Reconstitution usually requires a reconstitution and delivery system to ensure that the drug is correctly mixed and administered. Capsules can be designed to remain intact for some hours after There are a number of methods by which tablets and capsules can be modified in order to allow for sustained release of the active compound as it moves through the Another method by which sustained release is achieved is through an These are also called injectable formulations and are used with Most protein formulations are parenteral due to the fragile nature of the molecule which would be destroyed by enteric administration.

Proteins have As with solid formulations, liquid formulations combine the drug product with a variety of compounds to ensure a stable active medication following storage.

These include solubilizers, stabilizers, Lyophilized drugs are stored in vials, cartridges, dual chamber syringes, and prefilled mixing systems.
