VELARDE, Jeaneth et al. WATER FILTER IN THE PREPARATION OF CHEMOTHERAPY TO OPTIMIZE BIOSAFETY. Rev. Méd. La Paz [online]. 2016, vol.22, n.2, pp. 12-17. ISSN 1726-8958.

Chemotherapeutic drugs are made at a barometric pressure corresponding to a sea level. In cities ofhigh altitude such as La Paz (3600 m.a.s.l.), the pressure inside the drug bottle is higher and this represents a risk of leakage from drug. Objective Describe the usefulness of distilled water as water filter in the preparation of chemotherapy to avoid severe adverse events in health staffand the environment. Material and methods Chemotherapeutic drugs such as methotrexate, adriamycin and endoxan were tested. The volume of air expelledfrom inside the bottle to the syringe was measured. It was evaluated the utility of using 5 ml of distilled water in 20-mL syringes as water filter. By means of a spectral scanning it was obtained the wavelengths of maximum absorption from the chemotherapeutics. The concentration of each chemotherapeutic drug inside water filters were determined by using a Shimadzu UV1800 spectrophotometer. Results Air volumes were differentin each chemotherapeutic drug, volume varied according to manufacturing brand. Water filters reading showed a concentration of Adriamycin 33.8 ug/ml for Filaxis brand and 32.8 ug/ml for LKM, Methotrexate LKM showed 7.6 ug/ml, and cyclophosphamide 16.6 ug/ ml for LKM and 14.0 ug/ml for Baxter. Conclusion The water-soluble property of chemotherapeutic drugs allows a feasible use of distilled water as water filter which retains cytostatics in an unknown but significant percentage. The use of distilled water as water filter is a significant tool to optimize biosafety.
