Kapvay

Kapvay, an imidazoline-derivative hypotensive agent is a centrally-acting α2-adrenergic agonist. 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. Kapvay may be used for differential diagnosis of pheochromocytoma in hypertensive patients. Other uses for kapvay 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 ). Kapvay also exhibits some peripheral activity.

Kapvay is an α-adrenergic agent that acts specifically on α2-receptors. α2-receptors regulate a number of signaling pathways mediated by multiple Gi proteins, Gαi1, Gαi2, and G&alphai3. Stimulation of α2-receptors mediates effects such as inhibition of adenylyl cyclase, stimulation fo phospholipase D, stimulation of mitogen-activated protein kinases, stimulation of K+ currents and inhibition of Ca2+ currents. Three G-protein coupled α2-receptor subtypes have been identified: α2A, α2B, and α2C. Each subtype has a unique pattern of tissue distribution in the central nervous system and peripheral tissues. The α2A-receptor is widely distributed throughout the central nervous system; it is found in the locus coeruleus, brain stem nuclei, cerebral cortex, septum, hypothalamus, and hippocampus. α2A-receptors are also expressed in the kidneys, spleen, thymus, lung and salivary glands. The α2C-receptor is primarily expressed in the central nervous system, including the striatum, olfactory tubercle, hippocampus and cerebral cortex. Low levels of the α2C-subtype are also found in the kidneys. The α2B-receptor is located primarily in the periphery (kidney, liver, lung and heart) with low levels of expression in the thalamic nuclei of the central nervous system. The α2A- and α2C-receptors are located presynaptically and inhibit the released of noradrenaline from sympathetic nerves. Stimulation of these receptors decreases sympathetic tone, resulting in decreases in blood pressure and heart rate. Sedation and analgesia is mediated by centrally located α2A-receptors, while peripheral α2B-receptors mediate constriction of vascular smooth muscle. α2A-Receptors also mediate essential components of the analgesic effect of nitrous oxide in the spinal cord. Kapvay stimulates all three α2-receptor subtypes with similar potency. Its actions in the nervous system decreases blood pressure in patients with hypertension and decreases sympathetic overactivity in patients undergoing opioid withdrawal. Kapvay is also a potent sedative and analgesic and can prevent post-operative shivering in intensive and post-operative care. Its use in differential diagnosis of pheochromocytoma owes to the fact that hypertension in patients with pheochromocytoma is refractory to antihypertensive treatment with kapvay.

Oral LD50 is 150 mg/kg in rat and 30 mg/kg in dog. Symptoms of overdose include constriction of pupils of the eye, drowsiness, high blood pressure followed by a drop in pressure, irritability, low body temperature, slowed breathing, slowed heartbeat, slowed reflexes, and weakness.
