Pharmacology
The combination type drug has the following effects:
- antipyretic;
- antihistamine;
- antiviral;
- painkiller.
The medicine is a combination medicine, since it contains several active elements. Therefore, the use of Anvimax refers to complex treatment.
Ascorbic acid has a positive effect on the immune system and triggers natural tissue regeneration processes.
The action of the substance rimantadine is aimed only at the influenza virus type A. It prevents the penetration of harmful microorganisms into the body.
Calcium gluconate is an ion donor. They seep into the vascular walls, which prevents the appearance of increased fragility and permeability of capillaries. This allows you to overcome the source of the inflammatory process during viral diseases and influenza.
Loratadine prevents swelling of virus-infected tissues.
The action of rutoside is aimed at maintaining the integrity of the walls of blood vessels. The active substance makes capillaries less fragile and permeable. It also prevents the appearance of swelling and inflammatory reactions in the affected area.
Paracetamol is well absorbed from the stomach. The maximum concentration is reached 20-30 minutes after administration.
AnviMax, powder for oral solution, lemon, 5 g, 12 pcs.
Paracetamol. Absorption is high. Communication with plasma proteins - 15%. Penetrates the blood-brain barrier. Metabolized in the liver in three main ways: conjugation with glucuronides, conjugation with sulfates, oxidation by microsomal liver enzymes. In the latter case, toxic intermediate metabolites are formed, which are subsequently conjugated with glutathione, and then with cysteine and mercapturic acid. The main isoenzymes of cytochrome P450 for this metabolic pathway are the isoenzyme CYP2E1 (mainly), CYP1A2 and CYP3A4 (minor role). With glutathione deficiency, these metabolites can cause damage and necrosis of hepatocytes. Additional metabolic pathways include 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 in the form of metabolites, mainly conjugates, only 3% unchanged. In elderly patients, drug clearance decreases and T1/2 increases.
The maximum concentration (Cmax) of paracetamol in the blood plasma is achieved when using the powder after 0.7±0.39 hours and is 4.79±1.81 mcg/ml, the half-life (T1/2) is 2.73±0.76 h.
Ascorbic acid is absorbed in the gastrointestinal tract (mainly in the jejunum). Communication with plasma proteins - 25%. Diseases of the gastrointestinal tract (peptic ulcer of the stomach and duodenum, constipation or diarrhea, helminthic infestation, giardiasis), consumption of fresh fruit and vegetable juices, alkaline drinking reduce the absorption of ascorbic acid in the intestines. The normal concentration of ascorbic acid in plasma is approximately 10-20 μg/ml. The time of maximum concentration in blood plasma after oral administration is 4 hours. Easily penetrates into leukocytes, platelets, and then into all tissues; the highest concentration is achieved in the glandular organs, leukocytes, liver and lens of the eye; penetrates the placenta. The concentration of ascorbic acid in leukocytes and platelets is higher than in erythrocytes and plasma. In deficiency states, leukocyte concentrations decline later and more slowly and are considered a better measure of deficiency than plasma concentrations. Metabolized primarily in the liver into deoxyascorbic acid and further into oxaloacetic acid and ascorbate-2-sulfate. It is excreted by the kidneys, through the intestines, with sweat, unchanged and in the form of metabolites. Smoking and drinking ethanol accelerate the destruction of ascorbic acid (conversion into inactive metabolites), sharply reducing reserves in the body. Excreted during 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, diet and the presence of factors capable of binding calcium ions. The absorption of calcium ions increases with calcium deficiency and the use of a diet with a reduced content of calcium ions. About 20% is excreted by the kidneys, the rest (80%) by the intestines.
Rimantadine. After oral administration, it is almost completely absorbed from the intestines. Absorption is slow. Communication with plasma proteins is about 40%. Volume of distribution - 17-25 l/kg. The concentration in nasal secretions is 50% higher than the plasma concentration. Metabolized in the liver. More than 90% is excreted by the kidneys within 72 hours, mainly in the form of metabolites, 15% unchanged. In chronic renal failure, the half-life increases by 2 times. May accumulate in toxic concentrations in persons with renal impairment and in the elderly unless the dose is adjusted proportionately to the decrease in creatinine clearance. Hemodialysis has little effect on the clearance of rimantadine.
Cmax of rimantadine in blood plasma is achieved when using the powder after 5.28±2.54 hours and is 69.0±19.7 ng/ml, T1/2 - 33.26±12.76 hours.
Rutoside. The time of maximum concentration in blood plasma after oral administration is 1-9 hours. It is excreted mainly with bile and to a lesser extent by the kidneys. T1/2 - 10-25 hours.
Loratadine. Quickly and completely absorbed from the gastrointestinal tract. The maximum concentration in older people increases by 50%. Bonding with plasma proteins is 97%. Metabolized in the liver to form the active metabolite descarboethoxyloratadine with the participation of cytochrome isoenzymes CYP3A4 and, to a lesser extent, CYP2D6. Does not penetrate the blood-brain barrier. Excreted by the kidneys and bile. In patients with chronic renal failure and during hemodialysis, the pharmacokinetics remain virtually unchanged.
Cmax of loratadine in blood plasma is achieved after 3.28±1.25 hours and is 1.85±0.95 ng/ml, T1/2 is 11.29±5.52 hours.
