Amoxicillin 500mg: Pharmacology

Mode of action - antibacterial broad-spectrum bactericidal.

Inhibits transpeptidase, violates the synthesis of peptidoglycan (the reference protein of the cell wall) during the division and growth, causes lysis of microorganisms.

It has a wide spectrum of antimicrobial action. It is active against aerobic Gram-positive microorganisms - Staphylococcus spp. (Except for strains producing penicillinase), Streptococcus spp., Including Streptococcus faecalis, Streptococcus pneumoniae, aerobic gram-negative organisms - Neisseria gonorrhoeae, Neisseria meningitidis, Escherichia coli, Proteus mirabilis, Haemophilus influenzae, some strains of Salmonella, Shigella, Klebsiella, and Helicobacter pylori.

It operates on indolpolozhitelnye strains of Proteus (P.vulgaris, P.rettgeri); Serratia spp., Enterobacter spp., Morganella morganii, Pseudomonas spp. By its action resistant rickettsiae, mycoplasmas, viruses.

When administered as a suspension in doses of 125 mg / 5 mL and 250 mg / 5 ml fast and good (75-90%) is absorbed, creating Cmax (1,5-3,0 g / mL and 3.5-5, 0 .mu.g / ml, respectively) after 1-2 hours. When administered in capsules at doses of 250 and 500 mg Cmax (3,5-5,0 mg / ml and 5.5-7.5 mg / ml, respectively) also achieved in 1-2 hours. Stable under acidic conditions, it does not affect food intake on absorption.

When parenteral administration is rapidly absorbed and distributed in the tissues and body fluids; Cmax in the blood is detected 1 h after the / m and stored at therapeutic levels following parenteral administration for 6-8 hours.

Binding to plasma proteins is approximately 20%. Easily passes gistogematicalkie barriers, in addition to the unchanged BBB and penetrate quickly into most tissues and body fluids; accumulate at therapeutic concentrations in the peritoneal fluid, urine, content of skin blisters, pleural effusion, lung tissue, intestinal mucosa, female genital mutilation, the fluid of the middle ear, gall bladder and bile (with normal liver function), fetal tissues (it passes through the placental barrier ). T1 / 2 is 1-1.5 hours. In case of violation of renal function T1 / 2 extended to 4-12,6 hours, depending on the creatinine clearance. Partially metabolized to form inactive metabolites. 50-70% excreted by the kidneys unchanged by tubular secretion (80%) and glomerular filtration rate (20%), 10-20% - the liver. Trace amounts determined in the serum after 8 hours after ingestion. The small amount is excreted in breast milk.

Overdose

Symptoms include nausea, vomiting, diarrhea, disruption of water and electrolyte balance (a consequence of vomiting and diarrhea); long-term use at high doses - neurotoxic reactions and thrombocytopenia (these phenomena are reversible and disappear after discontinuation of the drug).

Treatment: gastric lavage, the appointment of activated carbon, saline laxatives, correction fluid and electrolyte balance; hemodialysis.

Inside, in / m, / jet and drip. Before the appointment should be selected to determine the sensitivity of the pathogen. The dosage regimen is determined individually depending on the severity of the infection. Adults and children over 10 years (weighing over 40 kg) - inside, 500 mg 3 times a day (up to 0.75-1 g 3 times a day in severe infections); maximum daily dose - 6 g administered to children in the form of a suspension, the dose depends on the age, body weight and severity of the infection.

In acute uncomplicated gonorrhea - 3 g once (for women re-introduction is recommended).

Patients with Cl creatinine below 10 ml / min, the dose is reduced by 15-50%, with anuria dose should not exceed 2 grams per day. The average exchange rate - 5-7 days (with streptococcal infections - not less than 10 days).

The / m, / jet and drip. When a single dose of greater than 2 g of the drug is introduced into / in the drip. The daily dose distribute 2-3 administration.

Single dose for children with the / m introduction - not more than 0,5 g In severe infections the dose for adults and children can be increased 1.5-2 times, in this case, the drug is introduced into / in. The daily dose distribute administration intervals of 2-3 hours 8-12.

In renal insufficiency, the treatment regimen is adjusted by reducing the dose or extending the interval between injections (24-48 h). When creatinine Cl 10-30 ml / min, the drug administered in a daily dose of 1 g, and then - by 0.5 g every 12 h; . If Cl creatinine less than 10 mL / min - 1 g, followed by 0.5 g every 24 hours in patients in a state of anuria daily dose should not exceed 2 in patients on hemodialysis, appoint an additional 2 g of the drug: 0.5 g during hemodialysis and 0.5 g after its completion.
