Assessment of in vitro drug interactions against L. major (5ASKH strain) promastigotes

Serial no.	Drug combination	Mean $\sum \text{FICs}$a	Nature of the interaction
1	Paromomycin–suramin	0.41 ± 0.05	Synergism
2	Netilmicin–suramin	0.69 ± 0.29	Indifference
3	Primaquine–suramin	0.90 ± 0.08	Indifference
4	Primaquine–netilmicin	1.14 ± 0.2	Indifference
5	Primaquine–paromomycin	1.68 ± 0.15	Indifference
6	Paromomycin–netilmicin	2.6 ± 0.4	Indifference

Results are given as mean ± SD of three independent experiments

^aMean of $\sum \text{FICs}$ were used to define the nature of the interactions between the drugs against L. major (5ASKH strain) promastigotes
