This product has a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacilli. It has good antibacterial activity in vitro against the following bacteria: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. It often has antibacterial activity against multi-drug resistant bacteria. It has high antibacterial activity against penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae and Moraxella. It has antibacterial activity against most strains of Pseudomonas such as Pseudomonas aeruginosa. This product has antibacterial activity against methicillin-sensitive Staphylococcus aureus, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good antimicrobial activity against Chlamydia trachomatis, Mycoplasma, Legionella, and also has antibacterial activity against Mycobacterium tuberculosis and atypical mycobacteria. The antibacterial activity against anaerobic bacteria is poor. Enoxacin is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death.

It has a strong antipyretic effect on rabbits with fever caused by bacterial endotoxins; it can counteract the increased permeability of capillary walls caused by xylene or histamine; it has a significant sedative effect; it can significantly promote the adrenal cortex function of rats and enhance the body's emergency response to pathogen infection; it has a certain inactivation effect on influenza virus type A1, type A3, pneumonia adenovirus (Adv) type III, type IV, enterosyncytial virus and respiratory syncytial virus (RSV) in vitro.

The effect on water and electrolyte excretion is basically the same as furosemide, and its diuretic effect is 20 to 60 times that of furosemide. It mainly inhibits the active reabsorption of NaCl by the thick wall segment of the ascending limb of the renal tubular loop of Henle, and also inhibits the reabsorption of Na+ in the proximal tubule, but has no effect on the distal tubule, so the potassium excretion effect is less than furosemide. It can inhibit the activity of prostaglandin degrading enzymes, increase the content of prostaglandin E2, and thus have a vasodilatory effect. Dilation of renal blood vessels, reduction of renal vascular resistance, and increase of renal blood flow, especially deep renal cortical blood flow, are of great significance in the diuretic effect of bumetanide, and are also the theoretical basis for its use in the prevention of acute renal failure. In addition, unlike other diuretics, loop diuretics increase the flow of renal tubular fluid while the glomerular filtration rate does not decrease, which may be related to the reduction of chloride flowing through the macula densa, thereby weakening or blocking the glomerular-tubular balance. Bumetanide can dilate the pulmonary capacitance veins and reduce the permeability of pulmonary capillaries. Its diuretic effect can reduce the amount of blood returning to the heart and the left ventricular end-diastolic pressure, which is helpful for the treatment of acute left heart failure. Since bumetanide can reduce the permeability of pulmonary capillaries, it provides a theoretical basis for its treatment of adult respiratory distress syndrome.
