Look at what LSD actually is before checking the drug options. It is a pox virus infection of cattle, spread mainly by biting insects. None of Amantadine, Cidofovir or Tenofovir has approval or established field use for this disease, since these drugs target unrelated viruses. Current management of LSD relies only on supportive treatment, wound care and control of secondary infection, plus vaccination for prevention, not on a curative antiviral. $\boxed{\text{No Drug Available}}$
