Abstract:
Hepatotoxicity associated with isoniazid and rifampicin is one of the major impediments in antituberculosis therapy. The present study explored the prophylactic and therapeutic efficacies of Spirulina maxima in isoniazid and rifampicin induced hepatic damage in a rat model. Hepatic damage induced in Wistar rats by isoniazid and rifampicin resulted in significant alterations in biomarkers of liver function, namely, bilirubin, aspartate transaminase, alanine transaminase, alkaline phosphatase, and oxidative stress markers such as superoxide dismutase, catalase, glutathione, and thiobarbituric acid reactive substances. Co-administration of Spirulina maxima along with antituberculosis drugs protected liver from hepatotoxicity due to isoniazid and rifampicin. Administration of Spirulina maxima consecutively for 2 weeks to hepatodamaged animals resulted in restoration of hepatic function as evident from normalization of serum markers of liver function. Thus, the present study revealed remarkable prophylactic and therapeutic potential of Spirulina maxima. Co-administration of Spirulina maxima and antituberculosis drugs is advantageous as it provides extra nutritional benefit.
Insights
Spirulina maxima protects against liver damage caused by tuberculosis drugs isoniazid and rifampicin. This natural supplement shows promise for both preventing and treating drug-induced hepatotoxicity.
Area of Science:
- Pharmacology
- Hepatology
- Natural Product Research
Background:
- Hepatotoxicity from isoniazid and rifampicin is a significant challenge in tuberculosis treatment.
- Drug-induced liver injury necessitates exploring protective and therapeutic agents.
Purpose of the Study:
- To evaluate the prophylactic and therapeutic effects of Spirulina maxima against isoniazid and rifampicin-induced hepatotoxicity in a rat model.
- To assess Spirulina maxima's impact on liver function biomarkers and oxidative stress.
Main Methods:
- Wistar rats were administered isoniazid and rifampicin to induce hepatic damage.
- Spirulina maxima was co-administered prophylactically or administered therapeutically to assess its effects.
- Liver function tests (bilirubin, AST, ALT, ALP) and oxidative stress markers (SOD, catalase, GSH, TBARS) were analyzed.
Main Results:
- Isoniazid and rifampicin significantly altered liver function and oxidative stress markers.
- Co-administration of Spirulina maxima protected against drug-induced hepatotoxicity.
- Therapeutic administration of Spirulina maxima for two weeks normalized liver function markers.
Conclusions:
- Spirulina maxima demonstrates significant prophylactic and therapeutic potential in mitigating antituberculosis drug-induced hepatotoxicity.
- Co-administration offers nutritional benefits alongside liver protection.
- Spirulina maxima is a promising natural agent for managing liver complications in tuberculosis therapy.
