the use of moxonidine in patients with liver failure have not been conducted. In elderly patients with normal renal function, dosage recommendations are the same as for adult patients.

Use during pregnancy and lactation

There are no clinical data on the treatment of pregnant women with moxonidine. Animal studies have revealed embryotoxic effects. As a precaution, taking moxonidine during pregnancy is not recommended. Moxonidine passes into breast milk. Breastfeeding women are advised to stop breastfeeding or discontinue the drug during treatment.

Impact on the ability to drive vehicles and operate machinery

During the treatment period, it is necessary to refrain from driving vehicles and engaging in potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

Carefully

Parkinson's disease (severe), epilepsy, glaucoma, depression, intermittent claudication, Raynaud's disease, first degree atrioventricular block, chronic renal failure (creatinine clearance more than 30 but less than 60), cerebrovascular diseases, after myocardial infarction, chronic heart disease insufficiency class I and II (according to the NYHA classification), for patients on hemodialysis; due to lack of experience in use - moderate liver failure (more than 9 points according to the Child-Pugh classification).

Interaction with other drugs

Concomitant use of other antihypertensive drugs enhances the hypotensive effect of moxonidine. Since tricyclic antidepressants may reduce the effect of centrally acting antihypertensive drugs, coadministration of tricyclic antidepressants with moxonidine is not recommended. Moxonidine may enhance the effect of tricyclic antidepressants (simultaneous use should be avoided), tranquilizers, alcohol, sedatives and hypnotics. Moxonidine may moderately improve impaired cognitive function in patients receiving lorazepam. Prescribing moxonidine together with benzodiazepines may be accompanied by an increase in the sedative effect of the latter. Moxonidine is eliminated by tubular secretion. Interactions with other drugs eliminated by tubular secretion cannot be excluded. When taken orally simultaneously with glibenclamide, the bioavailability of glibenclamide is reduced by 11%.

Contraindications

Hypersensitivity to the components of the drug; sick sinus syndrome, sinoatrial and atrioventricular block II and III degrees, severe bradycardia (resting heart rate (HR) less than 50 beats/min), chronic heart failure class III and IV (NYHA classification), history of angioedema, severe liver failure, unstable angina, chronic renal failure (creatinine clearance less than 30 ml/min, creatinine more than 160 µmol/l), age under 18 years (efficacy and safety have not been established), lactation, pregnancy, concomitant use with tricyclic antidepressants. Hereditary galactose intolerance, lactase deficiency or glucose-galactose malabsorption.
