  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In rats in the forced swimming test, BPC‑157 reduced immobility time to a degree that corresponds to the activity of imipramine.

    In plain wordsIn rats, BPC‑157 reduced immobility in the swim test about as much as the antidepressant imipramine.

    Summary
    In a forced swimming test, a reduction of the immobility time in BPC 157 (10 microg, 10 ng x kg(-1) i.p.) treated rats corresponds to the activity of the 15 mg or 40 mg (i.p.) of conventional antidepressants, imipramine or nialamide, respectively, given according to the original Porsolt's protocol.
