Show Answers:

  1. which group has the best activity for B-agonists
    primary and secondary nitrogen
  2. what does a large R1 confer for b agonist
    B selectivity
  3. what is the result of the substitution of alkyl chain linking Ar to N
    decreases MAO metabolism

    MAO and COMT metabolism
  8. with the long acting B2 agonist, what are the long side chains serve for
    anchor drug at receptor site
  9. ipratropium bromide is similar to what anticholinergic
  10. what is ipratropium classified as
    an amino alcohol ester
  11. how is ipratropium metabolized
    by hydrolysis then excretion
  12. tiotropium is related to which drug
  13. tiotropiums long DOA is due to what
    slower hydrolysis
  14. how is tiotropium administered
    as an inhaled powder
  15. what do glucocorticoids regulate
    • glucose metabolism
    • modulate inflammation
  16. how do fluorines affect glucocorticoids
    they increase their activity
  17. how do acetal/ketals affect mineralocorticoids
    they decrease the activity
  18. lipophilicity compared of mineralocorticoids compared to glucocorticoids
    mineralocorticoids are more lipophilic than glucocorticoids
  19. what are mast cell stabilizers NOT compatible with
    salts of basic drugs such as atropine HCl
