Claims (25)
(а) время практически полного высвобождения лекарственного вещества из рецептуры, определяемое в соответствии со стандартными протоколами растворимости in vitro с применением контрольной идентификационной среды при значениях рН в интервале 1,2 - 7,0, составляет 4 - 16 ч;
(б) после перорального приема пролонгированных уровней нефазодона относительно таковых, наблюдаемых в случае быстродействующих рецептур, эти пролонгированные уровни остаются равными или превышающими терапевтические уровни на период до 24 ч;
(в) после перорального приема пониженных количеств метаболитов нефазодона, в частности mCPP сохраняется количество нефазодона на уровне, сравнимом с таковым, наблюдаемым при пероральном приеме быстродействующих рецептур; и
(г) отсутствует заметный пищевой эффект при пероральной дозировке.1. An improved pharmaceutical formulation of prolonged action for oral administration of nefazodone or its pharmaceutically acceptable salt, characterized in that:
(a) the time of almost complete release of the drug substance from the formulation, determined in accordance with standard in vitro solubility protocols using the control identification medium at pH values in the range of 1.2-7.0, is 4-16 hours;
(b) after oral administration of prolonged levels of nefazodone relative to those observed in the case of fast-acting formulations, these prolonged levels remain equal to or exceed therapeutic levels for a period of up to 24 hours;
(c) after oral administration of reduced amounts of metabolites of nefazodone, in particular mCPP, the amount of nefazodone is maintained at a level comparable to that observed with oral administration of fast-acting formulations; and
(d) there is no noticeable nutritional effect at oral dosage.
