Green Prospective Approach of Chromium Zinc Oxide Nanoparticles for Highly Ultrasensitive Electrochemical Detection of Anti-hypotensive Medication in Various Matrices.

A highly ultrasensitive sensor that relied on Cr/ZnO-NPs was developed to detect etilefrine hydrochloride (ETF) in different matrices via a particular green voltammetric technique. The X-ray diffraction pattern showed the nanomaterials of the polycrystalline hexagonal structure. The energy-dispersive X-ray spectrum approved the presence of Cr inside the host zinc oxide framework.

Potentiometric determination of mebeverine hydrochloride antispasmodic drug based on molecular docking with different ionophores host-guest inclusion as a theoretical study.

The scientific community has continued to pay particular attention to potentiometric sensors based on ion-selective membrane sensors as an energy-efficient, easy-to-use method suitable for microfabrication. To this end, potentiometric ion-selective sensors were used as an alternative green analytical instrument. Three distinct sensors relying on various ionophores were built and assessed.

Validated spectroscopic methods for the estimation of triamterene in bulk powder and capsule form via derivatization reactions.

Sensitive, simple and specific spectrophotometric and spectrofluorimetric methods were developed for the determination of triamterene in bulk powder and pharmaceutical dosage form. The spectrophotometric method (Method A) is based on the formation of an ion-pair complex with eosin Y in acetate buffered solution of pH 3.7 followed by measuring the absorbance at 545 nm.

Stability-indicating methods for the determination of racecadotril in the presence of its degradation products.

Three stability-indicating methods were developed for the determination of racecadotril (RCT) in the presence of its alkaline degradation products. The first was an HPLC method in which efficient chromatographic separation was achieved on a C18 analytical column and a mobile phase of acetonitrile-methanol-water-acetic acid (52:28:20:0.1, v/v/v/v).
