In pharmacology, potency or biological potency [1] is a measure of a drug's biological activity expressed in terms of the dose required to produce a pharmacological effect of given intensity. [2]
Type 2 diabetes mellitus is the most common type of diabetes. Treatments include agents that (1) increase the amount of insulin secreted by the pancreas, (2) increase the sensitivity of target organs to insulin, (3) decrease the rate at which glucose is absorbed from the gastrointestinal tract, and (4) increase the loss of glucose through ...
It is commonly used as a measure of a drug's potency, although the use of EC 50 is preferred over that of 'potency', which has been criticised for its vagueness. [3] EC 50 is a measure of concentration, expressed in molar units (M), where 1 M is equivalent to 1 mol/L.
The parameters of the dose response curve reflect measures of potency (such as EC50, IC50, ED50, etc.) and measures of efficacy (such as tissue, cell or population response). A commonly used dose–response curve is the EC 50 curve, the half maximal effective concentration, where the EC 50 point is defined as the inflection point of the curve.
In type 1 diabetes, insulin production is extremely low, and as such the body requires exogenous insulin. Some people with type 2 diabetes, particularly those with very high hemoglobin A1c values, may also require a baseline rate of insulin, as their body is desensitized to the level of insulin being produced. Basal insulin regulates the body's ...
Type 1 diabetes (T1D), formerly known as juvenile diabetes, is an autoimmune disease that occurs when pancreatic cells (beta cells) are destroyed by the body's immune system. [5] In healthy persons, beta cells produce insulin. Insulin is a hormone required by the body to store and convert blood sugar into energy. [6]
A drug's potency can be affected (the response curve shifted to the right) by the presence of an antagonistic interaction. Pharmacodynamic interactions can occur on protein receptors . [ 5 ] Two drugs can be considered to be homodynamic , if they act on the same receptor.
In patients with diabetes mellitus type 1, alpha-glucosidase inhibitors use has not been officially approved by the Food and Drug Administration in the US but some data exists on the effectiveness in this population, showing potential benefits weighted against an increased risk of hypoglycemia. [18]
