Noctiva: A New Treatment for Annoying Nighttime Peeing

June 23, 2018

bottles-8MM[1]There is compelling medical evidence that a good night’s sleep is of vital importance for one’s health. We recognize this intuitively when we compare how we feel after a night of sleeping well as opposed to a night of sleep deprivation, but it goes way beyond mere fatigue.  Sleeping well is a key component to cognitive and physical fitness as well as overall health, equally important to diet and exercise. Aside from daytime fatigue, weight gain because of altered eating patterns, and increased risk of traffic accidents and fall-related nighttime injuries, sleep deprivation has been associated with an assortment of medical problems that negatively affect quality and quantity of life.  

Although there are many reasons for failing to obtain sufficient sleep, one such cause is interrupted sleep from the need to frequently empty one’s bladder. This can be disruptive to achieving a good night’s sleep, with many nighttime voiders unable to get back to sleep after urinating. Today’s entry reviews a new medication that can help sleep-disruptive nighttime urinating when it is caused by overproduction of urine, a causal factor in over 80% of cases of nighttime urination.

Nighttime urination—nocturia in medical speak—is a complex condition that aside from affecting quality of sleep and quality of life can be a symptom of underlying medical issues, e.g., diabetes, obstructive sleep apnea and cardiovascular issues. It is common in both women and men, tends to increase with aging, and its underlying basis is often multifactorial.  If it occurs once or twice a night and is not too bothersome and one can readily get back to sleep, it is no big deal.  However, if it occurs more than twice a night and is sleep-disruptive, it may be time to consider a means of improving the situation. Importantly, although nocturia is typically a complaint that drives patients to urologists, most of the time the nocturia is NOT urological in origin.

A simple test to help assess nocturia is a 24-hour voiding diary, which requires a pen and paper, a watch or clock and a measuring cup. The time at which urination occurs and the volume of each urination are recorded. Typical bladder capacity is 10–12 ounces with 4–6 urinations per 24 hours. Such a diary will help differentiate between those with a reduced bladder capacity, those who produce lots of urine only while sleeping, and those who produce lots of urine both day and night.

Reduced bladder capacity is often a sign of urological issues including overactive bladder, benign prostate enlargement, neurological diseases affecting the bladder, and loss of elasticity of the bladder as may occur with pelvic radiation.

Those who produce lots of urine only while sleeping are commonly found to have the following causes: increased fluid intake in the evening, obstructive sleep apnea, edematous states such as congestive heart failure, and failure to produce sufficient quantity of a hormone that regulates urine production.

Drinking a few cups of coffee or tea after dinner or a few beers before bedtime will cause nighttime urination and has an obvious solution. Obstructive sleep apnea is a under-appreciated and common cause of full-volume nighttime urination that when treated with CPAP (continuous positive airway pressure) or other means will significantly reduce the nocturia. Edema is fluid within the tissues–-typically the ankles and legs–that tends to accumulate aided by gravity over the course of the day. Upon assuming the lying-down position when sleeping, the legs are relatively elevated as opposed to standing and this tissue fluid returns into circulation, causing the kidneys to increase urine production. In general, those with peripheral edema go to sleep with ankles and legs engorged with edema fluid and wake up with thinner legs, as the return of some of the fluid to the circulation and the subsequent increased urination rids them of this. Another possibility is an abnormality in the nocturnal secretion of anti-diuretic hormoneThis pituitary hormone causes the kidneys to concentrate urine and pull water back into the circulation; nocturia may occur because of an age associated decline in its secretion while sleeping.

Those who produce lots of urine both day and night often have overzealous fluid intake, diabetes mellitus or diabetes insipidus, or are on certain medications (e.g., lithium) that can cause the problem.

Noctiva (Desmopressin) to treat nocturnal excessive urine production

One of the most common reasons for nocturia is excessive nighttime urine production, defined as nighttime urine volume exceeding 1/3 of the 24-hour urine production.  If this is demonstrated on the voiding diary, you may be a candidate for this anti-diuretic medication that works by decreasing nocturnal urinary production.

