Know About Humulin N (nph) Insulin Onset, Peak Time And Duration

What is Humulin N? It is a human insulin that is used to treat diabetes mellitus in both adults and children. Insulin is a natural hormone that is produced by the beta cells in the pancreas. This hormone works by helping glucose enter cells that can convert it into energy. Without insulin, glucose stays in the bloodstream. People with diabetes cannot make enough insulin or they become resistant to it. Because of this, they experience high blood sugar levels. If left untreated, high blood sugar levels can lead to health complications such as nerve or kidney damage. This is where Humulin N comes in. This man-made insulin works similarly to the natural hormone that is produced in the body. Humulin N is produced after combining protamine sulfate and human insulin under the right condition so that crystals can be formed. When this solution is injected subcutaneously, it helps to control blood sugar levels. This medication is part of a treatment program that also includes exercise, diet, weight control, and testing blood glucose regularly. Humulin N (NPH) insulin onset, peak time and duration Humulin N is intermediate acting insulin that is administered using an injection pen or syringe. After injection under the skin, the drug starts to work slowly and the effects can last up to 18 hours. Humulin N onset refers to how fast this insulin starts to work to reduce blood sugar levels. Humulin N peak is the time it takes before the maximum effects are felt. This medication has an onset time of 2 to 4 hours. The peak time of this medication is between 4 to 12 hours. This drug can cover your insulin needs for half a day or overnight. Intermediate acting insulin, such as Humulin N, can be taken together with short or rapid acting insulin. How to inject Humulin N is injected subcutane Continue reading >>

Insulin Chart

List of insulin types available in the U.S. and how they work. By the dLife Editors Each type of insulin has its own unique behavior. One difference among types of insulin is how long they take to start working at lowering blood-glucose levels. The “insulin peak” is the point at which the dose is working at its maximum, and the “duration” is how long the blood-glucose-lowering effect of the injection will last. The following is a list of insulin types available in the United States, along with how soon they start working, their peak, and how long they last. Talk to your healthcare provider about your insulin regimen. Insulin Type Onset of Action Peak Duration of Action Lispro U-100 (Humalog) Approximately 15 minutes 1-2 hours 3-6 hours Lispro U-200 (Humalog 200) Approximately 15 minutes 1-2 hours 3-6 hours Aspart (Novolog) Approximately 15 minutes 1-2 hours 3-6 hours Glulisine (Apidra) Approximately 20 minutes 1-2 hours 3-6 hours Regular U-100 (Novolin R, Humulin R) 30-60 minutes 2-4 hours 6-10 hours Humulin R Regular U-500 30-60 minutes 2-4 hours Up to 24 hours NPH (Novolin N, Humulin N, ReliOn) 2-4 hours 4-8 hours 10-18 hours Glargine U-100 (Lantus) 1-2 hours Minimal Up to 24 hours Glargine U-100 (Basaglar) 1-2 hours Minimal Up to 24 hours Glargine U-300 (Toujeo) 6 hours No significant peak 24-36 hours Detemir (Levemir) 1-2 hours Minimal** Up to 24 hours** Degludec U-100 & U-200 (Tresiba) 1-4 hours No significant peak About 42 hours Afrezza < 15 minutes Approx. 50 minutes 2-3 hours *Information derived from a combination of manufacturer’s prescribing information, online professional literature sources and clinical studies.

