• Formulation concept & method:
➢ They may be solutions in water, mixtures of water with cosolvents
(propylene glycols, PEG, alcohol, ...), or other nonaqueous/oily
solvents.
➢ They are manufactured by dissolving the drug and any excipients,
adjusting the pH, sterile filtering the resultant solution (to also
remove particulate matter), then autoclaving the final product in its
sealed container.
