Human metabolism of zamicastat, an oral dopamine β-hydroxylase inhibitor.
(PubMed, Drug Metab Dispos)
- "Few minor metabolites were identified in circulation. Across species in vitro studies have shown a completely different profile from human metabolism with only trace levels of [14C]-thiocyanic acid observed, precluding the prediction of the extensive zamicastat metabolism observed in humans."

Metabolism and disposition of zamicastat in rats.
(PubMed, Xenobiotica)
- "Zamicastat metabolic pathway involved multiple reactions comprising desulfurization, oxidative desulfurization, N-debenzylation followed by further oxidation or N-acetylation, and the unexpected multistep metabolic pathway leading to isocyanic acid/thiocyanic acid.As main conclusion, zamicastat was found to be rapidly absorbed, widely distributed to peripheric tissues and almost completely recovered after 168 h post-dose, mainly via faeces. It is extensively metabolized by multiple reactions with isocyanic acid/thiocyanic acid as the major late metabolite."

Drug-Drug Interaction between Oral Zamicastat and Continuous Epoprostenol Infusion at Steady-State Conditions in Healthy Subjects.
(PubMed, J Clin Pharmacol)
- "ISCV was between 30% and 41% for Cmax,ss and between 21% and 41% for AUC0-τ,ss, for zamicastat and both metabolites. This study showed that the administration of zamicastat did not significantly modify the cardiovascular effects of epoprostenol and that the interactions between zamicastat and epoprostenol are not expected to be clinically relevant."

Dopamine regulates neuroendocrine cell expansion in the developing lung
(ENDO 2023)
- "Treatment with Metyrosine (Met) and Benserazide (Benz) which inhibits dopamine production, resulted in a striking increase in PNEC number in NEBs as seen by expansion in Ascl1+ cells, without affecting cell proliferation. By contrast, no effect was observed with Zamicastat (Zami) which inhibits norepinephrine production. To examine whether dopamine regulated PNEC differentiation, we used the D1-like receptor antagonist, SCH-23390 and the D2-like receptor antagonist, Haloperidol in lung explant cultures, as before...Abstracts presented at a news conference are embargoed until the date and time of the news conference.

[VIRTUAL] PHASE 1 STUDY TO INVESTIGATE THE EFFECT OF P-GLYCOPROTEIN TRANSPORTER INHIBITION MEDIATED BY CARVEDILOL ON THE PHARMACOKINETICS OF ZAMICASTAT
(CHEST 2021)
- "Co-administration of carvedilol, strong inhibitor of P-gp, had no substantial effect on the rate and extent of exposure of zamicastat and therefore it is expected that such interaction is devoid of therapeutic impact. CLINICAL IMPLICATIONS: P-glycoprotein (P-gp) is a clinically important efflux transporter extensively expressed in various tissues including the gastrointestinal tract, liver, kidney and brain, which has the potential to impact the oral bioavailability, tissue distribution, hepatic and renal elimination of substrates. Zamicastat is a reversible dopamine β-hydroxylase inhibitor, that modulate sympathetic nervous system by reducing norepinephrine biosynthesis in peripheral sympathetic nerves, which was granted Orphan Drug Designation by Food and Drug Administration for the treatment of Pulmonary Arterial Hypertension."

(CHEST 2021)
- "Zamicastat showed a linear dose-PK relationship up to 400mg. The micronization of the API, food and age were found to increase the plasma exposure of Zamicastat. The activity of DβH was inhibited in plasma in a dose-dependent manner."
