4.4 Special Warnings And Precautions For Use



Potassium Citrate Mixture provides symptomatic relief only and is not anti-bacterial. Effective anti-bacterial therapy should be co-prescribed. It should be used with caution when renal or cardiac dysfunction is present.



Labels to state: if symptoms persist consult your doctor.



Discard any unused mixture 2 months after opening.



Use with caution in the elderly.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Concurrent administration of potassium-containing drugs, potassium sparing diuretics or other drugs that increase potassium levels (e.g. ACE inhibitors, ciclosporin, aliskiren) may lead to hyperkalaemia. May interact with cardiac glycosides. Citrates alkalinise the urine and thus may alter the urinary excretion of a number of drugs. This may lead to increased renal clearance of acidic drugs, such as salicylates, tetracylines and barbiturates, and prolongation of the half-life of basic drugs, such as sympathomimetics and stimulants. Particularly noteworthy is the diminished anti-bacterial activity of nitrofurantoin and methenamine.



4.6 Pregnancy And Lactation



No adverse effects are anticipated at recommended doses when used for initial symptomatic relief only. Treatment with potassium citrate mixture is adjunctive and secondary to anti-bacterial treatment of urinary tract infection.



4.7 Effects On Ability To Drive And Use Machines



No effect on mental alertness.



4.8 Undesirable Effects



Mild nausea and occasionally vomiting may occur due to gastric irritation. Other side effects are those due to hyperkalaemia (if this occurs).



4.9 Overdose



Overdosage is accompanied by nausea, vomiting, abdominal pain and symptoms due to hyperkalaemia and metabolic acidosis. Fluid and electrolyte balance together with ECG should be closely monitored.



Treatment is symptomatic and supportive. Moderate to severe hyperkalaemia is a medical emergency requiring prompt correction.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Citrate and citric acid solutions are systematic and urinary alkalinizers thereby providing symptomatic relief of dysuria.



5.2 Pharmacokinetic Properties



Potassium Citrate is absorbed and the citrate is metabolised to bicarbonate. Citric acid is metabolised to carbon dioxide and water. Oxidation is virtually complete with less than 5% of citrate being excreted unchanged in the urine.



5.3 Preclinical Safety Data



None.
