Step by step
Solved in 2 steps
- Which drug is afull agonist at opioid receptors with analgesics activitiy equivalent to morphine, a linger duration of action and fewer with drawal sign on abrupt discontinuance than morphine?? 1-fentanyl 2-methadone 3- NalbuphineThe rewarding or reinforcing effects of amphetamines, cocaine, and heroin have been associatedwith the effect on which major neurotransmitter?A.acetylcholineB.GABAC.dopamineD.serotoninGive 2 examples of drugs which target neurotransmitter release or reuptake.(expect from cocaine and Prozac). Explain the mechanisms of action.
- Before LTP: In the normal state, what is the effect of glutamate at the AMPA receptors? At the NMDA receptors?Briefly describe the proposed mechanism of CNS depression by benzodiazepines. Give examples of most commonly used benzodiazepines. What side effects or clinical problems have to be monitored?If given the choice of treating Parkinson’s disease pharmacologically with L-Dopa or invasively using deep brain stimulation which option would you pick and why? (
- In schizophrenia, the neurons affected by dopamine are overstimulated. This condition is treated with drugs like chlorpromazine (Thorazine), which bind to the affected receptors and inhibit the dopamine signal. Does chlorpromazineact as an agonist or antagonist?In cholinergic neurotransmission, inhibition of the choline transporter will affect the normal synthesis and release acetylcholineTRUE OR FALSEWhy morphine show less analgesic activity after oral administration? Briefly explain at your own words Answer need.
- Discuss how benzodiazepines affect the balance between the excitation and inhibition in the brain, taking into consideration their mechanism of action.Why morphine show less analgesic activity after oral administration? Briefly explain at your own wordsWhat is the structue of dopamin, and suggest the binding interactions of dopamine with the receptor. Draw a suggested model for the required interactions for agonistic and antagonistic activty in dopamine receptor.
