Pharmacologie
Isradipine, le plus puissant des canaux calciques agent bloquant de la classe des dihydropyridines, est similaire à la nifédipine, l'amlodipine et la félodipine. Il se lie aux canaux calciques avec une haute affinité et spécificité et inhibe le flux de calcium dans le muscle cardiaque et lisse. Les effets observés dans des expériences in vitro et mécanistiques étudiées chez les animaux intacts et l'homme sont compatibles avec ce mécanisme d'action et sont typiques de la classe.
Rebriden
Absorption
Isradipine est de 90% -95% absorbée et est soumise à un effet de premier passage hépatique, résultant en une biodisponibilité d'environ 15% -24%.

Les rats ont toléré des doses de plus de 2000 mg / kg sans effet sur la survie.
