Changes in serum triglyceride and cholesterol levels during long-term phenytoin treatment for epilepsy. 1979

P V Luoma, and M I Reunanen, and E A Sotaniemi

The effect of long-term phenytoin therapy on serum triglyceride and cholesterol levels in 20 patients with epilepsy was investigated. In patients followed up for six years, phenytoin treatment was associated with an increase in serum triglyceride and cholesterol levels. The most significant increases in lipid levels were measured during the first months of therapy, whereafter values generally tended to decrease. The elevation in serum triglyceride concentration was relatively greater than that in serum cholesterol level. Cholesterol concentrations, however, remained high for a longer period. The results demonstrate that phenytoin therapy for epilepsy is associated with a rise in serum triglyceride and cholesterol levels, the degree of which seems to be related to the duration of the treatment. The changes presumably reflect phenytoin effects on hepatic lipid metabolism.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010672 Phenytoin An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.

D004827 Epilepsy A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).
