Oral Pharmacokinetics
The activity of Ziprasidone is principally because of parental medicament. Numerous dose pharmacokinetics of ziprasidone is proportional of the dose in the range of offered clinical dose and ziprasidone accumulation is foreseeable with numerous proportion. The elimination of ziprasidone is mainly via the hepatic metabolism with a medium final half-life about 7 hours in the range of offered clinical dose. Permanent concentration is fulfilled in the course of one-three days of proportion. The medium visible systematic permission is 7.5 millilitres / minutes / kg. Ziprasidone will not interfere probably the metabolism of medicaments transformed by metabolism by cytochrome P450 enzymes.
Absorption: Ziprasidone is well-absorbed after the oral administration, by attaining maximum plasma concentration in 6 - 8 hours. Bioavailability absolute of a dose of 20 mgs under fed conditions is 60 %. The absorption of ziprasidone is augmented up to double in the presence of the food.
Distribution: Ziprasidone has a medium visible volume of distribution of 1.5 L / kg. It is bigger than 99 % tied to plasma proteins, by making friends principally in the albumin and in the glycoprotein α1-acid. In the vitro plasma protein making friends of ziprasidone was not changed by warfarin or propranolol, two highly proteinbound medicaments, ziprasidone either changed fact to make friends of these medicaments in plasma human being. So, the potential for the reciprocal actions of medicament with ziprasidone because of displacement is minimal.
