32–0.89 for intra-day, 0.47–1.65 inter-day for TCS respectively. The

developed method was found to be precise as the % RSD values for repeatability and intermediate precision selleck products studies were <2%, as recommended by ICH guidelines. The % Assay and % RSD was found to be in range 100 ± 1.5% and <2, respectively. It indicates that method follow specification of ICH guideline. The results are given in Table 5 of short-term, long-term and the auto sampler stability of the DKP and TCS solutions were calculated from nominal concentrations and found concentration. Results of the stability studies were in the range of 99.5–101.5%. Stability as described in method development under experimental section was studied. Result of short-term, long-term and the auto sampler stability of the DKP and TCS solutions were calculated from nominal concentrations and found concentrations. Results of the stability studies were within the acceptable limit (98–102%). Simple, precise and accurate RP-HPLC-PDA method has been developed and validated for quantitative determination of DKP and TCS from tablet formulations. All the method validation parameters for the two titled drugs met the criteria of ICH guidelines for method validation. As the mobile phase C59 wnt is MS compatible, the method can

be used to determine analytes individually or in combination in biological fluids to study the pharmacokinetics and can be used for LC MS system. The method is very simple, rapid and economic in nature as all peaks are well separated, which makes it especially suitable for routine quality control analysis work.

“Gabapentin (GBP), 1-(aminomethyl) cyclo-hexaneacetic acid, is chemically unique cyclohexane derivative of gabba amino butyric acid (GABA) that was synthesized to cross blood brain barrier, and mimic

the inhibitory effects of Tolmetin this neurotransmitter on the CNS. Gabapentin is effective as adjunctive therapy for patients with partial and secondarily generalized tonic-clonic seizures.1 and 2 It is official in United State Pharmacopoeia 30.3 Methylcobalamin (MCB), (1R, 2R, 4S, 7S)-7-[(2S)-3-hydroxy-2-phenylpropanol]oxy-9,9-dimethyl-3-oxa-9-azonia tricycle [3.3.1.02,4] nonane, is a supplement for vitamin, used in treatment of Vitamin B12 deficiency of dietary origin.1 and 4 It is official in Japanese pharmacopoeia.5 Alpha lipoic acid (ALP), (R)-5-(1, 2-dithiolan-3-yl) pentanoic acid, is antioxidant, and used in treatment of diabetes and HIV.
