How does insulin affect glucose levels?
The exogenously administered insulins exert their primary effect of lowering blood glucose levels via the promotion of glucose uptake into peripheral skeletal muscle and adipose tissue , the inhibition of glycogenolysis (the hydrolysis of glycogen to glucose), and the inhibition of gluconeogenesis (hepatic glucose production). Insulin also regulates fat metabolism by enhancing the storage of fat (lipogenesis) and inhibiting the mobilization of fat for energy in adipose tissues (lipolysis and free fatty acid oxidation). In addition, insulin regulates protein metabolism (through increasing protein synthesis and inhibiting proteolysis in muscle tissue). Biosynthetic insulins are used as replacement therapy in patients with Type 1 and Type 2 diabetes mellitus (DM) to restore their ability to properly metabolize carbohydrates, fats, and proteins. Insulin administration also facilitates the replenishment of liver glycogen stores.
Is insulin contraindicated for hypoglycemia?
Insulin is contraindicated during episodes of hypoglycemia. Patients at risk for hypoglycemia include those who are geriatric or who have brittle diabetes, have received an overdose of insulin, have a delayed or decreased food intake, or are undergoing an excessive amount of exercise relative to their usual insulin dose. Additionally, patients with renal impairment may be at increased risk of hypoglycemia.
Does angiotensin II antagonist affect insulin?
Angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists, and guanethidine may enhance the hypoglycemic effects of insulin. Patients should therefore be monitored closely for changes in glycemic control. [50223] [21961] [42591]
Can thiazide diuretics increase blood glucose levels?
Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazides on glucose control are dose-dependent and low doses can be used without significant effects. Patients on insulin therapy should be monitored for changes in blood glucose control. Insulin dosage adjustments may be necessary. [50223]
Can beta blockers cause hypoglycemia?
Beta-blockers can inhibit the compensatory actions of epinephrine's response to hypoglycemia. As such, hypoglycemia can be prolonged. Additionally, beta-blockers can mask the signs and symptoms of hypoglycemia, especially tachycardia. Beta-blockers have also been associated with increasing blood glucose concentrations. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes. [51005] Furthermore, their use should not be avoided in patients with compelling indications for beta-blocker therapy (i.e., post-MI, heart failure, etc.) when no other contraindications are present. Decreased mortality has been shown in the post-MI and heart failure populations when beta-blockers are used, especially in patients with coexisting diabetes mellitus. [50223]
Does insulin increase hypoglycemia?
The risk of hypoglycemia may increase with the use of insulin in combination with other antidiabetic agents such as alpha-glucosidase inhibitors, metformin, thiazolidinediones, or oral sulfonylureas. In addition, pioglitazone and troglitazone should be administered with caution as the combined use of insulin with these drugs significantly increases the risk of heart failure or edema.
How are insulins classified?
Insulins also are classified by the timing of their action in your body – specifically, how quickly they start to act, when they have a maximal effect and how long they act.Insulin analogs have been developed because human insulins have limitations when injected under the skin.
How Do Different Types Of Insulin Work?
Which insulin is right for you? The chart below will help you understand how the various insulin medications work and why your doctor has prescribed them for you. Insulin is injected into the fat tissue which helps it absorb into the bloodstream. Some insulin medications work faster than others, but don't last as long. And some insulins last longer but work more gradually than others. There are three characteristics that define types of insulin. Onset: How long it takes for the insulin to start lowering blood glucose Peak time: Time after injection when the insulin is the most effective at lowering blood glucose Duration: How long the insulin keeps lowering blood glucose Insulin is prescribed by matching the characteristics of a particular insulin with the individual needs of the patient . Some people are on only one kind of insulin, while others take a combination of insulin medication to customize good glucose control. There are six main types of insulin available: Rapid-acting: These include Apidra, Humalog, and Novolog. They have an onset in less than 15 minutes, peak in 30 to 90 minutes, and duration of three to five hours. Regular (short-acting): These include Humulin R and Novolin R. They have an onset of ahalf an hour to one hour, a peak of two to fourhours, and duration of three to five hours. Intermediate-acting: These include Humulin N and Novolin N. They have an onset of one to three hours, a peak of eight hours, and duration of 12 to 16 hours. Long-acting: These include Levemir an Lantus. They have an onset of one hour, minimal or no peak, and a duration of 2 Continue reading >>
How is insulin lispro produced?

What is the difference between insulin and insulin analogs?
Insulin analogs are now replacing human insulin in the US. Insulins are categorized by differences in onset, peak, duration, concentration, and route of delivery. Human Insulin and Insulin Analogs are available for insulin replacement therapy. Insulins also are classified by the timing of their action in your body – specifically, how quickly they start to act, when they have a maximal effect and how long they act.Insulin analogs have been developed because human insulins have limitations when injected under the skin. In high concentrations, such as in a vial or cartridge, human (and also animal insulin) clumps together. This clumping causes slow and unpredictable absorption from the subcutaneous tissue and a dose-dependent duration of action (i.e. the larger dose, the longer the effect or duration). In contrast, insulin analogs have a more predictable duration of action. The rapid acting insulin analogs work more quickly, and the long acting insulin analogs last longer and have a more even, “peakless” effect. Background Insulin has been available since 1925. It was initially extracted from beef and pork pancreases. In the early 1980’s, technology became available to produce human insulin synthetically. Synthetic human insulin has replaced beef and pork insulin in the US. And now, insulin analogs are replacing human insulin. Characteristics of Insulin Insulins are categorized by differences in: Onset (how quickly they act) Peak (how long it takes to achieve maximum impact) Duration (how long they last before they wear off) Concentration (Insulins sold in the U.S. have a concentration of 100 units per ml or U100. In other countries, additional concentrations are available. Note: If you purchase insulin abroad, be sure it is U100.) Route of delivery (whether they a Continue reading >>
What is the peptide that is cleaved into insulin?
