Revised: 1/2017

1 Indications And Usage 

Ephedrine sulfate injection is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.

2 Dosage And Administration 

Ephedrine sulfate injection is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.

2.1 General Dosage and Administration Instructions

Ephedrine sulfate injection must be diluted before administration to achieve the desired concentration as an intravenous bolus or intravenous infusion. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if the solution is colored or cloudy, or if it contains particulate matter.

2.2 Dosing for the Treatment of Clinically Important Hypotension in the Setting of Anesthesia

The recommended dosage for the treatment of clinically important hypotension in the setting of anesthesia is an initial dose of 5 to 10 mg administered by intravenous bolus. Administer additional boluses as needed, not to exceed a total dosage of 50 mg.

Adjust dosage according to the blood pressure goal (i.e., titrate to effect).

For bolus intravenous administration, prepare a solution containing a final concentration of 5 mg/mL of ephedrine sulfate injection.

  • Withdraw 50 mg (1 mL of 50 mg/mL) of ephedrine sulfate injection and dilute with 9 mL of 5% Dextrose Injection or Sodium Chloride Injection.
  • Withdraw an appropriate dose of the 5 mg/mL solution prior to bolus intravenous administration.

3 Dosage Forms And Strengths 

Ephedrine sulfate injection is available as a single-dose 1 mL vial that contains 50 mg/mL ephedrine sulfate, equivalent to 38 mg ephedrine base.

4 Contraindications 

None

5 Warnings And Precautions 

5.1 Pressor Effect with Concomitant Oxytocic Drugs

Serious postpartum hypertension has been described in patients who received both a vasopressor (i.e., methoxamine, phenylephrine, ephedrine) and an oxytocic (i.e., methylergonovine, ergonovine) [see Drug Interactions (7)]. Some of these patients experienced a stroke. Carefully monitor the blood pressure of individuals who have received both ephedrine and an oxytocic.

5.2 Tolerance and Tachyphylaxis

Data indicate that repeated administration of ephedrine can result in tachyphylaxis. Clinicians treating anesthesia-induced hypotension with ephedrine sulfate injection should be aware of the possibility of tachyphylaxis and should be prepared with an alternative pressor to mitigate unacceptable responsiveness.

5.3 Risk of Hypertension When Used Prophylactically

When used to prevent hypotension, ephedrine has been associated with an increased incidence of hypertension compared with when ephedrine is used to treat hypotension.

6 Adverse Reactions 

The following adverse reactions associated with the use of ephedrine sulfate were identified in the literature. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure.

Gastrointestinal disorders: Nausea, vomiting

Cardiac disorders: Tachycardia, palpitations (thumping heart), reactive hypertension, bradycardia, ventricular ectopics, R-R variability

Nervous system disorders: Dizziness

Psychiatric disorders: Restlessness

8 Use In Specific Populations 

8.1 Pregnancy

Risk Summary

Limited published data on the use of ephedrine sulfate are insufficient to determine a drug associated risk of major birth defects or miscarriage. However, there are clinical considerations [see Clinical Considerations]. Animal reproduction studies have not been conducted with ephedrine sulfate.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Clinical Considerations

Fetal/Neonatal adverse reactions

Cases of potential metabolic acidosis in newborns at delivery with maternal ephedrine exposure have been reported in the literature. These reports describe umbilical artery pH of 7.2 at the time of delivery [see Clinical Pharmacology 12.3]. Monitoring of the newborn for signs and symptoms of metabolic acidosis may be required. Monitoring of infant s acid-base status is warranted to ensure that an episode of acidosis is acute and reversible.

8.2 Lactation

Risk Summary

Limited published literature reports that ephedrine is present in human milk. However, no information is available on the effects of the drug on the breastfed infant or the effects of the drug on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ephedrine sulfate injection and any potential adverse effects on the breastfed child from ephedrine sulfate injection or from the underlying maternal condition.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Clinical studies of ephedrine did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

8.6 Renal Impairment

Ephedrine and its metabolite are excreted in urine. In patients with renal impairment, excretion of ephedrine is likely to be affected with a corresponding increase in elimination half-life, which will lead to slow elimination of ephedrine and consequently prolonged pharmacological effect and potentially adverse reactions. Monitor patients with renal impairment carefully after the initial bolus dose for adverse events.

