Besifloxacin hydrochloride Usage And Synthesis
OutlineBesifloxacin hydrochloride is developed by Bausch & Lomba as a new type of fluoroquinolones for the treatment of bacterial conjunctivitis (a non-viral caused infectious purulent eye irritation conjunctivitis ). Bacterial conjunctivitis which is a contagious eye disease, is a common disease that affects people of all ages. The clinical symptoms of infested eye including: foreign body sensation, burning sensation, tearing; conjunctival hyperemia, mucus or purulent discharge; eyelid edema, conjunctival edema and subconjunctival hemorrhage may occur in severe cases .
Besifloxacin hydrochloride ophthalmic suspensionBesifloxacin hydrochloride ophthalmic suspension (Besivance) is a fluoroquinolone drug recently approved for the topical treatment of bacterial conjunctivitis. This medicine can quickly kill common pathogens causing conjunctivitis , that is coagulase-negative staphylococci, Streptococcus pneumoniae, Staphylococcus aureus , Haemophilus influenzae bacteria, and other less common bacteria.. Besifloxacin is an effective drug to the Gram-positive and Gram-negative pathogens, include other fluoroquinolone-resistant bacteria , also it can balance the DNA gyrase and topoisomerase IV activity, slow the development of resistance. Topical administration can achieve stable and lasting high concentrations in human tears , and penetration in animal ocular tissue is good, showing excellent safety.
Pharmacokinetic and pharmacodynamic characteristics of Besifloxacin meet the criteria for successfully clearing most Gram-positive and Gram-negative bacteria, while exhibiting minimal systemic exposure.Besifloxacin biochemical properties, pharmacokinetics targeted to achieve/pharmacodynamic objectives and limited to local ophthalmic drug will slow the development of bacterial resistance, making Besifloxacin become attractive choice for acute bacterial conjunctivitis treatment.

DescriptionBesifloxacin is a new fluoroquinolone antibacterial for ophthalmic use. It is indicated for the treatment of bacterial conjunctivitis, one of the most common ocular infections encountered in the primary care setting. Although the previously marketed fluoroquinolones ciprofloxacin, levofloxacin, ofloxacin, gatifloxacin, and moxifloxacin have been widely used to treat bacterial conjunctivitis, their continued utility is hampered by the emergence of resistance among key ocular isolates such as Staphylococcus aureus. Besifloxacin is the first fluoroquinolone developed exclusively for topical ophthalmic use. Unlike the previously marketed fluoroquinolones, besifloxacin has not been used systemically and is not in development as a systemic agent. Its exclusive indication as a topical agent is expected to reduce the overall environmental exposure of bacteria to besifloxacin, which may contribute to a lower risk for the emergence of bacterial resistance. Fluoroquinolones derive their antibacterial activity via inhibition of two essential bacterial enzymes, DNA gyrase and topoisomerase IV, which regulate processes of DNA replication. Besifloxacin inhibits DNA gyrase and topoisomerase IV from Streptococcus pneumoniae (IC50 = 1 and 0.4 mg/ L, respectively) and Escherichia coli (IC50 = 1 and 10 mg/L, respectively).
