Liquid dosage forms is pourable pharmaceutical preparations，it is also one of the oldest dosage form used in the treatment of patients and affords rapid and high absorption of medicinal products. Liquid dosage form contains a mixture of active pharmaceutical ingredients and non-pharmaceutical ingredients (excipients) dissolved or suspended in a suitable solvent or mixtures of solvents. They are administered by oral and parenteral (injection, inhalation, ophthalmology, ear canal, nasal cavity and topical) routes. Oral liquids are non-sterile, while liquids administered by parenteral routes are available in sterile and non-sterile formulations.

When developing sprays, formulation and device development go hand in hand. Changing one affects the other, and vice versa. For example, the design and geometry of the nozzle can affect the stresses placed on the suspension and thus the distribution of the spray droplets. Similarly, changes in excipients may affect the viscosity of the formulation as well as the efficiency of nozzle pumping - which is critical because drop size distribution affects where the drug is deposited in the respiratory tract and therefore its biologic efficiency and speed of onset of action. CD Formulation provides clients with expert development of spray formulations that we help our customers to rapidly develop their products and accelerate their commercialization.
