Abstract:
The aim of the study was to evaluate the influence ofnonsteroidal anti-inflammatory drugs on deaminase adenosine activity using animal model. 70 rats of Wistar breed was divided into equal groups of ten. Animals were given intragastrically for three weeks: acetylsalicylic acid (ASA) at doses of 2 and 10 mg/kg bw/day, diclofenac at doses of 1 and 5 mg/kg bw/day, nimesulide at doses of 2.5 mg and 12.5 mg/kg bw/day. Control group received only water. After 21 days rats were decapitated and blood was collected to assess deaminase adenosine activity in plasma and erythrocytes. It was found that all investigated drugs inhibit ADA activity in plasma and ADA2 isoenzyme is responsible for this inhibition. Deaminase adenosine activity in erythrocytes is inhibited by ASA and diclofenac but increased by nimesulide.

α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...

α1-blockers: These drugs inhibit α1-adrenoceptors on smooth muscle cells, resulting in vasodilation. This vasodilation lowers blood pressure, making α1-blockers valuable in treating hypertension. Additionally, α1-blockers effectively address urinary obstruction...

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
