Insights

Doripenem, a new carbapenem antibiotic, demonstrated favorable safety and tolerability in clinical trials for serious nosocomial infections. This new antibiotic showed a low risk of seizures, comparable to existing treatments.

Area of Science:

  • Infectious Diseases
  • Pharmacology
  • Clinical Trials

Background:

  • Carbapenems are crucial for treating severe nosocomial infections.
  • Seizures are a primary safety concern with carbapenem antibiotics.
  • Doripenem is a novel carbapenem with preclinical evidence of low neurotoxicity.

Purpose of the Study:

  • To evaluate the safety and tolerability of intravenous doripenem.
  • To compare doripenem's safety profile against active comparator drugs.
  • To assess the seizure risk associated with doripenem administration.

Main Methods:

  • Phase 2 and 6 Phase 3 clinical trials were conducted.
  • Safety data were collected from 1817 patients receiving doripenem.
  • 1325 patients received active comparator drugs.

Main Results:

  • Intravenous doripenem was found to be safe and well-tolerated.
  • Doripenem exhibited a safety profile comparable to comparator agents.
  • Doripenem demonstrated a limited propensity to induce seizures, irrespective of infusion duration.

Conclusions:

  • Intravenous doripenem is a safe and well-tolerated treatment option for nosocomial infections.
  • Doripenem offers a favorable safety profile, including a low risk of seizures.
  • Doripenem can be administered via 1-hour or 4-hour infusion without increasing seizure risk.

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations

Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...

Dosage Interval and Administration Route: Determination Methods

A medication’s effectiveness largely depends on its appropriate dosage and the route of administration. Dosage ensures that a sufficient drug concentration is maintained in the bloodstream to elicit the desired therapeutic effect without causing toxicity. The route of administration affects the drug's bioavailability, rate of absorption, and onset of action, which are crucial for achieving optimal therapeutic outcomes. Drug dosage calculations are critical to tailoring therapy to individual...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
