The mechanism of action of biguanides is not fully understood, and many mechanisms have been proposed for metformin. [citation needed] Biguanides do not affect the output of insulin, unlike other hypoglycemic agents such as sulfonylureas and meglitinides. Therefore, they are effective in Type 2 diabetics; and in Type 1 diabetes when used in ...
Bisbiguanides are a class of chemically related compounds known for their bactericidal properties. Generally considered to be of the generic formula: R 1 R 2 N.C (:NR 6)NH.C (:NH)NH.CH 2 X-- (CH 2) 3 NH.C (:NH)NH.C (:NR 7)NR 3 R 4 V. [1] These compounds include the antiseptics chlorhexidine and alexidine. They are named for having two biguanide ...
Buformin and the other biguanides are not hypoglycemic, but rather antihyperglycemic agents. They do not produce hypoglycemia; instead, they reduce basal and postprandial hyperglycemia in diabetics. [5] Biguanides may antagonize the action of glucagon, thus reducing fasting glucose levels. [6]
Biguanides reduce hepatic glucose output and increase uptake of glucose by the periphery, including skeletal muscle. Although it must be used with caution in patients with impaired liver or kidney function, Metformin, a biguanide, has become the most commonly used agent for type 2 diabetes in children and teenagers. Among common diabetic drugs ...
Metformin inhibits cyclic AMP production, blocking the action of glucagon, and thereby reducing fasting glucose levels. [111] Metformin also induces a profound shift in the faecal microbial community profile in diabetic mice, and this may contribute to its mode of action possibly through an effect on glucagon-like peptide-1 secretion.

Proguanil (chloroguanide) is a biguanide; a synthetic derivative of pyrimidine. It was developed in 1945 by a British Antimalarial research group. It has many mechanisms of action but primarily is mediated through conversion to the active metabolite cycloguanil. This inhibits the malarial dihydrofolate reductase enzyme.
Alpha-glucosidase inhibitor. Alpha-glucosidase inhibitors (AGIs) are oral anti-diabetic drugs used for diabetes mellitus type 2 that work by preventing the digestion of carbohydrates (such as starch and table sugar). Carbohydrates are normally converted into simple sugars (monosaccharides) by alpha-glucosidase enzymes present on cells lining ...
In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. [2] A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor . [ 3 ]
