Metaraminol bitartrate is a potent sympathomimetic amine that increases both systolic and diastolic blood pressure.
ARAMINE is indicated for prevention and treatment of the acute hypotensive state occurring with spinal anesthesia. It is also indicated as adjunctive treatment of hypotension due to hemorrhage, reactions to medications, surgical complications, and shock associated with brain damage due to trauma or tumor.

Published Studies Related to Aramine (Metaraminol)
The effect of prophylactic metaraminol on systemic hypotension caused by induction of anaesthesia with propofol in patients over 55 years old. [2001.09]
We conducted a double-blind, randomised, placebo-controlled study evaluating the efficacy of prophylactic metaraminol for preventing propofol-induced hypotension. Thirty patients aged 55-75 years undergoing general anaesthesia were randomly allocated to receive either metaraminol 0.5 mg or saline before administration of fentanyl 1 microg.kg(-1) and propofol 2 mg.kg(-1)...
Metaraminol infusion for maintenance of arterial blood pressure during spinal anesthesia for cesarean delivery: the effect of a crystalloid bolus. [2001.09]
We randomly allocated women having elective cesarean delivery to receive either no bolus (Control Group, n = 31) or 20 mL/kg lactated Ringer's solution (Bolus Group, n = 35) IV before spinal anesthesia. An infusion of metaraminol started at 0.25 mg/min was titrated to maintain systolic arterial blood pressure in the target range 90%-100% of baseline...
Comparison of metaraminol and ephedrine infusions for maintaining arterial pressure during spinal anesthesia for elective cesarean section. [2001.08]
BACKGROUND: Although ephedrine is usually recommended as the first-line vasopressor in obstetrics, its superiority over other vasopressors has not been proven in humans... CONCLUSIONS: When used by infusion to maintain arterial pressure during spinal anesthesia for cesarean section, metaraminol was associated with less neonatal acidosis and more closely controlled titration of arterial pressure compared with ephedrine.
A comparative study of three different methods of administering metaraminol during spinal anaesthesia in the elderly. [2001.04]
We compared three methods of administering metaraminol during spinal (subarachnoid) anaesthesia. Fifty-two elderly patients with fractured hips were studied...
Hypotension during subarachnoid anaesthesia: haemodynamic effects of colloid and metaraminol. [1996.05]
We have studied 45 patients, aged 60-95 yr, receiving subarachnoid block for neck of femur fractures. Patient received either colloid (polygeline, Haemaccel) 8 ml kg-1 (n = 15), metaraminol 5 micrograms kg-1 and 1.7 micrograms kg-1 min-1 (n = 15) or a combination of both treatments to maintain systolic arterial pressure (SAP) between 75 and 100% of baseline...

Up-Down Determination of the ED90 of Metaraminol to Treat Hypotension During Cesarean Section [Completed]
Ephedrine, Phenylephrine and Metaraminol Effects on Maternal Cardiac Output, Uterine Blood Flow and Fetal Circulation [Active, not recruiting]
It is a prospective clinical trial with random distribution that intends to investigate
maternal and fetal effects of ephedrine, phenylephrine and metaraminol during cesarean
delivery in patients with pre-eclampsia.
Maternal and Neonatal Outcomes of the Use of Vasopressors to Treat Hypotension During Spinal Anesthesia for Cesarean [Recruiting]
Anesthesia for cesarean section has been a great challenge for the anesthesiologist, for
mother and fetus are closely related. So the challenge is to anesthetize the mother without
interfering with the physiology of the fetus. The spinal block, although safe, are not free
of complications if not treated properly, may be responsible for increased fetal morbidity.
Among the major side effects, there is hypotension, with potentially serious consequences
for the maternal-fetal dyad. Hypotension in pregnant women at low risk may not lead to major
damage, but a pregnant woman with low reserves, as is the case of pregnant women with
pre-eclampsia, any drop in blood pressure of the mother can bring harm to the welfare of
mother and fetus. Based on the above, the purpose of this study is to compare the effects of
maternal and perinatal treatment of hypotension with ephedrine or metaraminol in pregnant
women with severe preeclampsia undergoing cesarean section under spinal anesthesia. There
will be a randomized, double-blind, which will be included pregnant women with severe
preeclampsia with indication of cesarean section, gestational age above 34 weeks gestation
and only. Will be Excluded women with hemorrhagic syndromes of pregnancy, HELLP syndrome,
eclampsia, cardiovascular or cerebrovascular disease, fetal distress and absolute
contraindications to spinal anesthesia.
All patients are fully informed of the research objectives and will only be included in the
study if they agree to participate and sign the Instrument of Consent. The project was
designed following the recommendations of Resolution 196/96 of the National Health and the
Declaration of Helsinki for research involving human subjects (2000). In addition, the
project was submitted to the Ethics Committee in Research of the Institute of Integrative
Medicine Professor Fernando Figueira, is approved. The study will be conducted from June
2011 to July 2012. The study variables are: consumption of metaraminol and ephedrine before
and after birth, the occurrence of nausea and vomiting, incidence of maternal hypotension,
the occurrence of reactive hypertension, occurrence of bradycardia, pH of umbilical cord,
Apgar score 5 minutes, need for face mask ventilation and ICU admission.
Prophylaxis Ephedrine or Ondansetron Prevents Hypotension After Spinal Anesthesia for Cesarean Section [Completed]
Maternal hypotension after spinal anesthesia in parturients undergoing cesarean section is a
very common problem leading to several complications to both patients and their babies. It
can cause maternal discomfort, lightheadedness, nausea and vomiting. The most important
complication is the decreasing blood flow to babies; which may lead to fetal acidosis.
Many interventions has been studied in order to prevent hypotension after spinal anesthesia
in cesarean section e. g., fluid loading: colloid vs crystalloid, medications: ephedrine,
phenylephrine, and metaraminol, etc. The recent study showed ondansetron (the antiemetic
drug) can be effectively used to prevent hypotension after spinal anesthesia in normal
patients or parturients. The action of ondansetron is believed to inhibit Bezold-Jarish
This aim of this study is to compare the efficacy of ephedrine and ondansetron in the
prevention of maternal hypotension after spinal anesthesia in cesarean section.
