Mechanism of Action
The major action of levofloxacin is to inhibit the DNA synthesis process of bacteria. It augments the breakage of DNA strands by restricting DNA-gyrase, which is an essential bacterial enzyme. DNA-gyrase helps in catalysing the negative supercoiling feature of closed circular double-stranded DNA, which is dependent on ATP.
Levofloxacin is reactive against gram-positive bacteria, which are penicillin-sensitive and resistant as well. It has a reduced effect on gram-negative bacilli.
It is one of the most effective antibiotics in its class and is used for a second line anti-tubercular therapy. It has high in-vitro activity. (2)
This medicine gets rapidly absorbed and evenly distributed in the body. Its bioavailability is 99% on applying either intravenously or orally. It is eliminated out through the renal route.
