Animals were housed with 12-h day–night cycles with lights on at am, in a holding room with target temperatures of 21±2 °C and target relative humidity from 30–70%.Pigs were single housed in enriched pens with the possibility of social interaction.Pigs were allowed daily exercise in corridors and received apples as treats.Formulations of insulin aspart with niacinamide were administered subcutaneously to female pigs (55–85 kg) in a full cross-over dose-response study.The rate of absorption for each formulation was expressed as the area under the curve (AUC)Pigs (70–90 kg) were anesthetized using Zoletil mixture (1 mg/10 kg; Virbac, Denmark) with intravenous supplement of propolipid (Fresenius Kabi, Sweden).
Domestic pigs (Landrace-Yorkshire-Duroc [LYD]) were accommodated and cared for by competent personnel and supervised by laboratory animal veterinarians.
Niacinamide mediates the acceleration of initial insulin aspart absorption, and the mechanism of action appears to be multifaceted.
Niacinamide increases the initial abundance of insulin aspart monomers and transport of insulin aspart after subcutaneous administration, and also mediates a transient, local vasodilatory effect.
By reducing the tendency to remain self-associated as hexamers after subcutaneous administration, the speed of absorption into the circulation is increased, and insulin aspart reaches peak plasma concentrations more rapidly compared with RHI, to better mimic the normal mealtime insulin response ().
Nevertheless, despite such advances in insulin development, many patients with type 1 diabetes (T1D) or insulin-dependent type 2 diabetes (T2D) remain unable to control postprandial hyperglycemia and hence meet or maintain Hb A).
At high concentrations, a hydrotrope such as niacinamide is considered likely to shift the balance of oligomerization of insulin from hexamers towards dimers and monomers, making the readily absorbed monomer more abundant.