Desmopressin is a synthetic version of anti-diuretic hormone. The function of this hormone is to put the “brakes” on the kidneys so that the kidneys do not allow excessive loss of body water, which could be detrimental to one’s health and lead to severe dehydration. For years, desmopressin has been used for children who are bed wetters.

Noctiva (Desmopressin) nasal spray is a new formulation of intranasal desmopressin for those who have full-bladder volume nocturia two or more times.  It is a modification of desmopressin that is designed to enhance absorption from the nasal lining, available in doses of 0.83 and 1.66 microgram.  One spray in either nostril is used about 30 minutes prior to sleep.

The absorption of this product is enhanced as compared to that of the oral version (8% vs. 0.3%), which means more consistent dosing and rapid absorption and elimination allowing more rapid onset and less prolonged drug activity.  It is well tolerated with the most common side effect low levels of sodium and other side effects including nasal irritation, nasal congestion, nosebleeds, sneezing, and high blood pressure.  The drug cannot be used in the face of excessive fluid intake, low serum sodium, steroids or loop diuretic use, heart failure, uncontrolled high blood pressure, poor kidney function, and with illnesses causing fluid and electrolyte imbalances. Sodium levels need to be monitored periodically.

Bottom Line: Nocturnal urinary frequency should be investigated to determine its cause, which may in fact be related to conditions other than urinary tract issues.  Nighttime urination is not only bothersome but may also pose real health risks as chronically disturbed sleep can lead to a host of collateral wellness issues. Noctiva is a new addition to the armamentarium to combat nighttime urination when it is due to excessive nocturnal urinary production.

Wishing you the best of health,

Getting Up At Night Gets Me Down: Nighttime Urinating

May 24, 2014

Blog #155

Getting up once to relieve your bladder during sleep hours is usually not particularly troublesome. However, when it happens two or more times, it can negatively impact one’s quality of life because of sleep disruption, daytime fatigue, an increased risk of fatigue-related accidents and an increased risk of fall-related nighttime injuries. Fatigue has a negative effect on just about everything, even influencing us to mindlessly eat.

Nocturia is the medical term for the need to awaken from sleep to urinate. One’s natural response is to think urinary bladder problem and seek a consultation with a urologist, the type of doctor who specializes in the urinary system. Although nocturia manifests itself via the bladder and much of the time is a urological issue, it is often not a bladderproblem. Rather, the kidneys are frequently culprits in contributing to the condition.

The kidneys are remarkable organs that can multitask like no other. They not only filter blood to remove waste products, but are also responsible for other vital body functions: They are in charge of maintaining the proper fluid volume within our blood stream. They regulate the levels of our electrolytes including sodium, potassium, chloride, etc. They keep our blood pH (indicator of acidity) at a precise level to maintain optimal function. They are key players in the regulation of blood pressure. Furthermore—and unbeknownst to many—they are responsible for the production of several important hormones: calcitrol (calcium regulation), erythropoietin (red blood cell production), and renin (blood pressure regulation). The kidneys regulate our blood volume by concentrating or diluting our urine depending on our state of hydration. When we are over-hydrated, the kidneys dilute the urine to rid our bodies of excess fluid, resulting in virtually clear urine. When we are dehydrated, the kidneys concentrate urine to preserve our fluid volume, resulting in very concentrated urine that can look as dark as apple cider.

Nocturia correlates with aging and the associated decline in kidney function and decreased ability to concentrate urine. Although having an enlarged prostate may certainly contribute to nocturia, it is obviously much more complicated than this since women do not have prostates and nocturia is equally prevalent in men and women. As simple as getting up at night to urinate sounds, it is actually a complex condition often based upon multiple factors that require careful evaluation in order to sort out and treat appropriately. When a urology consultation is sought, our goal is to distinguish between urological and non-urological causes for nighttime urinating. It often comes down to one of three factors: nighttime urine production by the kidneys; capacity of the urinary bladder; and sleep status. In the elderly population, excessive nighttime urine production is a factor almost 90% of the time.

