• Body mass within 10% of the ideal mass in relation to height and age, according to the Body Mass Index (BMI).
• Body mass not less than 60 kg.
• Findings within the range of clinical acceptability in medical history and physical examination, and laboratory results within the "normal ranges" for the relevant laboratory tests (unless the investigator considered the deviation to be irrelevant for the purpose of the study).
• Normal electrocardiogram (ECG) and vital signs, or abnormalities which the investigator did not consider a disqualification for participation in the study.
• Willingness to undergo a pre-study physical examination and pre- and post-study laboratory investigations.
• Ability to comprehend and willingness to sign both statements of informed consent (for screening and phase-related procedures).

• was of childbearing potential, and all of the following conditions were met:

• had a normal menstrual flow within 1 month before study entry, and
• had negative serum pregnancy test at screening. If this test was positive, the subject was to have been excluded from the study before receiving study medication. In the rare circumstance that a pregnancy was discovered after the subjects received study drug, then every attempt must be made to follow such subjects to term, and
• must agree to use an accepted method of contraception (i.e., spermicide and barrier methods or spermicide and Intrauterine Device (IUD)). The subject had to agree to continue with the same method throughout the study. Hormonal contraceptives will not be allowed.

Exclusion Criteria

• History of, or current compulsive alcohol abuse (>10 drinks weekly), or regular exposure to other substances of abuse.
• Use of any medication, prescribed or over-the-counter, within 2 weeks prior to the first administration of study medication except if this would not have affected the outcome of the study in the opinion of the clinical investigator. Use of hormonal contraceptive agents by females were not allowed.
• Participation in another study with an experimental drug within 8 weeks before the first administration of study medication.
• Treatment within the previous 3 months with any drug with a well-defined potential for adversely affecting a major organ or system with evidence to this effect.
• A major illness during the 3 months before commencement of the screening period.
• History of hypersensitivity to the study drug or any related drugs.
• History of bronchial asthma.
• History of epilepsy.
• Relevant history or laboratory or clinical findings indicative of acute or chronic disease, likely to influence study outcome.
• Donation or loss of blood equal to or exceeding 500 mL during the 8 weeks before the first administration of study medication.
• Diagnosis of hypotension made during the screening period.
• Diagnosis of hypertension made during the screening period or current diagnosis of hypertension.
• Resting pulse of >100 beats per minute or <45 beats per minute during the screening period, either supine or standing.
• Positive testing for hepatitis B antigen.
• Significant liver disease, defined as active hepatitis or elevated liver enzymes (e.g., AST (aspartate aminotransferase), Alanine transaminase (ALT)) >2 times the upper boundary of the normal range.
• Positive urine screen for drugs of abuse.
• Positive urine screen for tobacco use (SureStepTM Smoke Check Tests and One-Step Cotinine (COT) Tests).
• A serum pregnancy test (beta-hCG) either positive or not performed or lactation.
• History of marijuana, barbiturate, amphetamine or narcotic abuse within 12 months prior to study start.
