Enhancing simultaneous determination of some angiotensin II receptor antagonists and amlodipine in plasma using HPTLC with fluorescence densitometry: Independent fluorescence detection of the co-administrative drugs in the mixture across various pH conditions.

A novel and highly sensitive high-performance thin-layer chromatographic (HPTLC) method was developed and validated to quantify a combination of five pharmaceutical mixtures spiked to human plasma. The compounds comprised Amlodipine (AML) along with five angiotensin II receptor antagonist drugs (AIIRAs), namely Olmesartan (OLM), Telmisartan (TLM), Candesartan (CAN), Losartan (LOS), and Irbesartan (IRB). HPTLC was performed on silica gel 60 F254 plates using a mobile phase of Toluene: ethyl acetate: methanol: acetone: acetic acid (6:1.5:1:0.5:1, v/v/v/v/v). In a pioneering move, a reflectance/fluorescence detection mode was employed to identify two concurrently administered drugs at different pH levels for the first time. This method utilized the same chromatographic system, incorporating a specific measurement for AML at a neutral medium to achieve its maximum fluorescence at a 360 nm excitation wavelength, and measuring emission using a 540 nm optical filter. The process involved obtaining a very low fluorescence response from AIIRA. Subsequently, to enhance AIIRA's fluorescence, the plate was sprayed with perchloric acid to transition to a strong acidic medium, ultimately attaining the maximum fluorescence of AIIRA using various excitation wavelengths and a 400 nm emission filter. Through this strategic process, we could optimize the fluorescence signals of both drugs, thereby elevating the sensitivity of detection for this drug combination. AML demonstrated a linear range of 18-300 ng/band, while AIIRAs drugs exhibited a linear range of 6-150 ng/band. The method satisfied the International Conference on Harmonization (ICH) criteria for recovery, precision, repeatability, and robustness, showcasing exceptional sensitivity. The approach was successfully applied to quantify AML and AIIRAs drugs in both bulk drug and plasma samples, achieving high recovery percentages and minimal standard deviations.

In the two spectrophotometric techniques, the absorbance of the produced ion-pair was monitored at 548 and 547 nm in aqueous buffered solution at pH 3.8 and 3.3 for Alcaftadine and Olopatadine hydrochloride, respectively. Beer's law was obeyed in the concentrations range of 0.8-8.0 and 1.0-10.0 µg mL-1. The four techniques were evaluated in accordance with ICH requirements and were effectively used to analyze dosage forms with a high percent recovery.

For the treatment of rhinitis and asthma, a combination of Montelukast sodium and Bilastine has just been approved. Based on the first derivative of synchronous fluorescence, the current work developed a green, highly accurate, sensitive, and selective spectroscopic approach for estimating Montelukast sodium and Bilastine in pharmaceutical dosage form without previous separation. The selected technique focuses on measuring the synchronized fluorescence of the studied medications at a fixed wavelength range (Δλ) = 110 nm, and using the amplitude of the first derivative's peak at 381 and 324 nm, for quantitative estimation of Montelukast sodium and Bilastine, respectively. The impacts of different factors on the referred drugs' synchronized fluorescence intensity were investigated and adjusted. The calibration plots for were found to be linear over concentration ranges of 50-2000 ng mL-1 for Montelukast sodium and 50-1000 ng mL-1 for Bilastine. Montelukast sodium and Bilastine have LODs of 16.5 and 10.9 ng mL-1, respectively. In addition, LOQs were: 49.9 and 33.0 ng mL-1, for both drugs, respectively. The developed method was successfully employed to quantify the two drugs in synthetic tablets mixture and in laboratory prepared mixtures containing varied Montelukast and Bilastine ratios. To compare the results with the published analytical approach, a variance ratio F-test and a student t-test were used, which revealed no significant differences.

Novel spectrofluorometric approach for assessing vilazodone by blocking photoinduced electron transfer: analytical performance, and greenness-blueness evaluation.

In this paper, vilazodone (VLD), a serotonin modulator prescribed for major depressive disorder, was investigated using a rapid, highly sensitive, and eco-friendly spectrofluorometric approach. The native fluorescence of VLD, originating from its indole moiety, exhibited an emission peak at 486 nm upon excitation at 241 nm. However, the presence of a piperazinyl nitrogen atom in the VLD structure, acting as an electron donor, significantly diminished the fluorescence intensity through photoinduced electron transfer (PET) to the indole ring. However, by protonating this nitrogen atom using 0.02 M Teorell-Stenhagen buffer (pH 3.5), inhibition of the PET process effectively blocked electron transfer, restoring the fluorescent properties of the drug. Further, an enhancement in the fluorescence was achieved by employing methanol as the solvent, resulting in a 1.5-fold increase. The combined use of PET blockage and methanol enabled the detection of VLD at levels as low as 0.78 ng mL-1. Calibration analysis demonstrated linearity within the range 5-400 ng mL-1, exhibiting a correlation coefficient of 0.9998 and a limit of quantification of 2.37 ng mL-1. The method obeyed the requirements of International Council on Harmonization (ICH). The proposed approach was applied for the accurate measurement of VLD in pharmaceutical tablets, content uniformity testing based on USP requirements, and determining VLD concentration in spiked human plasma. Moreover, the environmental impact, in addition to practical effectiveness, of the proposed approach was evaluated using different metrics.

