RegisterPentosan Polysulfate Sodium Bioequivalence study [Regulatives / Guidelines]
Dear Raja
In fact you can not perform a bioequivalence study if the drug is not systemically available due to very poor resorption (Bioavailability 0.4 - 3%). If a drug exhibits limited absorption but is highly soluble you could perform a BCS class III biowaiver. But to my knowledge this does not apply to pentosan polysulfate. So the only way to show therapeutic equivalence is to perform a pharmacodynamic or a comparative efficacy study.
Kind regards
Dan
