Whereas the non-sterile compounded drugs segment will expand at the fastest CAGR. Inclusion of those products, where there is no need to maintain sterility conditions, like oral and topical formulations, especially capsules, solutions, suspensions, ointments, creams, and suppositories, is bolstering the segmental expansion.
