Cholinergic and Cholinesterase Inhibitors
| Question | Answer |
|---|---|
| What receptor does the direct acting Cholinergic agonist use? | Muscarinic |
| What receptor does the indirect acting Cholinergic agonist or AChEI use? | Nicotinic |
| What chemical substances make up direct acting cholinergic drugs? | Naturally occuring alkaloids, or synthetic choline esters |
| What chemical characteristics make up indirect acting and/or AChEI's, what doe they do? | They can be reversible or irreversible, they increase ACh concentrations |
| The M1 muscarinic receptor, location and secondary messenger? | Nerves/CNS and and increase in IP3 and DAG - through Gq |
| The M3 muscarinic receptor, location and secondary messenger? | Eyes,glands,smooth muscle and endothelium(blood vessels) and increase in IP3 and DAG - through Gq |
| The M2 muscarininc receptor, location and secondary messenger? | Found in the heart(vagal effect), nerves - reduces AC which reduces cAMP, opens up K channels in heart |
