24 hour BP variabillity associated with
increased target organ damage
- During the course of 24 hours, BP fluctuate dramatically, starting with a rapid rise in the morning between 6am and 10 am and falling at night
-Even though office BP is controlled, many patients may still have uncontrolled early morning BP
- Acute Myocardial Infarction has been shown to be three times more common at 9 am than at 11 pm
- 44% of Ischaemic strokes occur in the morning period

MICARDIS unique molecular structures :
Unique pharmacokinetic properties &
pharmacodynamic effects
As evidenced, differences of MICARDIS was :
lipid solubility, volume of distribution, bioavailability, plasma half life,
receptor-binding affinity, and different ways of elimination

effectively controls BP over the full 24-hour period

Summary
1. Hypertension is the most powerful risk factor for the cardiovascular
diseases, including stroke, coronary aretery disease, heart failure, chronic
kidney disease, aortic and peripheral arterial diseases1
2. “Uncontrolled” and “Untreated” hypertension was associated with
increased risk of total and cardiovascular mortality2
3. Antihypertensive agents that minimise the fluctuations in BP observed
over a 24-hour cycle are likely to be most effective in maintaining
reductions in BP and potentially offer the greatest cardiovascular
protection3
4. Telmisartan’s unique pharmacological profile, including highest receptor
affinity, most lipophilic, a long elimination half life (24-h), results in an
sustained control of BP over a 24-hour throughout the once-daily dosing
interval4
5. The powerful and sustained BP control, together with broadest
cardiovascular protection and also better tolerability of Micardis®
(Telmisartan) demonstrated in “ONTARGET” study5
