Fosfona
Fosfona is a type of antibiotic used to treat a variety of bacterial infections. It is used to treat infections of the urinary tract caused by certain bacteria like E. coli. It can also be used to treat skin and eye infections caused by certain bacteria.
Uses For
Fosfona is used for the treatment of susceptible bacterial infections including urinary tract infections (UTI), including acute uncomplicated cystitis in women caused by Escherichia coli, proteus mirabilis, Enterococcus, Klebsiella pneumoniae, and Staphylococcus saprophyticus. It is also used for the treatment of skin and soft tissue infections caused by certain susceptible organisms.
Mechanism of Action
Fosfona works by aparticially creating enzymes in the infected bacteria cell which are used as part of the bacteria’s normal metabolic process. In the above case, the enzyme allows the bacteria to form cell wall components needed for growth. Inhibition of this process results in bacterial cell death and therefore helps to clear the infection.
How Long Does it Take to Work?
Fosfona usually starts to work within 12 to 24 hours and patients may start feeling better after a few days of taking the medication. However, it is important to take the full course of antibiotics as instructed, even if the patient feels better in order to give the medication enough time to work and to prevent the infection from coming back.
Absorption
Fosfona is rapidly and completely absorbed after intramuscular and oral administration. Intramuscular doses administered as an aqueous suspension of 1 g have produced serum concentrations of the drug which were three to five times higher than those obtained following oral therapy.
Route of Elimination
Fosfona is eliminated mainly by renal excretion, through both glomerular filtration and active tubular secretion. It is also known to be metabolized by cytochrome P450 enzymes.
