DL-Penicillamine [(±)-Penicillamine] is a copper chelating agent. DL-Penicillamine has antidotal effects in thallotoxicosis rats when co-treated with Prussian blue . DL-Penicillamine can cause pyridoxine deficiency and then induce optic axial neuritis. DL-Penicillamine can also depress primary immune response[1][2][3].
DL-Penicillamine (25 mg/kg; i.p.; twice daily, for 5 days) has antidotal effects in thallotoxicosis rats when co-treated with Prussian blue [2].
| Animal Model: | Male Wistar rats, NIH strain (intoxicated by i.p. injection of 32 mg/kg thallium (I) acetate)[2] |
| Dosage: | 25 mg/kg |
| Administration: | i.p.; twice daily, for 5 days |
| Result: | Decreased slightly the thallium content in blood, organs and brain. Increased the probability survival when co-treated with Prussian blue (50 mg/kg; p.o.). |
