Cocaine has two effects on synaptic transmission and is classified as an agonist.
Further Explanation:
Agonists are chemicals that generally mimic the neurotransmitter at a site of the receptor. On the other hand, antagonists are referred to as a chemical that impedes or blocks the normal functioning of the neurotransmitter at the site of the receptor. Cocaine is a drug that causes a large number of neurotransmitters to stay in the synapse for a very long period of time. They bind to the transporter protein present on the presynaptic membrane that removes dopamine from the synaptic cleft. Then, eventually,dopamine remains in the cleft and repeatedly stimulates the receptors. Exposure to a constant chemical stimulus for a prolonged period affects brain receptors. The stimulation experienced by the brain is decreased and gradually, there is a complete loss of the stimulus. <u>Cocaine </u><u>is considered as an </u><u>agonist </u>this is because by inhibiting the enzymatic degradation of neurotransmitters, it rises the probable time that these “neurotransmitters” may be active in the synapse.
