That is an interesting question. According to the   Shazam/Prime   article:

'' "Note that during Shazam's passive, he is immune to most forms of power drain, but  Ra's Al Ghul's Dagger ,  Sinestro/Antimatter,  and  Black Adam/ Kahndaq   will  drain his power, causing him to fall below the otherwise unmovable two bars of power." ''

I personally tested out my Shazam/Prime against a Black Adam/Regime; Black Adam's power drain had no effect whatsoever while Shazam's passive was activated.
