مسدودسازی گیرندههای ۶ سروتونین مرکزی سبب افزایش پیامرسانیکولینرژیک و گلوتامینرژیک در نواحی مختلف مغز میشود؛[۱۰][۱۱][۱۲][۱۳] حال آنکه تحریک این گیرندهها سبب افزایش سیگنالینگ گابائرژیک گسترده میگردد.[۱۴]
بهنظر میرسد که آنتاگونیستهای گیرنده ۶ سروتونین ممکن است در بهبود شناخت، یادگیری و حافظه نقش داشته باشند.[۱۶] در نتیجه در سالهای اخیر، پژوهشگران سعی در ساخت داروهای آنتاگونیست خاصی برای این گیرنده جهت درمان بیماری آلزایمر و سایر انواع زوال عقل نمودهاند.[۱۳][۱۷][۱۸] هرچند نتایج آنها چندان امیدوارکننده نبوده است.
آنتاگونیستهای این گیرنده همچنین سبب کاهش اشتها و کاهش وزن میگردند و داروهای آزمایشی خاصی برای درمان احتمالی چاقی تولید و در دست پژوهش است.[۱۹][۲۰]
