Oral Hypoglycemic Agents: Biguanides and Glitazones01:26

Oral Hypoglycemic Agents: Biguanides and Glitazones

212
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...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors01:19

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

185
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.
Acarbose and miglitol are...

Insulin: Dosing Regimen and Adverse Effects01:16

Insulin: Dosing Regimen and Adverse Effects

185
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...

Diabetes: Management and Pharmacotherapy01:15

Diabetes: Management and Pharmacotherapy

290
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Dipeptidyl Peptidase 4 Inhibitors01:23

Dipeptidyl Peptidase 4 Inhibitors

192
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...

Overview of Carbohydrate Metabolism01:19

Overview of Carbohydrate Metabolism

1.1K
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Summary
This summary is machine-generated.

Metformin incompliance is often due to gastrointestinal side effects and large tablet size. Compounded topical or liquid metformin formulations can improve patient compliance by mitigating these issues.

Area of Science:

  • Pharmaceutical Science
  • Clinical Pharmacy

Background:

  • Metformin incompliance is a significant challenge in diabetes management.
  • Common reasons for non-adherence include gastrointestinal side effects (nausea, diarrhea, abdominal pain) and the large size of oral tablets.
  • These factors negatively impact patient outcomes and therapeutic efficacy.

Purpose of the Study:

  • To explore alternative metformin formulations to improve patient compliance.
  • To address gastrointestinal side effects and swallowing difficulties associated with conventional metformin tablets.
  • To investigate the potential of compounded topical and oral liquid formulations.

Main Methods:

  • Review of existing literature on metformin formulations and patient compliance.
  • Discussion of compounding techniques for topical (transdermal) and oral liquid metformin.
  • Analysis of how these alternative formulations mitigate known issues.

Main Results:

  • Compounded topical metformin can bypass the gastrointestinal tract, eliminating associated side effects.
  • Transdermal delivery allows for potentially lower dosages compared to oral administration.
  • Oral liquid metformin formulations can resolve issues for patients with dysphagia or difficulty swallowing large tablets.
  • These alternative formulations directly address the primary reasons for metformin incompliance.

Conclusions:

  • Compounding pharmacists can create topical and oral liquid metformin formulations to enhance patient compliance.
  • These alternative delivery methods effectively manage gastrointestinal side effects and tablet size issues.
  • Optimizing metformin delivery through compounding offers a promising strategy for improved diabetes management.
