the Pharmacological

Pharmacokinetics Absorption properties – high, kislotoustoychiv, is lipophilic. The bioavailability after single dose of 500 mg – 37% (effect of ‘the first passing’ through a liver), the maximum concentration (Cmax) after oral administration of 500 mg – 0.4 mg/l, time of achievement of the maximum concentration (TCmax) – 2.5-2.9 h, in fabrics and cells concentration is 10-50 times higher, than in blood serum, distribution volume – 31.1 l/kg. Easily passes gistogematichesky barriers. Well gets into airways, urinogenital bodies and fabrics, into a prostate, into skin and soft tissues, collects in the environment with low pH, in lysosomes (that is especially important for an eradikation of intracellularly located activators). It is transported also by phagocytes, polymorphonuclear leukocytes and macrophages. Gets through cell membranes and creates high concentrations in them.
Concentration in the centers of an infection it is reliable above (for 24-34%), than in healthy fabrics, and correlates with severity of inflammatory hypostasis. In the center of inflammation remains in effective concentration within 5-7 days after reception of the last dose. Communication with proteins of plasma – 7-50% (it is inversely proportional concentration in blood).
In a liver it demetilirutsya, the formed metabolites are not active. Isoenzymes of CYP3A4, CYP3A5, CYP3A7 which inhibitor it is participate in metabolism of drug. Plasma clearance – 630 ml/min.: elimination half-life (T1/2) between 8 and 24 h after reception makes 14-20 h, T1/2 in the range from 24 up to 72 h – is removed with bile in not changed look, 6% 41 h 50% – kidneys.
Meal significantly changes pharmacokinetics: Cmax decreases by 52%, the area under a pharmacokinetic curve concentration time (AUC) – for 43%.
At elderly men (65-85 years) the pharmacokinetic parameters do not change, at women Cmax increases (by 30-50%).
A pharmacodynamics
Azithromycin – a bacteriostatic antibiotic of a broad spectrum of activity from group of macroleads azaleads. Possesses a wide range of antimicrobic action. The mechanism of effect of azithromycin is connected with suppression of synthesis of protein of a microbic cell. Contacting a ribosome 50S-subunit, oppresses to a peptidtranslokaz at a stage of broadcasting and suppresses protein synthesis, slowing down growth and reproduction of bacteria. In high concentrations has bactericidal effect.
Has activity concerning a row gram-positive, gram-negative, anaerobe bacterias, intracellular and other microorganisms.
Microorganisms can initially be resistant to action of an antibiotic or can gain resistance to it.

– a heavy liver failure (class B above on a scale of Chayld-Pyyu)
– the lactation period
– a concomitant use with ergotamine and dihydroergotamine
– children’s and teenage age up to 18 years

Medicinal interactions
Antacids (aluminum and magniysoderzhashchy) do not affect bioavailability, but reduce concentration of azithromycin in blood by 30% therefore the interval between their reception has to make 1 hour to or 2 hours after intake of the specified drugs.
At simultaneous use with derivatives of ergotamine and dihydroergotamine strengthening of toxic action (vasospasm, a dizesteziya) of the last is possible.
At combined use with anticoagulants of indirect action of a coumarinic row (warfarin) and azithromycin (in usual doses) careful control of a prothrombin time is necessary for patients.
It is necessary to be careful at combined use of a terfenadin and azithromycin as it was established that the concomitant use of a terfenadin and macroleads causes arrhythmia and lengthening of Q-T of an interval. Proceeding from it, it is impossible to exclude the above-stated complications at joint reception of a terfenadin and azithromycin.
At simultaneous use with cyclosporine it is necessary to control concentration of cyclosporine in blood.
At simultaneous use with digoxin the control of concentration of digoxin in blood is necessary (possibly increase in absorption of digoxin in intestines).
At simultaneous use with nelfinaviry increase in frequency of side reactions of azithromycin (decrease in hearing, increase in activity of hepatic transaminases) is possible.
At simultaneous use with a zidovudine azithromycin does not influence pharmacokinetic parameters of a zidovudine in blood plasma or on removal by kidneys of its and its metabolite of a glucuronide, but concentration of an active metabolite of a fosforilirovanny zidovudine in mononuclear cells of peripheral vessels increases. The clinical value of this fact is not defined.
It is necessary to consider a possibility of inhibition of an isoenzyme of CYP3A4 of azithromycin at simultaneous use with cyclosporine, terfenadiny, ergot alkaloids, tsizapridy, Pimozidum, quinidine, astemizoly and other medicines which metabolism happens to participation of this enzyme.
Azithromycin does not affect concentration of carbamazepine, Cimetidinum, a didanozin, efavirenz, flukonazol, indinavir, midazolam, theophylline, a triazolam, Trimethoprimum/sulfamethoxazole, a tsetirizin, sildenafil, atorvastatin, rifabutin and Methylprednisolonum in blood at simultaneous use.

