Stability-Indicating TLC-Densitometric and HPLC Methods for Simultaneous Determination of Teneligliptin and Pioglitazone in Pharmaceutical Dosage Forms with Eco-Friendly Assessment. J Chromatogr Sci 2024:bmae038. [PMID: 38836346 DOI: 10.1093/chromsci/bmae038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 05/01/2024] [Indexed: 06/06/2024]
Abstract
The combination of teneligliptin hydrobromide hydrate and pioglitazone hydrochloride in pharmaceutical formulations has improved type 2 diabetes management. Two chromatographic methods TLC-densitometry and RP-HPLC were developed for simultaneous quantification of teneligliptin hydrobromide hydrate and pioglitazone hydrochloride in pharmaceutical formulations, ensuring accuracy and stability assessment. The TLC method uses a mobile phase of methanol, toluene, ethyl acetate and triethylamine (1:7:2:0.1, v/v/v/v) on TLC silica gel plates, scanned at 268 nm. The RP-HPLC method employs isocratic elution with acetonitrile and sodium acetate buffer (adjust pH 3.6 with glacial acetic acid, 60:40 v/v) on a shimpack C18 column (250 × 4.6 mm i.d., 5 μm), detected at 235 nm. Both methods offer high accuracy and reliability, making them valuable for pharmaceutical quality control. Additionally, an environmental impact assessment was conducted using eco-scale, Analytical Greenness Metric Approach, Green Analytical Procedure Index, and national environmental method index to evaluate solvent consumption, waste generation and energy usage. Statistical comparisons (t-tests and F-tests) validate the outcomes of both methods, ensuring their effectiveness in drug formulation analysis. These methods can enhance pharmaceutical quality control while fulfilling environmental responsibilities.

Hydrophilic interaction liquid chromatography-electrospray ionization mass spectrometry combined with fabric phase sorptive extraction for therapeutic drug monitoring of pioglitazone, repaglinide, and nateglinide in human plasma.

Abstract
Polypharmacy in type 2 diabetes is an issue of major concern as the prescription of multiple medi-cations for the management of diabetes-associated comorbidities can lead to drug-to-drug interactions, which can pose serious risks to patients' health. Within this context, the development of bioanalytical methods for monitoring the therapeutic levels of antidiabetic drugs is notably useful to ensure patients' safety. In the present work, a liquid chromatography-mass spectrometry method for the quantitation of pioglitazone, repaglinide, and nateglinide in human plasma is described. Sample preparation was performed by fabric phase sorptive extraction (FPSE), and hydrophilic interaction liquid chromatography (HILIC) was implemented for the chromatographic separation of the analytes, using a ZIC®-cHILIC analytical column (150 × 2.1 mm, 3 µm) under isocratic elution. The mobile phase consisted of 10 mM ammonium formate aqueous solution (pH = 6.5)/ acetonitrile, 10/90 v/v, and was pumped at a flow rate of 0.2 mL min-1. Design of Experiments was used during the development of the sample preparation method to gain deeper insight into the effect of various experimental parameters on extraction efficiency, their potential interactions and to optimize the recovery rates of the analytes. The linearity of the assay was assessed over the ranges of 25 to 2000, 6.25 to 500, and 125 to 10000 ng mL-1 for pioglitazone, repaglinide, and nateglinide, respectively. The presented method was fully validated and can be used for the therapeutic monitoring of the targeted analytes in human plasma samples.

Kawadkar M, Mandloi AS, Singh N, Mukharjee R, Dhote VV. Combination therapy for cerebral ischemia: do progesterone and noscapine provide better neuroprotection than either alone in the treatment? NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2022; 395:167-185. [PMID: 34988596 DOI: 10.1007/s00210-021-02187-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Accepted: 11/20/2021] [Indexed: 10/19/2022]
Abstract
Ischemic stroke presents multifaceted pathological outcomes with overlapping mechanisms of cerebral injury. High mortality and disability with stroke warrant a novel multi-targeted therapeutic approach. The neuroprotection with progesterone (PG) and noscapine (NOS) on cerebral ischemia-reperfusion (I-R) injury was demonstrated individually, but the outcome of combination treatment to alleviate cerebral damage is still unexplored. Randomly divided groups of rats (n = 6) were Sham-operated, I-R, PG (8 mg/kg), NOS (10 mg/kg), and PG + NOS (8 mg/kg + 10 mg/kg). The rats were exposed to bilateral common carotid artery occlusion, except Sham-operated, to investigate the therapeutic outcome of PG and NOS alone and in combination on I-R injury. Besides the alterations in cognitive and motor abilities, we estimated infarct area, oxidative stress, blood-brain barrier (BBB) permeability, and histology after treatment. Pharmacokinetic parameters like Cmax, Tmax, half-life, and AUC0-t were estimated in biological samples to substantiate the therapeutic outcomes of the combination treatment. We report PG and NOS prevent loss of motor ability and improve spatial memory after cerebral I-R injury. Combination treatment significantly reduced inflammation and restricted infarction; it attenuated oxidative stress and BBB damage and improved grip strength. Histopathological analysis demonstrated a significant reduction in leukocyte infiltration with the most profound effect in the combination group. Simultaneous analysis of PG and NOS in plasma revealed enhanced peak drug concentration, improved AUC, and prolonged half-life; the drug levels in the brain have increased significantly for both. We conclude that PG and NOS have beneficial effects against brain damage and the co-administration further reinforced neuroprotection in the cerebral ischemia-reperfusion injury.
