5 Pharmacotherapie: anticholinergica bij de geriatrische patiënt
Constipatie fecale impactie Wazig zicht Droge monde carries Cognitieve achteruitgang Aggressie Nevenwerkingen meer frequent, bij lagere dosis, meer uitgesproken en met grotere impact The higher frequency and greater severity of adverse events in this population, even at lower treatment doses, also should carefully be considered when choosing pharmacotherapy The specific considerations that need to be addressed in the elderly are constipation and fecal impaction, particularly in bedridden patients blurred vision, which can lead to falls and other problems social isolation and cognitive impairment, which can lead to acute confusion and could possibly be misdiagnosed as dementia effects on the salivary gland that can cause dry mouth leading to tooth decay Lamy PP.

6 Anticholinergica en potentieel cognitieve achteruitgang
Acetylcholine is belangrijke mediator voor korte termijn geheugen Ook andere medicatie kan cognitieve achteruitgang veroorzaken (antihistaminica, antispasmodica, anti-psychotica) Dubbel blind, placebo gecontroleerde crossover studie: placebo, oxybutynine 5 mg en 10 mg (n = 12 gezonde vrijwilligers, leeftijd 65–76) Pleidooi voor tolterodine, solifenacin Drachman DA, et al. Neurobiol Aging. 1980;1:39-43. Katz IR, et al. J Am Geriatr Soc.1998;46:8-13.

7 Urinaire anticholinergica en cardiaal risico bij patiënten met OAB
Retrospectieve cohort analyse patiënten met urge incontinentie 65 jaar: mediane leeftijd ~ 79j Resultaten: geen associatie tussen gebruik urinaire anticholinergica en verhoogd risico op ventriculaire arrythmie of plotse dood Wang PS et al. J Am Geriatr Soc. 2002;50:

The non receptor selectivity of tolterodine are clear from these data. Lager cijfer = hogere receptor selectiviteit *fase 3 studies veelbelovend *Adapted from Gillberg et al., 1998; Nilvebrant et al., 1997.

11 Receptor/orgaan Selectiviteit van anticholinergica
Solufenacin (Vesicare): M 2-3 selectiviteit (x 2 vs oxy, x 4 vs tolter, << darif) blaas versus speekselklieren (3 x hoger vs alle andere) selectiviteit bij dier en mens (phase 2-3) - Bij dieren geen centrale symptomen tot 3 mg/kg This slide compares receptor selectivity for tolterodine, oxybutynin, and darifenacin, with lower numbers indicating higher selectivity. The non receptor selectivity of tolterodine are clear from these data.

12 Oxybutinine TDS Darifenacine Trospium chloride
Kentera (UCB) Minder bijwerkingen door minder N-deoxymetabolieten Klinische studies minder spectaculair Sinds kort op de markt in België Darifenacine Emselex (Novartis), uitgesproken receptorspecifiek Trospium chloride Regurin (Madaus), orgaanspecifiek, goedkoop!!!!

13 Biologische neuromodulatie
Vanilloieden: Capsaicine, Resiniferatoxine (RTX) Via vanilloied receptoren op C-vezels neurogene OAB en Blaaspijn blokkeren, werkt niet voor idiopatische OAB. Via vanilloied recepto Conotoxine (uit slakken) Blokkeert nicotine receptoren = sfincter paralyse Botuline toxine: Botox, Disport Blokkeert niet enkel Ac Col maar ook norepinephrine, ATP, sub P, CGRP, ATP, NO, glutamaat release Vandaar effect bij idiop OAB, hyperreflexie en IC RPS Everaert K.

26 NOCTURIE – desmopressine meta-analyse
Bewezen vermindering nocturie, nachtelijke polyurie en verbetering QOL Risico hyponatriëmie: 7.6% (3-20%) - korte follow-up! - cardiale, renale co-morbiditeit exclusie - geen andere medicatie die hyponatriëmie kan veroorzaken Voorzichtigheid en monitoring aangewezen monitoring!!: bloedanalyse dag 3 en 7 Minirin (1-4 puffs bij slapengaan), Desmopressine Ferring (1-2 pillen 1 uur voor slapengaan) The elderly adult takes an average of 5 medications (not including vitamins) One study found that 10 of the top 25 prescribed drugs in the elderly had some anticholinergic properties Possible drug effects to consider are those that may cause symptoms that mimic those of OAB, from medications including diuretics and the antihypertensives. Treatment schedules can be manipulated to minimize possible complications between OAB therapies and these medications that also effect filling and voiding Other considerations include: effects from the acetylcholinesterase inhibitors, that primarily act on M1 receptors within the brain, but their effects on the micturition axis are unknown. anticholinergic adverse effects of medications, eg, the antidepressants, antihistamines, antipsychotics, and over‑the‑counter sleep aids like Tylenol PM® (acetaminophen and diphenhydramine). These effects may be augmented by the addition of an antimuscarinic agent. Thus, regimen’s must be scrutinized for potential interactions. Weatherall M. J Neurourol Urodyn 2004;23:
