After oral administration, it is almost completely absorbed. Has a high degree of lipid solubility and low affinity for calcium binding. Stable in plasma. C_max – 3.61 μg / ml, the elimination rate constant is 0.049 per hour. T_1 / 2 in plasma is from 10 to 20 hours (mainly – 12-14 hours, on average – 16.3 hours).
