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). 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.

Calculate the percentage of each impurity in the Clonidine taken by the formula 5C / Wr i / r S, At the beginning of the 1960s Boehringer Ingelheim planned to synthesize a peripherally active adrenergic compound for nasal decongestion as simple nose drops. Imidazoline-derivatives with decongestive properties are substituted amidines in which the amidine function is incorporated into an imidazoline structure. However, at that time a replacement of the –CH– bridge by an –NH– group had not been achieved chemically in compounds substituted at both the 2- and 6-positions of the phenyl ring. The problem was solved by introducing chlorine atoms as substituents. Although the resulting drug indeed had a remarkably high vasoconstructive and decongestive effect at low concentrations, it turned out that other effect were more significant. After administration of the drug to a secretary she fell asleep for 24 h, developed low blood pressure, marked bradycardia, and dryness of the mouth. Clonidine was subsequently developed for its blood-lowering effect and introduced into the clinical routine in 1966. Conidine is a drug which is primarily used as an antihypertensive agent, however it now sees widespread use in a number of other fields eg as an additive to anaesthetics. Two of the most interesting uses for the drug though are in the treatment of alcohol and nicotine withdrawl and in the treatment of ADD (Attention Deficit Disorder). For the treatment of ADD it has been found to reduce hyperactivity especially in children. However, tolerance can develop for the drug and can lead to withdrawl symptoms when taken off the drug. It is usually necessary to continue taking the drug for some time after the condition for which it was prescribed has been cured. Clonidine is delivered as Clonidinehydrochloride and is an imidazoine derivative and a mesomeric compound. When administered clonidine is transported by lipids by bonding to albumin.
