Ischaemic heart diseaseHypertensionThyrotoxicosisProstatic hypertrophyEphedrine has positive inotropic and chronotropic effects on the heart and its use should be avoided in patients with ischaemic heart disease.Ephedrine increases blood pressure in man. Over the counter acquisition of sympathomimetics should always be considered in hypertensive patients whose blood pressure control has suddenly deteriorated.Patients with hyperthyroidism may be susceptible to the effects of ephedrine. Ephedrine may precipitate acute urinary retention in patients with prostatic hypertrophy.
4.4 Special warnings and precautions for use
Ephedrine should be given with care to patients with hyperthyroidism, diabetes mellitus, angle-closure glaucoma and renal impairment. Ephedrine has potentially life threatening effects in its acute cardiovascular and central stimulant effects.Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
4.5 Interaction with other medicinal products and other forms of interaction
Other adrenoceptor stimulants: Concurrent use of ephedrine with theophylline may result in increased nausea, nervousness, and insomnia.Anaesthetics: There may be an increased risk of arrhythmias when used with volatile liquid anaesthetics.Antidepressants: Ephedrine should not be given to patients who are being treated with monoamine oxidase inhibitors as they may cause hypertensive crisis with marked headache, severe hypertension and subarachnoid haemorrhage. Noradrenaline is displaced by ephedrine with the release of large amounts of catecholamine. The interaction may occur up to two weeks after stopping MAOI therapy. There may be an increased risk of arrhythmias when ephedrine is used with tricyclic antidepressants.Antihypertensives: Loss of blood pressure control has been detected in hypertensive patients undergoing concurrent therapy with ephedrine and adrenergic neurone blocking drugs and may also occur with other antihypertensives.Antimigraine drugs: Enhanced vasoconstriction and pressor effects with ergotamine or methysergide; concurrent use of ergotamine not recommended (risk of gangrene).Cardiac glycosides: Increased risk of arrhythmias in patients receiving ephedrine and cardiac glycosides.Corticosteroids: Ephedrine has been shown to increase the clearance and prolong the half-life of dexamethasone in asthmatic patients.Oxytocin: Increased risk of vasoconstrictor or pressor effects in patients receiving oxytocin and ephedrine.Urinary acidifiers/alkalinisers: Effects of ephedrine may be reduced by acidification and increased by alkalinization of the urine.
4.6 Pregnancy and lactation
The use of ephedrine in pregnancy should be avoided as ephedrine crossed the placenta and this has been associated with an increase in foetal heart rate and beat to beat variability. Ephedrine is excreted in breast milk and therefore its use during lactation should be avoided. Irritability and disturbed sleep patterns have been reported in breast fed infants.
4.7 Effects on ability to drive and use machines
4.8 Undesirable effects
The most common side-effects of ephedrine are tachycardia, anxiety,nausea, restlessness and insomnia. Tremor, dry mouth, impaired circulation to the extremities, hypertension, headache and cardiac arrhythmias may occur. Tolerance with dependence has been reported with prolonged administration.Myocardial infarction has occurred very rarely in patients taking ephedrine or pseudoephedrine.Ephedrine may act as stimulant in children with nocturnal enuresis and cause sleeplessness. It may have sedative effects in some children.The elderly are more sensitive to the cardiovascular effects of ephedrine.
a) SymptomsThe symptoms of overdose are normally seen as nausea, vomiting, hypertension, fever, palpitations, tachycardia, restlessness, respiratory depression and convulsions. Paranoid psychosis, delusions and hallucinations may also follow ephedrine overdosage.b) TreatmentIn severe overdosage, the stomach should be emptied by emesis and lavage. Management is by supportive symptomatic therapy.
5. Pharmacological properties
5.1 Pharmacodynamic properties
Ephedrine is a sympathomimetic agent with direct and indirect effects on adrenergic receptors.When given by mouth in therapeutic doses, ephedrine constricts the peripheral vessels, thus increasing blood pressure. It also relaxes bronchioles.
5.2 Pharmacokinetic properties
Ephedrine is rapidly and completely absorbed after oral administration and extensively distributed throughout the body with accumulation in the liver, lungs, kidneys, spleen and brain.Peak plasma concentrations are attained during therapy of 65-120 ug/ml, effective bronchodilator plasma levels are in the range 35-80 ug/ml.The plasma half-life is reported to be between 3-11 hours, with up to 95% being excreted in the urine.
5.3 Preclinical safety data
Studies in mice have shown that the lethal toxicity of ephedrine is increased by elevation of body temperature.Ephedrine induces acute locomotor stimulatory activity in rats and mice. The estimated lethal dose in children up to 2 years of age is 200mg and for adults 2g. Fatalities are rare and single doses up to 400mg have been given without serious toxic effects.
