Read all of this leaflet carefully before you start using this medicine because it contains important information for you. Your doctor will discuss with you what other form of birth control would be more appropriate. If you are not sure, talk to your doctor, pharmacist or nurse before using this medicine. Warnings and precautions Before using this medicine, you will need to see your doctor for a medical check-up. If you are unsure, talk to a doctor as some of these symptoms such as coughing or being short of breath may be mistaken for a milder condition such as a respiratory tract infection. Sometimes the symptoms of stroke can be brief with an almost immediate and full recovery, but you should still seek urgent medical attention as you may be at risk of another stroke. Most frequently, they occur in the first year of use of a combined hormonal contraceptive. The risk of developing a blood clot in a vein is highest during the first year of taking a combined hormonal contraceptive for the first time. The risk may also be higher if you restart taking a combined hormonal contraceptive (the same product or a different product) after a break of 4 weeks or more. After the first year, the risk gets smaller but is always slightly higher than if you were not using a combined hormonal contraceptive. Air travel (> 4 hours) may temporarily increase your risk of a blood clot, particularly if you have some of the other factors listed. It is important to tell your doctor if any of these conditions apply to you, even if you are unsure. If you have more than one of these conditions or if any of them are particularly severe the risk of developing a blood clot may be increased even more. If you experience mood changes and depressive symptoms contact your doctor for further medical advice as soon as possible. This may help prevent you from getting these spots or help prevent them from getting worse. These include chlamydia, genital herpes, genital warts, gonorrhoea, hepatitis B, syphilis. Your doctor will prescribe another type of contraceptive prior to start of the treatment with these medicinal products. The interfering effect of some of these medicines can last for up to 28 days after you have stopped taking them. If you think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Driving and using machines You can drive or use machines while using this medicine. Risks of using combined hormonal contraceptives the following information is based on information about combined birth control pills. All combined birth control pills have risks, which may lead to disability or death. Combined hormonal contraceptives and cancer Cervical cancer Cervical cancer has been found more often in women taking combined hormonal contraceptives. However, it is possible that the combined hormonal contraceptive is not the cause of more women having breast cancer. It may be that women taking the combined hormonal contraceptive are examined more often. The increased risk gradually goes down after stopping the combined hormonal contraceptive. After 10 years, the risk is the same as for people who have never used the combined hormonal contraceptive. Liver cancer In rare cases, liver tumours which are not cancer have been found in women taking combined hormonal contraceptives.

Anomia occurs with pathologies affecting the left temporoparietal area, but since it occurs in all varieties of aphasia is of little precise localizing or diag nostic value. The term anomic aphasia is reserved for unusual cases in which a naming problem overshadows all other deficits. Anomia may often be seen as a residual deficit following recovery from other types of aphasia. Rhinological disease (allergic rhinitis, coryza) is by far the most com mon cause; this may also account for the impaired sense of smell in smokers. Head trauma is the most common neurological cause, due to shearing off of the olfactory fibres as they pass through the cribriform plate. Recovery is possible in this situation due to the capacity for neuronal and axonal regeneration within the olfactory pathways. Cross References Age-related signs; Ageusia; Cacosmia; Dysgeusia; Mirror movements; Parosmia Anosodiaphoria Babinski (1914) used the term anosodiaphoria to describe a disorder of body schema in which patients verbally acknowledge a clinical problem. Anosognosia with hemiplegia most commonly follows right hemisphere injury (parietal and temporal lobes) and may be associated with left hemine glect and left-sided hemianopia; it is also described with right thalamic and basal ganglia lesions. Many patients with posterior aphasia (Wernicke type) are unaware that their output is incomprehensible or jargon, possibly through a fail ure to monitor their own output. The completion phenomenon: insight and attitude to the defect: and visual function efficiency. Apathy is also described following amphetamine or cocaine with drawal, in neuroleptic-induced akinesia and in psychotic depression. Language may be defined as the complex system of symbols used for communication (including reading and writing), encompassing various linguis tic components (phonetic, phonemic, semantic/lexical, syntactic, pragmatic), all of which are dependent on dominant hemisphere integrity. Language is dis tinguished from speech (oral communication), disorders of which are termed