Hafixim 50 has the main active ingredient cefixim, a 3rd generation cephalosporin antibiotic with bactericidal effect. The bactericidal mechanism of Hafixim 50 is similar to that of other cephalosporins by binding to target proteins and causing inhibition of mucopeptide synthesis in the bacterial cell wall. The process of antibacterial activity against cefixime is the reduction of the affinity of cefixime with the target protein or may reduce the permeability of the bacterial cell membrane when using the drug.
Cefixime is highly resistant to hydrolysis of beta-lactamases encoded by genes located on plasmids and chromosomes. And studies show that the stability of beta lactamase of cefixime is higher than that of other compounds such as cefaclor, cefoxitin...
Moreover, cefixime is active both in vitro and clinically with most strains bacteria such as: gram-positive bacteria such as streptococcus pneumoniae, gram-negative bacteria such as haemophilus influenzae, E.coli ...
Not only that, cefixime is also effective against in vitro of most strains of bacteria such as streptococcus agalactiae (microbes). Gram-positive bacteria), Haemophilus parainfluenzae (gram-negative bacteria)

When entering the body, the components of Hafixim 50 with 65% of cefixime in the blood will be bound to plasma proteins. Studies have also shown that cefixime has the ability to cross the placenta. And drug concentrations can reach high levels in the bile and urine. According to statistics, after the drug enters the body, about 20% of an oral dose is excreted unchanged in the urine within 24 hours. The remaining 60% of the drug content can be eliminated through the kidneys. Furthermore, Hafixim 50 is not eliminated by hemodialysis.

Acute bronchitis and exacerbations of chronic bronchitis caused by Streptococcus pneumoniae, Haemophilus influenzae... Cases of community-acquired pneumonia but in mild and moderate form The disease is caused by uncomplicated urinary tract infections caused by E.coli, proteus mirabilis bacteria. Some cases of pyelonephritis or urinary tract infections caused by susceptible enterobacteriaceae e. However, using Hafixim 50 to treat these cases may have worse treatment results than uncomplicated urinary tract infections. Gonorrhea uncomplicated by neisseria gonorrhoeae or salmonella typhi, or dysentery caused by susceptible shigella bacteria. When using antibiotic Hafixim 50, it is necessary to isolate bacteria and make an antibiotic chart. However, the doctor may prescribe the use of Hafixim 50 before performing the antibiotic if there are signs of suspicion of the causative agent. But when the results of the antibiotic are available, the doctor needs to adjust and monitor the treatment results.

Co-administration of Hafixim 50 with probenecid increased peak cefixime concentrations and AUC and decreased renal clearance and volume of distribution. Urine glucose tests with Clinitest, Benedict's solution, Fehling's solution, and coombs' test may give positive results when the patient is taking cefixime during treatment. In summary, the safe use of Hafixim 50 determines the effectiveness of the treatment. Therefore, the patient should follow the instructions and instructions of the doctor about this drug.
