Arbitol hydrochloride (AH) is a potent medication used for preventing and treating respiratory virus infections, particularly influenza A and B. Its chemical name is 6-bromo-4-(dimethylamino-methyl)-5-hydroxy-1-methyl-2-(phenylthiophenyl)-1H-indole-3-carboxylic acid ethyl ester hydrochloride, and it is stabilized using hydrochloric acid. This compound has a molecular formula of C22H25BrN2O3S•HCl and a molecular weight of 531.90.
The convenience of oral administration, high safety profile, excellent compliance, and lack of cytotoxicity make Arbitol hydrochloride a very promising drug. It has a wide range of potential uses in the medical field. The impact of the COVID-19 outbreak in Wuhan was felt by everyone, greatly affecting their psychological state. However, with the united efforts of the entire country, we have successfully controlled the epidemic. A significant milestone in this battle was the release of the sixth edition of the Novel Coronavirus Pneumonia Diagnosis and Treatment Protocol (Trial) on February 19. This new version highlights our progress in developing standardized protocols and approaches to combat this novel infectious disease. Notably, the sixth edition introduces two "new" drugs, namely chloroquine phosphate and arbitol. These additions demonstrate our continuous efforts to improve the treatment options available and provide hope in the face of this challenging situation.
Chloroquine phosphate has been known for years as a medication used in the treatment of malaria and autoimmune diseases. What many people may not realize is that this drug also has the ability to block viral infections by raising the pH level in the endosome, which is necessary for the fusion of the virus with the cell. Moreover, chloroquine exhibits strong immunomodulatory activity, which can work together with its antiviral effects to provide a powerful shield against viruses. These properties make chloroquine phosphate a promising candidate for the prevention and treatment of viral diseases.
The inclusion of Arbidor has been controversial.Developed by the former Soviet Union's Medical Chemistry Research Center, Arbidol is an antiviral medication primarily used for treating influenza caused by A class A, B viruses. Additionally, it exhibits potent antiviral effects against various respiratory viruses, displaying broad-spectrum characteristics. This drug's efficacy extends beyond influenza, encompassing other respiratory virus infections. Its antiviral activity contributes significantly to its reputation as a powerful treatment option.
Arbidol is an antiviral drug that effectively targets influenza A and B viruses by inhibiting the fusion of their genetic material with the host cell membrane. Its mechanism of action is dependent on its interaction with the hemagglutinin (HA) protein, which acts as the receptor for these influenza viruses. However, it should be noted that the Novel Coronavirus lacks the HA protein on its surface. This raises questions about the validity of Arbidol's efficacy against this particular virus, as blocking the entry of the virus into human cells through the same mechanism may not be applicable.
