Study Notes
Pancreas Function
- Located in the abdomen, essential for converting food into fuel for the body's cells.
- Exocrine function:
- Converts food into energy.
- Releases digestive enzymes, including trypsin and chymotrypsin (protein digestion) and amylase (carbohydrate digestion).
- Endocrine function:
- Regulates blood sugar levels.
- Insulin produced by alpha cells, glucagon produced by beta cells.
Pancreatitis Overview
-
Acute pancreatitis:
- Inflammatory disorder characterized by upper abdominal pain and elevated pancreatic enzymes.
- Common causes include gallstones and alcohol abuse.
- Associated with conditions like diabetes and autoimmune disorders; can be idiopathic (no identifiable cause).
-
Chronic pancreatitis:
- Progressive disease with long-term inflammation leading to loss of exocrine and endocrine function.
Drug-Induced Pancreatitis
- Well-supported associations:
- Cimetidine, Enalapril, Erythromycin, Furosemide.
- Probable associations:
- Acetaminophen, Atorvastatin, Ifosfamide, Methyldopa, Hydrochlorothiazide, Simvastatin, Cisplatin, Oxaliplatin.
- Mechanism of action:
- Acute pancreatitis initiated by premature activation of trypsinogen to trypsin, causing autodigestion of pancreas.
- Damaged pancreatic tissue leads to surrounding fat and vascular endothelium necrosis, with lipase damaging fat cells producing inflammatory byproducts.
Key Drug Information
- Atorvastatin and Simvastatin: HMG-CoA reductase inhibitors, used to lower cholesterol.
- Cimetidine: H2 receptor antagonist, reduces gastric acid secretion.
- Enalapril: ACE inhibitor, used to treat hypertension.
- Erythromycin: Macrolide antibiotic, used for bacterial infection treatment.
- Furosemide: High ceiling diuretic, acts on renal system.
- Hydrochlorothiazide: Thiazide diuretic, acts on distal convoluted tubule.
- Cisplatin and Oxaliplatin: Platinum compounds used in chemotherapy.
- Methyldopa: Drug of choice for hypertension in pregnant women.
- Tamoxifen: Commonly used in breast cancer treatment.
- Sulindac: Non-steroidal anti-inflammatory drug (NSAID).
