Ribaviz capsules is a generic product with Ribavirin 100, 200, and 400 mg. Similar to inosine and adenosine, ribavirin is an analogue of guanosine nucleoside that is insoluble in water. It is transported systemically after intestinal absorption, which is assisted by nucleoside transporters on luminal epithelial cells.
Two types of nucleoside transporters have been linked to ribavirin uptake that is equilibrative and concentrative nucleotide transporters. One significant difference between these two transporters is their sodium dependency.
Concentrative nucleotide transporters are sodium dependent, meaning that nucleotide importing is related to sodium irrespective of nucleoside concentrative, whereas equilibrative nucleotide transporters allow for both directions of sodium-independent transport. Furthermore, CNTs have a high sensitivity for nucleosides, whereas ENTs are ENTs are low-resemblance transporters. There are many major differences in these chemical structure connections.
Ribavirin functions as a mutagen in the area of viruses, resulting in an ‘error catastrophe’ because of enhanced viral mutations. Ribavirin triphosphate combines with cytidine triphosphate or uridine triphosphate with similar ability to inhibit hepatitis C virus RNA replication. It in advance terminates HCV RNA and promotes mutagenesis by generating virions 7. The act of altering an organism's DNA, known as mutagenesis, has the potential to cause genetic mutation. These mutations may occur in noticeable alteration in the features.
Additionally, by changing the host's immune response from a Th2 to a Th1 phenotype, ribavirin modifies the host's reaction to the virus. The Th2 response and the synthesis of type 2 cytokines including IL-10, IL-5, and IL-4 assist the humoral response. Ribavirin increased the expression of interferon-related genes, including the many receptors, while decreasing the expression of genes related to inhibition, apoptosis, and hepatic stellate cells.
