Anti-Snake Venom Properties of Medicinal Plants: A Comprehensive Systematic Review of Literature

Abstract Snakebite is one of the major health issues posing considerable morbidity and mortality. According to an estimate of World Health Organization (WHO) (World health organization, 2021) approximately 5 million people are bitten by several species of snakes resulting in up to 2.5 million envenomation cases annually. The mainstay of treatment for envenomation is intravenous administration of anti-snake venom. Although antivenom neutralizes the systemic effects but it does not relieve the symptoms such as venom-induced hemorrhage, necrosis and nephrotoxicity. Moreover, the use of antivenoms is associated with hypersensitivity reactions including urticaria, anaphylaxis, or serum sickness due to their heterologous property. Furthermore, stringent storage conditions and narrow specificity of antivenoms limit their use in both developed as well as developing countries. In this context, researchers have been searching for natural products and plant extracts to explore their antivenom activity along with anti-myotoxic, anti-hemorrhagic and anti-inflammatory properties. Plant remedies may prove to be an effective alternate for antivenom sera with less adverse events and better tolerability. To the best of our knowledge, this is the first comprehensive review of medicinal plants possessing anti-snake venom activities against certain species of snakes. The current review highlights the investigated plants with their phytochemical analysis to integrate the available information for future research and development of antivenom sera.

Multilevel Engagements of Pharmacists During the COVID-19 Pandemic: The Way Forward.

Severe acute respiratory syndrome caused by the novel coronavirus (SARS-CoV-2) was first reported in China in December 2019 which was later declared to be a public health emergency of international concern by the World Health Organization (WHO). This virus proved to be very contagious resulting in life-threatening respiratory intricacies posing overall public health and governance challenges. Amid the coronavirus pandemic and the unprecedented increase in healthcare demands, only inventive and adaptive practice among healthcare professionals is the need of the hour. Pharmacy services are an important mainstay in the public health and have considerable potential to combat the coronavirus disease 2019 (COVID-19) pandemic. Pharmacists working in several localities and health facilities are linked to patients either directly or indirectly. They can act swiftly in public health response such as drafting professional service guidance to pharmacists working in various healthcare facilities, ensuring effective medicine supply system, monitoring and resolving drug shortage issues, establishing and promoting remote pharmacy services, counseling the public on infection prevention basics, educating about proper use of personal protective equipment, discouraging self-medication, participating in clinical trials, small-scale manufacturing of sanitizers and disinfectants, busting the prevailing myths, and conducting drug evaluation and active surveillance. These interventions will help ease unprecedented burden on healthcare facilities during the ongoing pandemic and eventually will add value to patients and the healthcare system. The current manuscript accentuates the potential roles and activities that pharmacists can initiate in various healthcare facilities to help in relieving pressure on the overwhelmed healthcare system. The information and suggestions offered in this review could help in the restructuring of existing pharmacy services by governments, public health bodies, and policy makers in response to the COVID-19 pandemic. Moreover, this manuscript will underscore any unrealized potential among pharmacists working in various sectors including community, hospital, industry, and drug regulatory authorities.
