Insulin lispro

12.1 Mechanism of Action Regulation of glucose metabolism is the primary activity of insulins and insulin analogs, including insulin lispro products. Insulins lower blood glucose by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulins inhibit lipolysis and proteolysis and enhance protein synthesis.

1 INDICATIONS AND USAGE ADMELOG is indicated to improve glycemic control in adult and pediatric patients with diabetes mellitus. ADMELOG is a rapid-acting human insulin analog indicated to improve glycemic control in adult and pediatric patients with diabetes mellitus. ( 1 )

2 DOSAGE AND ADMINISTRATION See Full Prescribing Information for important preparation and administration instructions. ( 2.1 , 2.2 , 2.3 , 2.4 ) Rotate injection sites to reduce risk of lipodystrophy and localized cutaneous amyloidosis. ( 2.2 ) Subcutaneous injection ( 2.2 ): Administer ADMELOG by subcutaneous injection into the abdominal wall, thigh, upper arm, or buttocks within 15 minutes before a meal or immediately after a meal. Rotate injection sites to reduce risk of lipodystrophy and localized cutaneous amyloidosis. Continuous subcutaneous infusion (Insulin Pump) ( 2.2 ): Refer to the insulin infusion pump user manual to see if ADMELOG can be used. Use in accordance with the insulin pump instructions for use. Administer ADMELOG by continuous subcutaneous infusion using an insulin pump in a region recommended in the instructions from the pump manufacturer. Rotate infusion sites to reduce risk of lipodystrophy and localized cutaneous amyloidosis. Do not mix with other insulins or diluents in the pump. Intravenous Infusion: Administer ADMELOG by intravenous infusion ONLY after dilution and under medical supervision. ( 2.2 ) The dosage of ADMELOG must be individualized based on the route of administration and the patient's metabolic needs, blood glucose monitoring results and glycemic control goal. ( 2.3 ) 2.1 Important Preparation and Administration Instructions Always check insulin labels before administration [see Warnings and Precautions (5.4) ] . Inspect ADMELOG visually before use. It should appear clear and colorless. Do not use ADMELOG if particulate matter or coloration is seen. Use ADMELOG SoloStar prefilled pen with caution in patients with visual impairment who may rely on audible clicks to dial their dose. Do NOT mix ADMELOG with other insulins when administering using a continuous subcutaneous infusion pump. 2.2 Preparation and Administration Instructions for the Approved Routes of Administration Subcutaneous Injection Administer the dose of ADMELOG subcutaneously within fifteen minutes before a meal or immediately after a meal into the abdominal wall, thigh, upper arm, or buttocks. Rotate injection site within the same region from one injection to the next to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis [see Warnings and Precautions (5.2) , Adverse Reactions (6) ] . During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions (5.2) ] . ADMELOG administered by subcutaneous injection should generally be used in regimens with intermediate or long-acting insulin. The ADMELOG SoloStar prefilled pen dials in 1-unit increments. Prior to subcutaneous use, ADMELOG may be diluted with sterile 0.9% Sodium Chloride Injection. Dilute one-part ADMELOG to one-part 0.9% Sodium Chloride Injection to yield a concentration one-half that of ADMELOG (equivalent to U-50). If diluted ADMELOG is not used immediately, refrigerate at 2°C to 8°C (36°F to 46°F) for no more than 24 hours or store at room temperature up to 30°C (86°F) for 4 hours. Discard the unused diluted ADEMLOG after 24 hours if refrigerated or after 4 hours if stored at room temperature. Continuous Subcutaneous Infusion (Insulin Pump) Refer to the continuous subcutaneous insulin infusion pump user manual to see if ADMELOG can be used with the insulin pump. Use ADMELOG in accordance with the insulin pump system's instructions for use. Administer ADMELOG by continuous subcutaneous infusion in a region recommended in the instructions from the pump manufacturer. Rotate infusion sites within the same region to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis [see Warnings and Precautions (5.2) , Adverse Reactions (6) ] . Train patients using continuous subcutaneous insulin infusion therapy to administer insulin by injection and have alternate insulin therapy available in case of insulin pump failure [see Warnings and Precautions (5.8) ]. During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions (5.2) ] . Change ADMELOG in the pump reservoir at least every 7 days or according to the pump user manual, whichever is shorter. Change the infusion sets and the infusion set insertion site according to the manufacturer's user manual. Do NOT dilute or mix ADMELOG when administering by continuous subcutaneous infusion. Do NOT expose ADMELOG in the pump reservoir to temperatures greater than 98.6°F (37°C). Intravenous Administration Administer ADMELOG intravenously ONLY under medical supervision [see Warnings and Precautions (5.3 , 5.6) ] . Dilute ADMELOG to concentrations from 0.1 unit/mL to 1 unit/mL using 0.9% Sodium Chloride Injection, USP [see How Supplied/Storage and Handling (16.2) ] . Closely monitor of blood glucose and po

