PRODROX

CEFADROXIL 125/250 Dispersible Tablets, 500mg Tablets, 125mg/5ml Oral Suspension

The World's Fastest Growing Oral Antibiotic

     PRODROX is Ist generation Cephalosporin

     PRODROX is orally active and is effective against all gm+ve and gm-ve pathogens that cephalexin is effective against.

     PRODROX incorporates a hydroxyl group with the cephalexin structure which allows greater tissue concentration for longer periods of time and improved bioavailability

PRODROX is effective against

v    Beta haemolytic streptococci

v    Staphylococci including the betalactamase producing strains

v    S.pneumoneae

v    E.coli

v    P.Mirabilis

v    Klebsiella

PRODROX is pharmacokinetically superior to cephalexin. The absorption is rapid and is not affected by the presence of food. Half life is almost twice as that of cephalexin. This allowed lesse frequency of dosing (BID).

PRODROX is highly lipid soluble and the penetration into various body systems is much better compared to cephalexin. It is excreted virtually unchanged (92%) in urine.

PRODROX is indicated in -

1.     UPPER RESPIRATORY TRACT INFECTIONS -

-         Pharyngitis - 98% cure rate as compared to 75% with cephalexin

-         Tonsilitis

-         Laryngitis

-         Otitis media

2.     LOWER RESPIRATORY TRACT INFECTIONS -

-   Acute and chronic bronchitis

-   Bronchiectasis

-   Lung abscesses

-   Pneumonia

3.     URINARY TRACT INFECTIONS

4.     SKIN & SOFT TISSUE INFECTIONS - PRODROX 1gm daily in a single dose is as effective as cephalexin 500mg four times daily.

Paediatric Infections - 95 to 100% cure rates

Orthopaedic Infections - 95 to 100% cure rates

Dosage-

Adults         -        1-2 gm/day in a single or two divided doses

Children     -        25-50mg/kg/day in a single or two divided doses
