Claims
- 1. A method of reducing adverse physiological effects due to parenteral administration of particulate drugs in a patient in need thereof comprising administering to said patient a therapeutically effective amount of a nitric oxide synthetase inhibitor or nitric oxide antagonist.
- 2. The method of claim 1 wherein said nitric oxide synthetase inhibitor or nitric oxide antagonist is a nitric oxide synthetase inhibitor.
- 3. The method of claim 2 wherein said nitric oxide synthetase inhibitor is an L-arginine analog.
- 4. The method of claim 2 wherein said nitric oxide synthetase inhibitor or nitric oxide antagonist is N-.omega.-nitro-L-arginine.
- 5. The method of claim 1 wherein said particulate drug is a diagnostic imaging contrast agent composition.
- 6. The method as claimed in claim 5 wherein said composition is an echogenic contrast agent for ultrasound imaging.
- 7. The method as claimed in claim 5 wherein said composition is an X-ray contrast medium.
- 8. The method of claim 1 wherein said particulate drug is a composition comprising gas microbubbles, an emulsion containing droplets of a volatile liquid or a mixture thereof.
- 9. A pharmaceutical composition in a form adapted for parenteral administration comprising a particulate drug and a nitric oxide synthetase inhibitor or nitric oxide antaonist.
- 10. A kit comprising a first pharmaceutical composition in a form adapted for parenteral administration comprising a particulate drug together with at least one physiologically tolerable carrier or excipient and a second pharmaceutical composition comprising a nitric oxide synthetase inhibitor or nitric oxide antagonist together with at least one physiologically tolerable carrier or excipient, optionally together with instructions for separate or simultaneous administration of said first and said second pharmaceutical compositions.
- 11. A kit as claimed in claim 10, wherein said particulate drugs is a diagnostic imaging contrast agent composition.
- 12. A kit as claimed in claim 11, wherein said nitric oxide synthetase inhibitor or nitric oxide antagonist is an L-arginine analog.
- 13. A method of reducing adverse physiological effects due to parenteral administration of a particulate drug in a patient in need thereof, said method comprising parenterally administering to said patient a particulate drug and previously, simultaneously or subsequently administering to said patient a side-effect reducing amount of a nitric oxide synthetase inhibitor or nitric oxide antagonist.
- 14. A method as claimed in claim 13, wherein said nitric oxide synthetase inhibitor or nitric oxide antagonist is an L-arginine analog and particulate drug is a diagnostic imaging contrast agent composition.
- 15. A method as claimed in claim 14, wherein said nitric oxide synthetase inhibitor or nitric oxide antagonist is N-.omega.-nitro-L-arginine.
- 16. A method as claimed in claim 14, wherein said composition is an echogenic contrast agent for ultrasound imaging or an X-ray contrast medium.
- 17. A method as claimed in claim 15, wherein said particulate drug is a composition comprising gas microbubbles, an emulsion containing droplets of a volatile liquid or a mixture thereof.
- 18. A composition as claimed in claim 9, wherein said nitric oxide synthetase inhibitor or nitric oxide antagonist is an L-arginine analog and the particulate drug is a diagnostic imaging contrast agent composition.
- 19. A composition as claimed in claim 9, wherein said nitric oxide synthetase inhibitor or nitric oxide antagonist is or N-.omega.-nitro-L-arginine.
- 20. A composition as claimed in claim 18, wherein said particulate drug composition is an echogenic contrast agentfor ultrasound imaging or an X-ray contrast medium.
- 21. A composition as claimed in claim 20, wherein said particulate drug is a composition comprising gas microbubbles, an emulsion containing droplets of a volatile liquid or a mixture thereof.
