Abstract

Insights

Suppressing insulin secretion may help reduce body weight and fat mass in obese individuals. This approach led to significant weight loss but a slight increase in blood glucose levels.

Area of Science:

  • Endocrinology and Metabolism
  • Pharmacology
  • Obesity Research

Background:

  • Obesity is a complex metabolic disorder with significant health implications.
  • Current obesity treatments have varying efficacy and safety profiles.
  • Targeting insulin secretion presents a potential therapeutic avenue for weight management.

Purpose of the Study:

  • To evaluate the efficacy and safety of suppressing insulin secretion for obesity treatment.
  • To synthesize evidence from randomized controlled trials on drugs that directly suppress insulin secretion.

Main Methods:

  • Systematic literature search of PubMed, Embase, and Cochrane databases up to January 1, 2020.
  • Inclusion of randomized controlled trials using diazoxide or octreotide to suppress insulin secretion.
  • Meta-analysis of extracted data using random-effects models.

Main Results:

  • Seven trials were included (4 diazoxide, 3 octreotide).
  • Insulin suppression significantly reduced fasting insulin but slightly increased fasting blood glucose.
  • Significant reductions in body weight, BMI, and fat mass were observed compared to placebo.

Conclusions:

  • Suppression of insulin secretion shows potential for reducing body weight and fat mass in obesity.
  • This intervention may lead to a slight increase in blood glucose levels.
  • Further research is warranted to confirm safety and long-term efficacy.

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...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution01:25

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Glucagon-like Receptor Agonists01:24

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...

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Dipeptidyl Peptidase 4 Inhibitors01:23

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...
