生物活性
Candesartan cilexetil is a specific nonpeptide Ang II receptor (ATR) antagonist and the prodrug of candesartan which is an ATR antagonist with an IC50 of 15 μg/kg. Candesartan cilexetil efficacy is entirely due to its active metabolite candesartan (CV-11794) and is dose-dependent over the range of 1–8 mg and its clinical antihypertensive dose is stated to be around 4 mg/day.
Candesartan cilexetil is administered as a pro-drug that undergoes activation during gastrointestinal absorption. In clinical trials, candesartan cilexetil has produced a dose-dependent effect when given in dosages of 2-32 mg/day. Observed trough-to-peak blood pressure ratios support a once-daily dosage regimen. The antihypertensive effect of candesartan cilexetil 4-16 mg/day was as great as that of enalapril 10-20 mg/day and amlodipine 5 mg/day and larger than that of losartan potassium 50 mg/day. Adding candesartan cilexetil to hydrochlorothiazide 12.5-25 mg/day and amlodipine 5 mg/day led to enhanced blood-pressure reductions and was well tolerated.

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
