Abstract
This research work investigated and compared the chronic renal toxicological profile of disulfiram,
copper gluconate and disulfiram/copper gluconate combination, in a 90-day time- and dose-de-
pendent study in rodents. 88 rats weighing an average of 280 g divided into eleven groups con-
sisting of 8 rats each were used for this experiment. The control groups received normal saline as
placebo and 99.5% dimethyl sulfoxide (DMSO) (solvent control). Three oral doses (low, medium
and high) of disulfiram (18.65 mg/kg, 37.3 mg/kg and 74.6 mg/kg), copper gluconate (3.75 mg/kg,
7.5 mg/kg and 15 mg/kg) and both drugs in combination were administered daily with those of
the combination given 12 hours apart. Blood samples were collected via cardiac puncture in
heparinised bottles and centrifuged, and the serum was decanted on 30, 45, 60 and 90 days for
analysis. Renal function parameters—electrolytes (Na
+
, K
+
), urea and creatinine were evaluated.
Results showed significant (p < 0.05) dose- and time-dependent increase in electrolyte level (Na
+
,
K
+
), blood urea and creatinine respectively. The results are all pointers to the development of re-
nal failure. It therefore appears that the DSF/CG combination is nephrotoxic and this effect is
dose-dependent and synergistic.
