text: Yo, check it out, listen up, I got something to say,
  About viral infections, in the AIDS patients' way.
  Herpes virus be causin' trouble, that's a fact,
  Up to 16% of infections, that's the impact.
  
  Acyclovir, the solution, it's the real deal,
  Treating herpes simplex, and herpes zoster, for real.
  Now we got some new analogues, fresh and bold,
  Desciclovir, metabolized to acyclovir, as we're told.
  
  Oral prodrug, packin' a punch, virus infections we fight,
  Epstein-Barr ain't got no chance, we takin' flight.
  High serum levels, that's what we need,
  To battle these infections with lightning speed.
  
  BW B759U, another analogue in the mix,
  Fightin' cytomegalovirus, it's a risky fix.
  AIDS patients, their lives at stake,
  But this treatment brings stability, no mistake.
  
  Retinitis patients, they see the light,
  With over 80% stabilized, it's a beautiful sight.
  Antiviral power, proven in seventy-three,
  This treatment's got the efficacy, can't you see?
  
  Now let's talk 'bout azidothymidine, it's the key,
  Developed for HIV, that's the guarantee.
  Reverse transcriptase, it's the target, no doubt,
  Phase I studies showed it's well tolerated throughout.
  
  Crossin' the blood-brain barrier, it's got the skill,
  To fight HIV in the brain, that's the thrill.
  Efficacy trials, we're workin' on that front,
  But this candidate's lookin' promising, no stunt.
