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

Humulin R is one of several brands of "Regular" (short-acting) insulin, used for a quick consumption of blood sugar with little delay.

It consists of zinc insulin crystals dissolved in clear fluid with no additives to alter its action or speed. [2]

Other brands with the same action profile include:

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.

Human activity profile for r-DNA/GE/GM R (Regular)/Neutral insulin. See links for dog activity.

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 [12] in R/neutral; it's totally dissolved and soluble, meaning it can safely be used intravenously. [13]

The very small insulin particles in semilente insulin are suspended by zinc. [12] Semilente is cloudy, has an acetate buffer and cannot be used intravenously.

R/Neutral insulin cannot be reliably mixed with Lente or Ultralente insulins. [14][15] Semilente can; the ratio of 3 parts semilente insulin to 7 parts ultralente insulin produces Lente insulin. [12]
