A hospital may manufacture sterile and non-sterile products internally based on economic factors and patient needs. For sterile products like parenterals, the hospital needs facilities for clean rooms, environmental controls, and sterilization methods like UV irradiation. Production planning involves cleaning equipment and containers, preparing solutions/suspensions, filtration, filling, sealing, and sterility testing. Non-sterile manufacturing follows less stringent rules but can still be economical for high-volume needs like oral liquids. The type and size of a hospital determines what products it manufactures internally.
