[New possibilities in clinical use of angiotensin II receptor inhibitors].
The use of angiotensin-receptor blockers has already been outlined in cardiology and diabetology. In extending clinical indications of this drug class their pleiotropic actions might play a role: they are improving endothelial function, and their antiatherogenic effect is not related to antihypertensive action. It may also be important that while some antihypertensive agents are impairing sexual function, angiotensin-receptor blocking agents seem to improve sexual activity in hypertensive men. As there is alternative route for angiotensin II synthesis, there are patients in whom blockade of angiotensin II actions do need more aggressive treatment for proper therapeutic results. The discovery of angiotensin-receptor blocking agents made possible to produce this blockade in the tissues as well, and suggested combined administration of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers for better clinical results. In patients with congestive heart failure data from an earlier pilot study (RESOLVD) suggested that combined use of these two drug classes would lead for a more complete blockade of the renin-angiotensin system with better clinical results, especially in those patients in the higher dose ranges. Recent results showed that using this drug combination cardiovascular mortality and hospitalization because of worsening heart failure could significantly be decreased (CHARM-Added study). More important data are expected from the ongoing ONTARGET program (Ongoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial).
