Sodium picosulfate in enema

As I understand Sodium picosulfate very similar to bisacodyl, which we can use to stimulate peristaltic in enema. But I can't find any evidence of use Sodium picosulfate, which can be used as bisacodyl. But only at first enema, because bacterias at colon activate it....

What do you think about it, logically it can be used same as bisacodyl...

I have bought it in Peru and it has instructions on how many drops to add to an enema
