How is it used?

Protaphane is given subcutaneously (under the skin) by injection, usually in the thigh. If convenient it may also be given in the abdominal wall (tummy), the gluteal region (buttocks) or the deltoid region (shoulder). The patient's blood glucose (sugar) should be tested regularly to find the lowest effective dose. Protaphane is a long-acting insulin, it can be given as a once- or twice-daily injection, with or without a fast-acting insulin (at meal times), according to the doctor?s recommendation.

How does it work?

Diabetes is a disease in which the body does not produce enough insulin to control the blood glucose. Protaphane is a replacement insulin which identical to the insulin made by the pancreas. The active substance in Protaphane, insulin human (rDNA), is produced by a method known as ?recombinant technology?: The insulin is made by a yeast that has received a gene (DNA), which makes it able to produce insulin. Protaphane contains insulin mixed with another substance, protamine, in an ?isophane? form which is absorbed much more slowly during the day. This gives Protaphane a longer duration of action. The replacement insulin acts in same way as naturally produced insulin and helps glucose enter cells from the blood. By controlling the blood glucose, the symptoms and complications of diabetes are reduced.

How has it been studied?

Protaphane has been studied in four main clinical trials, which included a total of 557 patients with type 1 diabetes,when the pancreas cannot produce insulin (two studies involving 81 patients), or type 2 diabetes, when the body is unable to use insulin effectively (two studies involving 476 patients). In most patients, Protaphane was compared with other types of human insulin or insulin analogues. The studies measured the level of fasting blood glucose or a substance in the blood called glycosylated haemoglobin (HbA1c), which gives an indication of how well the blood glucose is controlled. Further studies were also carried out in 225 patients comparing injecting Protaphane using a syringe, or using a pre-filled pen (InnoLet, NovoPen or FlexPen).

What benefits has it shown during the studies?

Protaphane led to a decrease in the level of HbA1c, indicating that blood sugar levels had been controlled to a similar level to that seen with other human insulin. Protaphane was effective for both type 1 and type 2 diabetes, and when using a standard injection or one of the pens.

What is the risk associated?

As with all insulins, Protaphane may cause hypoglycaemia (low blood glucose). For the full list of all side effects reported with Protaphane, see the Package Leaflet.
Protaphane should not be used in people who may be hypersensitive (allergic) to insulin human (rDNA) or to any of the other ingredients. Protaphane doses might also need to be adjusted when given with a number of other medicines which may have an effect on blood glucose. The full list is available in the Package Leaflet.

Why has it been approved?

The Committee for Medicinal products for Human Use (CHMP) decided that Protaphane?s benefits are greater than its risks for the treatment of diabetes. The Committee recommended that Protaphane be given marketing authorisation.
