Applicant's summary and conclusion

Conclusions:

Under the conditions of this study the median lethal dose of (R)-1-Phenylpropylamin after oral application was found to be greater than
200 mg/kg and less or equal to 500 mg/kg body weight.

Executive summary:

To two groups each of three fasted animals (males) a single oral dose of the test material preparation in olive oil DAB 10 at dose levels of 500 and 2000 mg/kg body weight was given. Another group of six fasted animals (3 males and 3 females) was treated in the same way with a dose of 200 mg/kg body weight. Signs of toxicity noted in the 2000 and 500 mg/kg dose group comprised poor general state, dyspnoea, apathy, ataxia and paresis. Twitching, saltatory spasm and flexion spasm were additionally observed in rats of the 2000 mg/kg dose group. Symptoms observed in the 200 mg/kg dose group comprised impaired or poor general state, dyspnoea, apathy and staggering. The surviving animals appeared normal within 5 hours after application. The expected body weight gain was observed in the course of the study. All animals of the 500 and 2000 mg/kg dose group died within 1 hour after application. No mortality occurred in the 200 mg/kg dose group.

Necropsy findings of the animals that died comprised severe hyperemia in the glandular stomach and hyperemia of the mucosa in the small intestine (2000 mg/kg). No abnormalities were noted at necropsy of animals sacrificed at the end of the study and of the animals of the 500 mg/kg dose group that died. Under the conditions of this study the median lethal dose of (R)-1-Phenylpropylamin after oral application was found to be greater than 200 mg/kg and less or equal to 500 mg/kg body weight.
