• Tested negative at the screening visit for the following drug screen panel (barbiturates, benzodiazepines, amphetamines, opiates, cocaine, cannabinoids). Unless known drugs were being used for medicinal reasons. For this reason the sponsor and investigator were notified

• History of drug addiction or alcoholism
• Any medical or psychological condition which could relapse during or immediately after the study
• Use of any drug or nutrient which could induce or inhibit hepatic microsomal enzymes within one month of the start of the study or longer based on the elimination half-life of the drug

• Coffee or tea consumption > 3 cups per day or xanthine containing drinks > 0.5 liter/day
• History of any clinically significant hematological, respiratory, cardiovascular, renal or CNS disease or other medical condition (except hepatic impairment) that is capable of altering the metabolism or elimination of drugs, or of constituting a risk factor when taking the study drug
