  • Spectrofluorometric Determination of Some Β-Blockers in Tablets And

Abdine, M. A. Sultan, M. M. Hefnawy, F. Belal Received April 16, 2004, accepted June 2, 2004 Prof. Dr. F. Belal, Department of Pharmaceutical Chemistry, College of Pharmacy, P.O.Box 2457, King Saud University, Riyadh 11451, Saudi Arabia [email protected] Pharmazie 60: 265–268 (2005) A simple and sensitive spectrofluorometric method was developed for the quantitative determination of some b-blockers, namely arotinolol, atenolol and labetalol as hydrochloride salts. The method is based on the reaction of these drugs as n-electron donors with the fluorogenic reagent 9,10-dimethoxy-2- anthracene sulfonate (DMAS) as p-acceptor in acidic medium. The obtained ion-pairs were extracted into chloroform and measured spectrofluorometrically at 452 nm after excitation at 385 nm. The fluor- escence intensity-concentration plots are rectilinear over the ranges of 0.5–5 mg Á ml1, 1.0–11.0 mg Á ml1 and 0.6–6.4 mg Á ml1 for labetalol, atenolol and arotinolol, respectively. The different parameters affect- ing the reaction pathway were thoroughly studied and optimized. No interference was observed from the common pharmaceutical excipients. The proposed method was successfully applied to the analy- sis of tablets and the results were statistically compared with those obtained by reference methods. The method was further extended to the in vitro determination of the drugs in spiked human plasma, the% recoveries (n ¼ 3) ranged from 96.98 Æ 1.55 to 98.28 Æ 2.19.

  • Alpha^ and Beta^Blocking Agents: Pharmacology and Properties
    CURRENT DRUG THERAPY DONALD G. VIDT, MD AND ALAN BAKST, PharmD, EDITORS Alpha^ and beta^blocking agents: pharmacology and properties PROFESSOR B.N.C. PRICHARD • Adrenergic receptors have been separated into alpha and beta groups, which have then been further subdivided. Agents have been developed that block each type of receptor with varying degrees of specificity between the sub-types, leading to differences in pharmacodynamic profile. A more recent innovation has been the development of multiple action beta-blocking drugs, ie, those not only blocking the beta receptors but also posessing a peripheral vasodilator effect that may be due to alpha blockade, beta-2 stimulation, or a vasodilator action independent of either alpha or beta receptors. • INDEX TERMS: ALPHA BLOCKERS; BETA BLOCKERS; HYPERTENSION • CLEVE CLIN ] MED 1991; 58:33 7-350 HE CONCEPT that binding of Rosenblueth suggested that a transmitter released at catecholamines to receptors leads to differ- sympathetic nerve endings produced either inhibitory ing responses was first described by Langley, or excitatory responses as a result of combination with who in 1905 noted that a cell may make sympathin I or sympathin E at the receptor.3 Tmotor or inhibitory substances or both, and that "the The current classification of alpha and beta respon- effect of a nerve impulse depends upon the proportion ses is based on the classic work of Ahlquist,4 who of the two kinds of receptive substance which is af- studied six sympathomimetic amines and found two fected by the impulse."1 In 1906, Dale reported that patterns of reactivity.

Accepted 8 September, 2011 Arotinolol had been used for treatment of essential hypertension. We conducted a meta-analysis to compare the efficacy and safety of arotinolol with other antihypertensive drugs in treating essential hypertension. Medical databases and review articles were screened with prespecified criteria for randomized controlled trials that reported the effects of and adverse reactions to arotinolol and other antihypertensive drugs in treating essential hypertension. Literature identified meta-analysed using RevMan4.2. Methodology quality of the selected studies was conducted using a Jadad scale. The results were that a total of 176 articles had been found of which 6 were finally included for meta- analysis. The meta-analysis compared the efficacy and safety of arotinolol with other common antihypertensive drugs, including enalapril, felodipine, imidapril, cilinidipine, metroprolol and atenolol. Results indicated that there were no evidence for differences in safety and efficacy.

  • M2021: Pharmacogenetic Testing
    Pharmacogenetic Testing Policy Number: AHS – M2021 – Pharmacogenetic Prior Policy Name and Number, as applicable: Testing • M2021 – Cytochrome P450 Initial Presentation Date: 06/16/2021 Revision Date: N/A I. Policy Description Pharmacogenetics is defined as the study of variability in drug response due to heredity (Nebert, 1999). Cytochrome (CYP) P450 enzymes are a class of enzymes essential in the synthesis and breakdown metabolism of various molecules and chemicals. Found primarily in the liver, these enzymes are also essential for the metabolism of many medications. CYP P450 are essential to produce many biochemical building blocks, such as cholesterol, fatty acids, and bile acids. Additional cytochrome P450 are involved in the metabolism of drugs, carcinogens, and internal substances, such as toxins formed within cells. Mutations in CYP P450 genes can result in the inability to properly metabolize medications and other substances, leading to increased levels of toxic substances in the body. Approximately 58 CYP genes are in humans (Bains, 2013; Tantisira & Weiss, 2019). Thiopurine methyltransferase (TPMT) is an enzyme that methylates azathioprine, mercaptopurine and thioguanine into active thioguanine nucleotide metabolites. Azathioprine and mercaptopurine are used for treatment of nonmalignant immunologic disorders; mercaptopurine is used for treatment of lymphoid malignancies; and thioguanine is used for treatment of myeloid leukemias (Relling et al., 2011). Dihydropyrimidine dehydrogenase (DPD), encoded by the gene DPYD, is a rate-limiting enzyme responsible for fluoropyrimidine catabolism. The fluoropyrimidines (5-fluorouracil and capecitabine) are drugs used in the treatment of solid tumors, such as colorectal, breast, and aerodigestive tract tumors (Amstutz et al., 2018). A variety of cell surface proteins, such as antigen-presenting molecules and other proteins, are encoded by the human leukocyte antigen genes (HLAs).

Koshucharova, R. Zweiker, R. Maier, P. Lercher, V. Stepan, W. Klein, K. Stoschitzky Bisoprolol is a beta1-selective beta-adrenergic antagonist while carvedilol is a non-selective beta-blocker with additional blockade of alpha1-adrenoceptors. Administration of bisoprolol has been shown to cause up-regulation of β-adrenoceptor density and to decrease nocturnal melatonin release, whereas carvedilol lacks these typical effects of beta-blocking drugs. The objective of the present study was to investigate beta-blocking effects of bisoprolol and carvedilol in healthy subjects. We compared the effects of single oral doses of clinically recommended amounts of bisoprolol (2.5, 5 and 10 mg) and carvedilol (25, 50 and 100 mg) to those of placebo in a randomised, double-blind, cross-over study in 12 healthy male volun- teers. Three hours after oral administration of the drugs heart rate and blood pressure were measured at rest, after 10 min. of exercise, and after 15 min.
