Definition
Indirect sympathomimetic- converted to octopamine, an inert/false transmitter. Can cause hypertension.
Term
Ephedrine
Definition
'Amphetamine-like' Indirectly releases NE, direct Beta-2 agonist and alpha-1 agonist. Anorexigenic
Term
Pseudoephedrine
Definition
"Amphetamine like", lacks direct Beta-2 agonist action. Indirectly acts as a nasal decongestant. Has less CNS stimulation than ephedrine.
Term

Definition
Both 'D' and 'L' isomers. Act the same in the periphery to indirectly release NE. In CNS D isomer is 3-4x more potent. Releases DA to stimulate CNS.
Term
MDMA
Definition
'Ectasy' - can cause hyperthermia
Term
Methamphetamine
Definition
Last longer than cocaine, shorter than amphetamine
Term
Cocaine
Definition
'Amphetamine like'. Local anesthetic, and vasoconstricter. Blocks NE reuptake in periphery and DA reuptake in CNS.
