Spectrophotometric approach for deconvolving overlapped spectra of antihypertensive drug mixtures using UV detection: an eco-friendly method.
Article in BMC chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study presented four simple, environmentally friendly, chemometric methods for the determination of Amlodipine besylate and Telmisartan, When analyzed together, these drugs exhibit spectral overlapping; therefore, by adopting spectral manipulation, drugs are quantified simultaneously. The methods are namely the first derivative spectrophotometric method, the ratio difference method, the first derivative ratio method and the amplitude factor method. The methods showed detection limits ranging from 0.1211 to 0.4304 µg/mL and 0.0773 to 0.5640 µg/mL for Amlodipine besylate and Telmisartan, respectively, with good adherence to International Council for Harmonization standards. The methods were compared with the reported HPLC method using the student t-test and F-test, where the results showed no significant difference. For this method, a green solvent such as propylene glycol is selected through the Green solvent selection tool with a greenness score of 7.8 and the sustainability of the solvent is evaluated using spider diagram. Methods were assessed for their eco-friendliness and sustainability using novel tools such as Blue Applicability Grade Index, Green Analytical Procedure Index and RGB model with respect to White and Green analytical chemistry principles. Using Greenness tools for this UV-spectroscopy method improves both safety and effectiveness compared to expensive and laborious HPLC techniques. Hence, this study suggests employing easy and renewable UV spectrophotometric technologies for traditional analysis.
