Mifosin is active against gram -vs bacilli sod cocci including pseudomonas, kiabsiella serratia, E. coil, shigella, sslmonetla entsrobactsr, neisseria, campylobscter, nstnrotoxigenic E. coli, haemophilua influsszas, hanmophilus parainfluenres, proteus mirabilis, proteus vulgaris, staphlococcus aureus including pencillinass producing and non producing strains and msthicitlin resistant strains) . It is moderately active against most strains of strnptococci including s. fuecalis, mycobacterium tuberculosis and clamydia trachometis. It is less active against most anaerobic bacteria. 
Mechanism of action: 
Mifosin is bactericidal and acts by inhibiting the A subunit of DNA gyrasa, a type 11 topoisomerase essential for ATP depending coiling and supercoiling of bacterial DNA. 
Mifosin is well absorbed from gastrointestinal tract after oral administration , it has bioavailsbility of approximately 70%. 
It is distributed throughout,all body tissues and fluids. Tissue concentration ascends that of serum concentration specially in the kidneys , liver, gait bladder, lungs, gynaecological tissue and proslatic tissues, It is also distributed to saliva, nasal secretions, aqueous humor, sputum skin blister fluid, lymph, peritoneel fluid, bile, prostatic secretions and broast milk, It is also distributed through skin, fat, muscles, bones and cartilage as well as cnrnbrospinal fluid. It can crossestha placenta. 
Mainly hepetic through 4 metaboliles which account for approximately 15% of an oral dose, found in urine metebolites and are active but activity is less than the unchanged ciproflosacin which is about 
- renal : approximately 50% is excreted unchanged in urine glomaruler filtration and active tubular secretion, excretion is virtually complete within 24 hours. 
- Bilisry & faecal : small amounts are excreted in bile and about 20% ix excreted in faeces within 5 days. 
- Dialysis : haumodialysix or peritoneal dialysis removes only avery smell amount, less than 10% Half life: -. 
Normal renal function is about 4 houm, with impaired renal functions it is slightly prolonged for about flto 8 hours. 
Serum, btla and urine concentrations: 
Time to peak serum concentration in fasting is about 1 to 2 hours, normally with food intake it ix about 2 hours, mean peak serum concentration afar an oral dose of 250 rag is 1.2 to 1.42 mcg)ml, after 500 mg ix 2.4 to 2.flmcglml and after 750 rag is 3.4 to 4.3 mcglml during the first 2 hours after the administration of a 250 rag dose.