dysarthria or anarthria. These features allow definition of various types of aphasia (see table and specific entries; although it should be noted that some distinguished neurol ogists have taken the view that no satisfactory classification of the aphasias exists (Critchley)). Conduction aphasia is marked by relatively normal spontaneous speech (perhaps with some paraphasic errors), but a profound deficit of repetition. In transcortical motor aphasia spontaneous output is impaired but repetition is intact. Cross References Anarthria; Aphasia; Aprosodia, Aprosody; Dysarthria; Phonemic disintegra tion; Speech apraxia Aphonia Aphonia is loss of the sound of the voice, necessitating mouthing or whispering of words. Aphonia should be differentiated from mutism, in which patients make no effort to speak, and anarthria in which there is a failure of articulation. Cross Reference Aphasia Apraxia Apraxia or dyspraxia is a disorder of movement characterized by the inability to perform a voluntary motor act despite an intact motor system. They probably represent a disturbance of attention or concentration, rather than being a harbinger of dementia. Cross References Attention; Dementia Aprosodia, Aprosody Aprosodia or aprosody (dysprosodia, dysprosody) is a defect in or absence of the ability to produce or comprehend speech melody, intonation, cadence, rhythm, and accentuations, in other words the non-linguistic aspects of language which convey or imply emotion and attitude. Cross References Retinopathy; Scotoma Arefiexia Arefiexia is an absence or a loss of tendon refiexes. Since the light refiex is lost, testing for the accommodation reaction may be performed with the pupil directly illuminated: this can make it easier to see the response to accommodation, which is often dif ficult to observe when the pupil is small or in individuals with a dark iris. Although pupil involvement is usually bilateral, it is often asymmetric, causing anisocoria. The term was invented in the nineteenth century (Hamilton) as an alternative to aphasia, since in many cases of the latter there is more than a loss of speech, including impaired pantomime (apraxia) and in symbolizing the relationships of things. Hughlings Jackson approved of the term but feared it was too late to displace the word aphasia. The neuroanatomical correlate of asomatognosia is damage to the right supramarginal gyrus and posterior corona radiata, most commonly due to a cerebrovascular event. The predilection of asomatognosia for the left side of the body may simply be a refiection of the aphasic problems associated with left sided lesions that might be expected to produce asomatognosia for the right side. The term has no standardized definition and hence may mean different things to different observers; it has also been used to describe a disorder characterized by inability to stand or walk despite nor mal leg strength when lying or sitting, believed to be psychogenic (although gait apraxia may have similar features). Cross Reference Gait apraxia Astereognosis Astereognosis is the failure to recognize a familiar object, such as a key or a coin, palpated in the hand with the eyes closed, despite intact primary sensory modal ities. There may be associated impairments of two-point discrim ination and graphaesthesia (cortical sensory syndrome). Some authorities recommend the terms stereoanaesthesia or stereohypaes thesia as more appropriate descriptors of this phenomenon, to emphasize that this may be a disorder of perception rather than a true agnosia (for a similar debate in the visual domain, see Dysmorphopsia). Asynergia Asynergia or dyssynergia is lack or impairment of synergy of sequential muscular contraction in the performance of complex movements, such that they seem to become broken up into their constituent parts, so-called decomposition of move ment. Cross References Ataxia; Cerebellar syndromes; Dysarthria; Dysdiadochokinesia; Dysmetria; Scanning speech Ataxia Ataxia or dystaxia refers to a lack of coordination of voluntary motor acts, impairing their smooth performance. Sensory loss is an indica tor of capsular involvement; pain in the absence of other sensory features is an indicator of thalamic involvement. Clinically there is a marked discrepancy between heteroactivation, behaviour under the infiuence of exogenous stimulation, which is normal or almost normal, and autoactivation. Athymhormia is thus environment-dependent, patients nor malizing initiation and cognition when stimulated, an important differentiation from apathy and akinetic mutism. The term is often applied to wasted muscles, usually in the context of lower motor neurone pathology (in which case it may be synonymous with amyotrophy), but also with disuse. Atrophy develops more quickly after lower, as opposed to upper, motor neurone lesions. Cross Reference Dementia Attention Attention is a distributed cognitive function, important for the operation of many other cognitive domains; the terms concentration, vigilance, and per sistence may be used synonymously with attention. This agnosia may be for either verbal material (pure word deafness) or non verbal material, either sounds (bells, whistles, animal noises) or music (amusia, of receptive or sensory type). This may be equivalent to noise induced visual phosphenes or sound-induced photisms.