The first spectrofluorimetric protocol for sensitive quantitative analysis of bromocriptine in its pure and pharmaceutical forms: evaluation of the greenness of the method.

Bromocriptine mesylate, a dopamine D2 receptor agonist, has been quantitatively determined using a sensitive, precise, quick, and affordable spectrofluorimetric method. The proposed method relies on the estimation of bromocriptine native fluorescence after the optimization of different factors to improve its inherently weak fluorescence through the use of a sodium dodecyl sulphate micellar system (2% w/v). Following excitation at 238 nm, the enhanced fluorescence intensity of bromocriptine was determined at 418 nm. As compared to its native fluorescence, the bromocriptine fluorescence intensity has been greatly enhanced by about 15 fold by employing the micellar system. The plot of intensity of fluorescence versus bromocriptine concentration was linear in the range of 50-600 ng mL-1. The method was found to have a high sensitivity, as indicated by the low limit of detection and limit of quantitation values (14.57 and 44.16 ng mL-1 respectively). Without the interference of any excipient, this method was effectively employed to quantify bromocriptine in its pharmaceutical dosage form.

Augmentation of Brexpiprazole fluorescence through photoinduced electron transfer inhibition for the sensitive spectrofluorimetric assay of pharmaceutical dosage forms and spiked human plasma: Application to content uniformity testing.

Brexpiprazole (BRX) is a new antipsychotic drug that recently was used in the treatment of schizophrenia and other psychosis. The presence of benzothiophene ring in its chemical structure makes BRX naturally fluoresces. However, the native fluorescence of the drug was low in neutral or alkaline medium owing to the occurrence of photoinduced electron transfer (PET) from the nitrogen of the piperazine ring to the benzothiophene ring. Protonation of this nitrogen atom using sulfuric acid could efficiently block PET process and thus retaining the strong fluorescence of the compound. Accordingly, a straightforward, highly sensitive, fast and green spectrofluorimetric approach was established for BRX determination. In 1.0 M sulfuric acid solution, BRX exhibited significant native fluorescence measured at emission wavelength of 390 nm after excitation at 333 nm. ICH requirements were used to evaluate the method. The fluorescence intensity and BRX concentration were found to be correlated linearly within the range of 5-220 ng mL-1 with a coefficient of correlation 0.9999. The limit of quantitation was 2.38 ng mL-1 while limit of detection was 0.78 ng mL-1. The developed approach was successfully used to analyze BRX in biological fluids and pharmaceutical dosage form. The suggested approach worked well when applied for testing the uniformity of content.

A novel and unusual utility of the cardiosintol drug as a fluoro-prober in the amendment of a highly fluorescent module for determining the non-fluorescent N-acetylcysteine drug.

It is common to use reagents to determine the drugs by exploiting the properties of these reagents in the development of fluorescence of the target drug or sometimes increasing its intensity; this is the usual and predominant in the methods used in various techniques. But using a drug as a reagent to analyze another drug is unique, unusual, and uncommon; that's the idea of this paper. This is possible by creating a chemical modulation in the drug's structure using another drug. Targeted analyte molecules (N-acetylcysteine, as an example) that lack fluorogenic or chromophoric moieties cannot be monitored or evaluated without undergoing structural modification. Thus, the chemical mending of the analyte's molecular structure can achieve the transformational process. This protocoled analytical method generates an amended fluorescence sensation that can be chased fluorimetrically at 441 nm (emission) following excitation at 339 nm. When o-dialdehyde, diformylbenzene, a non-fluorescent moiety, is added to a solution of non-fluorescent analyte in the presence of cardiosintol drug, at a specific pH, the target drug-thiol moiety can be amended into a highly fluorescent compound. This study presented a sensitive and feasible fluorometric test for acetylcysteine. The response is linear throughout the range of 0.05-0.80 µg mL-1. Quantum yield and procedure validation were evaluated according to I.C.H. standards. The formed mutated product was successfully applied to the precise assessment of the studied drug in batch powder and dose form(s), with no impact from excipients. Compared to the referenced publication, the outcomes demonstrate remarkable precision and accuracy.

The sensitivity (in terms of limit of detection and limit of quantification) was 0.003 and 0.008 µg ml-1 , indicating low toxicity. As a result, the current technology has a remarkable recovery for detecting residues in diverse bodily fluids. Also, the quantum yield was estimated for the designed system. Finally, the method was rated by eco-scale scoring.
