None (2) · Selective inverse agonist at 5HT2A receptors with weaker activity at 5HT2C. Has no significant dopamine D2 affinity, unique among approved antipsychotics. Inverse agonism (rather than antagonism) reduces constitutive 5HT2A receptor activity below baseline. (1) · '"`UNIQ--vote-00000053-QINU`"' Also raises bradykinin, contributing to vasodilation and the characteristic dry cough. Renally cleared, unmetabolized; dose-adjust by eGFR'"`UNIQ--ref-00000054-QINU`"'. (1) · '"`UNIQ--vote-00000391-QINU`"' Minimal CYP metabolism; mostly renally cleared unchanged.

(1) · '"`UNIQ--vote-0000061E-QINU`"' Less reliably anticholinergic than first-generation H1s; minimal antiemetic effect. Desloratadine (Clarinex) is the active enantiomer-of-metabolite version marketed as a Rx alternative. (1) · '"`UNIQ--vote-00000A1D-QINU`"' Like other ACE inhibitors, it raises bradykinin (driving the dry cough and rare angioedema). Renally cleared; dose-adjust in renal impairment'"`UNIQ--ref-00000A1E-QINU`"'. (1) · '"`UNIQ--vote-00000AEA-QINU`"' The 24-hour half-life supports once-daily dosing with consistent overnight BP control.
