Description | Tebipenem Pivoxil (Orapenem) , an orally activity carbapenem antibiotic, is utilized in treating otolaryngologic and respiratory infections. |
In vitro | Tebipenem Pivoxil has high?intestinal apical membrane permeability due to plural intestinal transport routes, including the uptake transporters such as OATP1A2 and OATP2B1 as well as simple diffusion. [1] Tebipenem Pivoxil is quickly converted to tebipenem?(TBPM), an active form of?Tebipenem Pivoxil. Tebipenem Pivoxil are absorbed quickly, and the bioavailability is 71.4%, 59.1%, 34.8% and 44.9%, respectively, in mouse, rat, dog and monkey. [2] Tebipenem shows the strongest bactericidal activity as early as 2 h after exposure at two times the MIC. Tebipenem shows higher affinities for PBP 1A and PBP 2B, high-molecular-weight enzymes, and for PBP 3, a low-molecular-weight enzyme, than for PBP 2X.?[3] Tebipenem?has a potent?activity?against?Neisseria gonorrhoeae; its?activity?is comparable to it of cefixime that has most potent activity among oral antibiotics. [4] |
In vivo | Tebipenem Pivoxil results in survival rate of 83%, compared with 25% survival for Amoxicillin and 0% survival for controls in animal model of?otitis?media. [5] Tebipenem?exhibits?slow?tight-binding inhibition at low micromolar concentrations versus the chromogenic?substrate?nitrocefin.?Tebipenem?acyl-enzyme complex remains stable for greater than 90 min and exists as mixture of the covalently bound drug and the bound retro-aldol cleavage product.
