  2. Plateau principle - Wikipedia

    en.wikipedia.org/wiki/Plateau_Principle

    The plateau principle is a mathematical model or scientific law originally developed to explain the time course of drug action (pharmacokinetics). [1] The principle has wide applicability in pharmacology, physiology, nutrition, biochemistry, and system dynamics.

  3. Phases of clinical research - Wikipedia

    en.wikipedia.org/wiki/Phases_of_clinical_research

    The phases of clinical research are the stages in which scientists conduct experiments with a health intervention to obtain sufficient evidence for a process considered effective as a medical treatment. [1] For drug development, the clinical phases start with testing for drug safety in a few human subjects, then expand to many study ...

  4. Drug action - Wikipedia

    en.wikipedia.org/wiki/Drug_action

    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.

  5. Mechanism of action - Wikipedia

    en.wikipedia.org/wiki/Mechanism_of_action

    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.

  6. Course (medicine) - Wikipedia

    en.wikipedia.org/wiki/Course_(medicine)

    The course of a disease, also called its natural history, [3] is the development of the disease in a patient, including the sequence and speed of the stages and forms they take. [4] Typical courses of diseases include: chronic; recurrent or relapsing; subacute: somewhere between an acute and a chronic course

  7. Clinical trial - Wikipedia

    en.wikipedia.org/wiki/Clinical_trial

    Phase 0 trials are optional first-in-human trials. Single subtherapeutic doses of the study drug or treatment are given to a small number of subjects (typically 10 to 15) to gather preliminary data on the agent's pharmacodynamics (what the drug does to the body) and pharmacokinetics (what the body does to the drugs). [43]

  8. Liberation (pharmacology) - Wikipedia

    en.wikipedia.org/wiki/Liberation_(pharmacology)

    If a drug is administered in a form that is not rapidly dissolved, the drug will be absorbed more gradually over time and its action will have a longer duration. A consequence of this is that patients will comply more closely to a prescribed course of treatment, if the medication does not have to be taken as frequently.

  9. Pharmacokinetics - Wikipedia

    en.wikipedia.org/wiki/Pharmacokinetics

    Beta phase: A phase of gradual decrease in plasma concentration after the alpha phase. The decrease is primarily attributed to drug elimination, that is, metabolism and excretion. [10] Additional phases (gamma, delta, etc.) are sometimes seen. [11] A drug's characteristics make a clear distinction between tissues with high and low blood flow.