Her appetite is unchanged and normal, she has no nausea or vomiting, but over the last 2 months she has had an altered bowel habit with constipation alternating with her usual and normal pattern. No lymphadenopathy is detected, and her breasts, thyroid, heart, chest and abdomen, including rectal examination, are all normal. A barium enema revealed a neoplasm in the sigmoid colon, con firmed by colonoscopy and biopsy. Chest X-ray and abdominal ultrasound showed no pul monary metastases and no intra-abdominal lymphadenopathy or hepatic metastases respectively. She proceeded to a sigmoid colectomy and end-to-end anastamosis, and was regularly followed-up for any evidence of recurrence. Rectal bleeding, alteration in bowel habit for longer than 1 month at any age, or iron-deficient anaemia in men or postmenopausal women are indi cations for investigation of the gastrointestinal tract. During the last 3 months he has had intermit tent nausea, especially in the mornings, and in the last 3 months the morning nausea has been accompanied by vomiting on several occasions. He has been a chef all his working life, without exception in fashionable restaurants. The cause is likely to be alcohol as it is a common cause of this problem, he is at increased risk through his work in the catering business. However his alcohol intake is too low to be consistent with the diagnosis of alcoholic liver disease. The slight reductions in the sodium and urea reflect a chronic reduced intake of salt and protein; the rise in bilirubin is insufficient to cause jaundice. Further investigations are the measurement of hepatitis viral serology, which was nega tive, and an ultrasound of the abdomen. A liver biopsy, performed to confirm the diagnosis, assess the degree of histological damage and exclude other pathology, showed changes of cirrhosis. The crucial aim in management is to impress upon the patient the necessity to stop drink ing alcohol, in view of the degree of liver damage, the presumed portal hypertension and the risk of oesophageal varices and bleeding, and to effect this by his attending an alco hol addiction unit. In the short term he should also improve his diet to increase his pro tein intake. Diuretics could be used to reduce his oedema, but it should be remembered that they could cause postural hypotension more easily against this background. His attendance at the addiction unit was fitful, he continued to drink heavily and he died 3 years later as a result of a second bleed from oesophageal varices. For 2 weeks he has had aching pains in the knees, elbows and wrists without any obvious swelling of the joints. He has taken marijuana and ecstasy occa sionally over the past 2 years and various tablets and mixtures at clubs without being sure of the constituents. He has had irregular homosexual contacts but says that he has always used protection. There are no abnor malities to find on examination of the joints or in any other system. The biochemical results show abnormal liver function tests with a predominant change in the transaminases, indicating a hepato cellular rather than an obstructive problem in the liver. Homosexuality and intra venous drug abuse are risk factors for hepatitis B and C. Other viral infections such as cytomegalovirus and herpes simplex virus are possible. Since the drug ingestion history is unclear, there is a possibility of a drug-induced hepatitis. The prodromal joint symptoms suggest a viral infection as the cause, and this is more com mon with hepatitis B. Serological tests can be used to see whether there are immunoglobu lin M (IgM) antibodies indicating acute infection with one of these viruses, to confirm the diagnosis. The prothrombin time in this patient is raised slightly but not enough to be an anxiety or an indicator of very severe disease. Liver function will need to be measured to monitor enzyme levels as a guide to progress. Alcohol and any other hepatotoxic drug intake should be avoided until liver function tests are back to normal. If hepatitis B or C is confirmed by serology then liver function tests and serological tests should be monitored for chronic disease, and antiviral therapy then considered. Rare complications of the acute illness are fulminant hepatic failure, aplastic anaemia, myocarditis and vasculitis. The opportunity should be taken to advise him about the potential dangers of his intake of cigarettes, drugs and alcohol, and to offer him appropriate support in these areas. She has been hyper tensive for 20 years and has been on antihypertensive medication for that time. Her pulse is 88/min regular, blood pressure 190/110 mmHg; mild pitting oedema of her ankles is present. Neurological examination shows a left upper motor neurone facial palsy with mild weakness and increased reflexes in the left arm and leg. The elevated urea and creatinine levels confirm renal failure but do not distinguish between acute and chronic renal failure. Usually, in the former, there is either evidence of a systemic illness or some other obvious precipitating cause. If the patient has had previous blood tests measuring serum creatinine, these will be informative about the progression of deterioration of renal function. In this patient, the anaemia and hyperparathyroidism (raised