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.
A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor. [3] Receptor sites have specific affinities for drugs based on the chemical structure of the drug, as well as the specific action that occurs there.
take (often effectively a noun meaning "prescription"—medical prescription or prescription drug) rep. repetatur: let it be repeated s. signa: write (write on the label) s.a. secundum artem: according to the art (accepted practice or best practice) SC subcutaneous "SC" can be mistaken for "SL," meaning sublingual.

The mechanism of action is a crucial factor in determining effect and toxicity of the drug, taking in consideration the pharmacokinetic (PK) factors. [12] The sort and extent of altered cellular physiology will depend on the combination of the drug's presence (as established by pharmacokinetic (PK) studies) and/or its mechanism and duration of ...
The topology of a biochemical reaction network determines the shape of drug dose-response curve [42] as well as the type of drug-drug interactions, [43] thus can help designing efficient and safe therapeutic strategies. The topology Network pharmacology utilizes computational tools and network analysis algorithms to identify drug targets ...
Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
It concluded that both drugs helped improve attention, inhibition, and reaction time. In addition, people using methylphenidate also demonstrated improvements in working memory.
The IUPHAR/BPS Guide to PHARMACOLOGY is an open-access website, acting as a portal to information on the biological targets of licensed drugs and other small molecules. The Guide to PHARMACOLOGY (with GtoPdb being the standard abbreviation) is developed as a joint venture between the International Union of Basic and Clinical Pharmacology (IUPHAR) and the British Pharmacological Society (BPS).