5 Types Of Insulin And How They Work

5 Types Of Insulin And How They Work

What you need to know If you have to take insulin to treat diabetes, there’s good news: You have choices. There are five types of insulin. They vary by onset (how soon they start to work), peak (how long they take to kick into full effect) and duration (how long they stay in your body). You may have to take more than one type of insulin, and these needs may change over time (and can vary depending on your type of diabetes). Find out more about the insulin types best for you. Rapid-acting insulin What it’s called: Humalog (lispro), NovoLog (aspart), Apidra (glulisine) Rapid-acting insulin is taken just before or after meals, to control spikes in blood sugar. This type is typically used in addition to a longer-acting insulin. It often works in 15 minutes, peaks between 30 and 90 minutes, and lasts 3 to 5 hours. “You can take it a few minutes before eating or as you sit down to eat, and it starts to work very quickly,” says Manisha Chandalia, MD, director of the Stark Diabetes Center at the University of Texas Medical Branch, in Galveston. Short-acting insulin What it’s called: Humulin R, Novolin R Short-acting insulin covers your insulin needs during meals. It is taken about 30 minutes to an hour before a meal to help control blood sugar levels. This type of insulin takes effect in about 30 minutes to one hour, and peaks after two to four hours. Its effects tend to last about five to eight hours. “The biggest advantage of short-acting insulin is that you don't have to take it at each meal. You can take it at breakfast and supper and still have good control because it lasts a little longer,” Dr. Chandalia says. Intermediate-acting insulin What it’s called: Humulin N (NPH), Novolin N (NPH) Intermediate-acting insulin can control blood sugar levels for about Continue reading >>

Types Of Insulin For Diabetes Treatment

Types Of Insulin For Diabetes Treatment

Many forms of insulin treat diabetes. They're grouped by how fast they start to work and how long their effects last. The types of insulin include: Rapid-acting Short-acting Intermediate-acting Long-acting Pre-mixed What Type of Insulin Is Best for My Diabetes? Your doctor will work with you to prescribe the type of insulin that's best for you and your diabetes. Making that choice will depend on many things, including: How you respond to insulin. (How long it takes the body to absorb it and how long it remains active varies from person to person.) Lifestyle choices. The type of food you eat, how much alcohol you drink, or how much exercise you get will all affect how your body uses insulin. Your willingness to give yourself multiple injections per day Your age Your goals for managing your blood sugar Afrezza, a rapid-acting inhaled insulin, is FDA-approved for use before meals for both type 1 and type 2 diabetes. The drug peaks in your blood in about 15-20 minutes and it clears your body in 2-3 hours. It must be used along with long-acting insulin in people with type 1 diabetes. The chart below lists the types of injectable insulin with details about onset (the length of time before insulin reaches the bloodstream and begins to lower blood sugar), peak (the time period when it best lowers blood sugar) and duration (how long insulin continues to work). These three things may vary. The final column offers some insight into the "coverage" provided by the different insulin types in relation to mealtime. Type of Insulin & Brand Names Onset Peak Duration Role in Blood Sugar Management Rapid-Acting Lispro (Humalog) 15-30 min. 30-90 min 3-5 hours Rapid-acting insulin covers insulin needs for meals eaten at the same time as the injection. This type of insulin is often used with Continue reading >>

When Does Humulin Insulin Peak?

When Does Humulin Insulin Peak?

Like all regular insulins, Humulin R helps to prevent your blood sugar level from rising excessively after meals. The activity of Humulin R typically peaks two to four hours after you inject the medication. To synchronize the peak activity of Humulin R with the blood sugar peak associated with eating, you inject this form of insulin approximately 20 to 30 minutes before meals. Humulin N contains insulin in a chemical suspension that slows and prolongs its release. The peak activity of Humulin N typically occurs approximately eight hours after your injection. The duration of activity is approximately 12 to 16 hours. The activity profile of Humulin N makes it useful for maintaining a relatively constant level of insulin in your bloodstream if administered twice daily. This helps keep your blood sugar level steady between meals. Humulin 70/30 is a premixed formulation containing 70 percent Humulin N and 30 percent Humulin R. The premixed drug is convenient if your doctor prescribes both regular and NPH insulin. Two activity peaks occur with this combination medication; one approximately two hours after injection from the regular insulin and a second lower peak approximately 10 hours after injection from the NPH insulin. Variability in Peak Activity The reported peak activity times for various types of Humulin are averages; your experience may be different. After using Humulin for several weeks, you and your doctor may discover from your home glucose monitoring that you are experiencing peak activity earlier or later than the reported average. If this occurs, the timing of your injections may need to be adjusted. Do not change the dose or timing of your insulin injections unless you talk with your doctor. The peak activity of your insulin dose may also change from one day t Continue reading >>

