【Pharmacology and Toxicology】
Sparfloxacin is a broad-spectrum fluoroquinolone antibiotic that acts by inhibiting bacterial DNA gyrase (a topoisomerase of bacteria that controls DNA topology and is involved in DNA replication, repair, inactivation, and transcription) Activity.
This product is different in chemical structure and action form from β-lactam antibiotics. Therefore, it is still effective against bacteria resistant to β-lactam antibiotics.
Although cross-resistance has been found between this product and other fluoroquinolone drugs, some microorganisms resistant to other fluoroquinolones are still sensitive to this product.
Animals in vitro and clinical infection treatment confirmed that this product has antibacterial activity against the following bacteria:
Gram-positive aerobic microorganisms: Staphylococcus aureus, Streptococcus pneumoniae (strain sensitive to penicillin).
Gram-negative aerobic microorganisms: Escherichia coli, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, and Moraxella catarrhalis.
Other microorganisms: Chlamydia pneumoniae, Mycoplasma pneumoniae.
Although the following microorganisms have antibacterial effects in vitro, their clinical significance is still unclear.
Gram-positive aerobic microorganisms: Streptococcus agalactiae, Streptococcus pneumoniae (penicillin-resistant strain), Streptococcus pyogenes, and the like.
Gram-negative aerobic microorganisms: nitrate-negative Acinetobacter, Acinetobacter ruta, F. fulvus, Enterobacter aerogenes, Klebsiella oxytocin, Legionella pneumophila, Morganella, singular Proteus, common Proteus.
Genotoxicity: This product has no mutagenic effect on most of the Salmonella typhimurium strains (TA100, TA1535, TA1537), Escherichia coli WP2uvrA and Chinese hamster lung cells in the Ames test, but this product and other quinolones have been confirmed. Salmonella typhimurium strain TA102 has mutagenic effects and induces DNA repair in E. coli, probably because these drugs inhibit bacterial DNA gyrase. This product can induce chromosomal aberrations in Chinese hamster lung cells in vitro cytotoxic concentration, but after oral administration of this product, no chromosomal aberrations or increased micronucleus of mouse bone marrow were observed.
Reproductive toxicity: In terms of body surface area, rats, rabbits, and monkeys were administered orally at a dose of 6.4, 4.4, and 2.6 times the maximum dose of humans (the plasma concentrations of monkeys and rats were 4.5 and 6.5 times higher than those of humans, respectively). No teratogenic effects were observed. This product has no fertility or reproductive function in female or male animals when it is administered at a dose of 15.4 times the maximum dose (400 mg) of the human body (calculated as body surface area, which is equivalent to 12 times the maximum plasma concentration of humans). influences. The above doses are markedly toxic to the mothers of rabbits and monkeys and have mild maternal toxicity in rats. A dose-dependent defect in the embryonic ventricular septum was seen when the pregnant rats were dosed at a dose that showed significant maternal toxicity (equivalent to 9.3 times the human body maximum dose). In the test of three animals, the injury was specific to the rat. Since there is no adequate and strictly controlled study in pregnant women, it can only be used during pregnancy when the trade-offs affect the fetus for more than the disadvantages.
This product can be secreted from human milk. Because breast-feeding mothers take this product and have serious adverse reactions to the baby, after considering the importance of the drug to the mother, decide whether to stop breastfeeding or stop using the drug.
Carcinogenicity: No carcinogenicity was observed when mice or rats were orally administered daily for 3.5 to 6.2 times (calculated as body surface area) equivalent to the maximum dose of human (400 mg).
Others: It has been confirmed that the adult dog is orally administered with a dose of 25 mg/kg/day for 7 consecutive days (calculated as body surface area, which is equivalent to 1.9 times the highest dose of human), which can cause joint disease. The dog's weight-bearing joints show a small range of cartilage corrosive damage. Other quinolone drugs can also be seen in different types of underage animals and other signs of joint disease.
When a healthy adult has a single oral dose of 0.4 g of this product, about 5 hours after taking the drug, the plasma drug concentration reaches a peak value of 1.49±0.17 μg/L, and the elimination half-life is longer, about 16 hours.
According to the literature, this product is mainly absorbed in the small intestine after oral administration, and the stomach is hardly absorbed. The plasma protein binding rate of this product is 42 to 44%. When a single person is orally administered 150 mg of this product, the plasma drug concentration peaks at 1.72 μg/mL, and the average elimination half-life is about 26 hours. This product is widely distributed in the body after oral absorption, mainly distributed in the gallbladder (about 7 times the plasma drug concentration); followed by skin, prostate, uterus, ovary, ear, nose, throat tissue, sputum, prostatic fluid, urine and In milk (about 1.5 times the concentration of plasma drug); again saliva, tears (about 0.7 to 0.8 times the concentration of plasma drug); the lowest is aqueous humor and spinal fluid.
For 72 hours after a single oral administration of 200 mg of this product in healthy adults, 12% of the drug was excreted from the urine with a prototype drug and 29% with a glucuronic acid conjugate, and 51% was excreted from the feces by a prototype drug.
This product and antacid (such as aluminum hydroxide gel) combined with the use of this product alone, the plasma half-life is about the same, the plasma drug concentration peak and the area under the curve decreased by 21% and 35%.
When a healthy adult and a patient use this product together with theophylline, this product does not affect the concentration of theophylline in the plasma.
