In certain situations, it may be important to maintain body weight to 200 ug/kg body weight or 0.1 ug/kg body a fairly low dose of the active agent in the blood stream of the weight to 100 ug/kg body weight. Further, those of skill will patient. Such a fairly low dose may include a dose that is less recognize that a variety of different dosage levels will be of than its use in other indications. For example, the typical use, for example, 0.0001 ug/kg, 0.0002 ug/kg, 0.0003 ug/kg, anti-diabetic dose of oral glibenclamide is about 2.5 mg to 0.0004 ug/kg, 0.005 ug/kg, 0.0007 ug/kg, 0.001 ug/kg, 0.1 about 15 mg per day; the typical anti-diabetic dose of oral or g/kg, 1.0 Lig/kg, 1.5ug/kg, 2.0 Lig/kg, 5.0 Lig/kg, 10.0 g/kg.

Where smaller ug/kg, 325 ug/kg, 350 g/kg, 375 g/kg, 400 ug/kg, 450 doses are used, such smaller doses may be, for example, less ug/kg, 500 ug/kg, 550 g/kg, 600 g/kg, 700 lug/kg, 750 than about 2.5 mg/day of glibenclamide, less than about 500 g/kg, 800 g/kg, 900 g/kg, 1 mg/kg, 5 mg/kg, 10 mg/kg, 12 mg per day of tolbutamide, less than about 30 mg per day of mg/kg, 15 mg/kg, 20 mg/kg, and/or 30 mg/kg.

In particular, it is believed that preferred dosages of 0046 For example, in certain embodiments, the amount of glibenclamide for use according to the present invention pro the NSC antagonist administered to the subject is in the range vide between about 0.4 mg to about 10 mg glibenclamide per of about 0.0001 ug/kg/day to about 20 mg/kg/day, about 0.01 day; preferred dosages oftolbutamide for use according to the ug/kg/day to about 100 ug/kg/day, or about 100 ug/kg/day to present invention provide between about 50 mg to about 1000 about 20 mg/kg/day. Still further, the NSC antagonist may be mg tolbutamide per day; and preferred dosages of gliclaZide administered to the subject in the from of a treatment in which for use according to the present invention provide between the treatment may comprise the amount of the NSC antago about 5 mg to about 20 mg gliclaZamide per day. nist or the dose of the NSC antagonist that is administered per 0052. In certain situations, it may be important to maintain day (1, 2, 3, 4, etc.), week (1, 2, 3, 4, 5, etc.), month (1, 2, 3, a fairly high dose of the active agent in the blood stream of the 4, 5, etc.), etc. Treatments may be administered such that the patient, particularly early in the treatment. Such a fairly high amount of NSC antagonist administered to the subject is in dose may include a dose that is several times greater than its the range of about 0.0001 ug/kg/treatment to about 20 mg/kg/ use in other indications. For example, the typical anti-diabetic treatment, about 0.01 ug/kg/treatment to about 100 g/kg/ dose of oral glibenclamide is about 2.5 mg to about 15 mg per treatment, or about 100 ug/kg/treatment to about 20 mg/kg/ day; the typical anti-diabetic dose of oral tolbutamide is about treatment. to 0.5gm to about 3.0 gm per day; the typical anti-diabetic 0047.
