Levofloxacin, sold under the brand name Levaquin among others, is a broad-spectrum antibiotic of the fluoroquinolone drug class. [6] It is the left-handed isomer of the medication ofloxacin .
See Mechanism of Action earlier.) The majority of quinolones in clinical use belong to the second generation class of "fluoroquinolones", which have a true quinoline framework, maintain the C-3 carboxylic acid group, and add a fluorine atom to the all-carbon containing ring, typically at the C-6 or C-8 positions.

β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
Levofloxacin, which is marketed under the brand name Levaquin in the U.S. and Tavanic in the EU, is often prescribed for pneumonia, urinary tract infections and infections of the abdomen.
Mechanism of action Aminoglycosides; Amikacin: Amikin: Infections caused by Gram-negative bacteria, such as Escherichia coli and Klebsiella particularly Pseudomonas aeruginosa. Effective against aerobic bacteria (not obligate/facultative anaerobes) and tularemia. All aminoglycosides are ineffective when taken orally as the stomach will digest ...
The use of clinafloxacin is associated with drug-induced light sensitivity (phototoxicity) and low blood sugar. [6] Diarrhea has also been reported. [1]The phototoxicity with clinafloxacin has been more associated with oral dosing as compared to intravenous dosing, though the studies that described this were subject to confounding by study site (that is, patients that received intravenous ...
The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
