Bioequivalence and Bioavailability Forum

Hi to all,
when we get investigational product from the sponser, we not get information about IP's is light sensitive or not? for this i refere indian pharmacopoeia and British pharmacopoeia, in this many drugs labeled as "PROTECT FROM LIGHT" OR "STORE IN LIGHT RESISTANCE CONTAINER" it means this IP's should dispense in the monochromatic light e.g. Sodium vapour lamp? So can I all this IP's dispense in the monochromatic light? And what about film coated tablet in which key ingredient is light sensitive? or it is only necessery for drug in plasma/blood which is sensitive to the light?
Please give your best suggestion...

thank you and regards,
Santosh A.