10 Overdosage 

Overdose of ephedrine can cause a rapid rise in blood pressure. In the case of an overdose, careful monitoring of blood pressure is recommended. If blood pressure continues to rise to an unacceptable level, parenteral antihypertensive agents can be administered at the discretion of the clinician.

11 Description 

Ephedrine sulfate is an alpha- and beta-adrenergic agonist and a norepinephrine-releasing agent. Ephedrine sulfate injection, USP is a clear, colorless, sterile solution for intravenous injection. Each mL contains ephedrine sulfate 50 mg in water for injection as a single-dose product. The pH range is 4.5 to 7.0. The drug product must be diluted before intravenous administration. The chemical name of ephedrine sulfate is (1R,2S)-(-)-2-methylamine-1-phenylpropan-1-ol sulfate (2:1) (salt). Its molecular weight is 428.54.

The structural formula is:

Chemical Structure

image 1

Ephedrine sulfate darkens on exposure to light. It is freely soluble in water and ethanol, very slightly soluble in chloroform, and practically insoluble in ether.

12 Clinical Pharmacology 

12.1 Mechanism of Action

Ephedrine sulfate is a sympathomimetic amine that directly acts as an agonist at - and adrenergic receptors and indirectly causes the release of norepinephrine from sympathetic neurons. Pressor effects by direct alpha- and beta-adrenergic receptor activation are mediated by increases in arterial pressures, cardiac output, and peripheral resistance. Indirect adrenergic stimulation is caused by norepinephrine release from sympathetic nerves.

12.2 Pharmacodynamics

Ephedrine stimulates heart rate and cardiac output and variably increases peripheral resistance; as a result, ephedrine usually increases blood pressure. Stimulation of the -adrenergic receptors of smooth muscle cells in the bladder base may increase the resistance to the outflow of urine. Activation of -adrenergic receptors in the lungs promotes bronchodilation.

The overall cardiovascular effect from ephedrine is the result of a balance among -1 adrenoceptor-mediated vasoconstriction, -2 adrenoceptor-mediated vasoconstriction, and -2 adrenoceptor-mediated vasodilatation. Stimulation of the -1 adrenoceptors results in positive inotrope and chronotrope action.

Tachyphylaxis to the pressor effects of ephedrine may occur with repeated administration [see Warnings and Precautions 5.3].

12.3 Pharmacokinetics

Publications studying pharmacokinetics of oral administration of (-)-ephedrine support that (-) -ephedrine is metabolized into norephedrine. However, the metabolism pathway is unknown. Both the parent drug and the metabolite are excreted in urine. Limited data after IV administration of ephedrine support similar observations of urinary excretion of drug and metabolite. The plasma elimination half-life of ephedrine following oral administration was about 6 hours.

Ephedrine crosses the placental barrier [see Use in Specific Populations 8.1].

13 Nonclinical Toxicology 

13.1 Carcinogenesis and Mutagenesis and Impairment of Fertility

Carcinogenesis: Two-year feeding studies in rats and mice conducted under the National Toxicology Program (NTP) demonstrated no evidence of carcinogenic potential with ephedrine sulfate at doses up to 10 mg/kg/day and 27 mg/kg/day (approximately 2 times and 3 times the maximum human recommended dose on a mg/m2 basis, respectively).

Mutagenesis: Ephedrine sulfate tested negative in the in vitro bacterial reverse mutation assay, the in vitro mouse lymphoma assay, the in vitro sister chromatid exchange, and the in vitro chromosomal aberration assay.

Impairment of Fertility: Studies to evaluate the effect of ephedrine on fertility have not been conducted.

