RESUMEN
There have been concerns that neuraminidase inhibitors (oseltamivir, zanamivir, laninamivir, and peramivir) cause neuropsychiatric adverse events (NPAEs). We evaluated the number of relevant reports, reporting ratio, and reporting odds ratio (ROR) by using spontaneous reporting database, such as the Japanese Adverse Drug Event Report (JADER) (April 2004 to July 2014). The RORs of oseltamivir, zanamivir, laninamivir, and peramivir were 11.8 (95% confidence interval (CI), 10.8-13.0), 47.0 (95% CI, 40.0-55.3), 9.5 (95% CI, 6.8-13.2), and 3.3 (95% CI, 2.1-5.1), respectively. The lower limit of the ROR 95% CI of NPAEs of all neuraminidase inhibitors was ≥1. We analyzed the association of age and gender with NPAEs in patients treated with oseltamivir using a logistic regression model. The adjusted ROR of NPAEs was 66.9 (95% CI, 50.3-88.9) in male patients treated with osletamivir aged 10-19 years. The adjusted RORs of NPAEs were increased in male and female patients under the age of 20 years. Neuraminidase inhibitors including oseltamivir treatment could be associated with NPAEs. Therefore, these drugs should be used carefully in clinical practice.
