Pancreatin is preferred over pancrelipase for enzyme replacement.

Pancrelipase capsules should be chewed to aid absorption.

Ursodiol is effective for dissolving non-calcified cholesterol gallstones.

Ursodiol therapy typically dissolves gallstones within 2 to 3 weeks.

Ursodiol is associated with hepatotoxicity.

Octreotide acts by increasing portal venous pressure.

Octreotide is used as first-line therapy in esophageal variceal bleeding.

Vasopressin causes vasodilation of splanchnic circulation.

The adverse effects of vasopressin include myocardial ischemia and mesenteric infarction.

Beta-blockers like propranolol reduce portal pressure via alpha-1 receptor blockade.

Propranolol reduces cardiac output by blocking beta-1 receptors.

N-acetylcysteine acts by binding directly to acetaminophen.

N-acetylcysteine replenishes glutathione levels in the liver.

High doses of pancrelipase can cause renal stones due to purine content.

Pancrelipase must be taken on an empty stomach for best effect.

Terlipressin is a vasopressin analogue with fewer adverse effects.

Bile acid therapy is suitable for large calcified gallstones.

Octreotide may cause gallbladder sludge and hyperglycemia.

N-acetylcysteine should be avoided in acetaminophen overdose.
