Clonidine lowers blood pressure by decreasing the levels of certain chemicals in your blood. This allows your blood vessels to relax and your heart to beat more slowly and easily. The Catapres brand of clonidine is used to treat hypertension (high blood pressure). The Kapvay brand is used to treat attention deficit hyperactivity disorder (ADHD). Clonidine is sometimes given with other medications. Before you take clonidine, tell your doctor if you have heart disease or severe coronary artery disease, a heart rhythm disorder, slow heartbeats, low blood pressure, a history of heart attack or stroke, kidney disease, or if you have ever had an allergic reaction to a Catapres TTS transdermal skin patch. You should not take this medicine if you are allergic to clonidine. Adults, including the elderly: In hypertensive crises 150 to 300 micrograms (1 to 2 ampoules) should be given by slow intravenous injection. This dose may be repeated up to a maximum of 750 micrograms (5 ampoules) in a 24 hour period. Patients undergoing anaesthesia should continue their Catapres treatment before, during and after anaesthesia using oral or intravenous administration according to individual circumstances. Intravenous injection of Catapres should be given slowly over 10-15 minutes to avoid a possible transient pressor effect. Catapres injection solution is compatible with 0.9% sodium chloride solution and with 5% Dextrose solution. Paediatric Population: There is insufficient evidence for the application of clonidine in children and adolescents younger than 18 years. Therefore the use of clonidine is not recommended in paediatric subjects under 18 years.
Clonidine, sold as the brand name Catapres among others, is a medication used to treat high blood pressure, attention deficit hyperactivity disorder, drug withdrawal (alcohol, opioids, or smoking), menopausal flushing, diarrhea, and certain pain conditions. Clonidine is used to treat high blood pressure, attention deficit hyperactivity disorder (ADHD), drug withdrawal (alcohol, opioids, or smoking), menopausal flushing, diarrhea, and certain pain conditions. It can alleviate opioid withdrawal symptoms by reducing the sympathetic nervous system response such as tachycardia and hypertension, as well as reducing sweating, hot and cold flashes, and general restlessness. Clonidine also has several off-label uses, and has been prescribed to treat psychiatric disorders including stress, sleep disorders, and hyperarousal caused by post-traumatic stress disorder, borderline personality disorder, and other anxiety disorders. Clonidine has also been used to treat refractory diarrhea associated with irritable bowel syndrome, fecal incontinence, diabetes, withdrawal-associated diarrhea, intestinal failure, neuroendocrine tumors and cholera. The reduction in circulating norepinephrine by clonidine was used in the past as an investigatory test for phaeochromocytoma, which is a catecholamine-synthesizing tumour, usually found in the adrenal medulla. In a clonidine suppression test plasma catecholamine levels are measured before and 3 hours after a 0.3 mg oral test dose has been given to the patient. It crosses the blood-brain barrier and acts in the hypothalamus to induce a decrease in blood pressure. It may also be administered as an epidural infusion as an adjunct treatment in the management of severe cancer pain that is not relieved by opiate analgesics alone. Clonidine may be used for differential diagnosis of pheochromocytoma in hypertensive patients. Other uses for clonidine include prophylaxis of vascular migraine headaches, treatment of severe dysmenorrhea, management of vasomotor symptoms associated with menopause, rapid detoxification in the management of opiate withdrawal, treatment of alcohol withdrawal used in conjunction with benzodiazepines, management of nicotine dependence, topical use to reduce intraocular pressure in the treatment of open-angle and secondary glaucoma and hemorrhagic glaucoma associated with hypertension, and in the treatment of attention-deficit hyperactivity disorder (ADHD).
The authors studied the effects of epidural clonidine (300 micrograms) on circulation and ventilatory control in seven healthy unpremedicated subjects. After clonidine injection, arterial blood pressure decreased significantly in all subjects (range, 13%-25% for systolic blood pressure and 13%-32% for diastolic blood pressure). Heart rate decreased significantly by 10%-16% between 75 and 105 min after injection. The slope of the ventilatory response to CO2 decreased significantly from 2.06 /- 0.70 (baseline) to 1.37 /- 0.68, 1.25 /- 0.65, and 1.33 /- 0.67 L.min-1Hg-1 (mean /- SD, P less than 0.05) at 15, 60, and 120 min. The authors conclude that epidural clonidine induces mild ventilatory and circulatory depression.

All medicines have benefits and risks. Your doctor has weighed the risks of you using the MZ Clonidine HCl Injection against the benefits they expect it will have. Sep 15, 2014. This research will study and compare the effectiveness, if any, of clonidine compared to steroid in an epidural injection for low back pain.
