Detail-Document #251005 −This Detail-Document accompanies the related article published in− PHARMACIST’S LETTER / PRESCRIBER’S LETTER October 2009 ~ Volume 25 ~ Number 251005 How to Switch Between Insulin Products Switching insulins should always be done with prescriber approval and close monitoring. Advise patients to closely monitor blood glucose levels after switching insulins. If switching between human insulin brands (e.g., Humulin R to Novolin R, Humulin N to Novolin N, or Humulin R/N or Novolin R/N to “store brand” R/N), keep the number of units each day the same. However, because these brands are not AB rated you may need to contact the prescriber for approval to switch between brands. See our Comparison of Insulins chart for meal timing, onset, peak, duration of action, and other information. Also see our algorithm Initiation and Adjustment of Insulin Regimens for Type 2 Diabetes. Clinical Scenario NPH to Long-acting NPH to insulin detemir (Levemir) Recommendation/Comments • • • • NPH to insulin glargine (Lantus) • • • Long-acting to NPH Insulin detemir (Levemir) to NPH Insulin glargine (Lantus) to NPH Convert unit-per-unit.1 Some patients on basal-bolus insulin may require more Levemir than NPH.1 Give Levemir once daily, or divided twice daily if necessary for control.1 Do not mix Levemir with other insulins.1 NPH once daily: convert unit-per-unit and give once daily.2 NPH twice daily: reduce daily dose by 20% and give once daily.2 Do not mix Lantus with other insulins.2 • • Convert unit-per-unit.3 Give NPH at bedtime or split twice daily (e.g., 50:50 or 2/3 in AM and 1/3 before dinner or at bedtime).3,4,5 • • Convert unit-per-unit.3 Give NPH at bedtime or split twice daily (e.g., 50:50 or 2/3 in AM and 1/3 before dinner or at bedtime).3,4,5 More. . .

A second table also provides information about insulin pens and other administration devices. Availability. The new insulin analogs and U-500 insulin are available by prescription only. Other insulins are available OTC, but a prescription may be required for insurance company reimbursement. Type. Species of insulin available in the U.S. will soon be limited to human insulins and human insulin analogs. Years ago, beef insulins were removed from the U.S. market because of a theoretical concern for transmission of bovine spongiform encephalopathy (mad cow disease). For information on obtaining beef insulin from other countries, go to http://www.fda.gov/cder/drug/beefandporkinsulin/ default.htm. In July 2005, Lilly announced the discontinuation of it’s pork insulins (Iletin II regular and NPH), with the expectation that stock will be depleted by the end of the year.29 Demand for these products has declined in recent years and recombinant human insulin products are easier to manufacture. The dose is usually similar when converting from animal to human insulin. Consider reducing the initial human insulin dose by 10% to 20% in patients receiving more than 100 units per day of animal insulin.33 Lilly will also discontinue two long-acting human insulins, Humulin L (lente) and Humulin U (ultralente), with stock depletion also expected by the end of 2005.29 A recent statement from the International Diabetes Federation concludes that, in the absence of strong evidence favoring one species of insulin over another, patients should not be converted to a different species unless it has a clear advantage for the patient.31 Since all insulins have slightly different properties, a particular patient may better tolerate one species of insulin better than another. In the past, anecdotal reports raised concern that human insulins might have a higher risk of hypoglycemia, but this concern has not been supported by further clinical research.31 Onset, peak, duration. The tables above compare the onset, peak, and duration of action of insulin formulations after subcutaneous injection. These values are approximate since many factors can affect the pharmacokinetics of insulin.1 Rapid-acting insulin analogs (insulins lispro, aspart, and glulisine) have small modifications to the insulin amino acid sequence that makes them dissociate into monomers more quickly after subcutaneous injection. This allows more rapid absorption into the systemic circulation. There is also less variability in absorption with rapid-acting insulin analogs than regular insulin.3 Rapidacting analogs may provide better postprandial glucose control and less nocturnal hypoglycemia than regular insulin, but it is unclear that these benefits translate into long-term improvements in outcome.31, 32 After SC injection, intermediate- and long-acting insulin molecules aggregate into hexamers (groups of six molecules) at the injection site. They slowly dissociate into dimers and monomers which are absorbed into the systemic circulation. Insulin detemir is acylated (linked to a fatty acid chain). This promotes hexamer formation and reversible binding to albumin after it reaches the bloodstream.2 This helps prolong it’s duration of action. The time-action profile of insulin detemir is less variable than NPH.2 This may reduce the risk of hypoglycemia and weight gain.3 Interindividual variability is less with insulin glargine than with NPH and ultralente.4 Insulin lispro protamine and NPH insulin have similar pharmacokinetic profiles.5 Newer basal insulins, like insulin glargine, reduce nocturnal hypoglycemia. However, it is unclear whether this benefit improves long-term glycemic control.31 More. . . Copyright © 2006 by Therapeutic Research Center Pharmacist’s Letter / Prescriber’s Letter ~ P.O.

