clonidine and Malignant Hypertension

clonidine has been researched along with Malignant Hypertension in 27 studies

Clonidine: An imidazoline sympatholytic agent that stimulates ALPHA-2 ADRENERGIC RECEPTORS and central IMIDAZOLINE RECEPTORS. It is commonly used in the management of HYPERTENSION.
clonidine (amino form) : A clonidine that is 4,5-dihydro-1H-imidazol-2-amine in which one of the amino hydrogens is replaced by a 2,6-dichlorophenyl group.

Trial Outcomes

Change in Blood Pressure After Intrathecal Injection of Clonidine.

"Subjects baseline blood pressure (systolic blood pressure (SBP), and diastolic blood pressure (DBP)), and blood pressures after clonidine injection was compared against baseline to assess efficacy of clonidine in refractory hypertensive subjects. Subject's blood pressure was monitored continuously after intrathecal injection of clonidine until subjects blood pressure nadir and return to pre clonidine injection level. The mean value reported below are the average changes in blood pressure from baseline (pre clonidine injection) in both SBP and DBP during post clonidine injection blood pressure monitoring for 4 hours.~Blood pressure measurements were collected every 10 minutes for first hour after injection, and every 15 minutes after the first hour, up to 4 hours were averaged to report the change from baseline." (NCT01297335)
Timeframe: Baseline, Every 10 Minutes for first hour after clonidine injection, and every 15 minutes after first hour, until 4 hours after clonidine injection

Changes in Visual Analogue Scale (VAS) Ratings of Sedation and Sensation of Dry Mouth Reported by the Subjects, Pre and 1 Hour Post Injection

Subjects were asked to rate severity of two of the most common side effects of clonidine, sedation and sensation of dry mouth, at pre and post (1 hour after) intrathecal administration of clonidine. The mean changes between pre and post injection VAS ratings of sedation and sensation of dry mouth are reported below. The VAS scale ranges from 1 to 10 cm, with higher values indicating higher level of sedation and higher level of dry mouth. (NCT01297335)
Timeframe: Before clonidine injection (Baseline), and at 1 hour after clonidine injection.

Likert Scale Pain Rating

Likert scale is 11 point digital pain rating system that asks subjects to rate their pain from 0 to 10. Rating of 0 means no pain at all, and in increasing order, 10 would mean worst pain imaginable/ unbearable pain. (NCT01297335)
Timeframe: Pre-dose and 1 hour post injection.
