NAME OF THE MEDICINAL PRODUCT
Sodium Bicarbonate Infusion BP 4.2% Polyfusor BE
QUALITATIVE AND QUANTITATIVE COMPOSITION
Polyfusor BE has the following composition: Name Sodium Bicarbonate Specification Reference EP 4.2
Therapeutic indications For the treatment of metabolic acidosis and rapid urine alkalinisation
Posology and method of administration Adults and Children The volume, strength and rate of infusion will depend upon the requirements of the individual patients as perceived by the physician. Administration should be effected cautiously and gradually. In the less urgent forms of metabolic acidosis, an average dose for adults and older children is 2 - 5 ml of bicarbonate per Kg bodyweight, given over 4 - 8 hours. Subsequent doses of sodium bicarbonate should be adjusted to the individual patients requirements. It is generally recommended that administration should be initiated with half the calculated dose, which may be adjusted subject to satisfactory blood gas analysis Elderly Care should be taken to avoid circulatory overload, particularly in, patients with cardiac and renal insufficiency. For intravenous infusion.
Contraindications Intravenous infusions of sodium bicarbonate may be contraindicated in, patients with hypertension, impaired renal and cardiac function, pulmonary oedema, respiratory and metabolic alkalosis, hyperventilation, hypernatraemia and eclampsia.
Special warnings and precautions for use Infusion of sodium bicarbonate solutions must be strictly intravenous, since extravasation may lead to tissue necrosis. Administration to patients receiving cardio-pulmonary resuscitation may induce pulmonary oedema. Careful attention should be given to avoid possible hypokalaemia. The label states: Do not use unless solution is clear and free from particles.
Interaction with other medicinal products and other forms of interaction Sodium bicarbonate will alkalinise the urine and reduce the urinary excretion of amphetamines, methadone, quinidine and quinine. Sodium bicarbonate will reduce the effectiveness of hexamine compounds, which are only effective as urinary antiseptics in acid urine. The renal excretion of lithium appears to be increased by sodium bicarbonate and this could lead to reduced plasma levels of lithium and impairment of the therapeutic response.
Pregnancy and lactation The safety of sodium bicarbonate infusion during pregnancy and lactation has not been assessed, but its use during these periods is not considered to constitute a hazard.
Effects on ability to drive and use machines Not applicable.
Undesirable effects Thrombosis of the chosen vein is always a possibility with intravenous infusion
Overdose Overdoses may cause hyperpnoea, nausea and convulsions. Particular care should be paid to administration in the elderly and infants. Over-rapid infusion may lead to hyperosmolarity. In cases of overdosage the infusion of sodium bicarbonate should be discontinued immediately and metabolic alkalosis corrected by means of administration of 0.9% w/v sodium chloride intravenous infusion BP.
Pharmacodynamic properties Sodium bicarbonate provides a source of bicarbonate ions, which will neutralise the relative excess of hydrogen ions present in acidotic conditions.
Pharmacokinetic properties No data available Preclinical safety data None Stated
