Racepinefrine (INN Tooltip International Nonproprietary Name, USAN Tooltip United States Adopted Name), or racepinephrine, sold under the brand name Vaponefrin among others, is a sympathomimetic medication described as a vasoconstrictor, bronchodilator, cardiostimulant, mydriatic, and antiglaucoma agent.
Epinephrine, also known as adrenaline, is a medication and hormone. [10] [11] As a medication, it is used to treat several conditions, including anaphylaxis, cardiac arrest, asthma, and superficial bleeding. [8] Inhaled epinephrine may be used to improve the symptoms of croup. [12] It may also be used for asthma when other treatments are not ...
Guidelines for treating resistant hypertension have been published in the UK [45] and US. [46] It has been proposed that a proportion of resistant hypertension may be the result of chronic high activity of the autonomic nervous system, known as "neurogenic hypertension". [47] Low adherence to treatment is an important cause of resistant ...
In general, pure beta-adrenergic agonists have the opposite function of beta blockers: beta-adrenoreceptor agonist ligands mimic the actions of both epinephrine- and norepinephrine- signaling, in the heart and lungs, and in smooth muscle tissue; epinephrine expresses the higher affinity.
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) antagonists and alpha-2 (α 2) agonists, which are used to treat high ...
Most chapters within a unit are organized as follows, although there are some exceptions. Nursing-sensitive patient outcomes (NOC) are discussed before interventions. This is because in the sequence of clinical reasoning desired outcomes are identified prior to selection of interventions to achieve the outcomes.
Guidelines on the choice of agents and how best to step up treatment for various subgroups in hypertension (high blood pressure) have changed over time and differ between countries. A Comparison of International Guidelines on Goal Blood Pressure and Initial Therapy for Adults With Hypertension (adapted from JNC 8 guidelines [ 1 ] )
Dobutamine is administered as a racemic mixture consisting of both (+) and (−) isomers; the (+) isomer is a potent β 1 agonist and α 1 antagonist, while the (−) isomer is an α 1 agonist. [9] The administration of the racemate results in the overall β 1 agonism responsible for its activity.
