    Side Effects & Safety

    Almost no safety data exist. The single published human study reported no significant changes in visual reaction time or motor control relative to placebo but did not publish an adverse event table (PMID: 418433). No animal toxicology study, no repeat-dose study, no genotoxicity or reproductive toxicity work and no pharmacovigilance data have been published for this compound. The absence of reported harm should be read as absence of evidence, not as evidence of safety.

    Contraindications

    None established. No toxicology, drug interaction, pregnancy, lactation, hepatic impairment or renal impairment data have been published for PRL-8-53 in humans or in animals. The only human exposure on record is a single 1978 study (PMID: 418433). With no pharmacokinetic profile and no repeat-dose data, there is no evidence base from which to define who should avoid it, which is itself a reason for caution.
