When trazodone overdoses occur, clinicians should carefully monitor for low blood pressure, a potentially serious toxic effect. In a report of a fatal trazodone overdose, torsades de pointes and complete atrioventricular block developed, along with subsequent multiple organ failure, with a trazodone plasma concentration of 25.4 mg/L on admission.
Severe symptoms include severe increases in heart rate and blood pressure. Temperature may rise to above 41.1 °C (106.0 °F) in life-threatening cases. Other abnormalities include metabolic acidosis, rhabdomyolysis, seizures, kidney failure, and disseminated intravascular coagulation; these effects usually arising as a consequence of hyperthermia.
This is a list of adverse effects of the antidepressant trazodone, sorted by frequency of occurrence. [1] [2] [3] Very common.
Antabuse – inhibits the enzyme acetaldehyde dehydrogenase, causing acetaldehyde poisoning when ethanol is consumed; used to cause severe hangover when drinking; increases liver, kidney, and brain damage from drinking
Volume of blood plasma delivered to the kidney per unit time. PAH clearance is a renal analysis method used to provide an estimate. Approximately 625 ml/min. renal blood flow = (HCT is hematocrit) Volume of blood delivered to the kidney per unit time. In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...
Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that a reduction of blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%.
However, the kidneys must continue to filter enough blood despite this drop in blood flow, necessitating mechanisms to keep glomerular blood pressure up. To do this, angiotensin II constricts efferent arterioles, which forces blood to build up in the glomerulus, increasing glomerular pressure. The glomerular filtration rate (GFR) is thus ...
The adrenergic antagonists are widely used for lowering blood pressure and relieving hypertension. [16] These antagonists have a been proven to relieve the pain caused by myocardial infarction, and also the infarction size, which correlates with heart rate. [17] There are few non-cardiovascular uses for adrenergic antagonists.
