Uses
Indications
Kaflovo drug indicated treatment in cases of bacterial infections sensitive to levofloxacin:
Like other fluoroquinolon, levofloxacin has bactericidal effects due to inhibiting the Topoisomerase II (DNA - Gyrase) and Topoisomerase IV are essential enzymes of the catalyst involved in the process of copying, code and DNA repair of bacteria. Levofloxacin is the isomers S ( -) - of Ofloxacin's isomer, it has a strong bactericidal effect about 2 times higher than ofloxacin Racemic.
levofloxacin as well as other fluoroquinolons are broad -spectrum antibiotics, which work on many gram -negative and gram -positive bacteria strains.
levofloxacin (as well as sparfloxacin) works on Gram -positive bacteria and anaerobic bacteria than other fluoroquinolon, however, levofloxacin and sparfloxacin have the effect of printing Vitro on Pseudomonas Aeruginosa is weaker than Ciprofloxacin.
antibacterial spectrum
Vitro sensitive bacteria and infections in clinically:
Gram (+) aerobic bacteria: Bacillus anthracis, Staphylococcus aureus sensitive methicilin (Meti - S), Staphylococcus coagulase negative methicilin sensitivity, streptococcus pneumonia.
Gram bacteria (-) aerobic: En
Anaerobic bacteria: peptostreptococcus, fusobacterium, propionibacterium.
Other strains: Chlamydia pneumoniae, Mycoplasma pneumonia.Vitro intermediate sensitive bacteria:
Gram (+) aerobic bacteria: Enterococcus Faecalis.
Anaerobic bacteria: Bacteroides Fragilis, Prevotella.
Levofloxacin resistant bacteria:
Gram (+) aerobic bacteria: Enterococcus Faecium, Staphylococcus aureus meti -r, Staphylococcus coagulase negative meti - r.
Diagonal resistance: In vitro, diagonal between levofloxacin and other fluoroquinolons.
Due to the mechanism of action, often without cross -resistant between levofloxacin and other antibiotics.
resistance mechanism
resistance to levofloxacin on in vitro often occurs due to mutations at the destination position on the Topoisomerase and DNA gyrase enzyme and through multi -dimensional mutations. Single mutations may only reduce the sensitivity to the drug, not clinically resistance. But multi -dimensional mutations can cause clinical resistance and cross resistance to drugs in the Quinolone group.
Antibiotic resistance mechanisms with osmotic barriers (common for pseudomonas aeruginosa) and pumping mechanism can affect levofloxacin sensitivity.
Hemocyte related relationships
The bactericidal activity of levofloxacin depends on the ratio between the maximum concentration of the drug in the serum (CMAX) and the minimum inhibitory concentration (MIC) or the ratio of the area under the curve (AUC) for MIC.
pharmacokinetic
absorption
Levofloxacin is used quickly and almost completely with the peak of plasma peaks within 1-2 hours.
Absolute bioavailability is about 99-100%. Food affects the absorption of levofloxacin. The stable stability is usually achieved within 48 hours after the dose of 500mg 1-2 times/day.
Distribution
about 30-40% levofloxacin is combined with serum protein. Levofloxacin is widely distributed in the body: bronchial mucosa, alveoli, lung, skin, prostate tissue, urine ... However, poor distribution in cerebrospinal fluid.
Metabolism
Levofloxacin is small, metabolic is desmethyl - levofoxacin and levofloxacin N - oxide. The degree of these metabolic forms is less than 5% of the doses excreted in the urine. Levofloxacin is a formal chemical stability and does not change structure.
Elimination
When using oral levofloxacin is relatively slowly eliminated from plasma (6 - 8 hours of sale time). The excretion mainly through the kidney is about 87% in the formless form and is about 12.8%. The drug cannot be removed by hemons or peritoneal.
pharmacokinetics on special subjects
For people with renal failure
pharmacokinetics of levofloxacin are affected in the case of renal failure. When the kidney function decreases, the clearance and excretion of the kidneys are reduced and the half -life of elimination. Pharmacokinetics in patients with renal failure when using single dose 500mg.
CLCR
CLCR from 20 - 49ml/minute: t = 27 hours.
CLCR from 50 - 80ml/minute: t = 9 hours.
Elderly: There is no difference in pharmacokinetics levofloxacin between young people and the elderly, unless there is a difference in creatinine clearance.
