Background:
The effects of chronic valproic acid administration on bone health have been a matter of concern and controversy. In this study, the bone status following valproate intake was assessed by using several bone-related biochemical markers.
Materials And Methods:
In this case-control study, 62 epileptic patients and 40 age- and gender-matched controls were enrolled. The patients had been under chronic valproate therapy (758 ± 29 mg/day) for at least the past 6 months, without any vitamin D/or calcium supplementation. Serum markers of bone turnover (carboxy-terminal telopeptide of type I collagen (CTX) and bone-specific alkaline phosphatase [BALP]), calcium, phosphorus, total alkaline phosphatase, and parathyroid hormone levels were measured in both groups.
Results:
The markers of bone turnover as well as other measured bone biochemical parameters did not statistically differ between the two groups.
Conclusion:
Valproate therapy at the mentioned doses does not seem to change bone turnover in adult epileptic patients.

Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
