Introduction: Several studies have reported that commonly used antiepileptic drugs like phenytoin, and carbamazepine increase serum High Density Lipoproteins Cholesterol (HDL-C) levels, while some others documented no such effect. Further, some researchers also observed that valproic acid and other newer antiepileptic drugs like lamotrigine and levetiracetam has no influence on serum lipid profile. The present study was planned to assess and compare serum lipid profile of young adult patients on commonly used antiepileptic drugs (phenytoin, oxcarbazepine and valproic acid) and newer antiepileptic drug (levetiracetam) attending Neurology OPD of a tertiary care hospital in Puducherry, India compared to normal subjects.
Materials and Methods: A prospective hospital based cross-sectional study was conducted in Tertiary care hospital. Epileptic patients attending Department of Neurology and taking antiepileptic drugs for last six months or more and on regular follow up; approximately 60 patients on commonly used antiepileptic drugs (20 on phenytoin, 20 on oxcarbazepine, 20 on valproic Acid) and 20 patients on newer antiepileptic drug (levetiracetam) was included in the study. Age and sex matching 80 controls were taken.
Statistical analysis: Descriptive statistics explained using mean ± SD. Inferential statistics was used depending on the nature of variables. We used one-way-ANOVA and followed by independent t-test for comparison with control group and statistically significant was considered at p-value <0.05. Results: We observed statistically significant high mean TC, HDL-C, LDL-C and TG levels in the group receiving phenytoin for more than six months when compared with control group. We observed statistically significant high mean TC, HDL-C and TG levels in the group receiving oxcarbazepine for more than six months when compared with control. However, no significant difference was observed in mean LDL-C levels when compared to control. We did not observe any statistically significant difference among mean TC, HDL-C, LDL-C and TG levels in the group receiving valproate. We did not observe any statistically significant difference among mean TC, HDL-C, LDL-C and TG levels in the group receiving levetiracetam.
Conclusion: From the present study we can conclude that CYP enzyme inducer anti epileptic medicines like phenytoin and oxcarbazepine is strongly associated with increased levels of TC, LDL-C, HDL-C and TG where as valproate and levetiracetam showed no significant change. Therefore, the serum cholesterol level should be regularly monitored in patients undergoing therapy with inducer anti epileptic medicines.
