Abstract:- Simple, fast and reliable derivative spectrophotometric methods were developed for determination of paliperidone in bulk and pharmaceutical dosage forms. The solutions of standard and the sample were prepared in methanol. The quantitative determination of the drug was carried out using the first derivative values measured at 248 nm and the second derivative values measured at 246 nm (n=6). Calibration graphs constructed at their wavelengths of determination were linear in the concentration range of paliperidone using 2-10 g/ml for first and second derivative spectrophotometric method. The calibration graphs constructed at their wavelength of determination were found to be linear for UV and derivative spectrophotometric methods. All the proposed methods have been extensively validated as per ICH guidelines. There was no significant difference between the performance of the proposed methods regarding the mean values and standard deviations. Developed spectrophotometric methods in this study are simple, accurate, precise, specific, sensitive, and reproducible and can be directly and easily applied to pharmaceutical dosage form.
Keywords: Paliperidone, Derivative spectrophotometric, First derivative spectrum, Second derivative spectrum.
Paliperidone is the major active metabolite of risperidone which is a widely used as atypical antipsychotic ((Sherje and Londhe 2015)). Paliperidone is a benzisoxazole derivative and approved for the treatment of schizophrenia ((Mathew, Joshi Chintankumar, and Jonils 2011)) and other psychiatric disorders. Chemically it is (Â±)-3-[2-[4-(6-fluoro- 1,2benzisoxazol-3-yl)-1-piperidinyl]ethyl]-6,7,8,9- tetrahydro-9-hydroxy-2-methyl-4Hpyrido[1,2-a]pyrimidin- 4-one with empirical formula C23H27FN4O3 and molecular weight 426.49 ((Nageswara Rao, Ganapaty, and Lakshmana Rao 2013).
Specific mechanism is not know. Its therapeutic effect may be due to combination of D2 and 5-HT receptor antagonism (Barbosa et al. 2012)). Paliperidone has an antagonistic effect on 1 and 2 adrenergic receptors and H1 histaminic receptors ((Mathew, Joshi Chintankumar, and Jonils 2011)). The drug was approved on December 20, 2006 by the United States Food and Drug Administration (FDA)
(Trivedi et al. 2013)). Extensive literature survey reveals RP-HPLC method ((Nageswara Rao, Ganapaty, and Lakshmana Rao 2013; Jadhav et al. 2011)) Extraction Procedure and Chromatographic Analysis (Trivedi et al. 2013)). Stress degradation studies ((Chaudhari et al. 2013)). UFLC method ((Bindu, Dhekale, et al. 2012)) Spectrophotometric Method (Nagar and Pradesh 2014; Davidson et al. 2007))Derivative spectrophotometry is an analytical technique of great utility for extracting both qualitative and quantitative information from spectra composed of unresolved bands, and for eliminating the effect of baseline shifts and baseline tilts(Swarnalatha et al. 2014)
Other methods for determination of paliperidone:-
Reverse phase HPLC method: – This was developed and validated for the assay of paliperidone in pure and tablets. Analysis was carried out on Shimadzu HPLC model equipped with inertsil, LC-10AT pump, inertsil ODS C-18 column variable wavelength programmable UV-Detector SPD-10AVP and rheodyne injector with 20 ÂµL fixed loop. Acetonitrile and methanol in the ratio 10:90 v/v at a flow rate of 1.0 mL/min was employed for elution and the components were detected at 235 nm at ambient temperature. The method was validated as per the ICH guidelines. The retention time for paliperidone was found to be 5.67 min. Linearity was observed in the concentration range of 20-120 ppm with correlation coefficient 0.9990. The percent of relative standard deviation of six replicate measurements was found to be 1.25 indicate that the proposed method was precise. Recovery studies were conducted at three different concentration levels within the linearity limits and the average percent of recovery was
99.56. The amount of paliperidone drug content present in tablet dosage form was determined and found to be 99.80%. Therefore, the developed method was simple, precise and accurate and can be successfully applied for the estimation of paliperidone in pharmaceutical dosage forms. (( et al. 2012)
UPLC Method: – This method is applicable to the quantification of related substances and assay of Paliperidone palmitate. Chromatographic separation was
achieved on Acquity UPLC BEH (50 mm, 2.1 mm, and
1.7 Âµm) C-18 column, and the impurities are eluted with a gradient program of runtime about 10.0 min(Chen et al. 2014)). The eluted compounds were monitored at 238 nm, the flow rate was 0.5 mL/min, and the column oven temperature was maintained at 35Â°C. The resolution of Paliperidone palmitate and eight (potential, bi-products and degradation) impurities was greater than 2.0 for all pairs of components. The high correlation coefficient (r2 > 0.999) values indicated clear correlations between the investigated compound concentrations and their peak areas within the test ranges. The repeatability and intermediate precision, expressed by RSD, were less than 10.0%. The accuracy and validity of the method were further ascertained by performing recovery studies via a spike method. The accuracy of the method expressed as relative error was satisfactory. The drug was subjected to the International Conference on Harmonization (ICH) prescribed hydrolytic, oxidative, photolytic, and thermal stress conditions. The performance of the method was validated according to the present ICH guidelines for specificity, limit of detection, limit of quantification, linearity, accuracy, precision, ruggedness, and robustness. (Bindu, Dhekale, et al. 2012)
Four simple, sensitive, rapid and accurate analytical methods have been developed for the estimation of paliperidone in bulk and pharmaceutical dosage forms.
