A novel antipsychotic medication named brexpiprazole (BRX) is currently employed for the treatment of schizophrenia and other psychotic disorders. Because BRX’s molecular structure includes a benzothiophene ring, it natively fluoresces. To detect BRX with precision and speed, a flow injection-fluorometric method, which is both sensitive and selective, is recommended. The fluorescence detection was conducted at 364 nm following excitation at ... Read more

People frequently administer Tizanidine (TIZ) to treat spasticity resulting from diseases like multiple sclerosis or spinal cord injuries. It also helps prevent muscle spasms. It helps to relax and release tense and stiff muscles by inhibiting specific nerve signals in the brain and spinal cord. The technique employed in this study made use of the unique ability of benzofurazan to ... Read more

A novel and selective High Performance Thin Layer Chromatographic (HPTLC) method was developed for the simultaneous determination of triamterene (TRM) and losartan (LOS) in their pure forms and spiked human plasma using fluorescence detection. The challenge of differing optimal pH values for maximum fluorescence in TRM and LOS detection was addressed by devising a strategy for detection in various pH ... Read more

tamsulosin hydrochloride (TAM) and tolterodine tartrate (TTD) in pharmaceutical formulations. The method effectively separates the drugs using an ODS column and gradient elution at a flow rate of 1.0 mL/min. Fluorescence detection was used to measure the relative fluorescence intensity (RFI) of the analytes, with excitation and emission wavelengths set at 280 nm and 350 nm, respectively. The retention times ... Read more

A new combination of silodosin and mirabegron has recently obtained approval in the Indian market for addressing the benign prostatic hyperplasia symptoms associated with overactive bladder syndrome. In this study, we present four validated UV-spectrophotometric methods that rely on straightforward mathematical calculations for the quick and simultaneous assay of MRB and SLD in commercial tablets and synthetic mixes without the ...

A straightforward and sensitive spectrofluorimetric approach was established for the determination of heptaminol hydrochloride (HTM-HCl) based on the derivatization of the drug through its reaction with 5-dimethylaminonaphthalene-1-sulfonyl chloride (Dansyl chloride). The reagent underwent a nucleophilic substitution of its chlorine atom with HTM to give N-(5-dimethylaminonaphthalene-1-sulfonyl)-6-amino-2-methylheptan-2-ol. The highly luminescent derivative was extracted using methylene chloride and subjected to analysis at an ... Read more

A novel, environmentally friendly, and sensitive HPTLC method has been developed and validated for simultaneous quantification of duloxetine (DLX) and tadalafil (TDL) in their pure state, laboratory prepared mixtures, and spiked human plasma. This method is particularly important for patients dealing with depression and sexual issues, as it allows for the measurement of these co-administered antidepressant and sexual stimulant drugs ...

A recently developed antipsychotic drug, lurasidone, was determined using a simple, sensitive, and eco-friendly spectrofluorimetric approach. The suggested approach was based on the quantifiable quenching impact of lurasidone on the inherent fluorescence of erythrosine B in an acidic environment employing a Teorell–Stenhagen buffer (pH 4). Following excitation at 530 nm, the quenching of erythrosine B fluorescence was monitored at 552 ... Read more

The appearance of multidrug-resistant Gram-negative bacterial infections, along with the lack of newly discovered antibiotics, resulted in the return to old antimicrobial medications like Polymyxins. As a result, the suggested technique aims to develop a fast, environmentally friendly, and sensitive fluorimetric method for quantifying Polymyxin B. The investigated approach depends on generating a highly fluorescent derivative by a condensation pathway ... Read more
