Klacid sr pills 500mg №5

Mechanism of action

An antibiotic group macrolides. Clarithromycin inhibits protein synthesis in the microbial cell by interacting with the 50S ribosomal subunit of bacteria. Highly active against a wide range of aerobic, anaerobic, gram-positive and gram-negative bacteria.
Clarithromycin has demonstrated high in vitro activity against standard and isolated bacterial cultures. Highly effective against many aerobic and anaerobic gram-positive and gram-negative microorganisms. In vitro studies confirm the high efficacy of clarithromycin against Legionella pneumophila and Mycoplasma pneumoniae.
Drug also active against aerobic gram-positive microorganisms: Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Listeria monocytogenes; aerobic gram-negative microorganisms: Haemophilus influenzae, Haemophilus parainftuenzae, Moraxella catarrhalis, Neisseria gonorrhoeae; other microorganisms: Mycoplasma pneumoniae, Chlamydia pneumoniae (TWAR), Chlamydia trachomatis, Mycobacterium Mycobacterium leprae, Mycobacterium kansasii, Mycobacterium chelonae, Mycobacterium fortuitum, Mycobacterium avium complex (Maccoterium chelonae chelonae, Mycobacterium fortuitum, Mycobacterium leprae, Mycobacterium chelonae, Mycobacterium leprae, Mycobacterium leprae, Mycobacterium pneumoniae, Mycobacterium, Mycobacterium, Mycobacterium, Mycobacterium, Mycobacterium, Mycobacterium, Mycobacterium, Mycobacterium, Mycobacterium, Mycobacterium
To clarithromycin insensitive Enterobacteriaceae, Pseudomonas spp., As well as other gram-negative bacteria that do not decompose lactose.
The production of b-lactamase does not affect the activity of clarithromycin. Most of the methicillin and oxacillin resistant staphylococci strains are resistant to clarithromycin.
Clarithromycin has an in vitro effect on most strains of the following microorganisms (however, the safety and efficacy of using clarithromycin in clinical practice has not been confirmed by clinical studies, and the practical significance remains unclear): aerobic gram-positive microorganisms: Streptococcus agalactiae, streptococci (groups C, F, G), Streptococcus group Viridans; aerobic gram-negative microorganisms: Bordeteila pertussis, Pasteurella multocida; anaerobic gram-positive microorganisms: Сlostridium perfringens, Peptococcus niger, Propionibacterium acnes; anaerobic gram-negative microorganisms: Bacteroides melaninogenicus; Borrelia burgdorferi, Treponema pallidum, Campylobacter jejuni.
The microbiological activity of the metabolite is the same as that of the original substance, or 1-2 times weaker with respect to most microorganisms. An exception is Haemophilus influenzae, for which the efficiency of the metabolite is 2 times higher. The parent substance and its main metabolite have either an additive or a synergistic effect on Haemophilus influenzae in vitro and in vivo, depending on the bacterial culture.
Tablets of prolonged action are a homogeneous crystalline base, with the passage of which through the gastrointestinal tract provides a long-term release of the active substance.

Since the cardiovascular system: rarely, ventricular arrhythmia, including ventricular tachycardia (with an increase in the QT interval).
From the digestive system: nausea, abdominal pain, vomiting, diarrhea, gastralgia, pancreatitis, glossitis, stomatitis, oral candidiasis, discoloration of the tongue and teeth; rarely - pseudomembranous enterocolitis.Teeth discoloration is reversible and is usually restored by professional cleaning by a dentist. Liver dysfunction was rarely observed, incl. increased liver enzyme activity, hepatic cell and / or cholestatic hepatitis with or without jaundice. These abnormal liver functions can be severe, but usually they are reversible. Very rarely, there have been cases of liver failure and death mainly due to severe concomitant diseases and / or concomitant drug therapy.
From the side of the central nervous system: transient headaches, dizziness, anxiety, insomnia, nightmares, tinnitus, depersonalization, hallucinations, convulsions, fear; rarely - psychosis, confusion; in some cases, hearing loss (with the discontinuation of clarithromycin, hearing was restored), a change in smell (usually accompanied by distortion of taste sensations).
Allergic reactions: urticaria, skin flushing, pruritus, anaphylaxis, Stevens-Johnson syndrome.
From the hemopoietic system: leukopenia, thrombocytopenia.
From the laboratory indicators: increased creatinine levels in the blood; rarely - hypoglycemia (while taking hypoglycemic drugs).
Other: development of microbial resistance.