Novolin N (nph) Insulin Peak Time And Onset: What You Should Know

Novolin N (nph) Insulin Peak Time And Onset: What You Should Know

What is Novolin N? Novolin N, also known as Insulin Isophane, is an intermediate acting insulin which is used to treat patients with diabetes. Diabetes is a chronic medical condition where the body cannot produce enough insulin or becomes resistant to it. Insulin is a hormone produced by the pancreas that helps to transport glucose from the bloodstream to body tissue. Diabetic patients cannot naturally produce this hormone. Hence, people with type 1 diabetes require insulin therapy such as Novolin N. Type 2 diabetes can be treated using exercise, diet, and diabetes medications, but this medication can be prescribed to patients with type 2 diabetes as a combination treatment. As well, this insulin drugcan be used to treat diabetes mellitus in both adults and children. When injected under the skin, this medication keeps working in the body for up to 18 hours. Novolin N is usually prescribed together with rapid acting insulin. Insulin Isophane can be used alone or in combination with oral diabetes medications such as Metformin. How to inject Insulin Isophane is injected subcutaneously using an injection pen or syringe. Your health-care provider will show you the best place to inject this medication. Change the injection site every time you take this medication to reduce the chance of getting lipodystrophy. Do not inject insulin isophane into a muscle or vein. You should not change your dosage without your doctor’s recommendation. Make sure you carefully follow your doctor’s instruction on how to take this medication. In case you do not understand anything, ask your doctor for clarification. The dosage of this medication is determined by your medical condition and how you respond to treatment. As you take Novolin N, you should check your blood glucose regularly. You sho Continue reading >>

Cloudy/ milky suspension of human insulin with protamine and zinc. Mixing NPH + Aspart (Novolog ®): Compatible - NovoLog should be drawn into the syringe first. The injection should be made immediately after mixing. NPH + Lispro (Humalog ®): Compatible - Humalog should be drawn into the syringe first. The injection should be made immediately after mixing. NPH +Regular insulin: Always draw the Regular (clear) insulin into the syringe first. Phosphate-buffered insulins ( NPH insulin) should NOT be mixed with lente insulins. Zinc phosphate may precipitate, and the longer-acting insulin will convert to a short-acting insulin to an unpredictable extent. Currently available NPH and short-acting insulin formulations when mixed may be used immediately or stored for future use. NPH HUMAN INSULIN Description Humulin N [Human insulin (rDNA origin) isophane suspension] is a crystalline suspension of human insulin with protamine and zinc providing an intermediate-acting insulin with a slower onset of action and a longer duration of activity (up to 24 hours) than that of Regular human insulin. The time course of action of any insulin may vary considerably in different individuals or at different times in the same individual. As with all insulin preparations, the duration of action of Humulin N is dependent on dose, site of injection, blood supply, temperature, and physical activity. Humulin N is a sterile suspension and is for subcutaneous injection only. It should not be used intravenously or intramuscularly. The concentration of H Continue reading >>

Insulin Actions Times And Peak Times

Insulin Actions Times And Peak Times

A good way to improve your glucose levels is to track the peaks and drops in your glucose , so you can figure out why they happened and how to correct them. Once you identify glucose patterns (they ARE there!), you also want to understand when each of your insulins is active and when they typically stop lowering your glucose. This helps you adjust your doses or food intake to stop unwanted ups and downs in your readings. The table below shows the start, peak, and end times for various insulins with some explanations and typical uses for each. When Does My Insulin Peak and How Long Does It Last? designed to peak, covers meals and lowers high BGs Humalog , Novolog and Apidra insulins currently give the best coverage for meals and help keep the glucose lower afterward. Their glucose lowering activity starts to work about 20 minutes after they are taken, with a gradual rise in activity over the next 1.75 to 2.25 hours. Their activity gradually falls over the next 3 hours with about 5 to 6 hours of activity being common with these insulins.Although insulin action times are often quoted as 3-5 hours, the actual duration of insulin action is typically 5 hours or more. See our article Duration of Insulin Action for more information on this important topic. In general, "rapid" insulins are still too slow for many common meals where the glucose peaks within an hour and digestion is complete within 2-3 hours. The best kept secret on stopping post meal spiking is to eake the injection or bolus earlier before the meal and to eat slower low glycemic carbs. Regular insulin still carries its original name of "fast insulin" but its slower action often works better for people who take Symlin or for those who have gastroparesis (delayed digestion). It is also a great choice for those who Continue reading >>

