Pharmacological properties

Pharmacodynamics

Combination drug, has antiviral, interferonogenic, antipyretic, analgesic, antihistamine and angioprotective action.

Paracetamol has analgesic and antipyretic effects.

Ascorbic acid is involved in the regulation of redox processes, contributes to normal capillary permeability, blood coagulation, tissue regeneration, plays a positive role in the development of immune reactions in the body, makes up for the lack of vitamin C.

Calcium gluconate as a source of calcium ions prevents development of increased permeability and fragility of blood vessels and causes hemorrhagic processes during influenza and acute respiratory viral infection (ARI) and has anti-allergic effect (mechanism is unknown).

Rimantadine has antiviral activity against influenza A virus. By blocking the M₂ channels of influenza A virus, it disrupts its ability to enter cells and release ribonucleoprotein, thereby inhibiting a crucial stage of viral replication. It induces production of interferon alpha and gamma. In influenza caused by B virus rimantadine has antitoxic effect.

Rutoside is an angioprotector. It reduces capillary permeability, swelling and inflammation, strengthens the vascular wall. Inhibits aggregation and increases the degree of deformation of red blood cells.

Loratadine is a blocker of H1-histamine receptors, prevents the development of tissue edema associated with the release of histamine.

Pharmacokinetics

Paracetamol. Absorption is high. Binding with plasma proteins – 15%. It penetrates through the blood-brain barrier. Metabolized in the liver in three main ways: conjugation with glucuronides, conjugation with sulfates, oxidation by liver microsomal enzymes. In the latter case toxic intermediate metabolites are formed, which subsequently conjugate with glutathione and then with cysteine and mercapturic acid. The main cytochrome P450 isoenzymes for this metabolic pathway are CYP2E1 (predominantly), CYP1A2 and CYP3A4 (secondary role). In glutathione deficiency, these metabolites can cause damage and necrosis of hepatocytes. Additional metabolic pathways are hydroxylation to 3-hydroxyparacetamol and methoxylation to 3-methoxy-paracetamol, which are subsequently conjugated to glucuronides or sulfates. In adults, glucuronidation predominates. Conjugated metabolites of paracetamol (glucuronides, sulfates and conjugates with glutathione) have low pharmacological (including toxic) activity. Excreted by the kidneys as metabolites, mainly conjugates, only 3% unchanged. In elderly patients, the drug clearance decreases and T_1/2 increases.

The maximum concentration (C_max) of paracetamol in plasma is reached after 0.7±0.39 hours when using the powder and is 4.79±1.81 µg/ml, the half-life (T_1/2) is 2.73±0.76 hours.

Ascorbic acid is absorbed in the gastrointestinal tract (mainly in the jejunum). The binding to plasma proteins is 25%. Diseases of the gastrointestinal tract (gastric and 12 duodenal ulcers, constipation or diarrhea, worm infestation, giardiasis), consumption of fresh fruit and vegetable juices, alkaline drinking reduce absorption of ascorbic acid in the intestine. Normal plasma concentration of ascorbic acid is approximately 10-20 µg/ml. Time of maximum plasma concentration after oral administration is 4 hours. It penetrates easily into leukocytes, platelets and then into all tissues; the highest concentration is reached in glandular organs, leukocytes, liver and eye lens; it penetrates through the placenta. The concentration of ascorbic acid in leukocytes and platelets is higher than in erythrocytes and plasma. In deficiency states the concentration in leukocytes decreases later and more slowly and is considered a better criterion for assessing deficiency than the concentration in plasma. It is metabolized mainly in the liver to deoxyascorbic acid and further to oxalic acetic acid and ascorbate-2-sulfate. It is excreted by the kidneys, through the intestines, with sweat unchanged and as metabolites. Smoking and use of ethanol accelerate the breakdown of ascorbic acid (conversion to inactive metabolites), dramatically reducing the body’s reserves. It is excreted by hemodialysis.

