Abstract

A method of treatment of the human or non-human animal body for treating NO-dependent microcirculation disorders is disclosed, for example microcirculation disorders caused by metabolic diseases, such as elevated levels of homocystin-homocystein inflammatory reactions or autoimmune diseases, furthermore peripheral microcirculation disorders or microcirculation disorders associated with increased cell fragmentation, which method comprises administering to a human or non-human animal body in need of such treatment an effective amount of a pharmaceutical composition containing a substance which scavenges free radicals, e.g. a pyrimido-pyrimidine selected from Dipyridamole, Mopidamol and the pharmaceutically acceptable salts thereof, and the use such substance for the manufacture of a corresponding pharmaceutical composition, optionally in combination with an agent capable of increasing NO procution.

Claims

1. A pharmaceutical composition for treating NO-dependent microcirculation disorders comprising dipyridamole or a pharmaceutically acceptable salt thereof in combination with one or more HMG CoA reductase inhibitors.

2. The pharmaceutical composition of claim 1, wherein administration of the composition to an animal results in a maintained plasma level of about 0.2 to 5 μ

mol/L of dipyridamole.

3. The pharmaceutical composition of claim 1, wherein the composition is administered orally in a sustained or controlled release formulation.

4. The pharmaceutical composition of claim 1, wherein the composition is administered parenterally.

5. The pharmaceutical composition of claim 1, wherein the dipyridamole is administered orally in a daily dosage of 25 to 450 mg or parenterally in a dosage of 0.5 to 5 mg/kg body weight over 24 hours.

6. The pharmaceutical composition of claim 1 wherein the HMG CoA reductase inhibitor may be one or more selected from the group consisting of:

lovastatin,

pravastatin,

simvastatin,

fluvastatin,

dalvastatin,

compactin, mevastatin,

HR 780,

BMY 22,089,

BMY 22,566,

SQ 33,600,

GR 95,030 and

CI 981.

7. The pharmaceutical composition of claim 1 wherein the HMG CoA reductase inhibitor is selected from the group consisting of:

lovastatin,

pravastatin,

simvastatin,

fluvastatin,

dalvastatin, and

mevastatin.

8. The pharmaceutical composition of claim 1 wherein the HMG CoA reductase inhibitor is pravastatin.
