Each 5 mL of VANTIN Oral Suspension contains cefpodoxime proxetil equivalent to 50 mg or 100 mg of cefpodoxime activity after constitution and the following inactive ingredients: artificial flavorings, butylated hydroxy anisole (BHA), carboxymethylcellulose sodium, microcrystalline cellulose, carrageenan, citric acid, colloidal silicon dioxide, croscarmellose sodium, hydroxypropylcellulose, lactose, maltodextrin, natural flavorings, propylene glycol alginatebenzoate, starch, sucrose, and vegetable oil.CLINICAL PHARMACOLOGY Absorption and Excretion: Cefpodoxime proxetil is a prodrug that is absorbed from the gastrointestinal tract and de-esterified to its active metabolite, cefpodoxime.Following oral administration of 100 mg of cefpodoxime proxetil to fasting subjects, approximately 50% of the administered cefpodoxime dose was absorbed systemically.

Over the recommended dosing range (100 to 400 mg), approximately 29 to 33% of the administered cefpodoxime dose was excreted unchanged in the urine in 12 hours.There is minimal metabolism of cefpodoxime in vivoEffects of Food: The extent of absorption (mean AUC) and the mean peak plasma concentration increased

administered with food.Following a 200 mg tablet dose gher than under fasting conditions, and the peak plasma concentration averaged 3.1 mcg/mL in fed subjects versus 2.6 mcg/mL in fasted subjects.Time to peak concentration was not significantly different between fed When a 200 mg dose of the suspension was taken with food, the extent of absorption (mean AUC) and mean peak plasma concentration in fed subjects were not significantly increase in TProxetil Film-coated Tablets: Over the recommended dosing range (100 to 400 mg), the rate and extent of cefpodoxime absorption exhibited dose-dependency; dose-normalized C and AUC decreased by up to 32% with increasing dose.Over the recommended dosing range, the Tapproximately 2 to 3 hours and the T ranged from 2.09 to 2.84 hours.

Mean C1.4 mcg/mL for the 100 mg dose, 2.3 mcg/mL for the 200 mg dose, and 3.9 mcg/mL for the 400 mg dose.In patients with normal significant changes in other pharmacokinetic parameters were noted following multiple oral doses of up to 400 mg Q 12 hours.Tonsil Tissue:Following a single, oral 100 mg cefpodoxime proxetil film-coated maximum cefpodoxime concentration in tonsil tissue averaged 0.24 mcg/g at 4 hours post-dosing and 0.09 mcg/g at 7 hours post-dosing.Equilibrium was achieved between


No detection of cefpodoxime in hours after dosing.These results demonstrated that concentrations of cefpodoxime exceeded the MICafter dosing of 100 mg of cefpodoxime proxetil.Lung Tissue:Following a single, oral 200 mg cefpodoxime proxetil film-coated maximum cefpodoxime concentration in lung tissue averaged 0.63 mcg/g at 3 hours post-dosing, 0.52 mcg/g at 6 hours post-dosing, and 0.19 mcg/g at 12 hours post-dosing.

The results of this study indicated that cefpodoxime penetrated into lung tissue and produced sustained drug concentrations for at least 12 hours after dosing at levels that exceeded the MIC for S.pneumoniae and H.influenzae.CSF:Adequate data on CSF levels of cefpodoxime are not available.Elimination of cefpodoxime is reduced in paimpairment (50 mL/min creatinine clearance).

ABSTRACT: The present manuscript describe simple, sensitive, rapid, accurate, precise and economical first derivative spectrophotometric method for the simultaneous determination of ofloxacin and cefpodoxime proxetil in combined tablet dosage form.The derivative spectrophotometric method was based on the determination of both the drugs at their respective zero crossing point (ZCP).The first order derivative spectra was obtained in methanol and the determinations were made at 236.4 nm (ZCP of cefpodoxime proxetil) for ofloxacin

and 208.8 nm (ZCP of ofloxacin) for cefpodoxime proxetil.The linearity was obtained in the concentration range of 2-12 ofloxacin and 4-24 for cefpodoxime proxetil.

The mean recovery was 99.80

1.50 and 99.90

0.36 for ofloxacin and cefpodoxime proxetil, respectively.The method was found to be simple, sensitive, accurate and precise and was applicable for the simultaneous determination of ofloxacin and cefpodoxime proxetil in pharmaceutical tablet dosage form.The results of analysis have been validated statistically and by recovery studies.

method is available for the simultaneous estimation of OFLO and CEFPO in their combined dosage forms.

Literature survey does not reveal any simple spectrophotometric or other method for simultaneous estimation of OFLO and CEFPO in combined dosage forms.The present communication describes simple, sensitive, rapid, accurate and economical spectrophotometric method based on dual wavelength spectrophotometric method for simultaneous estimation of both drugs in their combined tablet dosage forms.MATERIALS AND METHODS Apparatus A double beam UV/Visible spectrophotometer (shimadzu model 1700, Japan) with spectral width of 2 nm, wavelength accuracy of 0.5 nm and a pair of 10 mm matched quartz cell was used to measure absorbance of all the solutions.Spectra were automatically obtained by UV-Probe system software.An analytical balance (Sartorius CP224S, Gottingen, Germany), an ultrasonic bath (Frontline FS 4, Mumbai, India) was used in the study.

Reagents and Materials OFLO and CEFPO bulk powder was kindly gifted by Acme Pharmaceuticals Ltd.Ahmedabad, India.The commercial fixed dose combination product was procured from the local market.Methanol AR Grade was procured from S.

D.Fine Chemicals Ltd., Mumbai, India.

Preparation of standard stock solutions An accurately weighed quantity of OFLO (10 mg) and CEFPO (10 mg) were transferred to a separate 100 ml volumetric flask and dissolved and diluted to the mark with methanol to obtain standard solution having concentration of OFLO (100 ) and CEFPO (100 ).Methodology The standard solutions of OFLO (10 g/ml) and CEFPO (10 g/ml) were scanned separately in the UV range of 200-400 nm.

The zero-order spectra thus obtained was then processed to obtain first-derivative spectra.Data were recorded at an interval of 1 nm.The two spectra were overlain and it appeared that OFLO showed zero crossing at 208.8 nm, while CEFPO showed zero crossing at 236.4 nm.At the zero crossing point (ZCP) of OFLO (208.8 nm), CEFPO showed a first-derivative absorbance, whereas at the ZCP of CEFPO (236.4 nm), OFLO showed a first-derivative absorbance.

Hence 236.4 and 208.8 nm was selected as analytical wavelengths for determination of OFLO and CEFPO, respectively.These two wavelengths can be employed for the determination of OFLO and CEFPO without any interference from the other drug in
