For topical use
Initial U.S. Approval: 2011
DESCRIPTION
NATROBA (spinosad) Topical Suspension, is a slightly opaque, light orange colored, viscous topical suspension.

Spinosad, the active ingredient, is derived from the fermentation of a soil actinomycete bacterium, Saccharopolyspora spinosa.

Spinosad is a mixture of spinosyn A and spinosyn D in a ratio of approximately 5 to 1 (spinosyn A to spinosyn D).

Spinosad causes neuronal excitation in insects. After periods of hyperexcitation, lice become paralyzed and die.