Calcium gluconate. Approximately 1/5-1/3 of orally administered calcium gluconate is absorbed in the small intestine; this process depends on the presence of ergocalciferol, pH, dietary characteristics, and the presence of factors that can bind calcium ions. Absorption of calcium ions increases with calcium deficiency and with a diet low in calcium ions. About 20% is excreted by the kidneys, the rest (80%) by the intestine.

Rimantadine. After oral administration it is almost completely absorbed in the intestine. Absorption is slow. Binding to plasma proteins is about 40%. Volume of distribution – 17-25 l/kg. Concentration in nasal secretion is 50% higher than in plasma. Metabolized in the liver. More than 90% is excreted by the kidneys within 72 hours, mainly as metabolites, 15% unchanged. In chronic renal failure the half-life is 2 times longer. In patients with renal insufficiency and in the elderly the drug may accumulate in toxic concentrations if the dose is not adjusted in proportion to the decrease in creatinine clearance. Hemodialysis has little effect on rimantadine clearance.

The C_max of rimantadine in plasma is reached with powder administration after 5.28±2.54 hours and is 69.0±19.7 ng/mL, T_1/2 is 33.26±12.76 hours.

Rutoside. Time of maximum concentration in blood plasma after oral administration – 1-9 hours. It is excreted mainly with the bile and to a lesser extent by the kidneys. T_1/2 is 10-25 h.

Loratadine. Rapidly and completely absorbed in the gastrointestinal tract. The maximum concentration in the elderly is increased by 50%. Binding with plasma proteins is 97%. It is metabolized in the liver with the formation of the active metabolite descarboethoxyloratadine with the participation of cytochrome isoenzymes CYP3A4 and to a lesser extent CYP2D6. It does not penetrate the blood-brain barrier. It is excreted by the kidneys and in bile. Pharmacokinetics is practically unchanged in patients with chronic renal insufficiency and in hemodialysis.

The C_max of loratadine in plasma is reached after 3.28±1.25 hours and is 1.85±0.95 ng/mL, T_1/2 is 11.29±5.52 hours.

How to take, the dosage

Internal.

Dissolve the contents of one sachet in half a cup (100 ml) of boiled warm water. Drink as soon as it dissolves. Stir the solution before drinking.

Adults: take 1 sachet 2-3 times a day after meals. The interval between doses of the drug is 4-6 hours. The course of therapy 3-5 days until the disappearance of the symptoms. Anvimax® must not be taken more than 5 days.

If there is no relief of symptoms within 3 days of starting the drug, a doctor should be consulted.

Interaction

Paracetamol reduces the effectiveness of uricosuric drugs. Concomitant use of paracetamol in high doses increases the effect of anticoagulant drugs. Inducers of microsomal oxidation in the liver (phenytoin, barbiturates, rifampicin, phenylbutazone, tricyclic antidepressants), ethanol and hepatotoxic drugs increase production of hydroxylated active metabolites, which causes the possibility of severe intoxication even with a small overdose. Simultaneous use with metoclopramide may increase the rate of absorption of paracetamol. Prolonged use of barbiturates reduces the effectiveness of paracetamol. Microsomal oxidation inhibitors reduce the risk of hepatotoxic effects.

Rimantadine increases the excitatory effect of caffeine. Cimetidine reduces the clearance of rimantadine by 18%.

Ascorbic acid increases the blood concentration of benzylpenicillin. Improves intestinal absorption of iron preparations (converts trivalent iron to divalent iron); may increase iron excretion when used concomitantly with deferoxamine. Increases the risk of crystalluria when treated with salicylates and short-acting sulfonamides, slows renal excretion of acids, increases excretion of drugs with an alkaline reaction (including alkaloids). Reduces the blood concentration of oral contraceptives. Increases the total clearance of ethanol, which in turn reduces the concentration of ascorbic acid in the body. When used concomitantly, reduces the chronotropic effect of isoprenaline. Barbiturates and primidone increase excretion of ascorbic acid with urine. Reduces the therapeutic effect of antipsychotic drugs (neuroleptics) – phenothiazine derivatives, tubal reabsorption of amphetamine and tricyclic antidepressants.

Loratadine. CYP3A4 and CYP2D6 inhibitors increase the blood concentration of loratadine.

Special Instructions
