This is a draft cheat sheet. It is a work in progress and is not finished yet.

Reversible anti-c­hol­ine­sterase

Physos­tigmine
Neosti­gmine
Pyrido­sti­gmine
Ambeno­noium Cl
Edroph­onuim Cl
Donepe­zil­"Aricept"
ttt of glaucome
ttt of myasthenia gravis
ttt of myasthenia gravis
ttt of myesthenia gravis
 
ttt of Alzhei­mer's' dimentia
Antidote to atropine poisoning.
-Natural
   
longer duration
Can pass BBB & conjun­ctiva
   
fewer GI side effects
 
Side effects include nausea, diarrhea, sleeping troubles
(indirect cholin­omi­metics)

Muscarinic agonist

-Betha­nechol Cl-
must not be admini­stered IV or IM routes
Used for urine retention or abdominal distention (to increase digest­ion).
Long acting due to:
1. Beta methyl
2. Carbamate ester

Irreve­rsible ChE inhibi­tors.

Organo­pho­sphorus compounds: insect­icide, nerve gases & ttt of glaucoma.
Antidote: Pralid­oxime (ChE reacti­vator)
Tetraethyl pyroph­osphate

Anti-m­usc­arinic

Natural
Synthetic (amino­-al­coh­ol-­ester)
Synthetic (amino­-al­cohol)
Solana­ceous alk. (Atropine & scopol­amine)
Clidinium bromide
Biperiden
atropine is used as preane­sthtic to decrease oral and pulmonary secret­ions.
Used in ttt of spastic colon and peptic ulcer.
Anti-p­ark­ins­onian
 
-It's combined with chlord­iaz­eop­oxide in a drug called Normaxin
Combined with levodopa
 
Its anti-s­pas­modic and anti-s­ecr­etory so decreases gastic HCl secretions and abdominal cramping.
CI in glaucoma
Contra­ind­icated with glaucoma
 

(Depol­ari­zing) Ganglionic blockers

Nicotine
Acts as a blocker only in large doses (small doses of nicotine are stimul­ants)

Non-de­pol­arizing neurom­uscular blockers

Tubocu­rarine
Gallamine trieth­iodide
Pancur­onuim
Rocuronuim bromide
-natural-
Synthetic
Aminos­teroid ms. relaxant
Aminos­teroid ms. relexant
 
muscle relaxant for surgical procedures
Used for euthan­sia­/lethal injection
Used as skeletal ms relexant, usually for endotr­acheal intubation (mecha­nical ventil­ation or surgery)
   
Effects are partially reversed by reversible ChE inhibi­tors.
Also called curariform or curari­-mi­mmetic drugs.
They relax smooth ms. and used as preane­sthetic medica­tion.
They must have quaternary ammonium compounds to have a permanent positive charge so that they never act centrally (never pass BB).
