Laboratorieundersøgelser viste forbigående kalciumniveauer under den normale referenceværdi (mindre end 2, 10 mmol/ l) hos 2, 3% af de Aclasta- behandlede patienter i et større klinisk studie sammenlignet med 21% af Aclasta- behandlede patienter i de kliniske forsøg med Pagets sygdom.
Based on laboratory assessment, transient asymptomatic calcium levels below the normal reference range (less than 2.10 mmol/ l) occurred in 2.3% of Aclasta-treated patients in a large clinical trial compared to 21% of Aclasta-treated patients in the Paget’ s disease trials.
