[Detection of nephrotoxics and dose adjustment in patients with low glomerular filtration rate in community pharmacy: methodology].

ABSTRACT

Chronic kidney disease is a prevalent problem without specific treatment. Early detection is important and estimated glomerular filtration rate (eGFR) is a very affordable test that can be performed in community pharmacies. If present, it is very important not to further damage the kidney by avoiding the use of nephrotoxic drugs and adjusting the doses of other renal elimination drugs and the community pharmacy is very well positioned to do this.

OBJECTIVE

To describe the methodology used to detect nephrotoxic drugs and adjust doses of other drugs in community pharmacies for subsequent referral to primary care.

METHOD

Multicentre experimental multicentre uncontrolled follow-up study carried out in community pharmacies in 4 autonomous communities in Spain. Patients who met the inclusion criteria and signed the informed consent form were included. Those with eGFR <60 ml/min/1.73m were studied and their medication was analysed using the BOT Plus and 4 other sources of information.

RESULT

670 patients were included, 215 of them with eGFR<60ml/min/1.73m. Of these 90 (41.9%) needed some type of adjustment in the pharmacist's judgement. Of these 90, 43.3% (39) had some kind of change after the pharmacist's intervention.

CONCLUSION

In patients with low glomerular filtration rate, with the appropriate methodology, the community pharmacist is able to detect the use of nephrotoxic drugs or the use of drugs at doses higher than those recommended according to their renal status.