Nocturia can ultimately be classified into one or more of 5 categories: global polyuria (making too much urine, day and night); nocturnal polyuria (making too much urine at night); reduced bladder capacity; sleep disorders; and circadian clock disorders (problems with our bio-rhythms). Global polyuria can result from excessive fluid intake from overenthusiastic drinking or from dehydration from poorly controlled diabetes mellitus (sugar diabetes). The pituitary gland within our brain manufactures an important hormone responsible for water regulation. This hormone is ADH—anti-diuretic hormone—and it works by giving the message to the kidneys to concentrate urine. Diabetes insipidus is a disease of either kidney origin—in which the kidneys do not respond to ADH—or pituitary origin—in which there is deficient secretion of ADH. In either case, lots of urine will be made, resulting in frequent urination, both daytime and nighttime. Medications including diuretics, SSRIs (selective serotonin reuptake inhibitors), calcium blockers, tetracycline and lithium may induce global polyuria.

Nocturnal polyuria may be on the basis of excessive fluid intake, especially diuretic beverages including caffeine and alcohol, a nocturnal defect in the secretion of ADH, and unresponsiveness of the kidneys to the action of ADH. Congestive heart failure, sleep apnea and kidney insufficiency may also play a role. Certain conditions result in accumulation of fluids in tissues of the body such as the legs (peripheral edema); when lying down to sleep, the fluid is no longer under the same pressures as determined by gravity, and returns to the intravascular (within the blood vessels) compartment. It is then subject to being released from the kidneys as urine. Such conditions include heart, kidney and liver impairment, nephrotic syndrome, malnutrition and venous stasis. Circadian clock disorders cause reduced ADH secretion or activity, resulting in dilute urine that causes nocturia.

Nocturia may also be caused by primary sleep disorders including insomnia, restless leg syndrome, narcolepsy, and arousal disorders (sleepwalking, nightmares, etc.)

There are numerous urological causes of reduced bladder capacity. Any abnormal process that occurs within the bladder can irritate its delicate lining, causing a reduced capacity: bladder infections, bladder stones, bladder cancer, bacterial cystitits, radiation cystitis, and interstitial cystitis. An overactive bladder—a bladder that “squeezes without its owner’s permission”—can cause nocturia. Some people have small bladder capacities on the basis of scarring, radiation, or other forms of damage. Prostate enlargement commonly gives rise to nocturia, as can many neurological diseases that often have profound effects on bladder function. Incomplete bladder emptying can give rise to frequent urination since the bladder is already starting out on a bias of being partially filled. This problem can occur with prostate enlargement, scar tissue in the urethra, neurologic issues, and bladder prolapse.

The principal diagnostic tool for nocturia is the frequency-volume chart (FVC), a simple test that can effectively guide diagnosis and treatment. This is a 24-hour record of the time of urination and volume of urination, requiring a clock, pencil, paper and measuring cup. Typical bladder capacity is 10–12 ounces with 4–6 urinations per day. Reduced bladder capacity is a condition in which frequent urination occurs with low bladder capacities, for example, 3–4 ounces per void. Global polyuria is a condition in which bladder volumes are full and appropriate and the frequency occurs both daytime and nighttime. Nocturnal polyuria is nocturnal urinary frequency with full and appropriate volumes, with daytime voiding patterns being normal.

Lifestyle modifications to improve nocturia include the following: preemptive voiding before bedtime, intentional nocturnal and late afternoon dehydration, salt restriction, dietary restriction of caffeine and alcohol, adjustment of medication timing, use of compression stockings with afternoon and evening leg elevation, and use of sleep medications as necessary.

Urological issues may need to be managed with medications that relax or shrink the prostate when the issue is prostate obstruction, and bladder relaxants for overactive bladder. For nocturnal polyuria, synthetic ADH (an orally disintegrating sublingual tablet) in dosages of 50-100 micrograms for men and 25 micrograms for women can be highly effective.

Bottom Line: Nocturia should be investigated to determine its cause, which may often in fact be related to conditions other than urinary tract issues. Nighttime urination is not only bothersome, but may also pose real health risks. Chronically disturbed sleep can lead to a host of collateral wellness issues.
