Insulin Types and Information
Mixed or combination insulins
Mixed or combination insulins are where a shorter acting insulin is combined with a longer acting insulin.
On the plus side, this can mean less injections and can help to make dosages simpler. The disadvantage though, is that premixed insulins allow for less flexibility with tailoring your doses.
Common insulin products in the UK include the following:
- Humalog: Humalog is an Eli Lilly product, with the active ingredient insulin lispro. It is extremely rapid-acting, and will typically begin to work within 15 minutes.
- Lantus: Lantus is a long-acting analogue insulin. Typically Lantus is administered to the body once every day.
- Levemir: Levemir is also a long-acting analogue insulin. Levemir tends to have a slightly shorter duration than Lantus and therefore it is often taken twice daily.
- Novorapid: The active ingredient in Novorapid is insulin aspart. When novorapid is injected, it is extremely fast-acting, and works rapidly to normalise blood sugar levels. It typically begins working after 10-20 minutes, and will last for between 3 and 5 hours.
- Actrapid: Novo Nordisk did produce Actrapid preloaded pens, cartridges and vials for the UK insulin market. However, due to commercial reasons they have discontinued both the pens and cartridges as from January 2006.
- Humulin: Humulin insulins are human insulins made by Eli Lilly Co. Short acting, intermediate acting and premixed humulin insulins are available.
- Hypurin: Hypurin insulins are animal insulins produced by Wockhardt UK. They make short acting, intermediate and long acting insulins and are available in beef or pork insulin forms.
- Insuman: Insuman is another insulin type that comes in several different forms. Insuman basal is an intermediate-acting insulin with the active ingredient isophane insulin.
- Insulatard: Insulatard, manufactured by Novo Nordisk, comes in preloaded pens (Novojet, InnoLet, Flexpen), penfill cartridges and vials based around the active ingredient human isophane insulin.
