Pharmacoepidemiology and Drug Safety
|February 7, 2002
Summary
Severe liver disease reports linked to troglitazone decreased over time. This decline in oral hypoglycemic agent hepatotoxicity may be due to enhanced monitoring and publicity.
Area of Science:
- Pharmacovigilance
- Hepatology
- Clinical Pharmacology
Background:
- Troglitazone, an oral hypoglycemic agent, was associated with severe liver injury.
- Understanding the trends in reported liver disease is crucial for patient safety.
Purpose of the Study:
- To analyze US rates of severe liver disease reported for troglitazone (March 1997-February 2000).
- To assess the impact of publicity on troglitazone hepatotoxicity reporting.
Main Methods:
- Utilized FDA and Parke-Davis reports of liver failure, jaundice, or hyperbilirubinemia.
- Calculated incidence rates based on patient and person-time exposure estimates.
- Quantified media and medical literature publicity regarding troglitazone hepatotoxicity.
Main Results:
- 83 cases of liver failure were reported; 59% were possibly or probably linked to troglitazone.
- Reported hepatic failure rates per 100,000 person-years decreased from 8.3 to 2.7 over three years.
- Publicity included 470 lay press and 158 medical literature articles on hepatotoxicity.
Conclusions:
- Reported severe liver disease rates declined significantly during troglitazone's marketing.
- This decline may be attributed to stricter monitoring and improved patient selection due to publicized hepatotoxicity risks.

Hormones Regulating Blood Glucose
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Oral Hypoglycemic Agents: Biguanides and Glitazones
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood glucose levels...
Oral Hypoglycemic Agents: Glinides
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively manages...
Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.

Glucagon-like Receptor Agonists
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...

Dipeptidyl Peptidase 4 Inhibitors
Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a significant...