Method I was a precise reverse phase HPLC involving an isocratic elution of Paliperidone in a column of Pkenomenex CIS, using a mobile phase composition of acetonitrile: Methanol: Potassium dihydrogen phosphate (45:30:25, v/v). The flow rate was 1.0 ml/min and the effluent was monitored at 275 nm and retention time was observedat 4.15 mm. Forced de-gradation studies were carried out in acid and basic medium,oxidative degradation
in H2O2 and as well as uv pho-to stability studies((Sherje and Londhe 2015; Bindu, Reddy, et al. 2012).
Method II & III are visible spectrophotometnc methods based on the formation of red coloured complex between Paliperidone and PDACA which showed linearity in the concentration range 20-120Âµg/ml and between Paliperidone and 4 Amino phenazone in red coloured chromogen which obeyed Beer's law 30-150 Âµg/ml at absorbance maxima of 460 nm and 532 nm respectively ((Rele 2017a; 2017b)
Method IV was a simple ultraviolet spectroscopic method was developed for the estimation of Paliperidone in 0.1N HC1 which obeyed Beer's law in the linearity range 5-25
Âµg/ml at 275 nm. The proposed methods are optimized and validated as pe the ICH guidelines (Patil and Shirkhedkar 2015). Recovery of paliperidone in the proposed methods was found to be in the range of 97.5-99.2 %. The proposed methods can be used for routine analysis for the estimation of paliperidone in formulations.

MATERIALS AND METHODS
UV and derivative spectra of the solutions were recorded on double beam UVVis spectrophotometer Shimadzu- 1800 using 10mm path length quartz cells with fixed slit width of 2 nm at a scanning speed of 1000 nm/min scan range of 200400 nm, data pitch 0.5 nm.
Paliperidone pure sample was obtained as a gift sample from RL fine chemicals ltd, Bangalore, India. Tablet
formulation (Palido OD 3, Torrent Pharmaceuticals Ltd, India) containing 3 mg paliperidone was purchased from the local pharmacy. Methanol used was of analytical grade and was purchased from Merck Chemicals, India.
SELECTION OF SOLVENT:
Paliperidone is soluble in methanol and derivative spectra of the drug showed zero crossing points. Hence methanol was selected as the solvent for the method.
PREPARATION OF STANDARD SOLUTIONS:
Stock solution of 1000 g/ml of paliperidone was prepared in methanol, for first and second derivative spectrophotometric analysis. The standard solutions were prepared by dilution of the stock solution with methanol in a concentration range of 2, 4, 6, 8 and 10 g/ml for first and second derivative spectrophotometric methods. Methanol was used as a blank solution.
A total of 20 tablets of paliperidone were accurately weighed and powdered. An amount of tablet triturate equivalent to label claim of paliperidone was weighed and transferred in 10 ml calibrated volumetric flask, diluted with methanol stirred for about 45 min and then volume made up with methanol. This solution was filtered to remove any insoluble matter. The filtrate was collected in a clean volumetric flask. Appropriate dilutions were made to obtain 10 g/ml with methanol from stock solution for both UV and derivative spectrophotometric methods( Table 7).
The proposed method was validated according to the International Conference on Harmonization (ICH) guidelines8.
Standard graphs of linearity for proposed methods Results were shown in Table 1, Table 2 and Table 3.
To evaluate the precision of the method, pure drug solution (Within the Linearity range of 2-10Âµg/ml) was analyzed and being repeated six times. The relative error (%) and relative standard deviation (%) were less than 2.0 and indicate the high precision for the proposed methods (Table 4).
L.O.Q and L.O.D
The limits of detection and quantification of the proposed method was also analysed and reported (Table 5).
To assure the reliability of the above method recovery studies were carried out by mixing a known quantity of the standard drug with the formulation sample. The recovery studies were carried out at three different levels i.e. 80 %, 100% and 120 % levels. The contents were analyzed by the proposed method for UV, first and second derivative spectroscopy (Table 6).
RESULTS AND DISCUSSION
From the standard stock solution of paliperidone, appropriate aliquots were pipetted out in to
A series of volumetric flasks and volume was made up with methanol to get concentrations of 2-10Âµg/ml. Absorbances of these solutions was measured at 279 for zero order spectroscopy, 248 for first order derivative spectroscopy and at 246 nm for second order spectroscopy.
The UV, first and second derivative spectra for paliperidone were recorded at the wavelength of 279nm, 248nm, 246 nm respectively (Figure3, Figure 5 and Figure 7). The proposed method was found that the drug obeys linearity with in concentration range of 2-10g/ml (Table 1, Table 2 and Table 3) and (Figure 2, Figure 4 and Figure
