  A practical number is a positive integer $n$ such that all positive integers
less than $n$ can be written as a sum of distinct divisors of $n$. Leonetti and
Sanna proved that, as $x \to +\infty$, the central binomial coefficient
$\binom{2n}{n}$ is a practical number for all positive integers $n \leq x$ but
at most $O(x^{0.88097})$ exceptions. We improve this result by reducing the
number of exceptions to $\exp\!\big(C (\log x)^{4/5} \log \log x\big)$, where
$C > 0$ is a constant.
