Humulin C time activity profile.
Humulin C is one of several brands of "Regular" (short-acting) insulin, used for a quick consumption of blood sugar with little delay. The "C" stands for corriente, which is Spanish for "regular" or "neutral". Though they are made from beef and from pork, the Beta Laboratorios two short-acting insulins have "corriente" in their names: Betasint Bovine Corriente and Betasint Porcine Corriente. Both are also short-acting insulins like Humulin C and have similar time activity profiles.
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:
- Novolin R [3]
- Humulin S [4][5][6]
- Huminsulin Normal
- Actrapid [7][8][9]
- Insuman Rapid [10][11].
- Winthrop Rapid
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 [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]
