Document Summary
Glutamate is excitatory = not a hard and fast rule. Gaba is inhibitory = not a hard and fast rule. Both of these are considered to have these effects because the majority is. Heroin more addictive because it as a faster effect. The faster drugs cross the blood-brain barrier, the more addictive it is. Oral consumption or drugs has slower effects because it gets into the blood much slower. Intramuscular injection: slow because the drug is stuck in the muscles. Sublingual administration: absorbed through the blood in the capillaries there. Intracerebral administration: when drugs are unable to go through the blood-brain barrier and the researchers don"t have a specific destination for it. Intracerebroventricular: when drugs are unable to go through the blood-brain barrier. Dose response curve: when creating a safety profile. If drug has multiple effects, the drug will have multiple curves.