Special instructions
With care arrhythmia, including predisposition ment of arrhythmia and lengthening of an interval of Q-T (risk of developing ventricular arrhythmias and lengthening of an interval of Q-T), a renal failure (KK more than 40 ml/min.), a liver failure (below class B on a scale of Chayld-Pyyu), a myasthenia, a concomitant use with terfenadiny, warfarin, digoxin.
In case of the admission of reception of a dose it is necessary to accept the passed dose as soon as possible, and the subsequent – at an interval of the 24th hour.
Зитролид® forte it is necessary to accept in 1 hour prior to or 2 hours after intake of antiacid medicines.
To take with caution to patients with a liver failure because of a possibility of development of fulminantny hepatitis and a heavy liver failure at such patients. In the presence of symptoms of an abnormal liver function (quickly accruing asthenia, jaundice, urine darkening, tendency to bleedings, hepatic encephalopathy) therapy of Zitrolidom® forte it is necessary to stop and conduct a research of a functional condition of a liver.
In a moderate renal failure (KK more than 40 ml/min.) use of azithromycin should be carried out under control of function of kidneys.
The concomitant use of Zitrolida® forte with derivatives of ergotamine and dihydroergotamine because of possible development of an ergotism is contraindicated.
At drug use, both against the background of reception, and in 2-3 weeks after the termination of treatment the development of the diarrhea caused by Clostridium difficile (pseudomembranous colitis) is possible. In mild cases there is enough cancellation of treatment and use of yonoobmenny pitches (Colestyraminum, kolestipol), in hard cases compensation of loss of liquid, electrolytes and protein, prescribing of Vancomycinum, bacitracin or metronidazole is shown. It is impossible to apply the medicines braking an intestines vermicular movement.
As lengthening of an interval of Q-T at the patients receiving macroleads, including azithromycin, at use of Zitrolida® is possible forte, it is necessary to be careful at patients with the known risk factors of lengthening of an interval of Q-T: advanced age, disturbance of electrolytic balance (hypopotassemia, a hypomagnesiemia), a syndrome of congenital lengthening of an interval of Q-T, a heart disease (heart failure, a myocardial infarction, bradycardia), a concomitant use of the medicines capable to extend Q-T interval (including antiarrhytmic Ia and III medicines of classes, tricyclic and tetracyclic antidepressants, neuroleptics, ftorkhinolona).
At use of azithromycin the development of a myasthenic syndrome or aggravation of a myasthenia is possible.
Pregnancy
of Zitrolid® forte gets through a placenta. Use at pregnancy is possible only if the expected advantage for mother exceeds potential risk for a fruit.
The feature of influence of medicine on ability to run the vehicle or potentially dangerous mechanisms
during treatment needs to be careful at control of vehicles and occupation other potentially dangerous types of activity demanding the increased concentration of attention and speed of psychomotor reactions.