The safety of clarithromycin during pregnancy and lactation has not been studied.
It is known that clarithromycin is excreted in breast milk.
Therefore, the use of the drug Klatsid SR during pregnancy and lactation should only be in cases where there is no safer alternative, and the risk associated with the disease itself exceeds the possible harm to the mother and fetus.

WITH caution prescribe the drug to patients with impaired liver function. In the presence of chronic liver disease it is necessary to conduct regular monitoring of serum enzymes.
Also, caution should be prescribed the drug to patients with mild and moderate renal impairment. In case of marked impaired renal function (CC less than 30 ml / min), rapid-release clarithromycin should be prescribed (tablets 250 mg or 500 mg).
In the case of co-administration with Warfarin or other indirect anticoagulants, it is necessary to control the prothrombin time.

Symptoms: nausea, vomiting, abdominal pain, diarrhea. In one patient with a bipolar disorder in the history after taking clarithromycin in a dose of 8 g, mental changes, paranoid behavior, hypokalemia and hypoxemia appeared.
Treatment: unabsorbed drug should be removed from the gastrointestinal tract and symptomatic therapy should be carried out. Hemodialysis and peritoneal dialysis have no significant effect on serum clarithromycin levels.

Simultaneous administration of clarithromycin with drugs metabolized with CYP3A isoenzyme cytochrome P₄₅₀, can lead to an increase in plasma concentrations of drugs such as alprazolam, astemizol, Carbamazepine, cilostazol, cisapride, cyclosporine, disopyramide, ergot alkaloids, lovastatin, methylprednisolone, midazolam, Omeprazole, oral anticoagulants, Ip, Ip, Ip, Ip, Ip, Io, I, etc., Sildenafil, Simvastatin, tacrolimus, terfenadine, triazolam, vinblastine. A similar mechanism of interaction is noted when using drugs that are metabolized by another cytochrome P isoenzyme.₄₅₀- phenytoin, theophylline and valproate. With simultaneous use of theophylline and carbamazepine with clarithromycin, a moderate but significant (p <0.05) increase in the content of theophylline and carbamazepine in plasma was noted.
While taking clarithromycin with HMG-CoA reductase inhibitors (for example, lovastatin and simvastatin), rare cases of rhabdomyolysis are described.
With simultaneous use of clarithromycin with cisapride, an increase in the concentration of cisapride was observed. This can cause an increase in the QT interval, arrhythmia, ventricular tachycardia, fibrillation and flutter-ventricular fibrillation. Similar effects were observed in patients taking clarithromycin simultaneously with pimozide.
Macrolide drugs affect the metabolism of terfenadine. The level of terfenadine in the blood increases, which may be accompanied by an increase in the QT interval, the development of arrhythmias, ventricular tachycardia, fibrillation, and flutter-ventricular fibrillation.The content of acid metabolites of terfenadine increases by 2-3 times, the QT interval increases, but this does not cause any clinical manifestations. The same picture was observed while taking astemizole with macrolide group drugs.
There are reports of the development of trembling-ventricular fibrillation with simultaneous use of clarithromycin with quinidine and disopyramide. With the simultaneous appointment of these drugs requires monitoring of their concentration in the blood.
With simultaneous use of clarithromycin with Digoxin, an increase in the content of digoxin in serum was observed. In such patients, it is necessary to monitor the content of digoxin in serum.
With simultaneous oral administration of clarithromycin and zidovudine in HIV-infected patients, there was a decrease in the equilibrium level of concentration of zidovudine. Since clarithromycin affects zidovudine absorption, the intake of these two drugs should be separated in time.
Ritonavir significantly slows down the metabolism of clarithromycin while taking it. The value of C_max clarithromycin increased by 31%, C_min - by 182%, AUC - by 77%. A significant slowdown in the formation of 14-hydroxylarithromycin has been observed. In this case, patients without renal dysfunction do not need to adjust the dose of clarithromycin. When QA 60-30 ml / min, the dose of clarithromycin should be reduced by 50% to a maximum dose of 500 mg (1 tablet of prolonged action) 1 time / day.When taking ritonavir should not simultaneously prescribe a dose of clarithromycin more than 1 g / day.
Cross-resistance between clarithromycin and other macrolide drugs such as Lincomycin and Clindamycin may develop.
