Article Abstract

Spectrofluorimetry and room temperature photochemically-induced fluorescence (RTPF) have been applied to the determination of sulphacetamide (SAC), sulphaguanidine (SG) and sulphamethazine (SMT) in milk and pharmaceutical formulations. The methods are suitable for determining 0.02-0.10 micrograms ml of SAC, 0.10-0.50 micrograms ml of SG, and 0.40-1.00 micrograms of SMT.

Hypertension is the predominant risk factor for cardiovascular diseases and mortality. This study presents the first method for the simultaneous analysis of the co-administered antihypertensive drugs, Carvedilol (CAR) and Telmisartan (TEL) using a fast, highly sensitive, environmentally friendly, and cost-effective second derivative synchronous spectrofluorimetric approach. The fluorescence of CAR and TEL was quantified at 243 nm and 274.

Clonazepam, a high-potency benzodiazepine widely prescribed for seizure and panic disorders, carries a risk of abuse and dependency. This study developed a sensitive and selective spectrofluorimetric method for determining 7-aminoclonazepam, the major metabolite of clonazepam, in human urine. A 2 factorial design was employed to screen the optimal conditions for derivatization with NBD-Cl as the fluorescent label, considering factors such as pH, reagent volumes, temperature, and reaction time.

Nateglinide is an oral meglitinide that treats diabetes. Nateglinide was determined in several commercial formulations using chromatographic and spectrophotometric methods in published research. Quality-by-design approach was applied to develop the in-house nateglinide-loaded Solid Dispersion Adsorbate (SDA) for improving bioavailability and solubility.

Background: Due to the widespread use of pesticides, it is necessary to monitor surface water quality for environmental protection, industrial use and tap water production. Many analytical methods based on chromatographic separations and mass spectrometry detection can be used, but they are complex and expensive. They also require sampling and transport to the laboratory, which delays the results.
