ABSTRACT
Many active pharmaceutical ingredients (APIs) exist in the solid-state or are
formulated into solid dosage forms. This confers several advantages: stability
in the solid-state is usually greater than in the liquid state; solids are easier to
process, transport, package, and store; and the majority of medicines, at least
in the United Kingdom, are formulated as tablets as the oral route is both
quick and has a high degree of patient compliance.