alkaline phosphatase) are features indicating chronicity of the renal failure. The normochromic, normocytic anaemia is predominantly due to erythropoietin deficiency (the kidney is the major source of erythropoietin produc tion). Hyperparathyroidism is a result of elevated serum phosphate levels due to decreased renal clearance of phosphate and reduced vitamin D levels (the kidney is the site of hydrox ylation of 25-hydroxycholecalciferol to the active form 1,25-dihydroxycholecalciferol). A hand X-ray showing the typical appearances of hyperparathyroidism (erosion of the ter minal phalanges and subperiosteal erosions of the radial aspects of the middle phalanges), implying long-standing renal failure can be helpful in distinguishing chronic and acute renal failure. Ultrasound will accurately size the kidneys, and identify obvious causes for renal failure such as polycystic kidney disease or obstruc tion causing bilateral hydronephrosis. In this case, ultrasound showed two small (8 cm) echogenic kidneys consistent with long-standing renal failure. A renal biopsy in this case is not appropriate as biopsies of small kidneys have a high incidence of bleeding compli cations, and the sample obtained would show extensive glomerular and tubulo-interstitial fibrosis and may not identify the original disease. African Caribbeans are more prone to develop hypertensive renal failure than other racial groups. Antihypertensive medications are needed to treat her blood pressure adequately, oral phos phate binders and vitamin D preparations to control her secondary hyperparathyroidism, and erythropoietin injections to treat her anaemia. Hospital-based haemodialysis or home-based peri toneal dialysis are the options available. She became unwell 2 days previously when she started to develop a fever and an ache in her back. She has had no previous significant medical history, apart from an uncomplicated episode of cystitis 3 months ago. Acute pyelonephritis is much more common in women than men, and occurs due to ascent of bacteria up the urin ary tract. Pregnancy, diabetes mellitus, immunosuppression and structurally abnormal uri nary tracts increase the likelihood of ascending infection. Differential diagnosis Pyelonephritis causes loin pain which can be unilateral or bilateral. The differential diagnoses of loin pain include obstructive uropathy, renal infarction, renal cell carcinoma, renal papillary necrosis, renal calculi, glomerulonephritis, polycystic kidney disease, medullary sponge kidney and loin-pain haematuria syndrome.

Administering the copper sulfate in an orange-flavored drink increased the threshold for nausea to 8 ppm (0. Abdominal pain, nausea, and/or vomiting were observed in women drinking water containing 5 ppm (0. The occurrence of gastrointestinal effects (excluding diarrhea) was not significantly different in subjects ingesting copper sulfate and those ingesting copper oxide. The incidences of nausea, vomiting, and/or abdominal pain were 5, 2, 17, and 15% in the control, 1, 3, and 5 ppm groups, respectively. As analyzed using the chi-square test with Bonferroni correction, the incidence was significantly elevated in the 6 ppm (0. Recurrent, acute symptoms, including nausea, vomiting, and abdominal pain, were reported by three of four family members shortly after drinking juice, coffee, or water in the morning. The occurrence of vomiting and nausea with abdominal pain was not significantly different among residents with a first-draw water sample of 3 ppm or higher, as compared to controls with less than 1. The investigators noted that in a case-control study of this population, all of the cases reported that none of the subjects obtained their water immediately from the tap, but most (70%) only let it run for less than 1 minute. The study found that copper content in the tap water used for drinking averaged 14% of first draw samples. Most of the available human studies examined the relationship between copper exposure and the manifestation of symptoms of gastrointestinal irritation; Gotteland et al. As with gastric permeability, this effect was independent of gastrointestinal symptoms. No gastrointestinal effects were observed in rats and mice exposed to 23 or 92 mg Cu/kg/day for 14 days or in rats and mice exposed to 16 or 126 mg Cu/kg/day 13 weeks. Acute hemolytic anemia was observed in an 18-month-old child 2 days after he drank a solution containing approximately 3 g of copper sulfate (Walsh et al. Acute intravascular hemolysis was also reported in 5 of 125 individuals intentionally ingesting a large dose of copper sulfate (Ahasan et al. No alterations in hematocrit level or mean corpuscular volume were observed in individuals ingesting 0. Information on the hematological effects in animals associated with exposure to high levels of copper is also limited to several studies that measured hemoglobin and hematocrit values. Contrary to these findings, Liu and Medeiros (1986) observed an increase in hemoglobin levels and no change in hematocrit levels in rats fed a diet containing 14 mg Cu/kg/day as copper carbonate for 20 weeks. No studies were located regarding musculoskeletal effects in humans following oral exposure to copper. Equivocal results on the effects of copper on the