NPH insulin time activity profile.


Humulin ReliOn N is Eli Lilly's brand name for their NPH-based insulin product. [4] This insulin is also known as Umuline NPH, Humuline NPH, Huminsulin Basal and Humulina NPH. Novo-Nordisk had been producing the ReliOn brand insulins since their inception in 2000, but in October 2010, WalMart signed with Eli Lilly for their production.[5][6] The ReliOn insulins are still offered in the same types, R, NPH, and 70/30 mix, but they are produced by Eli Lilly and branded as Humulin/ReliOn insulins. [7][8][9] Novolin insulins have NOT been discontinued; these insulins are available as Novolin N, Novolin R, and Novolin 70/30. Only the ReliOn/Novolin branded insulins have been phased out.

It is an intermediate-acting insulin.

Like all other isophane/protamine suspended insulins [10], 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 [11] aka Insulatard [12][13][14] and aka Protaphane, [15] are available in the USA with no prescription.

In the UK, Humulin N is known as Humulin I ("I" standing for its isophane suspension.); [16][17][18] elsewhere it's called Huminsulin Basal. Aventis also makes two similar NPH insulins called Insuman Basal [19][20] and Winthrop Basal.

Specifications of NPH/isophane insulinEdit

British National Formulary [21] defines this type as: A sterile suspension bovine or porcine or of human insulin in the form of a complex obtained by the addition of protamine sulphate or another suitable protamine.

British Pharmacoepia and United States Pharmacopia definitions: [21]

Sterile buffered suspension of insulin in the form of a complex obtained by addition of suitable protamine. Prepared from crystalline insulin. pH 6.9 - 7.5 iso-osmotic with blood. Contains for each 100 units of insulin, 300 - 600 g protamine sulphate and not more than 40 g zinc, a suitable bactericide and sodium phosphate as buffering agent.
