Available strengths: <strong>2 mg<\/strong>. Pimozide is a butyrophenone (related to haloperidol) with selective D2 antagonism, modest 5-HT2A antagonism, and meaningful calcium-channel blockade \u2014 the latter is the basis for the QT-prolonging effect that limits its use.<\/p>\n<p>Modern indications: refractory Tourette syndrome (FDA approval), monosymptomatic delusional disorder (e.g. delusions of parasitosis, somatic delusions), and rare schizophrenia cases unresponsive to other agents.<\/p>\n<h2>Indicaties en dosering<\/h2>\n<table>\n<thead>\n<tr>\n<th>Indicatie<\/th>\n<th>Startdosering<\/th>\n<th>Streefdosering<\/th>\n<th>Maximaal<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Tourette syndrome (adult)<\/td>\n<td>1 mg HS<\/td>\n<td>1\u201310 mg\/day<\/td>\n<td>0.2 mg\/kg or 10 mg<\/td>\n<\/tr>\n<tr>\n<td>Tourette syndrome (paediatric \u2265 12 y)<\/td>\n<td>0.05 mg\/kg HS<\/td>\n<td>0.2 mg\/kg\/day<\/td>\n<td>0.2 mg\/kg or 10 mg<\/td>\n<\/tr>\n<tr>\n<td>Monosymptomatic delusional disorder<\/td>\n<td>2 mg eenmaal daags<\/td>\n<td>2\u20134 mg\/dag<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<tr>\n<td>Schizophrenia (refractory)<\/td>\n<td>1 mg BID<\/td>\n<td>2\u201310 mg\/day<\/td>\n<td>20 mg<\/td>\n<\/tr>\n<tr>\n<td>CYP2D6 poor metaboliser \/ inhibitor<\/td>\n<td>halveer de dosis<\/td>\n<td>\u2014<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Belangrijke veiligheidsoverwegingen<\/h2>\n<div style=\"background:#fff3f3;border-left:4px solid #d9534f;padding:14px 18px;margin:18px 0;border-radius:4px;\">\n<strong>FDA black-box \u2014 dementiegerelateerde psychose<\/strong><\/p>\n<p style=\"margin-bottom:0;\">Alle atypische antipsychotica dragen een FDA black-box waarschuwing voor verhoogde sterfte (voornamelijk cardiovasculair en infectieus) bij gebruik voor gedragsstoornissen bij oudere volwassenen met dementie. <strong>Atypische antipsychotica zijn niet goedgekeurd voor dementiegerelateerde psychose of agitatie.<\/strong>.

Its modern niche is therefore narrow \u2014 refractory Tourette syndrome and monosymptomatic delusional disorder where other agents have failed.<\/p>\n<h3>Why is Mozep useful for delusional parasitosis?<\/h3>\n<p>Monosymptomatic delusional disorder (delusions of parasitosis, somatic delusions, delusions of body odour) responded particularly well to pimozide in older case series \u2014 possibly because of the strong selective D2 blockade. Modern practice often prefers a low-dose atypical (risperidone, olanzapine) but pimozide retains a niche where atypicals have failed.<\/p>\n<h3>Why pre-treatment ECG?<\/h3>\n<p>Pimozide&rsquo;s QT prolongation is the dose-limiting toxicity. A baseline ECG defines the patient&rsquo;s starting QTc; the prescriber checks QTc at every dose increase. Stop or dose-reduce if QTc &gt; 500 ms or rises &gt; 60 ms from baseline. This is non-negotiable.<\/p>\n<h3>Waarom grapefruitsap vermijden?<\/h3>\n<p>Grapefruit juice strongly inhibits intestinal CYP3A4 \u2014 pimozide levels rise several-fold, amplifying the QT signal into the dangerous range. Grapefruit and grapefruit juice are absolute contraindications during pimozide therapy.<\/p>\n<h3>Can Mozep be combined with an SSRI?<\/h3>\n<p>Most SSRIs are absolute or relative contraindications because of CYP2D6 inhibition (paroxetine, fluoxetine, bupropion). Sertraline and escitalopram are the safer SSRIs if combination is necessary, but ECG monitoring is still required.<\/p>\n<h3>How long until Mozep works?<\/h3>\n<p>Tic reduction often visible within 1\u20132 weeks of titration. Full effect at 4\u20136 weeks. Delusional disorder: 4\u20138 weeks.<\/p>\n<h3>Can Mozep be stopped abruptly?<\/h3>\n<p>Taper over 2\u20134 weeks. Cholinergic rebound and tic rebound (in Tourette) can be problematic on abrupt cessation.<\/p>\n<h3>Will Mozep cause weight gain?<\/h3>\n<p>Modest \u2014 typically 1\u20133 kg over 6 months.<\/p>\n<h3>What about driving on Mozep?<\/h3>\n<p>Sedation is moderate. Most patients on stable doses drive normally; first 1\u20132 weeks of titration can impair reaction time.<\/p>\n<h3>Are there alternatives to Mozep for Tourette?<\/h3>\n<p>Yes \u2014 aripiprazole, risperidone, and clonidine\/guanfacine are commonly used. Most patients respond to one of these without needing pimozide. Pimozide is reserved for refractory cases.<\/p>\n<h2>Andere medicijnen voor geestelijke gezondheid<\/h2>\n<ul>\n<li><a href=\"https:\/\/medsbase.com\/nl\/aripicon\/\">Aripicon (Aripiprazole \u2014 atypisch, lage EPS)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/risdone\/\">Risdone (Risperidon)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/olanzap\/\">Olanzap (Olanzapine)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/sulpitac\/\">Sulpitac (Amisulpride)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/skizoril\/\">Skizoril (Clozapine \u2014 refractaire aandoening)<\/a><\/li>\n<\/ul>\n<p><!-- medsbase-related-alts-v1 --><\/p>\n<div style=\"background:#fff3f3;border-left:4px solid #d9534f;padding:14px 18px;margin:18px 0;border-radius:4px;font-size:0.9em;\">\n<strong>Medisch disclaimer.<\/strong> Deze pagina is educatief en geen vervanging voor persoonlijk medisch advies.
