3. Participants with hepatic impairment will be classified by the Modified Child-Pugh classification with Grade B (Score7-9).
4. Participants with Normal Renal function test.
5. Negative for HIV and HCV.
6. Peripheral smear or Rapid diagnostic test negative for malarial parasite.
7. Willing to give written Informed Consent and comply with all protocol requirements.
Inclusion criteria for normal healthy participants:
1. Participants of either gender
2. Age 18-65yrs, both inclusive.

(for tuberculosis, HIV, or any drugs that have hemolytic potential in G6PD individuals including sulphonamides, dapsone, nitrofurantoin, nalidixic acid, ciprofloxacin, methylene blue, toluidine blue, phenazopyridine, and co-trimoxazole).
7. Use of antimalarials within two weeks before contact with the study team as reported by the patient.[based on history taking]
