Benefits of technology

[0170] Pharmaceutical effect: refers to an effect observed upon administration of an agent intended for treatment of a disease or disorder or for amelioration of the symptoms thereof.
[0171] Pharmacodynamic: An effect mediated by drug action.

Problems solved by technology

Current oral formulations of diazoxide in therapeutic use result in a range of adverse side effects including dyspepsia, nausea, diarrhea, fluid retention, edema, reduced rates of excretion of sodium, chloride, and uric acid, hyperglycemia, vomiting, abdominal pain, ileus, tachycardia, palpitations, and headache (see current packaging insert for the Proglycem).
Oral treatment with diazoxide is used in individuals experiencing serious disease where failing to treat results in significant morbidity and mortality.
The adverse side effects profile of oral diazoxide limit the utility of the drug in treating obese patients at doses within the labeled range of 3 to 8 mg / kg per day.

A. Potassium ATP Channel Activator Containing Formulations:

[0399] 1. Compressed Tablet Formulations

[0400] Diazoxide or a derivative thereof at about 15-30% by weight is mixed with hydroxypropyl methylcellulose at about 55-80% by weight, ethylcellulose at about 3-10 wt / vol % and magnesium stearate (as lubricant) and talc (as glidant) each at less than 3% by weight. The mixture is used to produce a compressed tablet as described in Reddy et al., AAPS Pharm Sci Tech 4(4):1-9 (2003). The tablet may be coated with a thin film as discussed below for microparticles.

[0401] A tablet containing 100 mg of diazoxide or a derivative thereof will also contain approximately 400 mg of hydroxypropyl cellulose and 10 mg of ethylcellulose. A tablet containing 50 mg of diazoxide or a derivative thereof will also contain approximately 200 mg of hydroxypropyl cellulose and 5 mg of ethylcellulose. A tablet containing 25 mg of diazoxide or a derivative thereof will also contain approximately 100 mg of ...
