The Vietnamese word "biệt dược" refers to a type of medicine that is patented or proprietary, meaning it is specially formulated by a particular company and is not available from other sources. This term is often used in the context of pharmaceuticals and healthcare.
In a more advanced context, "biệt dược" can be discussed in terms of its effectiveness, regulations regarding patenting in the pharmaceutical industry, or its role in the global market. For example, one might say: - "Sự phát triển của biệt dược đã thay đổi cách tiếp cận điều trị bệnh trong y học hiện đại." - (The development of proprietary medicines has changed the approach to disease treatment in modern medicine.)
While "biệt dược" primarily refers to patented medicines, in some contexts, it can also imply exclusivity or specialty in other fields, though this is less common.
