Neurotransmitters, drugs mimicking

Agonist drugs can also bind directly to the postsynaptic receptor, so mimicking the physiological effect of the neurotransmitter for example, morphine and heroin bind to the brain s opiate receptors and, thus, directly stimulate feelings of pleasure and pain... 

Opiate drugs encompass morphine and its many synthetic derivatives including heroin. Opiates act by mimicking endogenously occurring morphine-like neurotransmitter peptides termed the enkephalins or endorphins. 

Conditions mimicking MDD can occur secondary to a wide variety of prescribed and illicit agents. With some drugs, the syndrome occurs as a direct and immediate effect. For example, some antihypertensive agents (e.g., reserpine, a-methyidopa) acutely antagonize central biogenic amine neurotransmitter systems. 

Remember, the primary job of the neurotransmitter is to fit or lock into its own particular receptor, and then to initiate specific physiological responses within the body. However, many drugs, such as THC, are able to bind or attach themselves to a specific receptor, thus mimicking or blocking the normal... 

Receptor activation. A drug may activate a receptor site by mimicking a neurotransmitter.