Insulin Action

Insulin Action

Insulin is a medicine that lowers blood glucose (sugar). There are several types of insulin. Each type of insulin has a certain time period in which it works. In order to understand insulin action, it is helpful to know the onset, peak and duration of the insulin you take. Onset refers to when the insulin starts to work. Peak refers to when the insulin works hardest. Duration refers to how long the insulin works. You are more likely to have a low blood glucose when your insulin is peaking, during periods of increased physical activity or if you are eating less food. If you are having problems with low blood glucose, talk to your healthcare provider about adjusting your insulin. Usual Action Times of Insulin PRODUCT WHEN TO TAKE ONSET PEAK DURATION Rapid-Acting Lispro (Humalog) Aspart (Novolog) Glulisine (Apidra) 0-15 min before meal 10-30 min 30 min - 3 hours 3-5 hours Short-Acting Regular (R) Human 30 min before meal 30-60 min 2-5 hours Up to 12 hours Intermediate-Acting NPH (N) Human Does not need to be given with meal 90 min - 4 hours 4-12 hours Up to 24 hours Long Acting Glargine (Lantus) Detemir (Levemir) Does not need to be given with meal 45 min - 4 hours Minimal Up to 24 hours Continue reading >>

Nph Insulin

Nph Insulin

Neutral Protamine Hagedorn Insulin. Neutral protamine Hagedorn (NPH) insulin is a crystalline suspension of insulin with protamine and zinc, providing an intermediate-acting insulin with onset of action in 1 to 3 hours, duration of action up to 24 hours, and peak action from 6 to 8 hours. NPH insulin usually cannot be administered once daily in the setting of T1DM, at least in combination with rapid-acting monomeric analogue insulin. In the preanalogue era, NPH insulin was used successfully in combination with regular insulin, although this human insulin-based regimen has now been largely supplanted by analogue insulin because of a perceived lower risk of hypoglycemia.310 6.19.6.5.3.3 Intermediate-acting insulins Neutral Protamine Hagedorn ((NPH), lente, and insulin detemir) Neutral Protamine Hagedorn (NPH) and insulin zinc (lente) are different types of intermediate-acting insulins. NPH is a suspension of medium-sized crystals, which include zinc and protamine. Lente is a suspension of large, zinc-containing crystals that have been precipitated in an acetate buffer. These crystals dissolve slowly after subcutaneous injection. NPH and lente have similar pharmacodynamic profiles, with an onset of action approximately 2 h, a peak effect 6–14 h, and duration of action up to 24 h following subcutaneous injection. Intermediate-acting insulins can provide basal and/or prandial insulin, depending on dose and time of administration. Insulin detemir is an acylated insulin analog with threonine removed at position B30, and lysine at position B29 is acylated with a 14-carbon myristoyl fatty acid acylation, resulting in delayed action due to increased binding to albumin. It has a longer duration of action (20 h) than NPH or lente insulins, and less intradose pharmacokinetic varia Continue reading >>

