PHARMACHOLOGIC EFFECT

Antihypertensive drug, diuretic.

Indapamide belongs to the group of non-azide sulfonamides, by pharmacological properties it is close to thiazide-like diuretics.
Reduces the tone of smooth arteries musculature, reduces OPSS. The drug has a moderate saluretic and diuretic effects, which are associated with the blockade of the reabsorption of sodium, chlorine, hydrogen ions and, to a lesser extent, potassium ions in the proximal tubules and the cortical segment of the distal tubules of the kidneys. Possessing the ability to selectively block the "slow" calcium channels, increases the elasticity of the walls of the arteries and reduces the OPSS. Helps reduce hypertrophy of the left ventricle of the heart. Does not affect the content of lipids in the plasma (triglycerides, LDL, HDL); does not affect carbohydrate metabolism (including in patients with concomitant diabetes mellitus). The decrease in OPSS is also due to a decrease in the sensitivity of adrenoreceptors of the vascular wall to noradrenaline and angiotensin II, an increase in the synthesis of prostaglandins with vasodilating activity (prostaglandin PgE2 and prostacyclin PgI2). Reduces the production of free and stable oxygen radicals. At appointment in high doses does not influence a degree of depression of a BP, despite of an increase in a diuresis.
The antihypertensive effect is manifested by the end of the first week, remains for 24 hours against the background of a single dose, reaches a maximum 8-12 weeks after the start of the drug.

PHARMACOKINETICS

Suction

After ingestion, indapamide is rapidly and completely absorbed from the digestive tract, bioavailability is high (93%).
Eating somewhat slows the rate of absorption, but does not affect the completeness of absorption. After taking the drug inside at a dose of 2.5 mg C max in the blood is achieved after 1-2 hours.
Distribution

Binding to plasma proteins is about 75%.
It also binds to the elastin of the smooth muscles of the vascular wall. Has a high V d , passes through the histohematological barriers (including placental), penetrates into breast milk.
Metabolism and excretion

Metabolised in the liver.
T 1/2 is an average of 14-18 hours. It is mainly excreted through the kidneys - 60-80% (in most cases - in the form of metabolites, about 5% - unchanged), through the intestine - 20-23%.
In patients with renal insufficiency, pharmacokinetics does not change.
Do not cumulate.
INDICATIONS

- arterial hypertension.

DOSING MODE

The drug is administered orally, in the morning, regardless of food intake.
Capsule should be swallowed without chewing, washed down with water.
Assign 2.5 mg (1 caps.) 1 time / day.

The drug can be used as a monotherapy or in combination with other antihypertensive agents (with beta-adrenoblockers, slow calcium channel blockers, ACE inhibitors).
If after 4-8 weeks of treatment the desired therapeutic effect is not achieved, the dose of the drug should not be increased (the risk of side effects increases without increasing the antihypertensive effect). Instead, another antihypertensive drug that is not a diuretic should be added to the treatment regimen. In cases where treatment should begin with the reception of 2 preparations, the dose of Indap remains 2.5 mg in the morning 1 time / day.

SPECIAL INSTRUCTIONS

Indapamide is effective for the treatment of patients with arterial hypertension at risk, i.e.
with concomitant pathology (diabetes mild to moderate severity or with chronic renal failure, patients with hyperlipidemia).
With prolonged use of indapamide, electrolyte disturbances can sometimes occur, such as hyponatremia, hypokalemia, hypercalcemia, and hypochloraemic alkalosis.These disorders are more often observed in patients with chronic heart failure, liver diseases, with vomiting and diarrhea, as well as in individuals on a salt-free diet, which necessitates the control of blood electrolytes.

Indapamide increases the release of magnesium in the urine, which can lead to hypomagnesemia.

When using indapamide, the uric acid and residual nitrogen content in the blood plasma should also be systematically monitored.

Perhaps the appearance of orthostatic hypotension, which can be provoked by alcohol intake, barbiturates, opioid analgesics, and also by other antihypertensive drugs.

