Pork Insulatard

Pork Insulatard insulin.


Note that some countries have the brand name in U40 strength.

Pork Insulatard was a porcine NPH/Isophane insulin [4][5] made by Novo Nordisk.

It is similar to CP Pharma's Hypurin Porcine Isophane, [6][7] to Beta's Betasint Porcine NPH and to the now-defunct Eli Lilly product Iletin II NPH[8][9][10]

Like all other isophane/protamine suspended insulins, [11] it is a crystalline suspension with protamine and zinc.

After December, 2007, Novo Nordisk no longer offered this insulin in the UK; [12][13][14][15][16] according to the Novo Nordisk Australasia Home Page, [17] it was discontinued there by December, 2006. Those using it now order Hypurin Porcine Isophane from CP Pharma [18] or Betasint Porcine NPH from Beta Laboratorios.