6 ADVERSE REACTIONS The following adverse reactions are discussed elsewhere: Hypoglycemia [see Warnings and Precautions (5.3) ] Hypoglycemia Due to Medication Errors [see Warnings and Precautions (5.4) ] Hypersensitivity Reactions [see Warnings and Precautions (5.5) ] Hypokalemia [see Warnings and Precautions (5.6) ] Adverse reactions associated with ADMELOG include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, pruritus, and rash.

Adverse Reactions with Subcutaneous Injections of ADMELOG Two clinical trials with ADMELOG were conducted: one in patients with type 1 diabetes and one in patients with type 2 diabetes [see Clinical Studies (14) ] . The data in Table 1 reflect the exposure of 252 patients with type 1 diabetes to ADMELOG with mean exposure duration of 49 weeks. The type 1 diabetes population had the following characteristics: Mean age was 43 years and mean duration of diabetes was 20 years. Fifty-nine percent were male, 80% were White, 6% were Black or African American and 7% were Hispanic. At baseline, the mean eGFR was 90 mL/min/1.73 m 2 and 49% of patients had eGFR ≥90 mL/min/1.73 m 2 . The mean BMI was 26 kg/m 2 . The mean HbA1c at baseline was 8.07%. Two hundred fifty-three patients with type 2 diabetes were exposed to ADMELOG with mean exposure duration of 25 weeks. The type 2 diabetes population had the following characteristics: Mean age was 62 years and mean duration of diabetes was 17 years. Fifty-four percent were male, 90% were White, 6% were Black or African American and 17% were Hispanic. At baseline, the mean eGFR was 77 mL/min/1.73 m 2 and 27% of patients had eGFR ≥90 mL/min/1.73 m 2 . The mean BMI was 32 kg/m 2 . The mean HbA1c at baseline was 7.99%. Common adverse reactions were defined as reactions that occurred in ≥5% of the population studied. Common adverse reactions (other than hypoglycemia) during a clinical trial in patients with type 1 diabetes mellitus are listed in Table 1. In a 26-week clinical trial in patients with type 2 diabetes mellitus, no adverse reactions (other than hypoglycemia) occurred in ≥5% of ADMELOG-treated patients (n=253) were observed. Table 1: Adverse Reactions that Occurred in ≥5% of ADMELOG-Treated Patients with Type 1 Diabetes in a 52-Week Trial ADMELOG + Insulin Glargine (100 units/mL), % (n=252) Nasopharyngitis 13% Upper respiratory tract infection 6% Severe Hypoglycemia Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including ADMELOG [see Warnings and Precautions (5.3) ] . The rates of reported hypoglycemia depend on the definition of hypoglycemia used, diabetes type, insulin dose, intensity of glucose control, background therapies, and other intrinsic and extrinsic patient factors. For these reasons, comparing rates of hypoglycemia in clinical trials for ADMELOG with the incidence of hypoglycemia for other products may be misleading and also, may not be representative of hypoglycemia rates that will occur in clinical practice. In the ADMELOG trials, severe hypoglycemia was defined as an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. The incidence of severe hypoglycemia in patients receiving ADMELOG with type 1 diabetes mellitus and type 2 diabetes mellitus was 13.5% at 52 weeks and 2.4% at 26 weeks, respectively [see Clinical Studies (14) ] . Adverse Reactions Associated with Insulin Initiation and Intensification of Glucose Control Intensification or rapid improvement in glucose control has been associated with a transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy. However, long-term glycemic control decreases the risk of diabetic retinopathy and neuropathy. Lipodystrophy Long-term use of insulin, including ADMELOG, can cause lipodystrophy at the site of repeated insulin injections or infusion. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue) and may affect insulin absorption [see Dosage and Administration (2.2) ] . Weight Gain Weight gain can occur with insulins, including ADMELOG, and has been attributed to the anabolic effects of insulin and the decrease in glucosuria. Peripheral Edema Insulins, including ADMELOG, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