Types Of Insulin

Types Of Insulin

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 >>

Insulin Types: A Review

Insulin Types: A Review

Earlier articles have discussed insulin's role in our bodies, what happens when we don't have it, and why some of us have to take it by injection. But all insulins are not the same. How are they different? WHY are they different? And, how can we use their differences to better self-manage? Insulins are described and subdivided by concentration strength, source, and time of onset/peak. This last category is most critical, but an understanding of all three criteria is needed. Concentration Strength All insulins sold in the United States today are of U-100 strength, 100 units of insulin per cc of fluid. But there are other dilutions in other countries, and if you were to encounter one of these (all perfectly usable), and inject your usual volume of insulin, you'd get a different amount of insulin. You'd get the wrong dosage. Source At one time, all insulin was produced by laboratory animals, most often cows and pigs. In the last decade, however, American insulin manufacturers have almost completely shifted to use of "recombinant DNA" technology, enabling laboratory production of a close analog to real human insulin. This "human" insulin is said to more closely match our endogenous (pancreatic) insulin. Although labelled much like "animal source" insulins, recombinant DNA insulins are not quite the same, either in time-of-onset or in amount of insulin required. Experience shows that any switch between the one and the other must be done with care, and under your doctor's supervision--the types might be different enough to cause you trouble otherwise. Time of Onset/Peak The different insulin types: Humalog, Regular, NPH, Lente, Ultralente, and the pre-mixes: 70/30 and 50/50, divided and distinguished by their time of onset and duration. As shown in the chart below, critical q Continue reading >>

Long-acting Insulin: How It Works

Long-acting Insulin: How It Works

When you eat, your pancreas releases a hormone called insulin. Insulin moves sugar (glucose) from your blood to your cells for energy or storage. If you take insulin, you may need some at mealtime to help lower your blood sugar after you eat. But even between meals, you need insulin in small amounts to help keep blood sugar stable. This is where long-acting insulin comes in. If you have diabetes, either your pancreas can’t produce enough (or any) insulin, or your cells can’t use it efficiently. To control your blood sugar, you need to replace or supplement the normal function of your pancreas with regular insulin injections. Insulin comes in many types. Each type differs in three ways: onset: how quickly it starts working to lower your blood sugar peak: when its effects on your blood sugar are strongest duration: how long it lowers your blood sugar According to the U.S. Food and Drug Administration (FDA), the five types of insulin are: Rapid-acting insulin: This type starts to work just 15 minutes after you take it. It peaks within 30 to 90 minutes, and its effects last for three to five hours. Short-acting insulin: This type takes about 30 to 60 minutes to become active in your bloodstream. It peaks in two to four hours, and its effects can last for five to eight hours. It is sometimes called regular-acting insulin. Intermediate-acting insulin: The intermediate type takes one to three hours to start working. It peaks in eight hours and works for 12 to 16 hours. Long-acting insulin: This type takes the longest amount of time to start working. The insulin can take up to 4 hours to get into your bloodstream. Pre-mixed: This is a combination of two different types of insulin: one that controls blood sugar at meals and another that controls blood sugar between meals. Lo Continue reading >>

Time-action Characteristics Of Regular And Nph Insulin In Insulin-treated Diabetics.

Time-action Characteristics Of Regular And Nph Insulin In Insulin-treated Diabetics.

Abstract The time course of action of regular and NPH insulins injected sc was studied in 15 insulin-treated diabetics over a 24-h period during which they received a constant infusion of glucose. The blood glucose began to decline in 1.2 +/- 0.1 h (range, 0.5--2) and reached its nadir in 5.7 +/- 0.3 h (range, 4--8) after the sc injection of regular insulin. The peak effect of regular insulin usually persisted for several hours, and the total duration of action was 16.2 +/- 1.1 h (range, 9--24). Both the time of peak effect and the total duration of action were considerably prolonged compared to data provided in standard textbooks. Free insulin increased to a peak in 2.7 +/- 0.3 h (range, 1--4) after regular insulin injection and then returned to baseline by 8.8 +/- 0.96 h. Subcutaneous injection of NPH insulin decreased the blood glucose by 2.4 +/- 0.5 h (range, 1--7), with a maximal effect at 11.0 +/- 1.4 h (range, 5--19). The total duration of effect on blood glucose was 25.1 +/- 0.7 h (range, 20--29). These values are similar to those in standard textbooks. Although the total insulin levels increased after the injection of NPH insulin, there was very little if any elevation in free insulin. Recognition of the prolonged effect of regular insulin is important in establishing an insulin treatment regime for diabetic patients. Continue reading >>
