Daily oral administration to Sprague Dawly rats for 4 weeks of DWP-301, at doses of 0, 500, 1000, 2000 mg/kg presented following results; 1) No animals died and there were no significant differences in general signs, body weight, food consumption, urinalysis haematological, biochemical, gross pathological and histopathological examination between control and treated rats. 2) Water consumption, pH-, protein- urobilinogen-, ketone-values in urine were significantly increased in the treated male and female rats. It is supposed that these differences in animals are a consistent feature of repeated overdosage with test suspensions. The results indicate that the non toxic dose of test compounds in rats is over 2000 mg/kg in this test system.

On the combination of antacid, the pharmacokinetics and gastric adhesion of $\^$14/C-aceglutamide aluminum complex($\^$14/C-AGA) were examined in rats. Specially, This study was focused on the drug interaction that the coadministration of antacid may affect the oral absorption and gastric adhesion of aceglutamide aluminum complex(AGA). After the oral administration of $\^$14/C-AGA and antacid to rats, the radioactivity of plasma and urinary recovery was lower than that of $\^$14/C-AGA administered group. Relatively, the cumulative recovery of radioactivity in feces was increased significantly. The comparative bioavailability of $\^$14/C-AGA from the plasma concentration-time curve and urinary recovery was about 60%. in vitro, the effect of antacid in the gastric adhesion of AGA was not significantly different between AGA and AGA/antacid treatment. And it accorded well with the result of in vivo experiment. In conclusion, on the combination of antacid, the oral absorption of AGA was decreased but the gastric adhesion was not affected in respect of drug interaction.

The general and some pharmacological actions of DWP 301 were investigated in animals and the following results were obtained. In central nervous system, DWP 301 had no effects on the pentobarbital induced anaesthesia, rotarod test, traction test, analgesic action, anticonvulsant action in mice and body temperature in rat. But DWP 301 showed a little decrease of locomotor activity at a dose of 3,000 mg/kg. From these results, DWP 301 was considered to have little pharmacological effect on the central nervous system. Furthermore, DWP 301 had no influences on the normal blood pressure and heart rate. DWP 301 showed no effect on the isolated guinea pig ileum, trachea, right atrium, and nonpregnant rat uterus. But, in the isolated guinea pig vas deference, DWP 301 had showed inhibitory effect on the contractions produced by norepinephrine. DWP 301 showed rise of gastric juice pH and decrease of urine volume. Also, DWP 301 had no effect on the gastrointestinal motility and blood aggregation. From these results, it is concluded that the general pharmacological effect of DWP 301 are similar to or weaker than M and AGA.
