ফার্মাকোলজি

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.

সেবনবিধি

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).

পার্শ্বপ্রতিক্রিয়া

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.

সতর্কতা

Special warnings: Moderate to severe phototoxic reactions have occurred in patients exposed to direct or indirect sunlight or to artificial ultraviolet light (e.g., sunlamps) during or following treatment. Patients should be advised to discontinue Sparfloxacin therapy at the first signs or symptoms of a phototoxicity reaction such as: Sensation of skin burning Swelling Rash Itching Dermatitis Increases in the QTc interval. The safety and effectiveness of Sparfloxacin in children, adolescents (under the age of 18 years), pregnant women, and lactating women have not been established.Precaution- Adequate hydration of patients receiving Sparfloxacin should be maintained to prevent the formation of a highly concentrated urine. Administer Sparfloxacin 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.

গর্ভাবস্থায় ও স্তন্যদানকালে ব্যবহার

There are no adequate and well controlled studies in pregnant women. Sparfloxacin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
