In Vitro
Tobramycin (0-50 ng/mL; 24 hours) sulfate combinates with mycobacterium fortuitum enzyme (PodA) can greatly decreases P. aeruginosa cell viability[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Tobramycin (s.c., single dose) sulfate LD50 values in mice and rats are 441 and 969 mg/kg, respectively[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Murine Model of Pseudomonas aeruginosa Pneumonia Female, Swiss-Webster mice [3]
-
Dosage:50, 100, 150, 214, and 400 mg/kg/day
-
Administration:Intraperitoneal injection (i.p.) ,once every 4h
-
Result:Had near-maximal killing of the wild-type bacteria occurred at approximately 150 mg/kg/day when tobramycin alone.
Combinated with Meropenem (HY-13678) produced near-maximal effect (i.e., bacterial cell kill) at low doses of both drugs (60 and 50 mg/kg/day for Meropenem (HY-13678) and tobramycin, respectively).
-
Animal Model:Mice, rats, cats and dogs for toxicologic evaluation[4]
-
Dosage:7.5,15,30,120,441,969 mg/kg
-
Administration:Subcutaneous injection (s.c.), Intravenous injection (i.v.) ,Intramuscular injection(i.m.)
-
Result:The s.c. LD50 values in mice and rats were 441 and 969 mg/kg, respectively.
Within 1 hour after treated, death with central nervous system depression as a precursor occurred in rats and mice.
A 100 mg/kg iv dose in chloraloseanesthetized catsproduced a moderate, transient decreasein blood pressure and a significant decrease in inspiratory volume and soleus twitch force.
Changed renal tissue in rats which were given daily sc doses of 15-120 mg/kg for 3 months.
im dose of 7.5 mg/kg for a l-month had no apparent effect on dogs, but a 30 mg/kg dose for a l-month produced severerenal damage.
