Do you see any any this kind of drug? Or why you need to develop a drug with >24 hr half life? We develop sustained release drug, but can't achieve this goal.
The drug is not mention here but as the drug has 24 hours of half life then it is already sustained release even if you are formulated in conventional form.
It is also not mention that up to what period you wish to release your drug and what dosage form you wish to develop.
As the category and class of drug is also not mention hence it is of no rational to develop formulation of the drug having half life more than 24 hours.
