Elimination: 45% of drug is excreted from urine in the unchanged form [3]
Half-life: The concentration or amount of drug in body reduced by one-half in 1.3 - 4.4 hours [4]
MRTD: The Maximum Recommended Therapeutic Dose (MRTD) of drug that ensured maximising efficacy and moderate side effect is 555.97803 micromolar/kg/day [5]
Unbound Fraction: The unbound fraction of drug in plasma is 0.7% [4]
Vd: Fluid volume that would be required to contain the amount of drug present in the body at the same concentration as in the plasma 0.09 L/kg [4]
