“…Also, under the same condition, when the simultaneous determination of the different concentrations of ALP in the presence of 5-45 μg/mL LSD, we selected 215, 254, and 277 nm where LSD has a zero-crossing point at these wavelengths, as shown in Figure 5. The LSD and ALP concentration range was selected according to the zero-crossing point [16]. Based on this, the peak to baseline [17] can be used to measure LSD concentrations separately or simultaneously at 203, 207, and 231 nm and ALP at 215, 254, and 277 nm.…”

A new fast and simple selective method for the simultaneous determination of lisinopril dihydrate and amlodipine in combined drugs was developed using the fourth derivative spectrum method, based on the zero-crossing-point technique for the determination of compounds in drugs. The wavelength values for lisinopril dihydrate and amlodipine in solvent medium were found to be (203, 207, and 231 nm) and (215, 254, and 277 nm), respectively, with the average obeying Beer’s law in the range of lisinopril dihydrate 2.0 to 45.0 µg/mL and amlodipine 2.0 to 35.0 µg/mL. Lisinopril dihydrate has molar absorptivity regions (9227.76-11700.28 L/mol.cm, 203 nm), (15320.74-20795.59 L/mol.cm, 207 nm), and (2207.60-3311.40 L/mol.cm, 231 nm), while amlodipine (5886.72-10914.96 L/mol.cm, 215 nm), (5518.8-6418.16 L/mol.cm, 254 nm) and (1676.08-1921.36 L/mol.cm, 277 nm). The recovery rate of lisinopril dihydrate in the pharmaceutical dosage forms range was 95.13 to 102.60% and amlodipine 95.14 to 102.80%. The results of the relative error showed that the interferences did not affect the method of estimating these compounds. The proposed method has been successfully applied to estimate pharmaceutical dosage forms.

“…These include voltammetry methods for ATE analysis in pharmaceutical products (Moraes et al, 2016) and urine (Afonso et al, 2016), GC-MS method for the analysis of ATE and bisoprolol in human bone (Fernandez-Lopez et al, 2019), and UPLC-MS for the analysis of ATE and chlorthalidone in human plasma (Shah et al, 2016). Also, different mixtures containing ATE were analyzed using HPLC methods (Anderson et al, 2017;El-Alfy et al, 2019;Elkady et al, 2020;Kannappan & Mannemala, 2016) in addition to spectrophotometry (Antakli et al, 2020;Mohammad et al, 2019;Saleem, 2019;Vaikosen et al, 2020) and capillary electrophoresis (Kuraeva et al, 2016). Tabrizi et al (Tabrizi & Yousefzadeh, 2019) developed a spectrofluorimetric method for the determination of ATE and carvedilol in pharmaceutical preparations, while Damiani et al developed a spectrofluorimetric method for the determination of ATE in human urine by emissionexcitation fluorescence matrices (Damiani, 2011).…”

An environment-friendly, sensitive, simple, and economic spectrofluorimetric method for the analysis of atenolol in pure powder, pharmaceutical preparations, and urine using green solvents was developed. The analysis was carried out using the solvent 0.02 N NaOH to reach the concentration range of 30-800 ng/ml, and fluorescence intensities were measured at 301±1nm after excitation at 255 nm using a slit width of 5 nm. The effects of different solvents, different pHs, and different concentrations of NaOH were studied. The method was applied successfully to pharmaceutical tablets and spiked urine samples. The proposed method was applied to investigate the urinary excretion pattern of atenolol in a healthy male volunteer after oral administration of a 50 mg single dose. Urine samples were collected at intervals for up to 24 hours. The method was validated according to the ICH guidelines, proving that it is accurate, specific, precise, and robust. So, it is suitable for quality control analysis of atenolol and for the detection of drug abuse in precision sports due to its sensitivity for the determination of atenolol on a regular basis at therapeutic urine levels. The method complies with the principles of green analytical chemistry due to its short analysis time, high sensitivity, low cost, simple instruments, small energy consumption, very little waste, and being free from harmful solvents, ensuring operator safety. The proposed method's high level of greenness was proved by its high eco-scale score (95 points) as well as by the GAPI and AGREE greenness assessments.

The goal of this research is to develop a high-performance liquid chromatography method for analyzing atenolol levels in rabbit plasma and apply this method to the pharmacokinetic study. The liquid-liquid extraction technique was used to prepare blood samples from rabbits. Separation of atenolol was achieved on an Ace C18 column. The method’s calibration curve was plotted between 5 and 250 ng/mL. The accuracy results were better than 2.97% and the precision results were less than 6.30% in rabbit plasma for atenolol. The method had recovery values >95.8% for all samples in rabbit plasma. In addition, the validated method was used to study atenolol pharmacokinetics in rabbits. The maximum atenolol plasma concentration is 240.1 ± 33.41 ng/mL. The duration to attain the greatest atenolol concentration and the area under the curve from (AUC0-12 h) were 3.0 ± 0.64 h and 1184.1 ± 235.13 ng/mL h, respectively.
