| 摘要 |
The present invention relates to the administration of thrombolytic reagents such as tissue plasminogen activator (t-PA), streptokinase and/or urokinase, over prolonged periods of time for prevention of vascular disease such as cerebral vascular thrombosis, pulmonary embolism, deep venous thrombus, acute myocardial infarction and fresh or aged arterial thrombi. The invention relates generally to delivery systems that provide for sustained release of thrombolytic reagents such as tissue plasminogen activator (t-PA), streptokinase and/or urokinase, over prolonged periods of time. The thrombolytic reagents may be administered, for example, transdermally, topically, intranasally or orally.
