5.Pharmacological properties

Pharmacotherapeuticgroup: Anthelminthics

ATCvet code: QP54AA51

5.1 Pharmacodynamicproperties

Ivermectin is a macrocyclic-lactone derivativewhich has a broad antiparasitic activityagainst

nematodes andarthropods.It acts byinhibitingnerveimpulses.Its modeofaction includes the

glutamate-gatedchlorideion channels.Ivermectinbindsselectivelyand with high affinityto

glutamate-gatedchlorideion channels which occurin invertebrate nerveandmusclecells. This

leads to an increasein thepermeabilityof thecellmembraneto chlorideionswith

hyperpolarization ofthenerveor musclecell,resultingin paralysisand death of the relevant

parasites. Compoundsofthis class mayalso interact with otherligand-gated chloridechannels,

suchas thosegated bytheneurotransmitter gamma-aminobutyric acid (GABA). Themargin of

safetyforcompoundsofthis class is attributableto thefact that mammalsdo not have

glutamate-gatedchloridechannels.Praziquantel is a pyrazinoisoquinolinederivativewhich

exerts its anthelmintic activityagainstmanyspecies of cestodesand trematodes.It primarily

actsbyimpairingboth motilityandfunction ofthesuckers ofcestodes.Itsmode ofaction

includes the impairingofneuromuscularco-ordination but also influencing thepermeabilityof

the integument oftheworms, which leads to excessivecalcium andglucoseloss. This induces

spastic paralysisof theparasitemusculature.

5.2 Pharmacokineticparticulars

Afteradministration oftherecommended dosageto horses, the ivermectin plasma peak was

reached within 24 hours.Theivermectin concentration was still over2 ng/ml 14 daysafter

administration. Theelimination half-lifeof ivermectin was 90h. With regard to praziquantel,

the plasma peak was reached within 1 hour. Thepraziquantel was rapidlyeliminated and was

not detected after 8 hpost treatment. Theelimination half-lifeof praziquantel was 40 min.

Blokhuis: maatregelen nodig tegen probleemgebruik energiedrankjes

Een relatief kleine groep jongeren tussen de 13 en 18 jaar drinkt te veel energiedrank en loopt daarmee risico op gezondheidsklachten. Dat blijkt uit onderzoek dat het RIVM uitvoerde in opdracht van staatssecretaris Paul Blokhuis (VWS) naar aanleiding van signalen van kinderartsen eerder dit jaar. Over het algemeen is de consumptie van energiedrankjes onder jongeren de afgelopen jaren afgenomen. Vier op de vijf jongeren drinkt het nooit of minder dan wekelijks.
