Analytics and science-based approaches are shedding more light on these complex dosage forms, promising to improve process control and product design.
Ointments and creams may be as old as humanity itself, but their formulation is extremely complex. In a category of their own, these semisolids involve many more ingredients than other dosage forms, and materials in different phases, increasing the potential for variability and interactions. As a result, achieving process understanding and control is more difficult with these materials than it might be for simpler solid dosage form.
