Sparfloxacin is a broad-spectrum antibacterial agent that inhibit DNA gyrase and topoisomerase IV and kills many of the types of bacteria that can infect the breathing airways and lungs and has been shown in a large number of clinical trials to be safe and effective for the treatment of bacterial infections. It is found to be more effective in vitro than other fluoroquinolones against some gram positive organisms (Streptococcus pneumoniae, Staphylococcus aureous), Mycobacteria and Chlamydia spp. Absorption : Quinoflox‚ is well absorbed following oral administration with an absolute oral bioavailability of 92%. The mean maximum plasma sparfloxacin concentration following a single 400-mg oral dose was approximately 1.3 (±0.2) µg/mL. The area under the curve following a single 400-mg oral dose was approximately 34 (±6.8) µg·hr/mL. Steady-state plasma concentration was achieved on the first day by giving a loading dose that was double the daily dose. Maximum plasma concentrations for a 200 mg dose were also achieved between 3 to 6 hours after administration with a mean of about 4 hours. Oral absorption of sparfloxacin is unaffected by administration with milk or food, including high fat meals. Concurrent administration of antacids containing magnesium hydroxide and aluminium hydroxide reduces the oral bioavailability of sparfloxacin by as much as 50%. Distribution : Upon reaching general circulation, Quinoflox‚ distributes well into the body, as reflected by the large mean steady-state volume of distribution (Vdss ) of 3.9 (±0.8) L/kg. Sparfloxacin exhibits low plasma protein binding in serum at about 45%. Sparfloxacin penetrates well into body fluids and tissues. Results of tissue and body fluid distribution studies demonstrated that oral administration of sparfloxacin produces sustained concentrations and that sparfloxacin concentrations in lower respiratory tract tissues and fluids generally exceed the corresponding plasma concentrations. The concentration of sparfloxacin in respiratory tissues (pulmonary parenchyma, bronchial wall, and bronchial mucosa) at 2 to 6 hours following standard oral dosing was approximately 3 to 6 times greater than the corresponding concentration in plasma. Concentrations in these respiratory tissues increase at up to 24 hours following dosing. Sparfloxacin is also highly concentrated into alveolar macrophages compared to plasma. Mean pleural effusion to plasma concentration ratios were 0.34 and 0.69 at 4 and 20 hours postdose, respectively. Metabolism : Quinoflox‚ is metabolised by the liver, primarily by phase II glucuronidation, to form a glucuronide conjugate. Its metabolism does not utilize or interfere with cytochrome-mediated oxidation, in particular cytochrome P450. Excretion : The total body clearance and renal clearance of Quinoflox‚ were 11.4 (±3.5) and 1.5 (±0.5) L/hr, respectively. Sparfloxacin is excreted in both the feces (50%) and urine (50%). Approximately 10% of an orally administered dose is excreted in the urine as unchanged drug in patients with normal renal function.
Always consult a registered doctor before taking any medicine. This information is for general knowledge only.
The recommended daily dose of Sparfloxacin‚ in patients with normal renal function is two 200 mg tablets taken on the first day as a loading dose. Thereafter, one 200 mg tablet should be taken every 24 hours for a total of 10 days of therapy (11 tablets). The recommended daily dose of Sparfloxacin‚ in patients with renal impairment (creatinine clearance <50 mL/min) is two 200 mg tablets taken on the first day as a loading dose. Thereafter, one 200-mg tablet should be taken every 48 hours for a total of 9 days of therapy (6 tablets).
Most of the side effects are mild to moderate in severity and transient in nature. The most frequently reported events with the recommended dosage were: Photosensitivity reaction, Diarrhea, Nausea, Headache, Dyspepsia, Dizziness, Insomnia, Abdominal pain, Pruritus, Taste perversion, QTc interval prolongation, Vomiting, Flatulence, Vasodilatation.
Sparfloxacin is contraindicated to the patients who are hypersensitive to any of its ingredient Pregnancy and lactation Glucose-6-Phosphate Dehydrogenase (G 6 PD) deficiency History of Achilles tendinitis following the use of fluoroquinolones
Aluminium and Magnesium cations in antacids and sucralfate form chelation complexes with Asaf. Concomitant use with medications known to produce an increase in the QTc interval and/or Torsade de pointes (e.g., terfenadine). Asaf does not interact with theophylline or caffeine, nor with warfarin or cimetidine. Probenecid does not alter the pharmacokinetics of Asaf.
Adequate hydration of patients receiving Asaf should be maintained to prevent the formation of a highly concentrated urine. Administer Asaf with caution in the presence of renal insufficiency. Avoid the concomitant prescription of medications known to prolong the QTc interval, e.g., erythromycin, terfenadine etc. Excessive exposure to sunlight should be avoided.
