Beta blockers exert their pharmacological effect, decreased heart rate, by binding to and competitively antagonising a type of receptor called beta adrenoceptors. [1] 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 2021 study in Nutrients found that a high-protein diet was more effective than the Mediterranean diet at reducing insulin resistance and improving glycemic variability—a risk factor for type 2 ...
The Cleveland Clinic classified beta blockers into two categories, cardioselective and nonselective, according to its website. The latter is for medicines that block the B1 receptors found in the ...
Moxonidine is a new-generation alpha-2/imidazoline receptor agonist antihypertensive drug licensed for the treatment of mild to moderate essential hypertension. [5] [6] It may have a role when thiazides, beta-blockers, ACE inhibitors, and calcium channel blockers are not appropriate or have failed to control blood pressure.
Insulin resistance in Type 2 diabetes produces a greater demand for insulin production which results in the secretion of proinsulin. [29] ProIAPP is secreted simultaneously, however, the enzymes that convert these precursor molecules into insulin and IAPP, respectively, are not able to keep up with the high levels of secretion, ultimately ...
Type 1 diabetes is a disease caused by the lack of insulin. Thus, insulin is the main treatment agent for type 1 and is typically administered via subcutaneous injection. Type 2 diabetes is a disease of insulin resistance by cells. Type 2 diabetes is the most common type of diabetes.
In women with insulin resistance, such as those with polycystic ovary syndrome, androgen levels are often elevated. [184] Metformin, an insulin-sensitizing medication, has indirect antiandrogenic effects in such women, decreasing testosterone levels by as much as 50% secondary to its beneficial effects on insulin sensitivity. [184] [185] [186]
Beta-blockers act as competitive antagonists that block the effects of catecholamines at beta-adrenergic receptor sites, resulting in reduced rate and force of contraction of the heart, as well as reduced peripheral vascular resistance. [14] Non-selective beta-blockers: propranolol, nadolol, timolol; Beta-1-selective beta-blockers: atenolol ...