musculoskeletal system have been found. Using radiographic data, no qualitative or quantitative differences were observed in bones of rats exposed to 120 mg Cu/kg/day as copper acetate in the diet for 21 weeks (Llewellyn et al. The different outcomes may reflect the different methods used to assess skeletal growth. In a compilation of case reports of individuals intentionally ingesting copper sulfate, jaundice was reported in 11 of 53 individuals (Chuttani et al. Centrilobular necrosis, biliary stasis, elevated serum bilirubin level and aspartate aminotransferase activity, and elevated bile salts in the urine were found in five of the individuals with jaundice. No alterations in biomarkers of liver damage (serum aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transferase) were observed in adults exposed to 0. Several studies have examined liver function in infants exposed to elevated levels of copper in drinking water. A no adverse effect level for liver effects was identified in a study of infants (3 months of age at study initiation) exposed to 0. No alterations in total bilirubin levels or serum alanine aminotranferase, aspartate aminotransferase, or gamma-glutamyl transferase activities were found. The reasons for being withdrawn from the study were blood sampling refusal (eight infants in the copper group and two infants in the control group), protocol transgression (four infants in the copper group and no infants in the control group), and change of address (five infants in the copper group and one infant in the control group). It is characterized by high levels of copper in the liver and low levels of serum ceruloplasmin. Other features include high rates of parental consanguinity and up to 22% of siblings affected (Pandit and Bhave 1996; Tanner 1998). The hepatotoxicity of copper in animals has been described and investigated in a number of acute and intermediate-duration oral exposure studies. The majority of these studies used rats; a small number of studies used pigs and mice. The results of these studies were not considered relevant to healthy humans and will not be discussed. The earliest symptoms of hepatotoxicity in rats orally exposed to copper are increases in serum chemistry enzymes, particularly alanine aminotransferase and asparate aminotransferase (Epstein et al. Continued exposure or exposure to higher concentrations can result in inflammation, parenchymal cell hypertrophy, and hepatocellular necrosis (Aburto et al. At very high doses, chronic hepatitis (Haywood 1985; Haywood and Loughran 1985) has also been observed. The threshold for hepatoxicity in rats following intermediate-duration exposure appears to be between 8 16 mg Cu/kg/day. Severe hepatic damage (chronic hepatitis) has been observed in rats exposed to >550 mg Cu/kg/day as copper sulfate in the diet for 15 weeks (Haywood 1985; Haywood and Loughran 1985). The available rat hepatoxocity data, along with toxicokinetic data, suggest that there are three phases of copper toxicity in the rat. In the first phase, copper levels increase in the liver, with minimal to no damage to hepatic tissues. Thereafter, the copper levels in the liver begin to decrease and the parenchymal tissue begins to regenerate. For example, no adverse liver effects were observed in rats exposed to 640 mg Cu/kg/day as copper sulfate in the diet when this exposure was preceded by a 15-week exposure to 320 mg Cu/kg/day as copper sulfate in the diet. This is in contrast to the severe hepatocellular necrosis that was observed in animals exposed to a control diet for 15 weeks followed by a 3-week exposure to 640 mg Cu/kg/day (Haywood and Loughran 1985). At higher doses, the onset of the necrosis and regeneration occurred earlier as compared to lower doses. Additionally, there appears to be an upper limit of copper intake, which would induce copper tolerance; doses that exceed this level would result in permanent damage to the liver. Dietary exposure of rats to fi550 mg Cu/kg/day as copper sulfate for 15 weeks resulted in chronic hepatitis with no evidence of regeneration of parenchymal tissue (Haywood and Loughran 1985). It appears that rats and pigs are equally sensitive to high levels of copper in the diet or drinking water. In contrast, mice do not appear to be as sensitive to the hepatic toxicity of copper as rats. Congestion of the glomeruli and denudation of tubular cells were observed in four individuals consuming a single lethal dose of copper sulfate (Chuttani et al. Acute renal failure was reported in 5 of 125 individuals intentionally ingesting large doses of copper sulfate (Ahasan et al. Hematuria, glycosuria, cylindruria, and proteinuria, indicative of renal tubular damage, were observed in a child who drank a solution containing approximately 3 g of copper sulfate (Walsh et al. A number of animal studies confirm that the kidney is a target of copper toxicity. Renal toxicity as a result of copper loading follows a specific time course (Haywood 1980, 1985; Haywood et al. However, eosinophilic droplets were observed in the epithelial cell cytoplasm of the proximal convoluted tubules in rats exposed to 450 mg Cu/kg/day for 2 weeks (Haywood et al. The number of eosinophilic droplets increased with increasing duration (Haywood 1980, 1985).

