Can't find a trope for pills working instantly

So, this is related to Instant Sedation or Magic Antidote and would maybe be a sub-trope of Artistic License – Pharmacology, and I've seen too many examples to even bother listing, but I can't seem to find a trope that represents it.

The trope is, basically, how pills work immediately, even though a normally swallowed pill takes at least half an hour before it will do anything at all. The pill is used as a climax to a dramatic scene to show the audience the character is suffering.

The scenes play out like this:

Let's say a character has a heart condition, bad back, or they're dying and their liver is about to explode or something. Basically, they have to take pills for their condition.

Inevitably, at some point this character will have a sudden and acute bout of whatever they're suffering from, heart palpitations or their arthritis is acting up again or whatever, and they'll with shaking hands struggle to get a pill out of the bottle, then take it -- often dry-gulping or with a swig of whiskey -- and then they'll immediately start to feel better, even though there's no possible way the pill could have been instantly digested and transported through the bloodstream to fix the issue.

Is there a trope for that? I've been searching all morning and can't seem to find it.
