• Status: Completed
• Trial end date: 2014-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Study primary Objective:

• To evaluate the bioequivalent rate (Cmax) and extent (AUC0-t) of absorption of N-acetyl-cysteine 600 mg uncoated tablets vs. N-acetyl-cysteine 600 mg film-coated tablets (NAC) in healthy male and female volunteers.

Study secondary objectives:

• to collect safety and tolerability data after single dose administration of NAC 600 mg uncoated tablets vs. NAC 600 mg film-coated tablets.

• Phase: Phase 1
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers
