Citicoline Sodium

According to the WHO data, over 35 million people in the world suffer from severe forms of cognitive impairment. Due to the insufficient effectiveness of separate therapy for amyloid or vascular pathologies, an opinion is expressed about the prospects of combined pharmacotherapy of cognitive impairments. The aim of the study was the pharmaceutical development of the combined tablet dosage form formulation with modified release of citicoline and memantine for the treatment of cognitive impairments. Information bases (eLibrary, PubMed) were used, content analysis on State Register of Medicinal Remedies database (grls.rosminzdrav.ru). The compatibility assessment was carried out by stress experiments method in combination with chromatographic analysis. Comparative pharmacokinetic studies were carried out on rabbits. The justification of the pharmacological and clinical feasibility of the proposed fixed dose combination has been carried out, the objective advantage of which is the potentiation of the pharmacotherapeutic action due to the unidirectional effect of memantine and citicoline, and the expected effect is to improve cognition, functioning and behavior and / or slow down their deterioration. The use of the combination will allow achieving ease of treatment, reducing costs, and, accordingly, compliance. The choice of the optimal dosage form for the developed combination was carried out: a tablet containing two release methods: memantine - immediate release, citicoline - prolonged release. The compatibility of the pharmaceutical substances memantine hydrochloride and citicoline monosodium salt with each other and the excipients planned for use in the formulation has been experimentally revealed. Comparative pharmacokinetic studies of the developed combined drug have been carried out.