14 Clinical Studies 

The evidence for the efficacy of ephedrine injection is derived from the published literature. Increases in blood pressure following administration of ephedrine were observed in 14 studies, including 9 where ephedrine was used in pregnant women undergoing neuraxial anesthesia during Cesarean delivery, 1 study in non-obstetric surgery under neuraxial anesthesia, and 4 studies in patients undergoing surgery under general anesthesia. Ephedrine has been shown to raise systolic and mean blood pressure when administered as a bolus dose following the development of hypotension during anesthesia.

Ephedrine Sulfate Injection Usp, 50 Mg/ml  

Forr IM, IV or SC Use

Rx only

Description  

Ephedrine Sulfate Injection, USP is a sterile solutionn of 50 mg ephedrine sulfate in Water for Injection.

Ephedrine ooccurs as fine, white, oodorless crystals or powder and darkens on exposure to light. It is freely soluble in water and sparingly soluble in alcohol.

The chemical name of ephedrine sulfate is (C10H15NO)2 H2SO4 benzenemethanol -[l - (methylamino) ethyl] - sufate (2:1) (salt). Its molecular weight is 428 .54. The structural formula is:

Structural Formula

Clinical Pharmacology  

Ephedrine sulfate is a potent sympathomimetic that stimulates both and receptors and has clinical uses related to both actions. Its peripheral actions, which it owes in part to the release of norepinephrine, simulate responses that are obtained when adrenegenic nerves are stimulated. These include an increase in blood pressure, stimulation of heart muscle, constriction of arterioles, relaxation of the smooth muscle of the bronchi and gastrointestinal tract, and dilation of the pupils. In the bladder, relaxation of the detrusor muscle is not prominent, but the tone of the trigone and vesicle sphincter is increased.

Ephedrine sulfate also has a potent effect on the CNS. It stimulates the cerebral cortex and sub-cortical centers, which accounts for its use in narcolepsy.

The cardiovascular responses reported in man include moderate tachycardia, unchanged or augmened stroke volume, enhanced cardiac output, variable alterations in peripheral resistance and usually a rise in blood pressure. The action of ephedrine is more prominent on the heart than on the blood vessels. Ephedrine sulfate increases the flow of coronary, cerebral and muscle blood.

In patients with myasthenia gravis, administration of Ephedrine Sulfate Injection, USP produces a real but modest increase in motor power. The exact mechanism by which ephedrine sulfate affects skeletal muscle contractions is unknown.

Indications And Usage  

Ephedrine Sulfate Injectionn, USP is indicated in the treatment of allergic disorders, such as bronchial asthma The drug has long been used as a pressor agent, particularly during spinal anesthesia when hypotensionn frequently ooccurs. In Stokes-Adams syndromeme with complete heart block, ephedrine has a value similar to that of epinephrine. It is indicated as a central nervous system stimulant in narcolepsy and depressive states. It is also used in myasthenia gravis.

Contraindications  

Allergic reactions to ephedrine sulfate are rare. The hypersensitivity, if known, is a specific contraindication. Patients hypersensitive to other sympathomimetics may also be hypersensitive to ephedrine sulfate.

Precautions  

GENERAL - Special care should be used when administering Ephedrine Sulfate Injection, USP to patients with heart disease, angina pectoris, diabetes, hyperthyroidism, prostatic hypertrophy or hypertension and to patients receiving digitalis. Prolonged use may produce a syndrome resembling an anxiety state. Tolerance to ephedrine sulfate may develop, but temporary discontinuance to the drug restores its original effectiveness.

DRUG INTERACTIONS - Concurrent use of ephedrine sulfate with general anesthetics, especially cyclopropane or halogenated hydrocarbons or digitalis glycosides may cause cardiac arrhythmias, since these medications may sensitize the myocardium to the effects of ephedrine sulfate.

Therapeutic doses of ephedrine sulfate can inhibit the hypotensive effect of guanethidine, bethanidine, and debrisoquin by displacing the adrenergic blockers from their site of action in the sympathetic neurons.
