Thanks for query,
As you give an example trial study of lactobacillus
combination with other drugs.
I would like to tell that go for combination of Lactobacillus where the drug used may disturb intestinal flora.
here we give lactobacillus as a supplement to correct int. flora.
Combination of lactobacillus with metronidazole
or anti fungal is irrational as i do not think either of any drug disturb int. flora.
So please keep this thing in the mind and go ahead.
Good luck and bye.
