Vyndaquel

Vyndaquel Uses, Dosage, Side Effects, Food Interaction and all others data.

Vyndaquel and tafamidis meglumine (FX-1006A) are benzoxazole derivatives developed by FoldRX. Vyndaquel is structurally similar to diflusinal.

Vyndaquel was granted an EMA market authorisation on 16 November 2011 and FDA approval on 3 May 2019.

Vyndaquel stabilizes transthyretin tetramers, reducing the amount of monomers available for amyloidogenesis. It has a long duration of action as it is given once daily, and a wide therapeutic window.

Uses

Vyndaquel is a medication used to treat transthyretin-mediated amyloidosis.

Vyndaquel is indicated to treat cardiomyopathy of wild type or hereditary transthyretin-mediated amyloidosis in adults.

Vyndaquel is also used to associated treatment for these conditions: Cardiomyopathy

How Vyndaquel works

Genetic mutations or natural misfolding of transthyretin destabalizes transthyretin tetramers, leading to their dissociation and aggregation in tissues, and disrupting the normal function of these tissues. Vyndaquel binds to transthyretin tetramers at the thyroxin binding sites, stabilizing the tetramer, reducing the availability of monomers for amyloidogenesis.

Toxicity

Data regarding overdoses of tafamidis are not readily available. In a clinical trial, some patients were given up to 6 times the normal dose with one reported case of mild hordeolum.

Food Interaction

Take with or without food.

Volume of Distribution

The apparent volume of distribution at steady state is 18.5L.

Elimination Route

Vyndaquel reaches a C_max of 1430.93ng/mL with a T_max of 1.75h fasted and 4h fed. The AUC of tafamidis is 47,864.31ng*h/mL.

Half Life

The half life of tafamidis is 49h.

Clearance

The oral clearance of tafamidis is 0.263L/h. The apparent total clearance is 0.44L/h.

Elimination Route

A 20mg oral dose of tafamidis is approximately 59% recovered in the feces, largely as unchanged drug. Approximately 22% of a 20mg oral dose is recovered in the urine, mostly as the glucuronide metabolite.
