This study evaluates the extent to which specific drug groups are associated with OH, a common side effect that reduces cerebral blood flow. It finds that beta-blockers, tricyclic antidepressants, alpha-blockers, antipsychotics, and SGLT-2 inhibitors increase the odds of OH, while most vasodilators do not. Orthostatic hypotension is reported as a side effect among people who take Gabapentin (gabapentin), especially for people who are male, 60+ old, have been taking the drug for < 1 month also take Aspirin, and have High blood pressure. Drug-induced orthostatic hypotension is an important clinical problem. When symptomatic, it is poorly tolerated by the patient, and can be a cause for discontinuing treatment. It may have more serious consequences if it leads to syncope, falls and injury, or to sustained loss of perfusion of vital o The depressor effect of gabapentin in the NTS recovered gradually over 90 min after L-NAME treatment (-8 ± 2 versus -20 ± 3 mmHg and -13 ± 3 versus -36 ± 8 bpm; Figure 2B). These results indicated that gabapentin may have induced NOS to induce hypotension and bradycardia in the NTS of the SHR rats. Figure 2. Data on chronic opioid treatment are limited, but hypotension, orthostatic hypotension, and syncope are commonly reported among potential adverse effects of most opioid analgesics, such as morphine, buprenorphine, fentanyl, oxycodone, and tapentadol [55•]. Yet, the mechanism underlying opioid-mediated hypotension still remains a matter of debate. Orthostatic hypotension is a condition described by a significant reduction in blood pressure that typically occurs upon standing or assuming an upright posture. It may be asymptomatic or symptomatic and can be due to impaired autonomic reflexes or intravascular volume depletion. Orthostatic hypotension is a frequent cause of falls and syncope, impairing quality of life. It is an independent risk factor of mortality and a common cause of hospitalizations, which exponentially increases in the geriatric population. We present a management plan based on a systematic literature review and understanding of the underlying pathophysiology and relevant clinical pharmacology Orthostatic hypotension is a chronic, debilitating illness that is difficult to treat. The therapeutic goal is to improve postural symptoms, standing time, and function rather than to achieve upright normotension, which can lead to supine hypertension. Drug therapy alone is never adequate. Orthostatic hypotension tends to be worse early in the morning because of nighttime pressure diuresis with volume depletion (discussed later in this article), and the diagnosis of orthostatic hypotension is hence more readily made in the morning 27. The diagnosis of orthostatic hypotension is easily confirmed at the bedside with orthostatic vitals. Orthostatic hypotension is defined as a decrease in blood pressure of 20 mm Hg or more systolic or 10 mm Hg or more diastolic within three minutes of standing from the supine position or on Chronic orthostatic hypotension (OH) is a common, often underdiagnosed, disorder, defined by an excessive fall in blood pressure (BP) with standing. OH can be associated with postural lightheadedness, dizziness, fatigue, coat hanger pain, and, in extreme situations, syncope, falls, and injuries. In the office, 1 minute of standing probably detects nearly all cases of orthostatic hypotension; however, standing beyond 2 minutes helps establish the severity (a further drop in blood pressure). 4 Orthostatic hypotension developing after 3 minutes of standing is uncommon and may represent a reflex presyncope (eg, vasovagal) or a mild or Hypotension and orthostatic hypotension may contribute to fall risk, but evidence is inconsistent. There is no strong evidence indicating a specific class is preferred over others due to lower fall risk. However, with the possibility of orthostatic hypotension contributing to falls and strong evidence of Several cardiovascular and psychoactive medications may alter the blood pressure response to standing, leading to drug-related orthostatic hypotension. This narrative review provides an overview on cardiovascular and non-cardiovascular medications potentially impairing orthostatic blood pressure. Autonomic complaints are frequently encountered in clinical practice. They can be due to primary autonomic disorders or secondary to other medical conditions. Primary autonomic disorders can be categorized as orthostatic intolerance syndromes and small fiber neuropathies; the latter are associated with autonomic failure, pain, or their combinations. The review outlines orthostatic intolerance Tricyclic antidepressants also cause side-effects that can be troublesome or potentially dangerous, such as anticholinergic effects (dry mouth, blurred vision, urinary retention, ileus), sedation, orthostatic hypotension, tachycardia and atrio-ventricular conduction disturbances. Drug-induced orthostatic hypotension (OH) is common, and its resulting cerebral hypoperfusion is linked to adverse outcomes including falls, strokes, cognitive impairment, and increased mortality. The extent to which specific medications are associated with OH remains unclear. In this pilot study, the investigator will test the usefulness of gabapentin in treating some of the symptoms associated with POTS. Gabapentin is FDA-approved to treat epilepsy and nerve pain and works by reducing excessive activity in the nervous system. Orthostatic hypotension (OH), defined as a reduction in systolic blood pressure (BP) of 20 mm Hg or diastolic BP of 10 mm Hg within 3 minutes of assuming an erect posture [1], is estimated to affect 30% to 70% of older adults [2] and is commonly associated with use of med-ications [3]. The overall rate is approximately 36 per 100,000 US adults and increases exponentially with age. 1 In patients older than the age of 75 years, the annual hospitalization rate related to orthostatic hypotension increases to 233 per 100,000 patients. 2 The prevalence of orthostatic hypotension in institutionalized patients ranges between 30% and
