Levofloxacin Hydrochloride Powder Usage and Synthesis.

Levofloxacin Hydrochloride is the levorotatory form of ofloxacin, its antibacterial activity is about twice as much as that of of ofloxacin, the main mechanism of action of Levofloxacin Hydrochloride Powder is to inhibit the activity of bacterial DNA rotamase (bacterial topoisomerase Ⅱ), and impede the replication of bacterial DNA. 

Veterinary Medicine Levofloxacin Hydrochloride is characterized by wide antibacterial spectrum and strong antibacterial effect.Levofloxacin Hydrochloride is a white to light yellow crystalline powder, odorless and bitter in taste. It is slightly soluble in water.

Levofloxacin Hydrochloride Powder is suitable for the following mild and moderate infections caused by sensitive bacteria.

Uses and functions of Levofloxacin Hydrochloride Powder.

Levofloxacin Hydrochloride has strong antibacterial activity against most Enterobacteriaceae, such as Escherichia coli, Klebsiella, Serratia, Aspergillus, Shigella, Salmonella, Citrobacter, Bacillus, as well as Pseudomonas aeruginosa, Haemophilus influenzae, Gonorrhea and other gram-negative bacteria.

It also has good antibacterial effect on some methicillin-sensitive staphylococci, Streptococcus pneumoniae, Streptococcus pyogenes, hemolytic streptococci and other Gram-positive bacteria and Legionella, Mycoplasma, Chlamydia and so on. However, the effect on anaerobic bacteria and enterococci is poor.

This product is suitable for the following mild, moderate and severe infections caused by sensitive bacteria Respiratory system infections: acute bronchitis, chronic bronchitis, acute exacerbation of chronic bronchitis, diffuse fine bronchitis, bronchodilatation co-infection, pneumonia, pharyngolaryngitis, tonsillitis (peri-tonsillar abscess).

Urinary system infections: pyelonephritis, complicated urinary tract infections, etc.

Reproductive system infections: prostatitis, epididymitis, uterine cavity infection, uterine adnexitis, pelvic inflammatory disease (metronidazole can be used in combination when anaerobic infection is suspected).

Skin and soft tissue infections: infectious impetigo, cellulitis, lymphadenitis, subcutaneous abscesses, perianal abscesses. Intestinal infections: bacillary dysentery, infectious enteritis, salmonella enteritis, typhoid fever and paratyphoid fever. Other infections: trauma

Pharmacological Effects of Levofloxacin Hydrochloride Powder.

This product is off-white to light yellow crystalline powder, odorless, bitter taste. It is slightly soluble in water, very slightly soluble in ethanol, insoluble in ether; soluble in glacial acetic acid, slightly soluble in 0.1 mol/L hydrochloric acid solution.

Levofloxacin Hydrochloride (LevofloxacinHydrochloride) is the levofloxacin of oxfloxacin, its antibacterial activity is about twice as much as that of of oxfloxacin, and its main mechanism of action is to inhibit the activity of bacterial DNA splicing enzyme (bacterial topoisomerase Ⅱ), and impede bacterial DNA replication.

Production method of Levofloxacin Hydrochloride Powder.

The synthesis process of Levofloxacin Hydrochloride in the prior art, which generates Levofloxacin by condensation reaction of Levofluorocarboxylic acid and N-methylpiperazine under the action of a catalyst, and then evaporates the solvent, and crystallizes and dries in a crystallization solvent in order to produce a dry product of Levofloxacin, and then finally salts the Levofloxacin with hydrochloric acid and crystallizes it several times with ethanol in order to produce Levofloxacin Hydrochloride. The synthesis process in the prior art has the following problems:

• (1) Levofloxacin crystals need to be produced first and then salted with hydrochloric acid, which is a long and cumbersome process and not easy to operate;
• (2) The use of a catalyst in the preparation of levofloxacin introduces impurities, resulting in a lower purity of the ultimately produced levofloxacin hydrochloride, which needs to be refined again.
