Chiral determination of various adrenergic drugs by thin-layer chromatography using molecularly imprinted chiral stationary phases prepared with α-agonists

The Analyst, 1999
Thin-layer chromatography (TLC) based on molecularly imprinted polymers (MIPs) of alpha-agonists as chiral stationary phases was applied to the determination of enantiomers of various adrenergic drugs including alpha- and beta-agonists and beta-antagonists (beta-blockers). In this study, three MIPs imprinted with (+)-ephedrine, (+)-pseudoephedrine and (

Catecholamines in cardiac arrest: role of alpha agonists, beta-adrenergic blockers and high-dose epinephrine

Resuscitation, 2000
Once initial defibrillation has failed, the advanced cardiac life support (ACLS) guidelines for cardiopulmonary resuscitation (CPR) recommend periodic intravenous administration of epinephrine to increase coronary artery perfusion pressure (CPP) via arterial vasoconstriction to [1].

Cocaine facilitates the effects of α-agonists and antagonists on adrenergic neurotransmission

General Pharmacology: The Vascular System, 1981
Abstract 1. 1. The facilitatory effect of phentolamine on adrenergic neurotransmission was enhanced by cocaine 2.9 μM in both the cat nictitating membrane and the perfused cat spleen. Cocaine alone did not significantly increase 3H-overflow by nerve stimulation. 2. 2.

Resistant Hypertension in the Elderly-Second Line Treatments: Aldosterone Antagonists, Central Alpha-Agonist Agents, Alpha-Adrenergic Receptor Blockers, Direct Vasodilators, and Exogenous Nitric Oxide Donors

Cardiovascular & Hematological Agents in Medicinal Chemistry, 2015
Resistant hypertension (RH) is a prevalent medical problem across all ages but is more frequent in elderly patients. This entity has to be distinguished from clinical settings which may simulate it such as apparent hypertension (pseudohypertension) or apparently resistant hypertension (pseudoresistant hypertension) [1].

Potentiative effects of alpha agonistic sympathomimetic amines on vasoconstriction by adrenergic nerve stimulation.

The Journal of Pharmacology and Experimental Therapeutics, 1980
The effects of catecholamines and other sympathomimetic amines with alpha adrenergic activity on vasoconstriction were studied. Short ring segments were prepared from five rabbit blood vessels including the mesoduodenal, brachial, central ear and pulmonary lobar arteries and the saphenous vein.

[Regularities of the alpha-agonists inhibitory effect on the magnitude of maximum adrenergic response of the rat vas deferens].

Fiziologicheskii zhurnal SSSR imeni I. M. Sechenova, 1989
The inhibitory effect of alpha-agonists noradrenaline and phenylephrine on the maximal alpha 1-adrenergic contractile response was studied in the rat isolated vas deferens and its epididymal and prostatic sections. The degree of noradrenaline (2.10(-5) M) inhibition of the maximal response was directly related to the magnitude of response to ...
