Beskrivelse
Inclusion Criteria:
- Age 18-70 years
- Duration of Type 1 Diabetes ≥ 3 years
- Insulin pump use > 6 months
Exclusion Criteria:
- Use of anti-diabetic medicine (other than insulin), corticosteroids or other drugs affecting glucose metabolism during the study period or within 30 days prior to study start
- Allergy or intolerance to lactose or GlucaGen (Novo Nordisk, Bagsværd, DK)
- Use of medications that are known to cause QT interval prolongation
- Females who are pregnant, breast-feeding or intend to become pregnant or are not using adequate contraceptive methods
- Females who have different basal insulin pattern depending on their menstrual cycle
- Inability to understand the individual information and to give informed consent
- Current participation in another clinical trial that, in the judgment of the principle investigator, will compromise the results of the study or the safety of the subject
- Other concomitant medical or psychological condition that according to the investigator's assessment makes the individual unsuitable for study participation
