insulin lispro + regular insulin

This refers to a hypothesized combination of insulin lispro, a rapid-acting insulin analog, and regular human insulin, a short-acting insulin. Based on the search results, this specific combination is not a standard commercially available product and is generally not recommended for clinical use. Insulin lispro should typically not be mixed with other insulin preparations except for NPH insulin. While insulin lispro is available in premixed formulations, these combine insulin lispro with insulin lispro protamine (an intermediate-acting insulin), such as Humalog Mix 75/25 and Humalog Mix 50/50, not with regular human insulin.
