Telepharmacy refers to providing pharmaceutical care with the help of digital technology and telecommunication to persons who cannot access pharmacists physically. This becomes crucial in reducing healthcare disparities as we can ensure equitable access to pharmaceutical care for those in remote settings. Even though telepharmacy has a broad scope and massive utility in reducing healthcare disparities, multiple challenges have been reported in the process of implementation. In conclusion, telepharmacy is an approach to bridge the existing gaps in healthcare delivery, enabling patients to receive holistic pharmaceutical services irrespective of their geographical location.
