Acetohexamidum

Acetohexamidum Uses, Dosage, Side Effects, Food Interaction and all others data.

A sulfonylurea hypoglycemic agent that is metabolized in the liver to 1-hydrohexamide. Acetohexamidum has been discontinued in the US market.

Acetohexamidum 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. Acetohexamidum has one-third the potency of chlorpropamide, and twice the potency of tolbutamide; however, similar hypoglycemic efficacy occurs with equipotent dosage of sulfonylureas.

Uses

Used in the management of diabetes mellitus type 2 (adult-onset).

How Acetohexamidum works

Sulfonylureas such as acetohexamide bind to an ATP-dependent K⁺ 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 Ca²⁺ channels. The rise in intracellular calcium leads to increased fusion of insulin granulae with the cell membrane, and therefore increased secretion of (pro)insulin.

Toxicity

Oral, rat LD₅₀: 5 gm/kg; Oral, mouse LD₅₀: >2500 mg/kg. Symptoms of an acetohexamide overdose include hunger, nausea, anxiety, cold sweats, weakness, drowsiness, unconsciousness, and coma.

Food Interaction

Avoid alcohol.
Take with or without food. The absorption is unaffected by food.

[Moderate] GENERALLY AVOID: Alcohol may cause hypoglycemia or hyperglycemia in patients with diabetes.

Hypoglycemia most frequently occurs during acute consumption of alcohol.

Even modest amounts can lower blood sugar significantly, especially when the alcohol is ingested on an empty stomach or following exercise.

The mechanism involves inhibition of both gluconeogenesis as well as the counter-regulatory response to hypoglycemia.

Episodes of hypoglycemia may last for 8 to 12 hours after ethanol ingestion.

By contrast, chronic alcohol abuse can cause impaired glucose tolerance and hyperglycemia.

Moderate alcohol consumption generally does not affect blood glucose levels in patients with well controlled diabetes.

A disulfiram-like reaction (e.g., flushing, headache, and nausea) to alcohol has been reported frequently with the use of chlorpropamide and very rarely with other sulfonylureas.

MANAGEMENT: Patients with diabetes should avoid consuming alcohol if their blood glucose is not well controlled, or if they have hypertriglyceridemia, neuropathy, or pancreatitis.

Patients with well controlled diabetes should limit their alcohol intake to one drink daily for women and two drinks daily for men (1 drink = 5 oz wine, 12 oz beer, or 1.5 oz distilled spirits) in conjunction with their normal meal plan.

Alcohol should not be consumed on an empty stomach or following exercise.
