Novolin R--Regular/Neutral GE insulin.


Novo Nordisk's brand of "R"-action insuln is known by three names: Actrapid [2][3][4] in Europe: ReliOn/Novolin R and Novolin R in North America.

As of January 1, 2010, Novo discontinued offering Novolin R in cartridges for refillable insulin pens. [5][6]

Other companies make similar products--they are: Huminsulin Normal, Humulin R [7][8] and Humulin S [9][10][11] by Eli Lilly and Insuman Rapid [12][13] and Winthrop Rapid both by Aventis.

A short-acting, soluble, non-suspended insulin produced from r-DNA/GE/GM, bovine, or porcine sources. From 1921 to the 1930's when PZI was developed, R was the only kind of insulin available.

While both R/neutral and semilente insulins are considered fast-acting, they differ in a few ways. As above, there's no suspension or buffer [14] in R/neutral; it's totally dissolved and soluble, meaning it can safely be used intravenously. [15]

The very small insulin particles in semilente insulin are suspended by zinc. [16] Semilente is cloudy, has an acetate buffer and cannot be used intravenously.

R/Neutral insulin cannot be reliably mixed with Lente or Ultralente insulins. [17][18]. Semilente can; the ratio of 3 parts semilente insulin to 7 parts ultralente insulin produces Lente insulin [19]
