Doripenem, a parenteral, broad-spectrum antibacterial agent of the carbapenem family, is indicated as empirical therapy in serious bacterial infections in adults. Doripenem is indicated in Japan for use as a single agent in intra-abdominal infections (IAIs), lower respiratory tract infections (including nosocomial pneumonia), complicated urinary tract infections (cUTIs) and a variety of other bacterial infections, such as complicated skin and skin structure infections (cSSSIs), obstetric and gynaecological infections, serious ear, nose and throat infections, sepsis and endocarditis, dental and oral surgical infection, and ophthalmic infection caused by various susceptible strains of Gram-negative, Gram-positive or anaerobic bacteria. Doripenem is indicated in the US for the treatment of complicated IAIs (cIAIs) or cUTIs, including pyelonephritis, caused by susceptible strains of designated pathogens, and in the EU for the treatment of nosocomial pneumonia (including ventilator-associated pneumonia [VAP]), cIAIs or cUTIs.Doripenem has a broad spectrum of in vitro activity against Gram-positive and Gram-negative bacteria, including extended-spectrum beta-lactamase (ESBL)- and AmpC-producing Enterobacteriaceae, and anaerobic pathogens. The drug also has a low propensity to select for resistance and is suitable for the prolonged infusions that may be required to achieve pharmacodynamic/pharmacokinetic targets for bactericidal activity (and therefore efficacy) against pathogens with increased MICs (minimum concentrations required to inhibit the pathogens). Doripenem is no less effective than other antibacterial agents, including meropenem, imipenem/cilastin, piperacillin/tazobactam or levofloxacin in a wide range of serious bacterial infections, such as complicated lower respiratory infections, nosocomial pneumonia (including VAP), cIAIs and cUTIs, and is well tolerated. Thus, doripenem is a valuable addition to the options available for the empirical treatment of serious bacterial infections in hospitalized patients.

Lemierre's syndrome (LS) is characterized by pharyngitis followed by septicemia, internal jugular vein thrombophlebitis, and metastatic embolization in general. LS is commonly caused by Fusobacterium necrophorum. Herein, we present a case of LS with liver abscesses that presented as a sole metastatic lesion. We were not able to diagnose LS until Fusobacterium necrophorum was isolated due to the lack of the common involvement. Doripenem was effective against the pathologic features including the liver abscesses. LS should be taken into consideration when clinicians find liver abscesses following pharyngitis even when the common complications of LS are not detected.

Doripenem (DRPM) is one of the carbapenems which has a broad-spectrum and strong activity against Pseudomonas aeruginosa. This observational study was conducted between April 2006 and March 2007 in Japan to evaluate the efficacy and safety of DRPM 0.5 g three times a day for sepsis with neutropenia in patients with hematologic diseases. One hundred-nineteen patients were enrolled from 34 medical institutes, comprising 117 patients for safety evaluation and 104 for efficacy evaluation. Monotherapy of DRPM 0.5 g three times a day (DRPM monotherapy) was evaluated in 73 patients. The response rates of DRPM monotherapy at 72 hours and at Day 7 were 31.5% (23/73) and 67.1% (49/73), respectively. The incidence of adverse reactions including abnormal changes in laboratory values was 23.1%, and hepatic toxicity was most common. All of these adverse events were judged by the investigators as non-serious and tolerable. These results suggest that DRPM is useful for sepsis with neutropenia, though further study may be warranted.

Doripenem is a novel wide-spectrum antibiotic, and a derivate of carbapenems. It is an ideal antibiotic for treatment of serious nosocomial infections and severe sepsis for its exceptionally high efficiency and broad antibacterial spectrum of action. Doripenem is eliminated mainly by the kidneys. In cases of acute kidney injury, dosing of doripenem depends on creatinine clearance and requires adjustments. Doripenem is eliminated during hemodialysis because its molecular weight is 300-400 Da. The aim of this study was to establish the impact of continuous renal replacement therapy (CRRT) slow low-efficiency dialysis (SLED) on doripenem serum concentrations in a population of intensive-therapy patients with life-threatening infections and severe sepsis. Ten patients were enrolled in this observational study. Twelve blood samples were collected during the first administration of doripenem in a 1-hour continuous infusion while CRRT SLED was provided. Fluid chromatography was used for measurement of the concentration of doripenem in serum. In all collected samples, concentration of doripenem was above the minimum inhibition concentration of this antibiotic. Based on these results, we can draw the conclusion that doripenem concentration is above the minimum inhibition concentration throughout all of CRRT. The dosing pattern proposed by the manufacturer can be used in patients receiving CRRT SLED without necessary modifications.

Doripenem has been recently introduced in Malaysia and is used for severe infections in the intensive care unit. However, limited data currently exist to guide optimal dosing in this scenario. We aimed to describe the population pharmacokinetics of doripenem in Malaysian critically ill patients with sepsis and use Monte Carlo dosing simulations to develop clinically relevant dosing guidelines for these patients. In this pharmacokinetic study, 12 critically ill adult patients with sepsis receiving 500 mg of doripenem every 8 h as a 1-hour infusion were enrolled. Serial blood samples were collected on 2 different days, and population pharmacokinetic analysis was performed using a nonlinear mixed-effects modeling approach. A two-compartment linear model with between-subject and between-occasion variability on clearance was adequate in describing the data. The typical volume of distribution and clearance of doripenem in this cohort were 0.47 liters/kg and 0.14 liters/kg/h, respectively. Doripenem clearance was significantly influenced by patients' creatinine clearance (CL(CR)), such that a 30-ml/min increase in the estimated CL(CR) would increase doripenem CL by 52%. Monte Carlo dosing simulations suggested that, for pathogens with a MIC of 8 mg/liter, a dose of 1,000 mg every 8 h as a 4-h infusion is optimal for patients with a CL(CR) of 30 to 100 ml/min, while a dose of 2,000 mg every 8 h as a 4-h infusion is best for patients manifesting a CL(CR) of >100 ml/min. Findings from this study suggest that, for doripenem usage in Malaysian critically ill patients, an alternative dosing approach may be meritorious, particularly when multidrug resistance pathogens are involved.
