Abstract
Two rapid, smart and validated stability indicating HPLC and TLC techniques were developed to determine atenolol (ATE) and lercanidipine HCl (LER) simultaneously in their pharmaceutical formulation. HPLC chromatographic separation was implemented by using Microsorb C18 (250 × 4.6 mm, 5 μm) column, with mobile phase of acetonitrile and 20 mM potassium dihydrogen phosphate buffer pH 3.5 adjusted by orthophosphoric acid in the ratio of (65:35, v/v) at a flow rate of 1.2 mL/min at 240 nm also the injection volume adjusted to be 30 μL. These selected conditions effectively separated ATE and LER at a retention time of 2 and 6.7 min, respectively, by isocratic elution mode without any interference from the obtained degradation products of LER. The densitometric determination was performed by using precoated silica gel 60F254 aluminum plates and chloroform, methanol and triethylamine (11.3:1.3: 0.3, by volume) as a developing system. The detection wavelength for simultaneous estimation of both drugs was 240 nm in the presence of the oxidative product of LER. The RF values for ATE and LER were 0.22 and 0.78, respectively. The calibration curves of both techniques were constructed with linearity ranges of (5-55) μg.mL-1 and (1-55) μg.mL-1 for both ATE and LER, respectively, for HPLC determination. While for TLC, the linearity ranges were (1-4) μg/band and (0.2-1.4) μg/band for ATE and LER, respectively. LER degradation products were characterized using UPLC/MS and the suggested mechanisms and degradation pathways were introduced.

Background:
Atenolol is a selective beta 1 blocker that can be used alone or in combination
with hydrochlorothiazide or with chlorthalidone for the treatment of hypertension and prevention from a
heart attack.

routine examination.
Methods:
In this method, the separation was accomplished through an Inertsil® ODS-3V C18 column
(250 mm x 4.6 mm, 5 μm), the mobile phase used was 25 mM aqueous potassium dihydrogen orthophosphate
solution adjusted to pH 6.8 by using 0.1M sodium hydroxide and acetonitrile (77 : 23, v/v),
the flow rate used was 1 ml/min and detection was achieved at 235 nm using UV.
Results:
All peaks were sharp and well separated, the retention times were atenolol degradation (ATN
Deg.) 2.311 min, atenolol (ATN) 2.580 min, hydrochlorothiazide degradation (HCT Deg.) 5.890 min,
hydrochlorothiazide (HCT) 7.016 min, chlorthalidone degradation CTD Deg 8.018 min and chlorthalidone
(CTD) 14.972 min. Linearity was obtained and the range of concentrations was 20- 160 μg/ml for
atenolol, 10-80 μg/ml for hydrochlorothiazide and 10-80 μg/ml for chlorthalidone. According to ICH
guidelines, method validation was accomplished, these methods include linearity, accuracy, selectivity,
precision and robustness.
Conclusion:

Abstract
A present study was conducted to investigate compatibility of β-blocker drugs( like atenolol, labetalol hydrochloride, bisoprolol fumarate, metoprolol succinate, carvedilol and propranolol hydrochloride) with the pharmaceutical excipient povidone. To check the influence of peroxide impurity present in povidone on the stability of β-blockers, a binary mixture technique has been adopted. The binary mixtures (1:1) of β-blockers with povidone excipient were stored for the duration of 6 months at accelerated conditions (40°C and 75% RH) and analyzed with the technique of high-performance liquid chromatography (HPLC). On analysis, HPLC results shows that, the percentage of total impurity for atenolol-2.15%, bisoprolol fumarate-3.55%, carvedilol-2.19%, and labetalol hydrochloride-1.89%, with respect to povidone. To verify the interaction of H2O2 present in povidone as an impurity, oxidative degradation of selected active pharmaceutical ingredients were performed and degradation profile were compared with that of degradation impurities generated in drug-excipient mixture at accelerated conditions. The relative retention time (RRT) of impurities generated in accelerated stability study samples resembles the RRT of degradation products generated by oxidative degradation of pure drugs. Thus, it confirms that degradation of β-blockers with povidone was mediated by organic peroxides present as an impurity in povidone.

