Treatment of Interictal Depression with Citalopram in Patients with Epilepsy.
The purpose of this study is to assess the efficacy and safety of the selective serotonin-reuptake inhibitor (SSRI) citalopram in depressed epileptic patients. We evaluated 43 epileptic patients who suffered from depression and whose total score on the 21 items of the Hamilton Scale for Depression (HAMD 21) exceeded 15 points. These patients were examined by the psychiatrist and scaled before treatment and after 4 and 8 weeks of treatment with citalopram. The dose of citalopram was flexible, related to the actual condition of the patient. In each patient and in the whole group of patients we compared the monthly seizure frequency (total, partial seizures, generalized tonic-clonic seizures) recorded during treatment with citalopram with that recorded during the 2 months preceding the start of citalopram. During treatment we observed a decrease in the total score on the HAMD 21 from a mean initial value of 21.5 +/- 2.9 (range, 17-26) prior to therapy 14.5 +/- 2.9 (range, 10-19) (P < 0.001) after 4 weeks of treatment and to 9.9 +/- 3.1 (range, 4-19) (P < 0.001) after 8 weeks of treatment. There were 9 (20.9%) responders after 4 weeks of treatment and 28 responders (65.1%) after 8 weeks, all of them with decrease on the HAMD 21 greater than 50%. Nausea was the most common adverse event in 7 patients (16.3%) during the first month of treatment and in 3 patients (6.9%) during the second month of treatment. Sexual dysfunction (decrease of libido) was reported in 2 (4.7%) male patients during the entire course of treatment. No seizure worsening was observed in our patients. Monthly seizure frequency did not change significantly: 2.24 (+/-0.76) seizures before treatment with citalopram, 2.29 (+/-0.81) seizures in the first month of treatment, 2.21 (+/-1.00) seizures in the second month of treatment. No occurrence of de novo generalized tonic-clonic seizures was recorded in individual patients. Citalopram is a safe and effective antidepressant in the treatment of depressed epileptic patients.
