Special imports refer to the process by which medicines or pharmaceutical products are brought into a country under specific circumstances or conditions. These circumstances typically involve situations where the required medication is not readily available within the country's regular supply chain or where the patient requires a particular formulation or dosage that is not locally manufactured or distributed.

Orphan drugs are medications developed to treat rare diseases or conditions that affect a small percentage of the population. These diseases are often overlooked by pharmaceutical companies due to the limited market potential, making it financially unattractive to invest in research and development for treatments.
