It also causes a negative dromotropic effect through the inhibition of AV-nodal conduction. [20] From the 1980s onwards, these effects of adenosine have been used in the treatment of patients with supraventricular tachycardia. [21] The regulation of vascular tone in the endothelium of blood vessels is mediated by purinergic signalling.
The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection). Pharmacodynamics and pharmacokinetics are the main branches of pharmacology , being itself a topic of biology interested in the study of the interactions of both endogenous and exogenous chemical ...

The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
Pharmacology can also focus on specific systems comprising the body. Divisions related to bodily systems study the effects of drugs in different systems of the body. These include neuropharmacology, in the central and peripheral nervous systems; immunopharmacology in the immune system.
Police have yet to determine the body's identity or if the cause of death was an alligator attack, but the body's state of decomposition has led police to think its been in the water for over a day.
