capsule

I'm a little stuck... Click here to teach me more about this clue!

'medicine' is the definition.
(capsule is a kind of medicine)

'distressed pal's cue' is the wordplay.
'distressed' indicates an anagram.
'pals'+'cue'='palscue'
'palscue' anagrammed gives 'CAPSULE'.

'to get case containing' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for capsule that I've seen before include "Gelatine case for medicine" , "Gelatinous container with medicine inside" , "Soluble case containing medicine" , "Lozenge - space vehicle" , "Space crew return in it" .)
