Under this mode, the pharmacy enterprise search for its national or regional general agent and use the agent's market network to sell its products. Such kind of distribution mode can be called "the regional general agent mode." The pharmacy enterprise usually entrusts its general agent with the sale of its products through a bidding process or forming alliance with the agent, providing it products at a bottom price. The agent, after buying a certain amount of products, win the authorization from the pharmacy company to sell in a specific region and becomes its sole authorized agent in the region. The regional general agent can be the general wholesaler in a big region, provincial wholesaler, district wholesaler or municipal wholesaler, etc. In a big region or in a province, regional general agents provide patients with their products through sub-wholesalers and retailers. In a small place such as a county, products can go directly from the regional general agent to retailers and then to patients, without the involvement of sub wholesalers.
