1) discussing the symptoms for which PPI’s are prescribed and the intended target of these drugs. 2) address any organelle(s) that could also be affected by these drugs. 3) Based on the function of that organelle, do the issues in the research paper make biological sense? 4) Propose an alternative approach for patients with these symptoms that would not require them to remain on PPI’s long term. 5) Does this address the source of their symptoms? What is causing their...

Discuss the symptoms for which PPIs are prescribed and the intended target of these drugs. Next, address an organelle that would also be affected by these drugs. Based on the function of that organelle, do the issues in the website make biological sense? Lastly, propose an alternative approach for a patient with these symptoms that would not require him or her to remain on PPIs long-term. Does your approach address the source of their symptoms?

Tetrodotoxin and lidocaine are both drugs that cause local analgesia or numbness where applied to the skin. Explain this outcome, with reference to the effects on membrane potentials, ion flux and overall neuronal activity. Would you predict that these drugs could affect other neurons than just those mediating cutaneous sensation? If so, how? If not, why not?
