An intermediate-acting, mixed insulin[2] of 40% R/neutral insulin and 60% NPH/isophane insulin[3] made by Novo Nordisk. Mixtard 40[4] contains 60% isophane insulin crystals, as does Penmix 40, Humulina 40/60, and Huminsulin Profil IV.
Mixtard 40 was discontinued December 31, 2007.[5][6]
Lilly's Humulin 40/60 for the North American market was similar, and is also discontinued.
Mixed insulins cover a wide range as they can be animal origin, r-DNA/GE/GM origin or analog insulins. They can also vary in the fraction (amount or percent) of the two types (R/neutral and NPH/isophane) of insulin used to make a non-analog mix, and in the percentage of fast/rapid-acting analog insulin and slower-acting protamine suspended analog insulin.
For some reason, those in the US choose to list the slower, NPH/isophane based insulin fraction first, such as Humulin or Novolin 70/30. The rest of the world gives the faster insulin top billing and the result is 30/70[7]. Regardless of how this is written, it means that the insulin is made up of 70% NPH/isophane insulin and 30% R/neutral insulin.
The most common mixes are 70/30 (30/70) (non analog) or 75/25 (25/75) (analog). There are no currently-marketed mixes which combine insulins of different origins. Eli Lilly's form of beef/pork Iletin and Novo Nordisk's Lentard were discontinued some time ago. Here are the most common ones that could cause confusion:
