Introduction to Pharmacology - Insulin
Pharmacology - Insulin is designed to provide an in-depth understanding of insulin, a crucial hormone for glucose regulation within the body. This field explores the physiological insulin secretion from beta cells in Langerhans islets, detailing the molecular weight, amino acid composition, and the role of zinc and C-peptide in insulin's function. It covers the regulation of insulin secretion by various nutrients, hormones, and neurotransmitters, and addresses the impact of inhibitory signals and drugs on insulin levels. The importance of insulin in promoting the storage of fat and glucose, influencing cell growth, and managing the metabolic functions of different tissues is emphasized. Examples include the use of insulin preparations like zinc+insulin crystals for treating diabetes, and the examination of insulin's role in glucose uptake through GLUT 4, highlighting its critical function in medical pharmacology.

Main Functions of Pharmacology - Insulin
Regulation of Insulin Secretion
ExampleInsulin secretion is intricately regulated by nutrients (e.g., glucose, amino acids), gastrointestinal hormones (GIP, GLP-1), pancreatic hormones, and autonomic neurotransmitters. This ensures a balanced insulin level in response to physiological needs.
ScenarioIn diabetes management, understanding the regulatory mechanisms helps in optimizing insulin therapy, especially in type I diabetes where exogenous insulin is vital for survival.
Insulin's Anabolic Actions
ExampleInsulin's anabolic actions include promoting glucose and fat storage, enhancing protein synthesis, and influencing cell growth and division by activating transcription factors.
ScenarioThese actions are critical in maintaining energy balance and are leveraged in metabolic syndrome treatments and managing insulin resistance scenarios.
Pharmacokinetics of Insulin Preparations
ExampleThe pharmacokinetics of various insulin preparations, such as rapid-acting (e.g., Insulin lispro, aspart, glulisine) and long-acting (e.g., Insulin glargine, detemir) insulins, are studied to match insulin action with physiological needs.
ScenarioIn diabetes management, selecting the appropriate insulin preparation and understanding its onset, peak, and duration of action are crucial for achieving optimal glycemic control.

Pharmacology - Insulin Q&A
What types of insulin are there?
There are several types of insulin, classified based on their duration of action: rapid-acting, short-acting, intermediate-acting, long-acting, and ultra-long-acting. Each type mimics the body's natural insulin timing to various extents.
How do I store insulin properly?
Insulin should be stored in a refrigerator at 2 to 8 degrees Celsius. Avoid freezing it or exposing it to direct heat or light. Opened insulin can generally be kept at room temperature for up to a month.
Can insulin be used for conditions other than diabetes?
While primarily used to treat diabetes, insulin also has investigational uses in treating acute potassium overdose by shifting potassium into cells, and some researchers are exploring its potential anti-inflammatory effects.
What are the common side effects of insulin?
Common side effects include hypoglycemia, weight gain, and local allergic reactions at the injection site. Long-term use can lead to insulin resistance and sometimes lipodystrophy at the injection site.
How do insulin pumps work?
Insulin pumps deliver continuous subcutaneous insulin infusion, providing a steady dose of rapid-acting insulin throughout the day and additional doses (boluses) tailored to meal intake, significantly improving blood glucose management.
