An antagonistic drug
|
|
The term __________ generally refers to drug taking that causes emotional or physical harm to oneself or others. The drug consumption is also typically compulsive, frequent, and intense.
|
Drug abuse
|
|
A broad term referring to a condition in which a person feels compelled to use a specific drug. People now use the term to describe almost any type of compulsive activity, from working to surfing the Internet.
|
Addiction
|
|
Steps in which agonistic drugs produce their psychoactive effect.
|
1.) Agonistic drugs increase neuron's ability to synthesize more transmitter molecules, store them more securely, or release them.
2.) Agonistic drugs and some neurotransmitters have similar shapes. Drug binds with the receptor sites and mimics the neurotransmitter's message. 3.) Agonistic drugs block the deactivation of excess neurotransmitters by preventing reuptake or degradation. This blockage allows excess neurotransmitter molecules to remain in the synapse and thereby prolong activation of the receptor site. |
|
Steps in which antagonistic drugs produce their psychoactive effect.
|
1.) Antagonistic drugs decrease neuron's ability to synthesize, store, and release neurotransmitters.
2.) Antagonistic drugs bind with the receptor sites. However, the molecular shape of the drug is dissimilar enough to the neurotransmitter that its message is blocked. |
