Effects of Moringa (Moringa oleifera) on the pharmacokinetics of nevirapine in HIV-infected adults: A clinical study

 

by Organic Kosha February 25, 2021

 The present study was carried out to investigate the efficacy and safety of the Effects of Moringa (Moringa oleifera) on the iron status of Senegalese lactating women.

 

Background

Moringa oleifera Lam., an herb commonly consumed by HIV-infected people on antiretroviral therapy, inhibits cytochrome P450 3A4, 1A2 and 2D6 activity in vitro; and may alter the pharmacokinetics (PK) of antiretroviral drugs metabolized via the same pathways. However, in vitro drug interaction activity may not translate to a clinically significant effect. Therefore, the effect of moringa leaf powder on the PK of nevirapine in HIV-infected people was investigated.

Treatment Offered    

Adult patients at steady-state dosing with nevirapine were admitted for 12-h intensive PK sampling following a 21-day herbal medicine washout. Blood sampling was repeated after 14 days of nevirapine and moringa (1.85 g leaf powder/day) co-administration. Nevirapine plasma concentrations were determined by liquid chromatography-tandem mass spectrometry. To assess the effect of moringa on nevirapine PK, the change in nevirapine area under the plasma concentration-time curve (AUC) was determined. The mean difference in pre-and post-moringa nevirapine, maximum concentration (Cmax), and concentration at 12 h (C12h) were also calculated. The PK parameters were compared by assessing the post/pre geometric mean ratios (GMRs) and associated 90% confidence intervals (CIs).
 

Results

 
Pharmacokinetics analyses were performed on the results from 11 participants for whom complete data were obtained. The post/pre-GMRs and associated 90% CIs for nevirapine were 1.07 (1.00–1.14) for the AUC; 1.06 (0.98–1.16) for Cmax and 1.03 (0.92–1.16) for C12h.
 
Characteristic Value
Age (years), mean ± SD 44 ± 8
Sex, female, n (%) 8 (73)
Weight (kg), mean ± SD 63.5 ± 7.5
Drug frequency n (%)
 Nevirapine 13 (100)
 Tenofovir/lamivudine 10 (77)
 Stavudine/lamivudine 2 (15)
 Zidovudine/lamivudine 1 (8)
 Cotrimoxazole 9 (69)
 Other drugs 3 (23)

Conclusion 

 

Co-administration of Moringa oleifera Lam. leaf powder at the traditional dose did not significantly alter the steady-state PK of nevirapine.
