Physostigmine kinetic and uses |
Kinetics - rapidly absorbed from git and parenteral routes.. Crosses cornea and bbb easily |
|
|
|
Pyridostigmine |
Similar to neostigmine but longer acting and less potent.. Thus more tolerant by mg patients and preferred more |
|
|
|
Edrophonium uses |
1 diagnosis of mg - ameliorative test 2 differentiate bw myastenia and cholinergic crisis 3 preferred in curare poisoning bcoz of its rapid onset of action |
|
|
|

|
|

|
|
Compare physostigmine and neostigmine |
As neostigmine has structure similar to ach, it directly acts at Nm receptors of NMJ and thus improve muscle power in patients of myastenia gravis |
As neostigmine has structure similar to ach, it directly acts at Nm receptors of NMJ and thus improve muscle power in patients of myastenia gravis |
