Abstract

An open clinical trial was carried out to compare the efficacy and the tolerability of 1 g/day α-glycerylphosphorylcholine (α-GPC) with 1 g/day cytosine diphosphocholine (CDP) both given intramuscularly for 90 days in 120 patients with mild to moderate vascular dementia. The clinical evaluation, carried out at the start as well as halfway through (45 days) and at the end of treatment (90 days), was expressed by psychometric tests (modified Parkside behaviour rating scale, Sandoz clinical assessment geriatric scale, word fluency test, Hamilton's rating scale of depression, narration subtest of Wechsler memory scale). Both treatments produced a definite symptomatic improvement and showed a very good tolerability. The results suggest that in most tests α-GPC possessed a statistical higher efficacy and an overall more satisfactory activity assessed by both patients and investigators compared with CDP. E’ stato effettuato uno studio clinico in aperto per confrontare l'efficacia e la tollerabilità di α-glicerilfosforilcolina (α-GFC) alla dose di 1 g al giorno verso citosina difosfocolina (CDP) sempre alla dose di 1 g al giorno, somminístrate entrambe per via intramuscolare per 90 giorni in 120 pazienti affetti da demenza vascolare di grado da lieve a medio. La valutazione clinica, effettuata all'inizio, a metà (45 giorni) e al termine del trattamento (90 giorni), è stata effettuata con test psicometrici (modified Parkside behaviour rating scale, Sandoz clinical assessment geriatric scale, word fluency test, Hamilton rating scale per la depressione ed subtest del racconto della Wechsler memory scale). Entrambi i trattamenti hanno indotto un miglioramento della sintomatologia e hanno presentato una buona tollerabilità. I risultati mostrano che, nella maggior parte dei test, α-GFC ha presentato una più elevata efficacia, a confronto con CDP, come confermato anche dalle valutazioni soggettive espresse dai pazienti e dagli esaminatori.
