No, the patent only shows that you have a certain technical content (only the application number does not mean that the country must recognize your technical content, only authorization means recognition), while opening a store involves the approval of the drug supervision department, medical qualifications, business licenses of the tax department and the industrial and commercial department, so everything is fine without the application number.
On the other hand, even if you don't apply for a patent, you can open a store for sale if you meet the above adjustments. There is no need to apply for a patent.
