Pharmaceutical companies are those companies that are responsible for the formation of medicines and medical drugs for a country. These companies either discover or develop medicines. Not all companies which produce medicine can be considered pharmaceutical companies. The companies should take a license from the government to be considered legal companies.
The pharmaceutical company can be public as well as private. The government pharma companies get investment from the government and are own by the government.
Private pharmacy companies are own by private individuals and all the investments are made by the owner or with a joint alliance.