Insulin suspensions should be gently shaken before each injection. Pens and cartridges of insulin suspensions should be rolled and tipped back and forth ten to 20 times to re-suspend the insulin and then primed before each injection.6, 7 Insulin mixtures or dilutions should not be used in external pumps. Meal timing. The American Diabetes Association (ADA) recommends that rapid-acting insulin analogs (alone or with intermediate- or long-acting insulin) be injected within 15 minutes before or immediately after a meal.1 It may be helpful to give the dose after a meal in young children who are unreliable eaters.8 Regular insulin is usually given 30 minutes before meals. Meal-timing for premixed formulations is based on whether the mixture contains rapid-acting or regular insulin. In one algorithm, the interval between injecting insulin and starting a meal depends on blood glucose monitoring. For regular insulin, the interval is 20 to 30 minutes for a blood glucose of 65 to 150 mg/dL, 30 to 45 minutes for >150 to 250 mg/dL, and 50 to 60 minutes for >250 mg/dL. Insulin lispro can be injected immediately before meals when blood glucose is 65 to 150 mg/dL. The interval between injecting and eating is 10 to 20 minutes for >150 to 250 mg/dL, and 20 to 30 minutes for >250 mg/dL.8 A more detailed algorithm is outlined in the ADA’s book, Intensive Diabetes Management.9 Formulations and delivery devices. All insulins are available in 10 mL vials (U-100; 100 units/mL). The only exception is U-500 (500 units/mL) regular human insulin (20 mL vial), which is available from Lilly by prescription only for patients who require more than 200 units/day.5 Some formulations are available in prefilled disposable pens or reusable pens with disposable insulin cartridges. These products, reviewed in a table above, are for SC injection. Although they may be more expensive than vials, they can make insulin administration simpler, more convenient, and less error-prone than withdrawing insulin from a vial and injecting with a syringe. Injections with an insulin pen may also be less painful; the needles are small and are not dulled by the withdrawal of insulin from a vial to syringe. Jet injectors (such as AdvantaJet, Medi-Jector, and Vitajet) avoid the use of needles, cost approximately $250-$500, weigh about 8 oz, and require frequent cleaning.10, 11 Exubera, approved January 2006, was the first insulin formulation to be administered by oral inhalation. In October 2007, due to poor acceptance by patients and prescribers, Pfizer announced it would be discontinuing sales of Exubera. Appearance. Patients and clinicians should check the appearance of an insulin before using it. Rapid- and short-acting insulins and insulin glargine should be clear; the others should be cloudy.1, patients that insulin glargine can be mistaken for a shorter-acting insulin because it looks clear. 5 Warn Compatibility. Human and pork insulins can probably be mixed, but there is no reason to do so.6 There is no information on the compatibility between Novolin and Humulin insulins; incompatibility could result from differences in buffering agents between the two product lines. When mixed with another insulin, a rapid- or short-acting insulin should be drawn up in the syringe first in order to maintain clarity in the vial. The manufacturer recommends against mixing insulin glargine with other insulins. In an animal study, mixing it with regular insulin delayed the onset and peak of regular insulin.12 A preliminary study in 14 diabetics found no effect on glycemic control when insulin glargine was mixed with lispro or aspart. The mixture did turn cloudy.13 Pramlintide (Symlin), a synthetic amylin analog, is administered by SC injection. The manufacturer recommends against mixing pramlintide with insulin.14 However, a recent study found that mixing it with short- or long-acting insulin in the same syringe before SC injection did not affect the pharmacokinetics of either agent or change glucose pharmacodynamics.15 Although some insulin mixtures are chemically stable under refrigeration for up to three months, the possibility of microbial contamination must be considered.16 A diluent is not available for Novo Nordisk insulins.17 In the past, there were three Lilly diluents. Now, a single diluent is available (call 317-276-1610) for use with Humalog and Humalog 75/25 or 70/30; Humulin R, N, 70/30 and 50/50; Iletin II pork NPH and U-500.18 It cannot be used for Humulin L or R, or More. . .

Opened vials of diluent and most diluted insulins are stable for one month at room temperature.6 Diluted Humalog is stable at room temperature for 14 days.19 Stability. Unopened insulin products should be stored in the refrigerator (36 to 46˚ F; 2 to 8˚ C) with the exception of packaged Exubera unit dose blisters (stored at room temperature, 25ºC [77ºF]). Once the stopper or seal has been punctured by a needle, the product is considered to be “open” or “in-use.” In-use insulin vials are usually kept at room temperature (59 to 86˚ F; 15 to 30˚ C) to make injections less painful. At room temperature, opened vials are stable for about 28 days (Levemir is the exception at 42 days). The duration of stability at room temperature varies for other insulin products. In-use insulin pens and cartridges should be stored at room temperature. For Exubera, once the foil overwrap is opened (inuse), the unit dose blisters should be stored at room temperature and used within three months. [Note: Exubera has been discontinued.] Users of this document are cautioned to use their own professional judgment and consult any other necessary or appropriate sources prior to making clinical judgments based on the content of this document.
