Leo Retard was a porcine NPH/Isophane insulin [4] [5] made by Nordisk. [1]
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 Pork Actrapid 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.
