An amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Acetohexamide is an intermediate-acting, first-generation oral sulfonylurea. It lowers blood sugar by stimulating the pancreatic beta cells to secrete insulin and by helping the body use insulin efficiently. Due to its primary action on the pancreatic beta cells, the drug is only effective when there are functional pancreatic beta cells that can produce insulin granules. Acetohexamide has one-third the potency of chlorpropamide, and twice the potency of tolbutamide; however, similar hypoglycemic efficacy occurs with equipotent dosage of sulfonylureas.
Sulfonylureas such as acetohexamide bind to an ATP-dependent K<sup>+</sup> channel on the cell membrane of pancreatic beta cells. This inhibits a tonic, hyperpolarizing outflux of potassium, which causes the electric potential over the membrane to become more positive. This depolarization opens voltage-gated Ca<sup>2+</sup> channels. The rise in intracellular calcium leads to increased fusion of insulin granulae with the cell membrane, and therefore increased secretion of (pro)insulin.

Sulfonylureas are now...thought to act by a number of different mechanisms. 1. ...produce a depolarization of the pancreatic islet beta cell membrane potassium ion permeability. This results in a release of preformed insulin into the circulation and occurs mostly in non-insulin dependent diabetics. 2. ...reduce basal glucose output from the liver... 3. increase insulin receptor binding... 4. ...increasing intracellular levels of AMP... 5. increase insulin secretion by suppressing the release of glucagon and somatostatin from alpha and delta pancreatic cells. /Sulfonylureas/
Sulfonylureas lower blood glucose in NIDDM by directly stimulating the acute release of insulin from functioning beta cells of pancreatic islet tissue by an unknown process that involves a sulfonylurea receptor on the beta cell. Sulfonylureas inhibit the ATP potassium channels on the beta cell membrane and potassium efflux, which results in depolarization and calcium influx, calcium-calmodulin binding, kinase activation, and release of insulin containing granules by exocytosis, an effect similar to that of glucose. Insulin is a hormone that lowers blood glucose and controls the storage and metabolism of carbohydrates, proteins, and fats. Therefore, sulfonylureas are effective only in patients whose pancreata are capable of producing insulin. /Sulfonylurea antidiabetic agents/

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. If symptoms (such as redness or irritation) develop, immediately transport the victim to a hospital.
SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Sulfonylureas are rapidly absorbed from the gastrointestinal tract, transported in the blood in highly protein-bound complexes, and subjected to extensive hepatic metabolism (except for chlorpropamide). Wide variation exists among the sulfonylureas in hepatic metabolism and remnal clearance, factors that tend to alter the steady-state serum levels. Metabolites may be active, so there may be a variation between the plasma half-life of the parent drug and the degree of hypoglycemia encountered. /Sulfonylurea/
