| Resumo: |
The aim of this work was to study the effect of antimalarial drugs on the bioavailability of 99mTc-MDP in rats. Mefloquine (MQ) and artemisinin (AM) were administered in two treated groups (T) and sorbitol in control group (C) for 7 days. Then, 99mTc-MDP was injected in all groups and %ATI was calculated. A significant increase of %ATI in MQ group, from C to T, occurred in spleen (0.35±0.10to0.58±0.13), liver (1.69±0.28to3.31±0.07) and blood (0.79±0.17to2.09±0.53). The %ATI increased significantly in AM group:femur (2.76±0.59to5.98±0.70), liver (1.69±0.28to4.59±0.68), lungs (0.29±0.05to6.22±0.86), spleen (0.35±0.10 to0.86±0.15) and blood (0.79±0.17 to4.65 ±0.74). A significant decrease of %ATI occurred in MQ group:bladder (0.75±0.07to0.26±0.05), stout bowel (2.13±0.34to0.66±0.19), pancreas (0.87±0.24to0.28±0.18), kidneys (7.00±1.52to3.46±0.62), brain (0.27±0.08to 0.05±0.01) and also in AM group:bladder (0.75±0.07to0.30±0.05), stout bowel (2.13±0.34to0.36±0.08), muscle (2.04±0.39to0.26±0.06), pancreas (0.87±0.24to0.46±0.12) and kidneys (7.00±1.52to4.35±0.28). These results could be associated to biological effects of antimalarial drugs.
