• •Concomitant therapy with any antihypertensive medications, including those used for indications other than hypertension (e.g., diuretics for any reason, minoxidil for hair loss, propranolol HCl for migraine, terazosin HCl for benign prostatic hyperplasia, 5-phosphodiesterase inhibitors (Viagra, Cialis, Levitra) within 48 hours of clinic visit, ACE-inhibitors for congestive heart failure, or any agent which could cause a change in blood pressure), except for stable doses of NSAIDs, or tricyclic agents taken at bedtime. Patients who are unwilling to discontinue these medications or patients in whom the Investigator feels it is clinically inappropriate to discontinue these medications should not participate in the study
• •Concomitant therapy with lithium and/or major psychotropic agents such as phenothiazines
• •Concomitant therapy with oral steroids or ACTH

• •Concomitant therapy with any vitamin supplement that may contain pyridoxine or pyridoxine derivative such as pyridoxal phosphate or pyridoxal
• •Hypertension induced by oral contraceptives. Replacement hormones (thyroid, testosterone, estrogens) are permitted if the patient has been on a stable dose for at least three months

• •Myocardial infarction, percutaneous coronary intervention and coronary artery bypass surgery within 6 months prior to screening
• •Clinically significant AV conduction disturbance, i.e., second or third degree AV block, sick sinus syndrome or clinically significant bradycardia (resting heart rate \< 60 beats/minute) without a permanent pacemaker
• •Presence of atrial flutter or atrial fibrillation
• •Potentially life-threatening ventricular arrhythmias, decompensated valvular disease, presence of hemodynamically significant obstructive valvular disease, or cardiomyopathy
• •Serum potassium \< 3.5 or \> 5.5 mEq/L
• •The presence of severe hepatic impairment as manifested by AST (SGOT) \> 2.5 times the upper limit of normal or ALT (SGPT) \> 2.5 times the upper limit of normal
• •Any clinically significant laboratory value which in the Investigator's judgement could be clinically significant to the outcome of this study. This includes, but is not limited to, hematocrit, haemoglobin or platelet count
• •Any moderate to severe renal impairment, as manifested by serum creatinine more than 200 micromol/L
• •A history of clinically important gastrointestinal resection, malabsorption or cirrhosis of the liver
• •Any concurrent severe disease that, in the Investigator's judgement, could preclude participation or survival
• •Use of any investigational drug or device, or participation in any drug study during or within 30 days prior to baseline
