Restoril: Temazepam bindet an die Benzodiazepin-Bindungsstelle des GABA-A-Rezeptors und verstärkt allosterisch die hemmende Chloridleitfähigkeit. Synthroid: Levothyroxin ersetzt das defizitäre endogene Thyroxin, das in den Geweben durch Deiodinasen in das aktive Hormon Trijodthyronin (T3) umgewandelt wird.
When Restoril is preferred
