A

Pilocarpine

4

A

Methacholine by bronchoconstriction

5
Q

What drug has DOA of 1 hour, is used locally for glaucoma, and has little to no side effects when used locally?

Organophosphates

7
Q

What category of indirect acting cholinergic drugs are reversible and water soluble?

A

Carbamates

8
Q

What do Physostigmine, neostigmine, pyridostigmine, edrophonium, tacrine, donepezil, rivastigmine, galantamin have in common?

A

They are carbamates that inhibit acetylcholinesterase and block its active site. They are hydrolyzed within 2-8 hours

9

A

Echothiophate

10
Q

What 5 drugs are used as weapons of mass destruction?

A

Physostigmine

12
Q

A

Neostigmine, Pyridostigmine, Edrophonium

13
Q

What drug amplifies the effects of Ach by stopping its breakdown temporarily?

A

Physostigmine

14
Q

What 2 drugs amplify effects of Ach and treat glaucoma?

A

Isoflurophate, Echothiophate

15
Q

What are two antidotes for indirect acting cholinergic drugs?

A

Atropine and pralidoxime

16
Q

How does pralidoxime work as an antidote?

A

cholinesterase reactivator (breaks bond between drug and un-aged cholinesterase)

17
Q

How does atropine work as an antidote?

A

antimuscarinic; reduces the effects of Ach at muscarinic site

A

Benztropine

19
Q

What muscarinic antagonist drug works on GU to treat transient cystitis and postoperative bladder spasms?

A

Oxybutinin

20
