Pharmacodynamic and pharmacokinetic drug interactions Abstract. Drugs may interact with other drugs or any diet or dietary supplement taken at the same time. Interactions may be pharmacodynamic in which interaction is close to the target organ and involves direct antagonism or addition of pharmacological properties.rug interactions are usually described as pharmacodynamic (where changes in drug action occur in the area of the target tissue) or pharmacokinetic (when one drug affects the absorption, distribution or excretion of another).

Psychoactive drug An assortment of psychoactive drugs-street drugs and medications. A psychoactive drug, psychopharmaceutical, or psychotropic is a chemical substance that changes brain function and results in alterations in perception, mood, or consciousness.here are many ways in which psychoactive drugs can affect the brain. Each drug has a specific action on one or more neurotransmitter or neuroreceptor in the brain. Drugs that increase activity in particular neurotransmitter systems are called agonists.

Drowsiness, dizziness, constipation, flushing, nausea, nervousness, blurred vision, or dry mouth may occur. These effects usually lessen as your body gets used to the medicine. If any of these effects persist or worsen, contact your doctor or pharmacist promptly.

Pharmacodynamics Pharmacodynamics is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs). The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection). Pharmacodynamics is the study of how a drug affects an organism, whereas pharmacokinetics is the study of how the organism affects the drug. Both together influence dosing, benefit, and adverse effects.

BASIC PRINCIPLES OF PHARMACOLOGY Two Primary Branches of Pharmacology. The two major branches of pharmacology are: pharmacodynamics and pharmacokinetics. Pharmacodynamics-The study of the relationship between concentrations of drug and the biologic effects (physiological or biochemical) with time.In operational terms “what drugs do to the body”.xamples of multiple mechanisms for drug action include: chemical interactions with other molecules due to a drugs acidic or basic properties (e.g. antacids, or Protamine sulfate-a heparin antagonist), their ability to act as a membrane surfactant (amphotericin B), or their ability to denature proteins (astringents).

The goal of pharmacological therapy is to prevent motion sickness, or relieve the symptoms of motion sickness, such as nausea. Scopolamine, an anticholinergic, is used for the prevention of motion sickness and for acute treatment. Scopolamine’s effectiveness is likely due to its central anticholinergic properties.

Pharmacokinetics Pharmacokinetics, sometimes abbreviated as PK (from Ancient Greek pharmakon drug and kinetikos moving, putting in motion; see chemical kinetics), is a branch of pharmacology dedicated to determining the fate of substances administered externally to a living organism.harmacokinetics is often studied in conjunction with pharmacodynamics, the study of a drug's pharmacological effect on the body. A number of different models have been developed in order to simplify conceptualization of the many processes that take place in the interaction between an organism and a drug.

- Phencyclidine (PCP) Profile Phencyclidine (PCP) is a synthetic dissociative drug originally developed as a general anesthetic. The effects of dissociative drugs like PCP include feelings of detatchment from the environment and self.In its pure form, PCP is a white crystalline powder that dissolves easily in water or alcohol. As a liquid, it is clear, yellow, or tan and often is sold in vanilla extract bottles.CP’s Effects on the Brain PCP disrupts the functioning of receptors for the neurotransmitter glutamate, which plays a major role in the perception of pain as well as in learning, memory, and emotion. It also influences the actions of the neurotransmitter dopamine, which causes the euphoria associated with drug use.

Pharmacology Pharmacology is the branch of biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The fie

Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness..

Parasympathomimetic Drugs Also known as Cholinergic drugs or Cholinomimetic drugs or Cholinoceptor activating drugs. Definition. These are the group of drugs which produce effects resembling those produced by the stimulation of parasympathetic autonomic nervous system on the target organs. Neurotransmitter involved is acetylcholine. Most of the peripheral autonomic nervous system fibers cause synthesis and release of acetylcholine.
