Method of using combination preparation comprising angiotensin-II-receptor blocker and HMG-CoA reductase inhibitor
Disclosed herein is a combination therapy and a combination preparation of an angiotensin-II-receptor blocker and an HMG-CoA reductase inhibitor characterized in that the angiotensin-II-receptor blocker is absorbed substantially later than the HMG-CoA reductase inhibitor. As the angiotensin-II-receptor blocker and the HMG-CoA reductase inhibitor are released at different times, the present combination therapy prevents competitive inhibition between the two drugs and side effects, as well as simultaneously provides synergistic effects for each active ingredient and convenience of taking the drugs.
1. A method of preventing or treating hypertension, hyperlipidemia, cardiovascular diseases, cardiopulmonary diseases, pulmonary diseases, renal disorders, or metabolic syndromes, which comprises administrating to a subject a therapeutically effective amount of an angiotensin-II-receptor blocker and an HMG-CoA reductase inhibitor, wherein the angiotensin-II-receptor blocker is absorbed substantially later than the HMG-CoA reductase inhibitor.
2. The method of claim 1 , wherein the administration is performed such that the angiotensin-II-receptor blocker is absorbed 1.5-6 hours substantially later than the HMG-CoA reductase inhibitor.
3. The method of claim 1 , wherein the angiotensin-II-receptor blocker and the HMG-CoA reductase inhibitor are administrated in the form of a combination preparation.
4. The method of claim 3 , wherein the combination preparation is designed so that release of angiotensin-II-receptor blocker is delayed substantially later than the HMG-CoA reductase inhibitor, thereby angiotensin-II-receptor blocker is absorbed 1.5-6 hours substantially later than the HMG-CoA reductase inhibitor.
5. The method of claim 4 , wherein the angiotensin-II-receptor blocker is lag time delayed released such that a dissolution rate of the angiotensin-II-receptor blocker is less than 10% up to a total of 120 minutes, and less than 20% up to a total of 240 minutes.
6. The method of claim 4 , wherein the combination preparation is administrated between 5 p.m, and 10 p.m, once a day.
7. The method of claim 1 , wherein the angiotensin-II-receptor blocker and the HMG-CoA reductase inhibitor are administrated in the form of single preparations.
8. The method of claim 1 , wherein the angiotensin-II-receptor blocker is administrated 1.5-6 hours later than the HMG-CoA reductase inhibitor.
9. The method of claim 1 , wherein the angiotensin-II-receptor blocker is one or more components selected from the group consisting of losartan, valsartan, irbesartan, candesartan, telmisartan, eprosartan, olmesartan and pharmaceutically acceptable salts thereof.
10. The method of claim 1 , wherein the HMG-CoA reductase inhibitor is one or more components selected from the group consisting of simvastatin, lovastatin, atorvastatin, pitavastatin, rosuvastatin, fluvastatin, pravastatin and pharmaceutically acceptable salts thereof.
