Chemical composition and pharmacological properties

1 ml of Hentaflox solution for injections contains enrofloxacin - 65 mg and gentamicin sulfate - 30 mg (as active ingredients), as well as excipients.

Hentaflox solution for injections is a combined antibacterial drug.

Enrofloxacin (a fluroquinolone compound) is active against most of gram-positive and gram-negative bacteria (including Pseudomonas aeruginosa, Klebsiella spp., Escherichia coli, Enterobacter spp., Campylobacter spp., Shigella spp., Haemophilus spp., Salmonella spp., Aeromonas spp., Proteus mirabilis, Staphylococcus spp., Mycoplasma spp. and Chlamydia spp.). Mechanism of enrofloxacin antibacterial action involves bacterial DNA gyrase inhibition.

Enrofloxacin easily absorbs from injection site and penetrates within most of organs and tissues. It obtains peak blood concentration in 0.5-1 hour after parenteral administration. Therapeutic concentration remains within 24 hours. Enrofloxacin is partially metabolized in liver with further formation of active metabolite (ciprofloxacin). It is excreted, mainly, 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 (including Streptococcus spp., Staphylococcus spp., Escherichia coli, Proteus spp., Enterobacter spp., Klebsiella pneumonia, Shigella spp., Pseudomonas aeruginosa, Clostridium spp., Treponema hyodysenteriae, Corynebacterium spp.). Mechanism of gentamicin antibacterial action involves protein synthesis inhibition at ribosomal level of microbial cell.

Gentamicin rapidly absorbs from injection site and distributes within most of organs and tissues. It obtains peak concentrations in 0.5-1 hour after parenteral administration. Mainly, it is excreted unchanged in urine.


Use Hentaflox solution for injections to treat calves, sheep, goats and pigs with infections of gastrointestinal tract, respiratory and urogenital systems, joints, soft tissues and skin (including atrophic rhinitis, bronchial pneumonia, colibacillosis, salmonellosis, pasteurellosis,
mycoplasmosis, mastitis-metritis-agalactia syndrome), as well as other primary and secondary bacterial infections, agents of which are susceptible to enrofloxacin and gentamicin.


Increased individual sensitivity to the drug components, frank hepatic and/or renal impairment. Do not use in pregnant and lactating females, as well as in newborn animals. It is not allowed to use in milking animals with esculent milk.

Do not use Hentaflox in combination with bacteriostatic antibiotics (levomycetin, macrolides, tetracyclines, sulfanilamides) due to potential antagonistic effect, theophyllin, polyether ionophores, nonsteroidal anti-inflammatory drugs.


Use Hentaflox solution for injections once a day in dose of 0.5 ml per 10 kg of body weight:
• pigs - intramuscular administration within 3-7 days, sows - within 1-2 days (mastitis-metritis-agalactia syndrome);
• sheep, goats and calves - subcutaneous administration within 3-5 days.
Due to potential pain reaction, maximum volume of the drug to be administered in the same site is 5 ml (sheep, goats, calves and pigs) and 2.5 ml (piglets).
