Web20. jan 2024 · Phenylephrine is metabolized in the liver and gastrointestinal tract and has duration of action of 20 minutes. It may be used to manage severe hypotension, but for the failing heart the undesirable increase in afterload and oxygen consumption mitigate any benefits of beta-1 stimulation. Indications and contraindications Inotropes Dopamine WebThere was no difference in the need to give glycopyrrolate for bradycardia ( table 3 ). One phenylephrine group, no ephe-drine group and one combination group patient received glycopyrrolate for a heart rate less than 45 beats/min.
