Topiramate-induced Weight Loss: A Review


Topiramate-induced Weight Loss: A Review

Alberto Verrotti et al. Epilepsy Res. .


Background: Weight loss can occur during topiramate (TPM) treatment and it should be evaluated by clinicians, especially in children, whose growth could be compromised. In international literature, the reported body weight loss incidences linked to TPM therapy vary widely and, in some cases, are very conflicting.

Aims: The aims of this review are to quantify TPM-induced weight loss, analyze the pathogenetic mechanisms and evaluate its clinical implications in patients with epilepsy.

Results: The amount of weight loss appears to be related to some factors such as the duration of the treatment and a high baseline body mass index (BMI), while the role of daily dosage and gender of patients is controversial. The mechanism through which TPM may induce weight loss is still unclear.

Interpretation: TPM is able to induce weight loss, especially in high baseline BMI patients, not strictly depending on daily dosage and perhaps not influenced by gender. This makes TPM a good choice, especially in obese patients suffering from seizures. However, TPM can make nutritionally vulnerable children or adult patients, with epilepsy associated with other neuropsychiatric diseases, who cannot voluntarily increase their caloric intake.
