6.BRIEF RESUME OF THE INTENDED WORK:
6.1.Need For The Study:
Moxifloxacin is a synthetic Fluoro quinolone antibiotic used to treat bronchitis, pneumonia, sinusitis, and certain skin infections. It is a synthetic fluoro quinolone antibiotic agent. It is also used in ophthalmology for the treatment of conjunctivitis under the name Vigamox.

(1-cyclopropyl-7-[(1S,6S)-2,8-diazabicyclo[4.3.0]non-8-yl]-6-fluoro-8-
methoxy-4-oxo- quinoline-3-carboxylic acid)
Moxifloxacin
Moxifloxacin is a water insoluble solid having the molecular formulae of C21H24FN3O4 and molecular weight of 401.431 g/mol.
Category : Fluoro quinolone Antibiotic.
.
The literature survey reveals that Moxifloxacin was analyzed quantitatively by using HPLC1,HPTLC2 and Tandem mass spectroscopy3. But there are no methods are there for the quantitative estimation of Moxifloxacin by using spectroscopy. Hence there is a need for the development of a newer, simple, sensitive and accurate spectroscopial analytical methods for the quantitative estimation of Moxifloxacin in bulk and pharmaceutical dosage forms.
6.2) REVIEW OF LITERATURE:
From previous journals and web releases:
1)  Tatar ulu.S1 has developed a sensitive high-performance liquid chromatographic (HPLC) method for the determination of Moxifloxacin in human plasma using fluorescence detection method.
2)  Shah’s etal2. have developed a new simple, sensitive, specific and precise high performance thin layer chromatographic method has been developed for estimation of Moxifloxacin in its tablet formulation.
3)  Viswanathan,k etal3. have developed a rapid, sensitive and selective method for the determination of Moxifloxacin.The method based on liquid chromatography electro spray ionization tandem mass spectrometry (LC/ESI-MS/MS) was developed and validated to quantitate Moxifloxacin in human plasma.
4)  Sanjay K. Motwani etal. have developed a simple, sensitive, selective, precise and stability-indicating high-performance thin-layer chromatographic (HPTLC) method for densitometric determination of Moxifloxacin both bulk and from pharmaceutical formulation.
5)  Sanjay K Motwani etal. developed a new, simple, cost effective, accurate and reproducible UV-spectrophotometric methods were developed and validated for the estimation of Moxifloxacin in bulk and pharmaceutical formulations.
6)  Cruz, L.A etal. have developed enantiomeric purity assay of Moxifloxacin hydrochloride by capillary electrophoresis.
7)  Boubakar B.Ba etal. have developed a new method for the development of Moxifloxacin in growth media by HPTLC.
8)  Lemonie T etal. developed a new method for the determination of Moxifloxacin in human plasma and lung tissue by HPLC with ultra violet detection using a fully automated extraction with a new polymeric cartridge.
9)  Tobin CM etal.have developed an isocratic high performance liquid chromatographic (HPLC) assay for Moxifloxacin 8-methoxy fluoro quinolone.
10) Kumar YR etal. have studied about the structural identification and characterization of impurities in Moxifloxacin.
6.3OBJECTIVE OF THE STUDY:
1.  To establish a sensitive and an accurate method for the quantitative estimation of Moxifloxacin as an active ingredient in bulk drugs by various spectrophotometric and chromatographic methods.
2.  To validate the newly developed methods in accordance with the analytical validation parameters mentioned in the USP and ICH guidelines.
3. To applying the newly developed and validated analytical method for the
Quantitative estimation of Moxifloxacin in formulations.
7. MATERIALS AND METHODS:
MATERIALS:
In the present investigation of newer analytical method development for the quantitative estimation of Moxifloxacin, the chemicals and other reagents required will be procured from standard companies. The methods will be standardized on Systronics 2201 double beam spectrophotometer and other chromatographic instruments using calibrated volumetric glass apparatus. The pure sample of Moxifloxacin for the research work will be procured from Aurobindo pharma limited, Hyderabad.
The following analytical methods are planned to develop with high sensitivity, accuracy, precision and economy.
1. Acid dye method.
2. Difference spectrophotometric method.
Acid dye method:
Since Moxifloxacin is having heterocyclic imino group it can be condensed with amine in its ionized form to an ionized acidic dye11 by acid dye method.
Eg: using Methyl orange / Bromocresol purple /cresol red etc which yields a salt (ion pair) that may be extracted into an organic solvent such as chloroform / dichloromethane. The indicator dye will be added in excess and the PH of the aqueous Solution is adjusted if necessary to a value where both the imine and the dye are in ionized forms. The ion pair is then separated from the excess indicator by extraction into the organic solvent and the absorbance will be measured.
Difference spectrophotometric method:
Difference spectrophotometric method12 is the simplest and most commonly employed technique for altering the spectral properties of the analyte having the aromatic carboxylic acid group with the adjustment of the PH by means of aqueous solutions of acids / alkali / buffers.
Eg:
Imines are dependent on the state of ionization of the functional groups and consequently on the PH of the solution.
