Abstract

Objective: To evaluate the efficacy of extended-release quetiapine fumarate (XR) monotherapy once daily, in the treatment of patients with acute episodes of schizophrenia and agitation. Method: Our study was a 3-week open-label study conducted in adult in- or outpatients with schizophrenia. Quetiapine XR was initiated at 300 mg on day 1, 600 mg on day 2, and 400-800 mg (at the investigator’sdiscretion) on day 3 and onwards. The primary endpoint was the change from baseline in the Positive and Negative Syndrome Scale Excited Component (PANSS- EC) score. Secondary endpoints included change from baseline in PANSS-Positive, PANSS-Negative, PANSS- General Psychopathological (PANSS-G) subscale scores, total PANSS score, PANSS aggression, hostility and depression cluster scores, CGI-Severity of illness (CGI- S) and the absolute CGI-Improvement (CGI-I) scales. Tolerability was assessed based on reported adverse events (AEs), the Simpson-Angus Scale (SAS) and Barnes Akathisia Rating Scale (BARS) scores, laboratory measurements and electrocardiograms (ECGs). Results: Of 40 patients enrolled, 35 completed the study. At day 21, statistically significant improvements versus baseline were seen for the primary and all secondary endpoints assessed. The incidence of AEs was low, and all were mild to moderate in severity. No extrapyramidal symptoms (EPS) as measured by the SAS and BARS were reported, indicating that the treatment was well tolerated. Hospitalization was required in one out-patient due to a relapse of psychosis, but was not considered to be treatment related. Conclusion: Once-daily quetiapine fumarate XR (400- 800 mg/day) was effective in reducing agitation and a broad range of symptoms in acute schizophrenia. Treatment, including rapid dose escalation, was generally well tolerated in this study.

Özet

Amaç: Bu çalışmada, akut şizofreni hastalarında ajitasyonun tedavisinde uzamış salınımlı ketiyapin fumarat’ın (XR) etkinliğini değerlendirmek amaçlandı. Yöntem: Üç haftalık açık etiketli olarak tasarlanan buçalışmaya yatan veya ayaktan şizofreni hastaları dahiledildi. Ketiyapin XR 1. gün 300 mg, 2. gün 600 mg ve 3. günden itibaren araştırmacının takdirine göre 400-800mg/gün dozunda uygulandı. Birincil sonlanım noktasıolarak bazal Pozitif ve Negatif Semptom Skalasının Eksite Bileşeni (PANSS-EC) puanındaki değişim alın-dı. İkincil sonlanım noktası olarak bazal PANSS-Pozitif,PANSS-Negatif, PANSS-Genel Psikopatoloji (PANSS-G)alt ölçek skorları ile toplam PANSS skoru, PANSS agres- yon, hostilite ve depresyon skorları, CGI-Hastalık Şiddeti (CGI-S) ve CGI-İyileşme (CGI-I) puanlarındaki değişim esas alındı. Tolerabilitenin değerlendirmesi amacıyla bildirilen yan etkiler (YE), Simpson-Angus Ölçeği (SAÖ), Barnes Akatizi Derecelendirme Ölçeği (BADÖ), labora- tuvar ölçümleri ve elektrokardiyogram (EKG) kullanıldı.Sonuç: Çalışmaya alınan 40 hastadan 35’i çalışmayı tamamlamıştır. Yirmi birinci günde birincil ve ikincil sonlanım noktası değerlendirmelerinde başlangıcagöre istatistiksel olarak anlamlı değişme gözlendi. YEinsidansı düşüktü ve tüm yan etkiler hafif orta şid-detteydi. SAÖ ve BADÖ ile yapılan değerlendirmeyegöre hiç ekstrapiramidal semptom (EPS) saptanmadı ve tedavi iyi tolere edildi. Bir hastada psikozun relapsınedeniyle hospitalizasyon gerekti, ancak bu durumuntedaviyle ilişkisi olmadığı değerlendirildi.Sonuç: Günde tek doz ketiyapin fumarat akut şizofrenisemptomlarının ve ajitasyonun azaltılmasında etkilidir.Bu çalışmada, hızlı doz titrasyonuna rağmen tedavi genel olarak iyi tolere edilmiştir.
