The price of heparin sodium is influenced by multiple factors. Heparin sodium, a crucial anticoagulant, is derived mainly from porcine intestine mucosa. Fluctuations in the supply and quality of this raw material can have a significant impact on its price. For example, diseases affecting pigs can lead to shortages and thus price hikes.

　　Manufacturing processes also play a role. Sophisticated extraction, purification, and quality control procedures add to the production cost, which in turn affects the price. Stringent regulatory requirements mean that companies must invest in compliance, and these costs are often reflected in the price.

　　Market demand and competition are other key aspects. High demand in the medical field, especially for treating thrombotic disorders and during surgeries, can drive prices up. Conversely, intense competition among manufacturers may lead to price adjustments to gain market share.

　　Geographical differences also exist. Prices can vary from one region to another due to differences in production costs, regulatory policies, and market dynamics. For instance, in some countries with high production costs or strict regulations, the price of heparin sodium may be relatively higher.

　　In conclusion, the price of heparin sodium is a complex outcome of raw material supply, manufacturing, market forces, and regulatory factors, all of which interact to determine its final cost in the market.