Before taking Kaflovo 500 khapharco medicine for bacterial infections, pneumonia, skin infections (10 blisters x 5 tablets)
How to use
Kaflovo medicine for oral use.
Dosage
Dosage usually uses 1 tablet/day for 7-14 days depending on the severity and pathogens
Community pneumonia: 1 tablet, 1-2 times/day for 7 - 14 days. Complex urinary tract infections: 1 tablet/day for 7-14 days. Non -complicated cystitis: 250 mg/time in 3 days. Chronic prostatitis: 1 tablet/day for 28 days. Skin infections and soft tissue: 1 tablet, 1-2 times/day for 7 - 14 days. Preventive treatment after exposure to coal bacilli Initial dose does not change when used for patients with renal insufficiency, the next dose should be adjusted according to the CLCR as follows: Patients with liver failure and older people Children Note: The above dose is for reference only. Specific dosage depends on the condition and level of progression of the disease. For a suitable dose, you need to consult a doctor or medical specialist. Symptoms The most important signs can be seen after an acute levofloxacin overdose are symptoms in the central nervous system such as confusion, dizziness, cognitive impairment, epilepsy, increased QT interval as well as stomach -gut reactions such as nausea, mucosal corrosion. Handling Because there is no specific antidote, overdose treatment by the drug right away from the stomach, adequate compensation for patients. Hematomopiaiasis and peritoneal fertilizer are not effective at levofloxacin from the body. Monitor the electrocardiogram because the distance is prolonged. What to do when you forget a dose? However, if close to the next dose, skip the forgotten dose and take the next dose at the time as planned. Note that it should not be used double the prescribed dose. What to do when overdose?
Side Effects
When using Kaflovo, you may experience unwanted effects (ADR).
Common, ADR> 1/100
Liver: Increased liver enzyme. Uncommon, 1/1000 Rare, 1/10,000 Instructions on how to handle ADR Discontinue levofloxacin in the following cases: Starting skin rash or any signs of sensitive reaction or ADR on TKTW. Monitor patients to detect fake colitis and take appropriate measures when appearing is melting while using levofloxacin. When signs of tendonitis appear to stop immediately, leave two heel tendons with appropriate fixed tools or heel brace and specialized consultation. Note: Notify the doctor the unwanted effects encountered when using the drug.
Warnings
Before using the drug you need to read the instructions carefully and refer to the information below.
Contraindicated
Kaflovo drugs contraindicated in the following cases:
History of disease in the tendon due to a fluoroquinolon. Pregnant and lactating women. The drug contains lactose, so patients with rare genetic disorders in galactose tolerance, Lactose Lapp deficiency or Glucose absorption disorders - Galactose should not use this drug. Fluoroquinolon antibiotics are associated with serious harmful reactions that can cause disabilities and non -recovery on different organs of the body. These reactions may appear simultaneously on the same patient. Harmful reactions are often recorded including tendonitis, tendon, joint pain, muscle pain, peripheral neuropathy and adverse effects on the central nervous system of the island, anxiety, depression, insomnia, severe headaches and confusion. These reactions may occur within hours to a few weeks after using the drug. Patients at any age or no risk factors that exist before may have these harmful reactions. Stop using the drug as soon as there are signs or first symptoms of any serious harmful reactions. In addition, avoid using Fluoroquinolon antibiotics for patients who have had serious reactions related to fluoroquinolon. Special tendonitis is Achille, which can lead to tendons. This complication may appear at the first 48 hours, after starting the drug and may be both sides. Tenditis occurs mainly in risks: people over 65 years old, using corticosteroids (including inhalation lines). These two factors increase the risk of tendonitis. Watch out, need to adjust the daily dosage of drugs in older patients according to glomerular filtration level. Effects on the skeletal muscle system: Levofloxacin, as well as most other quinolons, can cause cartilage degeneration in gravity joints on many young animals, so it should not be used levofloxacin for children under 18 years old. Myasthenia gravis: Caution should be cautious in patients with myasthenia gravis because the manifestations may get worse. Effects on the central nervous system: There have been notifications on adverse reactions such as mental disorders, increased intracranial pressure, stimulating the central nervous system leading to convulsions, trembling, restlessness, headache, insomnia, depression, hallucinations, nightmares, intentions, intentions