ORALUXE (F.C. Tablets / Dry Powder For Oral
Suspension)
(Cefpodoxime Proxetil)
PROPERTIES
ORALUXE (Cefpodoxime Proxetil) is an orally
administered, extended spectrum semi-synthetic
antibiotic of the cephalosporin class, belonging to the
third generation.
The bactericidal activity of ORALUXE results from its
inhibition of cell wall synthesis. Cefpodoxime has a
high degree of stability in the presence of beta-lactamases,
both penicillinases and cephalosporins of gram-negative
and gram-positive bacteria.
CLINICAL PHARMACOLOGY:
ORALUXE (Cefpodoxime Proxetil) is rapidly absorbed after
oral administration. Measurable levels were present 12
hours after administration of 100 and 200 mg at 0.08
mg/l and 0.18mg/l respectively. Over 80 % of the drug is
excreted unchanged in the urine. Increases in dosage
generally produce a proportionate increase in
Cefpodoxime urinary concentrations. Protein binding of
Cefpodoxime ranges from 22 to 33 % in serum and from 21
to 29 % in plasma, and is very well diffused in the lung
parenchyma, bronchial mucosa, pleural liquid. tonsils
and interstitial liquid.
4 to 7 hours after oral administration of 100 mg
Cefpodoxime, concentrations in the tonsils were 0.24 to
0.1
mg/gr. After administration of 200 mg Cefpodoxime,
the concentrations in the interstitial fluid were 1.5 to
2 mg/l, in the lung tissues 0.6 to 0.2
mg/gr, in the pleural liquid 0.6 to 0.8 mg/l, and
in the bronchial mucosa were around 1
mg/gr. All the above measured concentrations were
superior to the MIC.
Cefpodoxime half-life is 2.4 hours and its absorption is
about 40 to 50 % and is increased when administered with
meals.

Gram-positive:
Staphylococcus aureus (including penicillinase -
producing strains).

INDICATIONS:
ORALUXE is recommended in adults and in children (age 5
months through 12 years) for treatment of the following
infections:
- Tonsillitis, pharyngitis, sinusitis and otitis media.
- Acute, community acquired pneumonia, acute purulent
bronchitis, acute bacterial exacerbation of chronic
obstructive bronchitis.
- Acute, uncomplicated urethra and cervical gonorrhea
caused by (neisseria gonorrhoeae).
- Acute, uncomplicated anorectal infections in women due
to (neisseria gonorrhoeae).
- Uncomplicated urinary tract infections (cystitis).
- Uncomplicated skin and skin structure infections.
CONTRAINDICATIONS:
ORALUXE is contraindicated in patients with a known
allergy to Cefpodoxime or to the cephalosporin group of
antibiotics.
SIDE EFFECTS:
ORALUXE may, in some patients, cause: diarrhoea,
abdominal pain, nausea, vomiting vaginal fungal
infection, rash and headache.
PREGNANCY AND LACTATION:
Safe use of Cefpodoxime during pregnancy and lactation
have not been established.
ORALUXE should be used during pregnancy only if clearly
needed.
PRECAUTIONS:
- ORALUXE should be prescribed with caution in patients
with renal impairment.
- ORALUXE should be prescribed with caution in
individuals with previous history of allergy to
betalactamase or receiving concurrent treatment with
potent diuretics.
WARNINGS
- There is a possible allergy (in 5 to 10 % of cases) in
subjects sensitive to penicillins.
- If an allergic reaction to ORALUXE occurs, the drug
should be discontinued immediately.
Serious acute hypersensitivity reactions may require
emergency treatment measures. Pseudomembranous colitis
has been reported with the use of cephalosporin (and
other broad spectrum antibiotics): therefore, it is
important to consider its diagnosis in patients who
develop diarrhoea in association with antibiotic use.
Treatment with broad spectrum antibiotics alters normal
flora of the colon and may permit overgrowth of
clostridia. Studies indicate that a toxin produced by
clostridium difficile is one primary cause of
antibiotic-associated colitis
Cholestyramine and colestipol resins have been shown to
bind to the toxin in vitro.
Mild cases of colitis may respond to drug
discontinuation alone. Moderate to severe cases should
be managed with fluid, electrolyte, metronidazole and
protein supplementation as indicated.
When the colitis is not relieved by drug discontinuation
or when it is severe, oral vancomycin is the treatment
of choice for antibiotic-associated pseudomembranous
colitis produced by C. difficile. Other causes of
colitis should also be considered.
DRUG AND FOOD INTERACTIONS:
- Antacids (aluminum hydroxide, sodium bicarbonate) and
H2 Antagonist receptor (Ranitidine)
reduces peak plasma level by 24 to 42 % and the extent
of absorption by 27 % to 32 %
respective.
- Pentagastrin reduces the gastric pH causing an
increase of the bioavailability of the drug.
- Probenecid inhibit the excretion of Cefpodoxime and
thus increases by 31 % the A.U.C. and by 20 % the peak
plasma levels.
- Nutritional interaction: Studies indicated that the
biodisponibility of the drug increases when it is taken
with meals.
DRUG/LABORATORY INTERACTIONS:
- Positive direct Coomb's tests have been reported
during treatment with the cephalosporin antibiotics.
DOSAGE AND ADMINISTRATION:
Note: It is advisable to take ORALUXE orally with
food to enhance absorption.
ADULTS:
ORALUXE 400 mg daily, should be administered during
meals in two divided doses (BID) in the following
indications:
-Acute sinusitis.
-Acute and chronic purulent bronchitis, acute
community-acquired bacterial pneumonia, acute
bacterial exacerbation of chronic obstructive
bronchopneumonia.
ORALUXE 200 mg daily, should be administered during
meals in two divided doses (BID) in the following
indications:
- Tonsillitis, Pharyngitis.
- Uncomplicated urinary tract infections.
ORALUXE 200 mg as a single dose in uncomplicated
gonorrhoea (men and women) and rectal gonococcal
infections (women). ORALUXE 800 mg daily, should be
administered during meals in two divided doses (BID) in
skin and skin structure infections.
Dosage in renal impairment:
In patients with renal impairment (creatinine clearance
<30 ml/min) the dosage of ORALUXE should be adjusted
accordingly, to prevent drug accumulation. A dosage of
ORALUXE 100 mg daily as a single dose is sufficient.

According to the physician prescription the recommended
duration of treatment vary from 7 to 14 days.
OVERDOSAGE:
No treatment is required other than general support and
observation. For amounts greater than 50 mg/kg, induce
gastric emptying (emesis induction or gastric lava).