Abstract
A sensitive, rapid and simple flow-injection chemiluminescence (CL) system based on the light emitted from KMnO4-cadmium sulfide quantum dots (CdS QDs) reaction in the presence of cetyltrimethylammonium bromide (CTAB) in acidic medium was developed as a CL probe for the sensitive determination of atenolol. Optical and structural features of CdS QDs capped with l-cysteine, which synthesized via hydrothermal approach, were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL), and UV-Vis spectroscopy. The CL intensity of KMnO4-CdS QDs-CTAB was remarkably enhanced in the presence of trace level of atenolol. Under optimum experimental conditions, there is a linear relationship between the increase in CL intensity of KMnO4-CdS QDs-CTAB system and atenolol concentration in a range of 0.001 to 4.0 mg L(-1) and 4.0 to 18.0 mg L(-1), with a detection limit (3σ) of 0.0010 mg L(-1). A possible mechanism for KMnO4-CdS QDs-CTAB-atenolol CL reaction is proposed. To prove the practical application of the KMnO4-CdS QDs-CTAB CL method, the method was applied for the determination of atenolol in spiked environmental water samples and commercial pharmaceutical formulation. Furthermore, corona discharge ionization ion mobility spectrometry (CD-IMS) technique was utilized for determination of atenolol.

JOURNAL OF ANALYTICAL METHODS IN CHEMISTRY 2012; 2012:810156. [PMID: 22567567 PMCID: PMC3335304 DOI: 10.1155/2012/810156] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/25/2011] [Accepted: 12/27/2011] [Indexed: 05/03/2023]
Abstract
Three simple and sensitive spectrophotometric methods are proposed for the determination of atenolol (ATN) in bulk drug and tablets. The methods are based on the bromination of ATN by the bromine generated in situ by the action of the acid on the bromate-bromide mixture followed by the determination of unreacted bromine by reacting with a fixed amount of either meta-cresol purple (MCP) and measuring the absorbance at 540 nm (method A) and 445 nm (method B) or erioglaucine (EGC) and measuring the absorbance at 630 nm (method C). Beer's law is valid within the concentration ranges of 1.0-20.0, 2.0-40.0 and 1.0-8.0 μg/mL for method A, method B and method C, respectively. The calculated molar absorptivities were found to be 1.20×10(4), 4.51×10(3) and 3.46 × 10(4) L/mol · cm for method A, method B and method C, respectively. Sandell's sensitivity values, correlation coefficients, limits of detection and quantification are also reported. Recovery results were statistically compared with those of a reference method by applying Student's t- and F-test. The novelty of the present study is the measurement of two different colors using MCP, that is, red-pink color of MCP in acid medium at 540 nm and yellowish-orange color of brominated MCP at 445 nm.

Stability of amlodipine besylate and atenolol in multi-component tablets of mono-layer and bi-layer types. ACTA PHARMACEUTICA 2008; 58:299-308.

Abstract
Multi-drug tablets of amlodipine besylate and atenolol were prepared as either mono-layer (mixed matrix) or bilayer tablets containing each drug in a separate layer by using similar excipients and processing. Each tablet batch was packed in strip and blister packs and kept under accelerated temperature and humidity conditions. The stability of two tablet and packaging types was compared by HPLC analysis after 0, 1, 3 and 4.5 months and expressed as the content of intact amlodipine and atenolol. The content of atenolol did not decline regardless of tablet and packaging type. Amlodipine content in bi-layer tablets decreased to about 95 and 88% when packed in strips and blisters, respectively. When prepared as mono-layer tablets, the content decreased to 72 and 32%, respectively.The study revealed that the bi-layer tablet formulation was more stable than the mono-layer type. Further, the stability was increased when the tablets were packed in aluminium strips as compared to PVC blisters.
