Primary Outcome Measures:
  • P-Glucose levels [ Time Frame: Repeated sampling during the 24 hour period on day 5 and 8 ]

Secondary Outcome Measures:
  • Safety and tolerability (AE, BP, pulse, plasma glucose, laboratory variables, weight and ECG) [ Time Frame: Frequent measurements during the study period ]
  • Pharmacokinetic variables (Area under the plasma conc-time curve from time 0 to 24 hours post dose (AUC0-24), maximum plasma conc(Cmax), time to reach maximum plasma conc(tmax), terminal elimination half-life and apparent oral clearance [ Time Frame: Repeated sampling during the 24 hour period on day 5 and 8 ]
  • Pharmacodynamics (P-Glucose, S-Insulin and S-C-peptide) [ Time Frame: Repeated sampling during the 24 hour period on day 5 and 8 ]

Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: AZD1656

Drug: Glucagon
1 mg injected 3 hr post AZD1656 morning dose on day 5 alt. day 8
Experimental: 2 Drug: AZD1656
Dose titration of oral suspension during 2 days to a tolerable dose given twice daily. Subjects will thereafter be treated with this dose for another 6 days. On day 5 and 8 the dose will be given as a single dose
