Topiramate and Acetazolamide Combination a Comparative Study between High and Low Dose Profile of Side Effects on Metabolism

Abstract

Background: Topiramate, with multiple putative anticonvulsant pathways, is a relatively recent antiepileptic drug. The ability to inhibit carbonic anhydrase, a property common with the acetazolamide anticonvulsant, is among them. Aim: The study refers to compare between the use of combinations of topiramate and acetazolamide high and low doses of drugs and which one is safer for the patients. Methods: Twenty stable adult males wistar rats three weeks after acclimatization and uniformly split into two groups (10 rats in each group) and 60 days of treatment: 9 mg/kg/B.W of Topiramate and 30 mg/kg/B.W of Acetazolamide in the high dose (Hd) group and 5 mg/kg B.W of Topiramate and 30 mg/kg B.W of Acetazolamide in the low dose (Ld) group, orally/day in the high dose (Hd) group. Results: No major differences in mean Glutamate pyruvate transaminase, Glutamic oxaloacetic transaminase, Alkaline phosphatase concentration were found in the statistical analysis of the results in all experimental groups compared with each other at the pretreated period, also revealed that intubation of rats in the 60-days Hd induced a substantial (P>0.05) rise in the mean Glutamate Pyruvate Transaminase and Glutamic Oxaloacetic Transaminase serum concentrations relative to the control and Ld classes. Treatment of low-dose rats showed a substantial (P<0.05) decrease in serum alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen and creatinine enzyme concentrations at 30 and 60 days of the trial compared with the T1 group. Conclusion: The study showed that high-dose combinations of topiramate and acetazolamide had the same adverse effect somewhat in low-dose combinations.