Since humans are completely unaware of excessive blood pressure, it is only through measurements that it becomes detected. The exception is malignant hypertension, which can cause headache, congestive heart failure, stroke, seizure, papilledema, renal failure and anuria. Long-standing hypertension causes accelerated atherosclerosis, which in turns leads to all of the biological fallout of this disease. Some consequences include: stroke, coronary artery disease, myocardial infarction, aneurysmal and occlusive aortic disease. Long-standing hypertension can also cause the heart to dilate and lose its ability to pump during systole (systolic congestive heart failure). Lastly, the kidneys are injured by long-standing hypertension and this is a significant cause of renal failure in the U. This also called Emax or Es which stand for maximal elastance or elastance at end-systole, respectively. Ea is primarily determined by arterial resistance but arterial compliance effects it too. In essence, the volume lost by one chamber is exactly equal to the volume gained by the other. A hyperdynamic circulation is thought to play a role in the hypertension seen in some young, otherwise fit African-American males. The very full heart would then eject a large volume into the arterial tree thus leading to hypertension. The high intravascular volume could be caused by renal dysfunction with subsequent fluid retention, or it could be due to exogenous administration. There does seem to be a subset of patients that has an elevated intravascular volume Nevertheless, the excessive intravascular volume mechanism appears to occur infrequently since many newly diagnosed hypertensive patients actually have a contracted intravascular volume. The excessive intravascular volume mechanism also implies that the cardiac output would be elevated, but it is usually normal. Excess venous return could also occur even with a reduced intravascular volume if the venous tone were significantly elevated. This can occur either because the resistance is too high or because the compliance is too low. Furthermore, in older humans, the arterial tree becomes stiffer and less compliant. Thus, for a given stroke volume delivered into the arterial tree, the pressure goes up, especially the systolic pressure. Rational pharmacotherapy of hypertension is based on the four mechanisms outlined above. Reduce venous tone and thus venous return: Central sympatholytics such as clonidine act to reduce overall sympathetic tone. Their initial effects are said to be mediated by decreasing intravascular volume, however (as mentioned above) most untreated hypertensives have contracted intravascular volume. Diuretics cause peripheral vascular resistance to fall through an unknown mechanism. Unfortunately thiazide diuretics have a number of undesirable metabolic effects such as hypercalcemia, hypokalemia, hyponatremia, hyperglycemia, hyperlipidemia, and hyperuricemia. When thiazide diuretics are used in low doses, their side effects seem to be minimized. They cause a very brisk diuresis, but their anti-hypertensive effects are actually not that strong. Acute intravenous administration of furosemide can cause venodilation by an unknown mechanism. Loop diuretics are often part of treatment for malignant hypertension and hypertension with hypervolemia. The metabolic derangements produced by these drugs (particularly hypokalemia, and hypocalcemia) can be profound. Amiloride and triamterene inhibit the Na/proton exchanger in the distal and collecting tubules. Spironolactone inhibits the Na/K exchanger affected by aldosterone, and it is particularly effective in the face of hyperaldosteronism. Sympatholytics (beta-blockers, mixed alpha and beta-blockers, alpha-blockers and central sympatholytics). These drugs are also useful for men who have benign prostatic hypertrophy because they can reduce bladder outlet obstruction. Unlike the beta blockers and thiazide diuretics, the alpha blockers have not been shown to decrease mortality. Thus, the indications for these drugs in hypertension are currently unclear, and they are not considered first line treatments. Non-selective alpha blockers such as phenoxybenzamine and phentolamine are not used for hypertension because they produce an excessive amount of reflex tachycardia. However, the profound alpha blockade possible with the non-competitive antagonist, phenoxybenzamine, has proven very useful in the treatment of pheochromocytoma.
