Actions of Insuline Lantus Opticlik in details
Pharmacology: Pharmacodynamics: The primary activity of insulin, including Insuline Lantus Opticlik, is regulation of glucose metabolism. Insulin and its analogues lower blood glucose levels bu stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in the adipocyte, inhibits proteolysis and enhances protein synthesis.
Insuline Lantus Opticlik differs from other insulins because its unique structure provides a smooth and peakless profile with a prolonged duration of action of 24 hrs (end of observation period) compared to 14.5 hrs for neutral protamine hagedorn (NPH) human insulin.
In clinical studies, IV Insuline Lantus Opticlik and human insulin have been shown to be equipotent when given at the same doses. The onset of action of Insuline Lantus Opticlik is slower than NPH human insulin. The effect profile of Insuline Lantus Opticlik is smooth and peakless, and the duration of its effect is prolonged compared to NPH human insulin.
Pharmacokinetics: After SC injection of Insuline Lantus Opticlik, the insulin serum concentrations indicate a slower, more prolonged absorption and a lack of a peak in comparison to NPH human insulin. Concentrations are, thus, consistent with the time profile of the pharmacodynamic activity of Insuline Lantus Opticlik.
Insuline Lantus Opticlik is a human insulin analogue that has been designed to have low solubility at neutral pH. At pH 4, the pH of the Insuline Lantus Opticlik injection solution, it is completely soluble. After injection into the SC tissue, the acidic solution is neutralized, leading to formation of microprecipitates from which small amounts of Insuline Lantus Opticlik are continuously released, providing a smooth, peakless, predictable time/concentration profile and a prolonged duration of action. This allows once daily dosing to meet a patient's basal insulin needs.
Insuline Lantus Opticlik is partly degraded in the SC depot at the carboxyl terminus of the B-chain to form the active metabolites, with similar in vitro activity to insulin.
How should I take Insuline Lantus Opticlik?
A nurse or other trained health professional may give you Insuline Lantus Opticlik, recombinant. You may also be taught how to give your medicine at home. Insuline Lantus Opticlik, recombinant is given as a shot under your skin.

Insuline Lantus Opticlik administration
SubQ: Do not use if solution is viscous or cloudy; use only if clear and colorless with no visible particles. Insuline Lantus Opticlik should be administered consistently at the same time each day. Cold injections should be avoided. SubQ administration is usually made into the thighs, arms, buttocks, or abdomen; absorption rates vary amongst injection sites; be consistent with area used while rotating injection sites within the same region to avoid lipodystrophy or localized cutaneous amyloidosis. Rotating from an injection site where lipodystrophy/cutaneous amyloidosis is present to an unaffected site may increase risk of hypoglycemia. Do not dilute or mix Insuline Lantus Opticlik with any other insulin formulation or solution. Insuline Lantus Opticlik prefilled pens are available in concentrations of 100 units/mL and 300 units/mL. Prefilled pens are calibrated to display the actual insulin units administered (no dosage conversion needed) and will administer up to 80 units per injection, in 1 unit increments (Lantus SoloStar, Basaglar KwikPen, Basaglar Tempo Pen, Insuline Lantus Opticlik SoloStar) or up to 160 units per injection, in 2 unit increments (Insuline Lantus Opticlik Max SoloStar, Insuline Lantus Opticlik DoubleStar [Canadian product]). Insuline Lantus Opticlik Max SoloStar and Insuline Lantus Opticlik DoubleStar (Canadian product) prefilled pens are only recommended for use in patients requiring at least 20 units of Insuline Lantus Opticlik per day. Do not use a syringe to withdraw concentrated Insuline Lantus Opticlik (300 units/mL) from a prefilled pen for administration. Cartridges (Canadian product) are to be used only with reusable pens recommended by the manufacturer (refer to product labeling).
Insuline Lantus Opticlik pharmacology
Mechanism of Action
The primary activity of insulin, including Insuline Lantus Opticlik, is regulation of glucose metabolism. Insulin and its analogs lower blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis and proteolysis, and enhances protein synthesis.
Pharmacodynamics
Onset of Action
The pharmacodynamic profiles for Insuline Lantus Opticlik given subcutaneously as a single dose of 0.4, 0.6, or 0.9 U/kg in a euglycemic clamp study in patients with type 1 diabetes showed that on average, the onset of action develops over 6 hours post-dose for all three single doses of Insuline Lantus Opticlik.
Single Dose Pharmacodynamics
The pharmacodynamics for single 0.4, 0.6, and 0.9 U/kg doses of Insuline Lantus Opticlik in 24 patients with type 1 diabetes mellitus was evaluated in a euglycemic clamp study. On a unit-to-unit basis, Insuline Lantus Opticlik had a lower maximum (GIRmax) and 24 hour glucose lowering effect (GIR-AUC0–24) compared to LANTUS. The overall glucose lowering effect of Insuline Lantus Opticlik 0.4 U/kg was 12% of the glucose lowering effect of an equivalent dose of LANTUS. Glucose lowering at least 30% of the effect of a single 0.4 U/kg dose of LANTUS was not observed until the single dose of Insuline Lantus Opticlik exceeded 0.6 U/kg.
Multiple Once Daily Dose Pharmacodynamics
The pharmacodynamics of Insuline Lantus Opticlik after 8 days of daily injection was evaluated in 30 patients with type 1 diabetes. At steady state, the 24 hour glucose lowering effect (GIR-AUC0–24) of Insuline Lantus Opticlik 0.4 U/kg was approximately 27% lower with a different distribution profile than that of an equivalent dose of LANTUS. The glucose lowering effect of a Insuline Lantus Opticlik dose increased with each daily administration.
The pharmacodynamic profile for Insuline Lantus Opticlik given subcutaneously as multiple once-daily subcutaneous injections of 0.4 U/kg in a euglycemic clamp study in patients with type 1 diabetes, is shown in Figure 1.

Pharmacokinetics
Absorption and Bioavailability
The pharmacokinetic profiles for single 0.4, 0.6, and 0.9 U/kg doses of Insuline Lantus Opticlik in 24 patients with type 1 diabetes mellitus was evaluated in a euglycemic clamp study. The median time to maximum serum insulin concentration was 12 (8–14), 12 (12–18), and 16 (12–20) hours, respectively. Mean serum insulin concentrations declined to the lower limit of quantitation of 5.02 µU/mL by 16, 28, and beyond 36 hours, respectively.
Steady state insulin concentrations are reached by at least 5 days of once daily subcutaneous administration of 0.4 U/kg to 0.6 U/kg doses of Insuline Lantus Opticlik over 8 days in patients with type 1 diabetes mellitus.
After subcutaneous injection of Insuline Lantus Opticlik, the intra-subject variability, defined as the coefficient of variation for the insulin exposure during 24 hours was 21.0% at steady state.
Elimination
After subcutaneous injection of Insuline Lantus Opticlik in diabetic patients, Insuline Lantus Opticlik is metabolized at the carboxyl terminus of the B-chain with formation of two active metabolites M1 (21A-Gly-insulin) and M2 (21A-Gly-des-30B-Thr-insulin). The in vitro activity of M1 and M2 were similar to that of human insulin.
