How often do secondary drug wholesale distributors buy their drugs directly from manufacturers?

Secondary drug wholesale distributors typically purchase drugs from manufacturers sometimes, rather than on a fixed schedule of regularity. The relationship between secondary wholesalers and manufacturers can depend on a variety of factors, such as demand fluctuations, contracts, and the overall market environment. Distributors often source from a variety of suppliers to maintain inventory levels and respond to changes in the healthcare landscape or drug availability.

While secondary wholesalers can buy directly from manufacturers, they often rely on other sources like primary wholesalers or market transactions to fulfill their inventory needs. This flexibility allows them to accommodate different product lines and respond to market dynamics effectively, thus making 'sometimes' the most accurate depiction of their purchasing behavior.
