Praziquantel is one of the most important drugs in tropical medicine &mdash; the global standard for schistosomiasis (which affects roughly 240 million people worldwide), and the agent of choice for most cestode and trematode infections. WHO mass-drug-administration programmes have used praziquantel to treat over a billion people since the 1990s.<\/p>\n<h2 class=\"wp-block-heading\">Mechanismus \u00fa\u010dinku<\/h2>\n<p>Praziquantel <strong>increases calcium permeability<\/strong> across the parasite tegument (outer covering), causing rapid sustained muscle contraction. This paralyses the worm and exposes its surface antigens to host immune attack &mdash; a one-two punch of pharmacological paralysis followed by immune-mediated killing. The mechanism explains why praziquantel works so well in immunocompetent patients and is somewhat less effective in heavily immunosuppressed hosts.<\/p>\n<p>Oral bioavailability is good (~80%) but first-pass hepatic metabolism is heavy &mdash; only about 25% reaches systemic circulation as active drug. Plasma half-life is 1&ndash;1.5 hours.<\/p>\n<h2 class=\"wp-block-heading\">Prazinec indications and dose<\/h2>\n<table style=\"width:100%;border-collapse:collapse;margin:14px 0;font-size:14px;\">\n<thead>\n<tr style=\"background:#2c7cb0;color:#fff;\">\n<th style=\"padding:8px;text-align:left;border:1px solid #ddd;\">Indikace<\/th>\n<th style=\"padding:8px;text-align:left;border:1px solid #ddd;\">D\u00e1vka<\/th>\n<th style=\"padding:8px;text-align:left;border:1px solid #ddd;\">D\u00e1vkovac\u00ed sch\u00e9ma<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding:8px;border:1px solid #ddd;\">Schistosomiasis (S. mansoni, S. haematobium, S. japonicum)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">40&nbsp;mg\/kg<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Single dose (S. japonicum: 60&nbsp;mg\/kg)<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Intestinal tapeworm (Taenia saginata, T. solium)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">5&ndash;10&nbsp;mg\/kg<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Jednor\u00e1zov\u00e1 d\u00e1vka<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:8px;border:1px solid #ddd;\">(trpasli\u010d\u00ed tasemnice),<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">25&nbsp;mg\/kg<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Single dose, repeat at 1 week<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Liver flukes (Clonorchis, Opisthorchis)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">25&nbsp;mg\/kg TID<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">For 1 day (75&nbsp;mg\/kg total)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:8px;border:1px solid #ddd;\">Lung fluke (Paragonimus)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">25&nbsp;mg\/kg TID<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">For 2 days<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Neurocysticercosis (specialist)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">50&nbsp;mg\/kg\/day in 3 doses<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">For 14&ndash;30 days WITH steroid cover<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Take with water or a soft drink during or shortly after a meal.

Egg shedding stops over the following 1&ndash;2 weeks. For schistosomiasis, urine or stool testing at 4&ndash;6 weeks confirms cure.<\/p>\n<h3 class=\"wp-block-heading\">Why take Prazinec with food?<\/h3>\n<p>Food increases bioavailability roughly 2-fold. For most indications this is helpful. Do not chew &mdash; the bitter taste is intense.<\/p>\n<h3 class=\"wp-block-heading\">Will I see worms in my stool after?<\/h3>\n<p>For tapeworm, expect partial passage of fragmented proglottids over the days following the dose &mdash; the worm is partly digested by host enzymes after praziquantel has done its job. For schistosomiasis the eggs are microscopic; you won&rsquo;t see worms.<\/p>\n<h3 class=\"wp-block-heading\">Is Prazinec safe in pregnancy?<\/h3>\n<p>WHO endorses praziquantel use in pregnancy where infection is symptomatic or the worm burden is significant. The first trimester is preferred to be avoided where alternatives exist. Consult a clinician for individualised guidance.<\/p>\n<h3 class=\"wp-block-heading\">Can children take Prazinec?<\/h3>\n<p>Yes from age 4 with the same weight-based dosing as adults. WHO mass-drug-administration programmes routinely treat school-age children for schistosomiasis with single-dose praziquantel.<\/p>\n<h3 class=\"wp-block-heading\">What if I have neurocysticercosis?<\/h3>\n<p>Treatment requires neurology supervision. MRI imaging, concurrent dexamethasone, and (for ocular involvement) ophthalmology assessment are mandatory. Self-treatment can be catastrophic &mdash; the brain inflammation from dying cysts can cause raised intracranial pressure.<\/p>\n<h3 class=\"wp-block-heading\">Does praziquantel treat ascaris or pinworm?<\/h3>\n<p>No. Praziquantel covers cestodes (tapeworms) and trematodes (flukes including schistosoma). For nematodes (ascaris, pinworm, hookworm, whipworm) use albendazole or mebendazole.<\/p>\n<h3 class=\"wp-block-heading\">Can I drink alcohol after the dose?<\/h3>\n<p>Avoid alcohol on the day of treatment &mdash; it amplifies the dizziness and drowsiness common in the first 24&nbsp;hours.<\/p>\n<h3 class=\"wp-block-heading\">Why might Prazinec fail?<\/h3>\n<p>Most common reasons: under-dosing (especially in heavy patients), reinfection from continued exposure (re-entering schistosomiasis-endemic water bodies), or co-administration with strong CYP3A4 inducers (rifampicin, anticonvulsants) that reduce drug levels.<\/p>\n<h3 class=\"wp-block-heading\">Should I retest after treatment?<\/h3>\n<p>For schistosomiasis, retest with urine or stool at 4&ndash;6 weeks. For intestinal tapeworm, retest at 1 and 3 months. For neurocysticercosis, repeat MRI at 3&ndash;6 months under specialist guidance.<\/p>\n<p><!-- medsbase-related-alts-v1 --><\/p>\n<h3 class=\"wp-block-heading\">Dal\u0161\u00ed antiparazit\u00e1rn\u00ed l\u00e9ky<\/h3>\n<ul>\n<li><a href=\"https:\/\/medsbase.com\/cs\/niclosig\/\">Niclosig (niclosamide 500 mg)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/cs\/prazinec\/\">Prazinec (praziquantel 600 mg)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/cs\/abd-400-albendazole\/\">ABD 400 (albendazol 400 mg)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/cs\/mebex\/\">Mebex (mebendazole)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/cs\/tinvista\/\">Tinvista (tinidazole)<\/a><\/li>\n<\/ul>\n<div style=\"background:#fff3f3;border-left:4px solid #d9534f;padding:14px 18px;margin:22px 0;border-radius:4px;font-size:14px;color:#444;\"><strong>Zdravotn\u00ed prohl\u00e1\u0161en\u00ed.<\/strong> Tato str\u00e1nka slou\u017e\u00ed pouze pro vzd\u011bl\u00e1vac\u00ed \u00fa\u010dely a nenahrazuje odborn\u00e9 l\u00e9ka\u0159sk\u00e9 poradenstv\u00ed.
