The study of drugs that effect a person's thinking, behaviors or emotions.
4 areas of social work knowledge/ practice impacted by pharmocology
1) Understanding- the effectiveness of medications in symptom reduction. 2) Monitoring- physical, psychological, and social side effects/ consequences. 3) Educating clients/ families about physical and psychological adjustments. 4) Communicating with physicians and pharmacists.
Entirely devoted to processing visual input.
Areas of the brain targeted by psychotropic medications
never pathways involved in thinking and feeling. Many other Brain areas.
Parietal Lobes (L.I.S)
Involved in Long-term memory, info processing, and receive sensory information from the body (L.I.S).
Temporal Lobes (H.P.S)
Hearing, Perception, and storage of memory (H.P.S).
Basic Functions of the Brain (R.D.I)
Receive- info from outside. Decide- use the information to decided on a response. Implement- send commands to various muscles and glads to enact a response.
Important center of learning. Converts information from short term to long term memory.
Located in the midbrain
Helps regulate movement.
Site at which dopamine is depleted in Parkinson's disease.
Motivational and addictive behavior.
Connects the cerebral cortex to other parts of the brain.
Impacted by stimulants.
Located on both sides of the Limbic system/ brain.
7 processes of Neurotransmitters: Step 1.
Neurotransmitter molecules are synthesized from precursors with the help of enzymes.
7 processes of Neurotransmitters: Step 2
Neurotransmitter molecules are stored in vesicles.
7 processes of Neurotransmitters: Step 3
Neurotransmitter molecules the leak from vesicles are destroyed by enzymes.
7 processes of Neurotransmitters: Step 4
Action potentials cause vesicles to fuse with the pre-synaptic membrane and release neurotransmitters into the synapse.
7 processes of Neurotransmitters: Step 5
Neurotransmitters bind with auto-receptors and inhibit neurotransmitter release.
7 processes of Neurotransmitters: Step 6.
Neurotransmitters bind with the post-synaptic receptors.
7 processes of Neurotransmitters: Step 7
Neurotransmitter molecules are deactivated either by reuptake or made into waste (degradation).
Study of how the human body responds to drugs.
One reason why pharmacokinetics is important
It helps explain why some people respond differently to the same drugs
4 bodily processes involved in pharmacokinetics
Process by which the drug enters the blood stream. Typically through the bowel walls.
How a drug travels to the desired sight (the brain for psychotropic drugs). Most commonly by dissolving in the blood plasma or becoming attached to plasma proteins.
Is how the body breaks down the drug. Usually done by liver enzymes; molecules are altered from lipid-soluble substances into water-soluble salts, making theme easier to excrete.
How the drug is eliminated from the body by both metabolism and excretion, which lower the concentration of a drug in the body.
