Inclusion Criteria: 1. Refractory hypertension, defined as a SBP of >140mmHg and a DBP > 90mmHg, on stable doses of at least 3 concomitant antihypertensive treatment (which must include a diuretic and an ACEI, ARB or RA) for 8 weeks prior to Screening. All approved antihypertensive treatments are allowed except for alpha-adrenergic blockers, hydralazine, clonidine, guanethidine, guanadrel, and rauwolfia alkaloids. 2. Stable hypertension, as defined by: a. mean SBP on Day -7 that is within 20mmHg of the mean SBP on Day 1, with both mean SBPs > 140mmHg; and b. mean DBP on Day -7 that is within 10mm of the mean DBP on Day 1, with both mean DBPs > 90mmHg. 3. Outpatient with stable housing. 4. Subjects must be able to stay in the clinic for 8 hrs on Day 1, Day 8, Day 15, Day 22, and Day 36. 5. Able to give and to sign informed consent. Exclusion Criteria: 1. Any unstable medical condition other than hypertension; 2. Stage 3 hypertension (SBP > 180mmHg and/or DBP > 110mmHg); 3. Heart rate > 100 beats per minute; 4. WOCBP who is pregnant or who is planning to become pregnant during the study; 5. History within past year of alcohol or illicit drug abuse; 6. Unable to comply with study procedures in opinion of investigator; 7. Concomitant medications for any medical condition that is uncontrolled for more than 2 weeks prior to study entry; 8. Current use of alpha-adrenergic blocker, hydralazine, clonidine, guanethidine, guanadrel, or rauwolfia alkaloids; 9. History of myocardial infarction or angina pectoris; 10. Current seizure disorder; 11. Renal insufficiency as defined by a serum creatinine > 2.0; 12. Uncontrolled hypothyroidism, vitamin B12 or folic acid deficiency; 13. History of or concurrent ileus, glaucoma, or urinary retention; 14. Inability of subject to understand and sign the ICF; 15. Known systemic infection (HBV, HCV, HIV, TB); 16. Current use of smoking cessation therapy within 4 weeks of screening; 17. Use of herbal supplements; 18. Clinically significant finding on physical exam; 19.

Body weight < 100 pounds. 23. Site staff or family member of study site staff. |
