Application Number:	08/660,331
Patent Claims:	1. A method for the treatment or prophylaxis of hypertension in an adult human patient, which comprises administering to the patient, on a daily basis, an effective amount of a pharmaceutical composition in which the active ingredients consist essentially of a mixture of fatty acids of which at least 80% by weight is comprised of a combination of (all-Z omega-3)-5,8,11,14,17-eicosapentaenoic acid (EPA) and (all-Z omega-3)-4,7,10,13,16,19-docosahexaenoic acid (DHA) in a weight ratio of EPA:DHA of from 1:2 to 2:1 and of which at least 1% by weight of the mixture of fatty acids is comprised of (all-Z omega-3)-6,9,12,15,18-heneicosapentaenoic acid. 2. The method of claim 1, wherein at least 85% by weight of the mixture of fatty acids is comprised of long chain omega-3 fatty acids. 3. The method of claim 2, wherein the EPA constitutes 40 to 60% by weight of the mixture of fatty acids and the DHA constitutes 25 to 45% by weight of the mixture of fatty acids. 4. The method of claim 3, wherein the EPA and DHA are present in the composition in an EPA:DHA weight ratio of from 1:1 to 2:1. 5. The method of claim 4, wherein the composition is administered orally. 6. The method of claim 4, wherein at least 3% by weight of the mixture of fatty acids is comprised of omega-3 fatty acids other than EPA and DHA that have 20, 21, or 22 carbon atoms. 7. The method of claim 6, wherein at least 90% by weight of the composition is comprised of long chain, polyunsaturated, omega-3 fatty acids. 8. The method of either of claims 6 or 7, wherein the fatty acids are present in the composition in esterified form. 9. The method of either of claims 6 or 7, wherein the fatty acids are present in the composition in ethyl ester form. 10. The method of either of claims 6 or 7, wherein the fatty acids are present in the composition in the free acid form. 11. The method of claim 7, wherein at least 85% by weight of the fatty acid content of the composition is comprised of the combination of EPA and DHA, and the fatty acids are present in the composition in ethyl ester form. 12. A method for the treatment or prophylaxis of multiple risk factors for cardiovascular diseases, which comprises administering to a patient a mixed-fatty acids composition in which a) at least 80% by weight of the composition is comprised of omega-3 fatty acids, b) at least 80% by weight of the total fatty acid content of the composition is comprised of a combination of (all-Z omega-3)-5,8,11,14,17-eicosapentaenoic acid (EPA) and (all-Z omega-3)-4,7,10,13,16,19-docosahexaenoic acid (DHA) in a weight ratio of EPA:DHA of from 1:2 to 2:1, c) at least 1% by weight of the total fatty acid content of the composition is comprised of (all-Z omega-3)-6,9,12,15,18-heneicosapentanoic acid, and d) the fatty acids are in admixture with a pharmaceutically acceptable carrier. 13. A method for the treatment or prophylaxis of multiple risk factors for cardiovascular diseases in an adult human patient, which comprises orally administering to the patient a pharmaceutical composition in which the active ingredients consist essentially of a mixture of fatty acids of which at least 80% by weight is comprised of a combination of (all-Z omega-3)-5,8,11,14,17-eicosapentaenoic acid (EPA) and (all-Z omega-3)-4,7,10,13,16,19-docosahexaenoic acid (DHA) in a weight ratio of EPA:DHA of from 1:2 to 2:1, and of which at least 1% by weight of the mixture of fatty acids is comprised of (all-Z omega-3)-6,9,12,15,18-heneicosapentaenoic acid, said composition being administered in amounts providing a daily dosage of 1 to 10 grams of said mixture of fatty acids. 14. The method of claim 13, wherein at least 85% by weight of the mixture of fatty acids is comprised of long chain omega-3 fatty acids. 15. The method of claim 14, wherein the EPA constitutes 40 to 60% by weight of the mixture of fatty acids and the DHA constitutes 25 to 45% by weight of the mixture of fatty acids. 16. The method of claim 15, wherein the EPA and DHA are present in the composition in an EPA:DHA weight ratio of from 1:1 to 2:1. 17. The method of claim 16, wherein at least 3% by weight of the mixture of fatty acids is comprised of omega-3 fatty acids other than EPA and DHA that have 20, 21, or 22 carbon atoms. 18. The method of claim 16, wherein at least 4.5% by weight of the mixture of fatty acids is comprised of fatty acids other than EPA and DHA that have 20, 21, or 22 carbon atoms. 19. The method of either of claims 18 or 17, wherein the fatty acids are present in the composition in esterified form. 20. The method of either of claims 18 or 17, wherein the fatty acids are present in the composition in ethyl ester form. 21. The method of either of claims 18 or 17, wherein the fatty acids are present in the composition in salt form. 22. The method of either of claims 18 or 17, wherein the fatty acids are present in the composition in the free acid form.
