Chỉ số theo dõi
Closely monitor serum K levels (particularly in hypoxic patients); signs and symptoms of shock or anaphylactoid reactions.
Quá liều
Oral: Symptoms: Tachycardiac arrhythmia, hypotension, tremor, nervousness, hypokalaemia, hyperglycaemia. Management: Perform gastric lavage, if necessary. Provide emergency treatment and general maintenance therapy, if necessary. In case of serious tachycardiac arrhythmia, careful administration of β-blockers (e.g. propranolol) may be considered.
Tương tác
May result in aggravated decrease in serum K levels and cardiac adverse effects with corticosteroids (e.g. betamethasone, hydrocortisone), xanthine derivatives (e.g. theophylline), and diuretics (e.g. furosemide). Potentially Fatal: Catecholamines (e.g. epinephrine, isoprenaline) potentiate the adrenoceptor stimulating effects of procaterol, which may lead to arrhythmias or cardiac arrest.
