How it works

From the US prescribing label for the same active substance (LASTACAFT). It describes the substance, not this exact product.

Alcaftadine is an H 1 histamine receptor antagonist and inhibitor of the release of histamine from mast cells.

Decreased chemotaxis and inhibition of eosinophil activation has also been demonstrated.

Half-life2 h
Mostly cleared after≈ 10 hfive half-lives — our arithmetic
How the body breaks it down

The metabolism of alcaftadine is mediated by non-CYP450 cytosolic enzymes to the active carboxylic acid metabolite.

How it leaves the body

Based on data following oral administration of alcaftadine, the carboxylic acid metabolite is primarily eliminated unchanged in the urine.
