    Transcript
    Let's take a look at the profiles, of the different types of insulins that are on the market today. So the rapid acting insulins, sometimes called the ultra rapid acting insulins, are usually given at meal time. There is three different major groups of rapid acting insulins. There is the aspart insulin that peaks at 10 to 20 minutes, there is lispro insulin that peaks at 15 to 30 minutes, and there is glulisine insulin that will peak, a little bit later at about 20 to 30 minutes time. The short acting insulins take a little bit longer but they are still considered short acting. These are the oldest of the insulins, and we call them regular insulins. Trade names include Humulin and Novolin. They peak at around 30 minutes to 60 minutes and they last up to 4 to 12 hours. The intermediate insulins lasts generally in the 12 hour range. They peak at about 1 to 2 hours. We call them intermediate insulins, NPH insulins. The long acting insulins, are the newest insulins out there and they're really starting to become a mainstay of insulin therapy. Detemir insulin peaks around 60 to 90 minutes, and lasts about 24 hours. Glargine insulin doesn't really have a peak time, or at least that's what the marketing information says. There is a bit of a spike at around 3 or 4 hours, but it's not really a clinically relevant spike, it's only relevant on a pharmacology chart, but from a practical point of view, it doesn't really have a peak time and it also lasts about 24 hours. There are actually new insulins out there, that are super long acting insulins that now lasts about 36 to 48 hours, and we will briefly mention them today. As time goes on, they...
