Patent Claims:	1. A method of treating amyotrophic lateral sclerosis, comprising: orally or intragastrically administering, to a subject in need thereof, a liquid pharmaceutical composition comprising edaravone with a first time interval from a consumption of a meal by the subject in need thereof to an administration of the liquid pharmaceutical composition to the subject in need thereof such that the first time interval achieves the same pharmacokinetics as administration of the liquid pharmaceutical composition by the same method to the subject under a fasting condition of 10 hours or longer and that the same pharmacokinetics includes Cmax and AUC, wherein the liquid pharmaceutical composition is administered to the subject in need thereof such that a dose of edaravone per administration is in a range of 90 to 120 mg, the first time interval for the consumption of a high-fat meal in a range of 800 to 1000 calories with 50% fat is 8 hours before the administration of the liquid pharmaceutical composition to the subject in need thereof, the first time interval for the consumption of a standard meal in a range of 400 to 500 calories with 25% fat is 4 hours before the administration of the liquid pharmaceutical composition to the subject in need thereof, and the first time interval for the consumption of a light meal of 250 calories is 2 hours before the administration of the liquid pharmaceutical composition to the subject in need thereof. 2. The method of claim 1, further comprising: setting a second time interval from the administration of the liquid pharmaceutical composition to a consumption of a next meal by the subject in need thereof such that the second time interval is 30 minutes or longer after the administration of the liquid pharmaceutical composition. 3. The method of claim 1, further comprising: setting a second time interval from the administration of the liquid pharmaceutical composition to a consumption of a next meal by the subject in need thereof such that the second time interval is 1 hour or longer after the administration of the liquid pharmaceutical composition. 4. The method of claim 1, wherein the administration of the liquid pharmaceutical composition is oral administration. 5. The method of claim 1, wherein the administration of the liquid pharmaceutical composition is intragastric administration. 6. The method of claim 5, wherein the intragastric administration is administration via one of a percutaneous endoscopic gastrostomy catheter and a nasopharyngeal gastric catheter. 7. The method of claim 1, wherein the liquid pharmaceutical composition includes a dispersant. 8. The method of claim 1, wherein the liquid pharmaceutical composition includes a dispersant, a thickener and a stabilizer. 9. The method of claim 1, wherein the liquid pharmaceutical composition is administered to the subject in need thereof intermittently or daily such that the first time interval is a time interval during an administration period of an intermittent or daily administration. 10. The method of claim 1, wherein the liquid pharmaceutical composition is administered to the subject in need thereof such that a dose of edaravone per administration is in a range of 90 to 105 mg. 11. The method of claim 1, wherein the liquid pharmaceutical composition is administered to the subject in need thereof such that a dose of edaravone per administration is in a range of 100 to 105 mg. 12. The method of claim 1, wherein the liquid pharmaceutical composition is administered to the subject in need thereof such that a frequency of a daily administration is once and that a dose of edaravone per administration is 105 mg. 13. The method of claim 2, wherein the administration of the liquid pharmaceutical composition is oral administration. 14. The method of claim 2, wherein the administration of the liquid pharmaceutical composition is intragastric administration. 15. The method of claim 2, wherein the liquid pharmaceutical composition includes a dispersant. 16. The method of claim 2, wherein the liquid pharmaceutical composition includes a dispersant, a thickener and a stabilizer. 17. The method of claim 2, wherein the liquid pharmaceutical composition is administered to the subject in need thereof intermittently or daily such that the first time interval is a time interval during an administration period of an intermittent or daily administration. 18. The method of claim 2, wherein the liquid pharmaceutical composition is administered to the subject in need thereof such that a dose of edaravone per administration is in a range of 90 to 105 mg. 19. The method of claim 2, wherein the liquid pharmaceutical composition is administered to the subject in need thereof such that a dose of edaravone per administration is in a range of 100 to 105 mg. 20. The method of claim 2, wherein the liquid pharmaceutical composition is administered to the subject in need thereof such that a frequency of a daily administration is once and that a dose of edaravone per administration is 105 mg.