or action (rare) when using Quinolon groups, even first dosage. If these adverse reactions occur while using levofloxacin, it is necessary to stop the drug and take appropriate symptomatic management measures. Be careful when used for people with central neurological diseases such as epilepsy, cerebral vascular sclerosis, ... because it may increase the risk of seizures. Hypersensitivity reactions: sensitive reaction with many other clinical manifestations, even anaphylaxis when using quinolones, including levofloxacin. It is necessary to stop the drug as soon as there are the first signs of sensitive reaction and apply appropriate treatment. Clostridium variety colitis: This adverse reaction is informed to many antibiotics including levofloxacin, which can occur at all levels from mild to life -threatening. It should be noted to accurately diagnose the cases of melting occurrence during the time the patient is using antibiotics to take appropriate treatment. Hypersensitivity to heavy -to -severe light has been informed to many Fluoroquinolon antibiotics, including levofloxacin (although up to now, this adverse reaction rate when using Levofloxacin is very low Effects on metabolism as well as other quinolones, levofloxacin can cause sugar metabolism disorders, including hyperemia and hypoglycemia often occur in people with diabetes using levofloxacin simultaneously with a hypoglycemic drug or with insulin, so it is necessary to monitor blood sugar on this patient. If hypoglycemia occurs, levofloxacin should be stopped and properly handled. Extend the QT distance on the electrocardiogram: Using Quinolones can cause a distance of qt on the electrocardiogram in some patients and some rarity of the arrhythmia, so it is necessary to avoid use in patients with long -term QT, patients with blood potassium, patients who are using anti -rhythmic drugs IA (Quinidine, Procainamid, etc.) Levofloxacin for patients who are in pace of arrhythmia such as slow rhythm and acute myocardial myocardial. The drug has an unwanted effect on the nervous system that causes dizziness, falling asleep, visual disorders, so it cannot be used for drivers and machinery. There are very few data from the use of levofloxacin in pregnant women. Animal studies do not indicate directly or indirectly about reproductive toxicity. However, because the drug has many risks of articular cartilage damage on young children, they do not use levofloxacin in pregnant women. has not measured levofloxacin levels in breast milk, but based on the ability to distribute into of Ofloxacin's breast milk, it can be predicted that it is also distributed into breast milk. Because the drug has many risks of articular cartilage damage on young children, not breastfeeding when using levofloxacin. The effect of other drugs on levofloxacin Iron salt, antacids containing magnesi or aluminum: Levofloxacin absorption is significantly reduced when using iron salt, or antacids containing magnesi or aluminum with levofloxacin. Theophylllin, fenbufen or nonsteroidal anti -inflammatory drugs: Brain seizures can be significantly reduced when used simultaneously with quinolon with theophyllin, nonsteroidal anti -inflammatory drugs, or drugs that reduce convulsions. When the presence of fenbufen concentration of levofloxacin is about 13% higher than when used. Sucralfate: Levofloxacin's bioavailability is significantly reduced when used with sucralfat. If the patient uses both sucralfat and levofloxacin, it is best to take sucralfat 2 hours after taking Levofloxacin. Probenecid and cimetidine: Through statistics, Probenecid and cimetidine have a significant influence on the elimination of levofloxacin. Levofloxacin's kidney clearance decreased by 24% due to cimetidine and 34% due to probenecid. Other drugs: Clinically studied shows that levofloxacin pharmacokinetics are not affected when used simultaneously with calcium carbonate, digoxin, glibenclamide and ranitidine. The effect of levofloxacin on other drugs Cyclosporin: Cyclosporin's waste time increases 33% when used simultaneously with levofloxacin. Vitamin K antagonistic drugs: Increasing blood clotting time (PT/INR) or bleeding, may be serious, which has been reported in patients treated with Levofloxacin in combination with vitamin K antagonists (eg warfarin). Therefore, it is necessary to monitor blood clotting tests in patients treated with antagonistic drugs. The drug extends the QT interval: Like other Flouroquinolon antibiotics, should be cautious when taking Levofloxacin simultaneously with drugs that extend QT (such as anti -arrhythmic drugs IA, III, 3 -round antidepressants, macrolid, anti -arrhythmia). Due to no studies on the correlation of the drug, not mixed with this drug with other drugs. Be cautious when using
