Atenolol is a beta-blocker that is cardioselective, meaning it only affects beta receptors. It is used to treat angina pectoris and high blood pressure. The HPLC and Capillary Zone Electrophoresis analytical technique was developed for the purpose of detecting and quantifying Atenolol in human plasma, according to the study paper you're reading right now. The internal standard and atenolol were recovered from the solution after being extracted from plasma using the Liquid-Liquid Extraction method. A mobile phase of 10mM sodium hydrogen phosphate, 7.3mM Sodium Lauryl sulphate (pH=3), methanol, and acetonitrile (40:57:3, v:v:v) is used, with a flow rate of 1.0ml/min. A fluorescence detector was used to detect the isolated materials, which had an excitation wavelength of 229 nm and an emission wavelength of 298 nm. With this in view, Atenolol's and the internal norm's survival times are observed to be 5.4 and 8.3 minutes, respectively. The linear correlation coefficient (R20.9992) was found in the Atenolol calibration curve. The recovery rate for atenolol and an internal norm was estimated to be between 76 and 87 percent. Solid-phase extraction was performed on an uncoated silica capillary with a diameter of 58.5 cm 75 m, and detection was performed at 194 nm in the Capillary Zone Electrophoresis procedure. For an electrolyte solution containing 50mM H3BO3 and 50mM Na2B4O7 (50:50 V/V), atenolol was determined to be present in the solution in less than 3 minutes. Energized with a voltage of 25kV and injected with a hydrodynamic configuration for 4S. Under various conditions, this method was used to assess the stability and capability of measuring Atenolol in human plasma.
