5 Pharmacology and Biochemistry
5.1 Pharmacology

Sparfloxacin is a synthetic fluoroquinolone broad-spectrum antimicrobial agent in the same class as ofloxacin and norfloxacin. Sparfloxacin has in vitro activity against a wide range of gram-negative and gram-positive microorganisms. Sparfloxacin exerts its antibacterial activity by inhibiting DNA gyrase, a bacterial topoisomerase. DNA gyrase is an essential enzyme which controls DNA topology and assists in DNA replication, repair, deactivation, and transcription. Quinolones differ in chemical structure and mode of action from (beta)-lactam antibiotics. Quinolones may, therefore, be active against bacteria resistant to (beta)-lactam antibiotics. Although cross-resistance has been observed between sparfloxacin and other fluoroquinolones, some microorganisms resistant to other fluoroquinolones may be susceptible to sparfloxacin. In vitro tests show that the combination of sparfloxacin and rifampin is antagonistic against Staphylococcus aureus.


5.2 MeSH Pharmacological Classification

Antitubercular Agents

Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy. (See all compounds classified as Antitubercular Agents.)


Topoisomerase II Inhibitors

Compounds that inhibit the activity of DNA TOPOISOMERASE II. Included in this category are a variety of ANTINEOPLASTIC AGENTS which target the eukaryotic form of topoisomerase II and ANTIBACTERIAL AGENTS which target the prokaryotic form of topoisomerase II. (See all compounds classified as Topoisomerase II Inhibitors.)


5.3 ATC Code

J - Antiinfectives for systemic use

J01 - Antibacterials for systemic use

J01M - Quinolone antibacterials

J01MA - Fluoroquinolones

J01MA09 - Sparfloxacin


5.4 Absorption, Distribution and Excretion

Absorption

Well absorbed following oral administration with an absolute oral bioavailability of 92%. Unaffected by administration with milk or food, however concurrent administration of antacids containing magnesium hydroxide and aluminum hydroxide reduces the oral bioavailability of sparfloxacin by as much as 50%.


5.5 Metabolism/Metabolites

Hepatic. Metabolized primarily by phase II glucuronidation to form a glucuronide conjugate. Metabolism does not utilize or interfere with the cytochrome P450 enzyme system.


5.6 Biological Half-Life

Mean terminal elimination half-life of 20 hours (range 16-30 hours). Prolonged in patients with renal impairment (creatinine clearance <50 mL/min).


5.7 Mechanism of Action

The bactericidal action of sparfloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.
