Aligns with standardization recommendations of patient safety and professional organizations.35

Biorphen is Clinically Effective1

  • The onset of blood pressure increase following an intravenous bolus phenylephrine hydrochloride administration is rapid, typically within minutes1
  • Phenylephrine is recommended as a first-line vasopressor during cesarean section under spinal anesthesia due to extensive supporting data6*
  • Phenylephrine is an acceptable vasopressor for septic shock in the case of norepinephrine-associated arrhythmias or in salvage therapy7**

*α-agonist drugs are the most appropriate agents to treat or prevent hypotension following spinal anaesthesia. Although those with a small amount of β-agonist activity may have the best profile, phenylephrine is recommended due to
the amount of supporting data.6

**Phenylephrine is not recommended in the treatment of septic shock except in circumstances where (a) norepinephrine is associated with serious arrhythmias, (b) cardiac output is known to be high and blood pressure persistently low or (c) as salvage therapy when combined inotrope/vasopressor drugs and low-dose vasopressin have failed to achieve MAP target (grade 1C).7

Did you know? Push-Dose Pressors in the Emergency Department

Bolus administration of phenylephrine, or “push-dose pressors,” are reportedly widely used in the Emergency Department (ED) for transient hypotension, or until central access can be obtained to initiate a continuous infusion of vasopressors8-10. Authors note that phenylephrine in the ED is usually manually compounded “on demand” at the patient’s bedside for immediate use.9, 10
