Q

How are H2 r antagonists eliminated?

A

Renal excretion

17
Q

What does renal impairment require in terms of H2 r antagonist therapy?

A

Dose reduction

18
Q

Which H2 r antagonist has most extensive side effects?

A

Cimitidine

19
Q

Are antimuscarinics useful for isolated acid reduction?

A

They are rarely used due to side effects

20
Q

Sucralfate is a

A

Mucosal binding agent that binds preferentially to the ulcer, and has no acid-neutralizing effects

21
Q

Subgallate is a

A

Mucosal protective agent with weak acid neutralizing capacity

22
Q

Subcitrate is a

A

Mucosal protective agent with weak acid neutralizing capacity

23
Q

Subnitrate is a

A

Mucosal protective agent with weak acid neutralizing capacity

24
Subsalicylate is a
Mucosal protective agent with weak acid neutralizing capacity
25
What do mucosal protective agents do?
Increase mucous secretion, thus coating ulcer, also cause detachment of H. Pylori
26
Sucralfate side effects?
Dry mouth, constipation
27
Sucralfate interferes with what drugs?
Tetracycline, phenytoin, digoxin, and cimetidine
28
Misprostol is a
Mucosal protective agent
29
Misprostol is used how often for ulcers? Why?
Rarely, due to side effects. Works as a PGE1 analogue, and there are tons of receptors for dat crap. Only good for NSAID-induced ulcers, and we don't even really use it for that.
30
Antacid MOA?
Bases neutralize acid in stomach, increase pH.
31
Antacid effectiveness compared to H2 r blockers?
About the same
32
Antacid side effects?
Alkaluria--> Kidney stones Maybe Na+ content too high for CHF pts Lots of drug interaction effects
33
Sodium Bicarbonate is a
An antacid
34
Calcium carbonate is a
An antacid
35
Calcium carbonate causes
Hypercalcemia and rebound HCl secretion
36
Milk of magnesia is a
An antacid
37
Milk of magnesia causes
Blood Mg increase, osmotic effects, increased intestinal motility
38
Aluminum compounds cause
Constipation
39
What two antacids may be mixed to counter side effects?
