Abstract:
The years 2020 and 2021 have witnessed a COVID-19 pandemic caused by the SARS-CoV-2 virus. However, these years have also witnessed certain remarkable scientific achievements. Researchers across the globe have been trying extremely hard and accomplished in bringing vaccines a great variety of COVID-19 vaccines. Though the route of administration for the majority of these vaccines has been the intramuscular route (invasive), some laboratories are developing formulations intended for transmucosal and transcutaneous (non-invasive) administration, which are in the early phases of pre-clinical and clinical development. This short report discusses these unconventional formulations against COVID-19, in brief, to stress the importance of research in the field of drug delivery.

Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Drug Delivery: Overview
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
