Chemical composition and pharmacological properties

1 ml of Hentaflox solution for oral use contains enrofloxacin - 100 mg and gentamicin sulfate-50 mg (as active ingredients), as well as excipients.

Hentaflox solution for oral use is a combined antibacterial drug.

Enrofloxacin (an antibacterial fluroquinolone drug) is active against most of gram-positive and gram-negative bacteria, mycoplasmas and chlamydias. Mechanism of enrofloxacin antibacterial action involves bacterial DNA gyrase inhibition. After oral administration enrofloxacin easily absorbs in gastrointestinal tract, penetrates in blood and distributes within organs and tissues. It obtains peak serum concentration in 1.5-2 hours after use. Therapeutic concentration remains within 24 hours after oral administration. Enrofloxacin is partially metabolized in liver with further formation of active metabolite (ciprofloxacin). It is mainly excreted unchanged and partially as metabolites in urine and bile, as well as in milk of lactating females.

Gentamicin sulfate (an aminoglycoside antibiotic) is active against most of gram-positive and gram-negative bacteria. Mechanism of gentamicin antibacterial action involves protein synthesis inhibition at ribosomal level of microbial cell. After oral administration gentamicin sulfate slightly absorbs within intact intestinal wall; gentamicin adsorption increases due to inflammatory process in damaged intestinal mucosa. Mainly, it is excreted unchanged in feces.
