Huminsulin Basal is an Eli Lilly brand name for their NPH-based insulin product. [4]

It is an intermediate-acting insulin.

Like all other isophane/protamine suspended insulins, [5] it is a crystalline suspension with protamine.

NPH (Isophane) insulin was originally developed by Novo Nordisk labs in 1946, as an insulin with intermediate action.

This type of insulin tends to have an onset of 2-4 hours, a peak action of 4-10 hours, and a total duration of 10-20 hours, in humans.

Humulin N or generic NPH, and their Novo Nordisk competitor Novolin N [6] aka Insulatard, [7][8][9]and aka Protaphane [10] are available in the USA with no prescription.

In the UK, Humulin N is known as Humulin I ("I" standing for its isophane suspension.); [11][12][13] in the US, it's called Humulin N. Elsewhere it's called Umuline NPH, Humulina NPH and Humuline NPH. Aventis also makes two similar NPH insulins called Insuman Basal [14][15] and Winthrop Basal.

Specifications of NPH/isophane insulin[]