In the case of hypokalemia caused by indapamide, the toxicity of cardiac glycosides may increase.
In patients taking cardiac glycosides, laxatives, with hyperaldosteronism, as well as in the elderly, careful monitoring of the potassium and creatinine content is shown.
The most thorough control is indicated in patients with cirrhosis of the liver (especially with edema or ascites - the risk of metabolic alkalosis, increasing manifestations of hepatic encephalopathy), IHD, chronic heart failure, and also in the elderly.
Patients with an increased QT interval on the ECG (congenital or developing against a background of a pathological process) also belong to the high-risk group.
The first measurement of the potassium concentration in the blood should be performed within 1 week of treatment.

Hypercalcemia on the background of taking indapamide may be a consequence of previously undiagnosed hyperparathyroidism.

In patients with diabetes, it is extremely important to monitor blood glucose levels, especially when hypokalemia is present.

Significant dehydration can lead to the development of acute renal failure (reduced glomerular filtration).
Patients must compensate for the loss of water and at the beginning of treatment carefully monitor the kidney function.
Indapamide can give a positive result in the conduct of doping control.

Patients with hypertension and hyponatremia (due to taking diuretics) need to stop taking diuretics 3 days before the start of taking ACE inhibitors (if necessary, diuretics can be taken a little later) or they are given initial low doses of ACE inhibitors.

Indapamide may worsen the course of systemic lupus erythematosus.

Despite the fact that indapamide has virtually no effect on carbohydrate metabolism, in patients with insulin-dependent diabetes mellitus it is possible to increase the necessary dose of insulin, and for latent diabetes it is necessary to monitor blood glucose.

OVERDOSE

Symptoms: nausea, vomiting, weakness, dysfunction of the gastrointestinal tract, water-electrolyte disorders, in some cases - excessive decrease in blood pressure, respiratory depression.
In patients with cirrhosis, the development of hepatic coma is possible.
Treatment: gastric lavage, correction of water-electrolyte balance, symptomatic therapy.
There is no specific antidote.
DRUG INTERACTION

It is not recommended to use indapamide and lithium drugs simultaneously because of the possibility of developing a toxic effect of lithium against the background of a decrease in its renal clearance.

The combined use of indapamide with astemizole, erythromycin (IV), pentamidine, sultopride, terfenadine, vincamine, antiarrhythmic drugs IA (quinidine, disopyramide) and grade III (amiodarone, brethylium, sotalol) may reduce the hypotensive effect of indapamide and lead to arrhythmia in type "pirouette" due to the synergistic effect (lengthening) on ​​the duration of the QT interval.

NSAIDs, GCS, tetracosactide, adrenostimulants reduce the hypotensive effect, baclofen strengthens.

Saluretics (loop, thiazide), cardiac glycosides, gluco- and mineralocorticosteroids, tetracosactide, laxatives, amphotericin B (IV) increase the risk of hypokalemia.

With simultaneous admission with cardiac glycosides, the likelihood of developing digitalis intoxication increases;
with calcium preparations - hypercalcemia; with metformin, aggravation of lactic acidosis is possible.
Combination with potassium-sparing diuretics can be effective in some patients, but the possibility of hypo- or hyperkalemia, especially in patients with diabetes mellitus and renal insufficiency, is not completely excluded.

ACE inhibitors increase the risk of arterial hypotension and / or acute renal failure (especially with existing renal artery stenosis).

Indapamide increases the risk of developing kidney failure when using iodine-containing contrast agents in high doses with dehydration of the body.
Before using iodine-containing contrast agents, patients need to restore fluid loss.
Tricyclic antidepressants and antipsychotics can increase the antihypertensive effect of the drug and increase the risk of orthostatic hypotension.

With simultaneous use with cyclosporine, an increase in the level of creatinine in the blood plasma is possible.

Reduces the effect of indirect anticoagulants (coumarin or indanedione derivatives) due to an increase in the concentration of coagulation factors as a result of a decrease in BCC and increase in their production by the liver (dose adjustment may be required).

Strengthens the blockade of the neuromuscular transmission, which develops under the action of nondepolarizing muscle relaxants.
