How do I prepare the next solution? Bacitracin 40000iu triamcinolone 100 mg nystatin 100000iu NaCl 0.9% AD 10 ml MFA ear drops for middle ear

For the middle ear, sterile isotonic ear drops are administered, which do not contain any unresolved particles. For me, this composition is not suitable when the eardrum is perforated. And this for various reasons. I would discuss this matter with the NKO doctor. In fact, I must confess that I do not know which ear drop is still eligible for an intermediate ear infection with perforation of the eardrum. According to the literature no more. All the classic ear drops, which I checked, give as contraindication: perforated eardrum.
