Methods of treating injuries or conditions related to CNS edema
The present technology is related to reducing or treating neurological swelling and related conditions with SUR1-TRPM4 channel inhibitors. In some embodiments, the methods include: reducing late neurological deterioration or preventing death, reducing cerebral midline shift, reducing the degree of disability in a subject, counteracting blood glucose levels in a subject receiving a SUR1-TRPM4 channel inhibitor, preventing brain swelling, monitoring liver enzyme activity along with treating injury or conditions related to CNS edema, or monitoring cardiac activity along with treating injury or conditions related to CNS edema.
1. A method of reducing late neurological deterioration or death in a subject following a large hemispheric infarction, wherein the subject has a brain lesion volume of greater than 100 cc, comprising administering a glyburide to the subject, wherein the administering includes a first continuous infusion and a second continuous infusion of glyburide lasting cumulatively for at least 72 hours after starting the first continuous infusion, wherein the first continuous infusion is started within 9 hours following the subject experiencing the large hemispheric infarction.
2. The method of claim 1 , comprising initiating administration of the glyburide within 1 hour following the subject experiencing the large hemispheric infarction.
3. The method of claim 1 , comprising initiating administration of the glyburide within 4½ hours following the subject experiencing the large hemispheric infarction.
4. The method of claim 1 , comprising initiating administration of the glyburide prior to about 8 hours following the subject experiencing the large hemispheric infarction.
5. The method of claim 1 , wherein administering the continuous infusions of glyburide occur for at least 96 hours.
6. The method of claim 1 , wherein administering the continuous infusions of glyburide occur for at least 120 hours.
7. The method of claim 1 , wherein the first continuous infusion is started after a bolus dose administration.
8. The method of claim 1 , wherein the first continuous infusion has a higher dosage concentration than the second continuous infusion.
9. The method of claim 1 , wherein administering of glyburide is coupled with a decompressive craniectomy.
10. A method of reducing cerebral midline shift in a subject following a large hemispheric infarction, wherein the subject has a brain lesion volume of greater than 100 cc, comprising:
administering to the subject glyburide following the subject experiencing the large hemispheric infarction, wherein the administering includes a first continuous infusion and a second continuous infusion of glyburide lasting cumulatively for at least 72 hours after starting the first continuous infusion, wherein the first continuous infusion is started within 9 hours following the subject experiencing the large hemispheric infarction, wherein the method reduces the cerebral midline shift as determined over a population based on the degree of cerebral midline shift in patients treated with the continuous infusions compared to a similar population that was not treated with the continuous infusions.
11. The method of claim 10 , wherein administering glyburide includes one or more continuous infusion lasting cumulative for at least 72 hours.
12. The method of claim 10 , wherein administering glyburide includes one or more continuous infusion lasting cumulatively for at least 96 hours.
13. The method of claim 10 , wherein the first continuous infusion is started after a bolus dose administration.
14. The method of claim 10 , wherein the first continuous infusion has a higher dosage concentration than the second.
15. The method of claim 1 , further comprising measuring blood glucose levels before or during the administering step.
16. The method of claim 15 , further comprising detecting a blood glucose level in the subject of at or below about 120 mg/dL and administering a dextrose solution to the subject.
17. The method of claim 15 , further comprising detecting a blood glucose level in the subject of at or below about 100 mg/dL and administering a dextrose solution to the subject.
18. The method of claim 15 , further comprising detecting a blood glucose level in the subject of greater than about 80 mg/dL to 100 mg/dL and administering a 3 wt % to 8 wt % solution of dextrose to the subject at from about 50 cc/hr to about 120 cc/hr.
19. The method of claim 15 , further comprising detecting a blood glucose level in the subject of about 55 mg/dL to 80 mg/dL and administering an 8 wt % to 12 wt % solution of dextrose to the subject at from 50 cc/hr to 120 cc/hr.
20. The method of claim 15 , further comprising detecting a blood glucose level in the subject of less 55 mg/dL, and administering an 8 wt % to 12 wt % solution of dextrose to the subject at from 50 cc/hr to 120 cc/hr.
