Rounding rituximab dose to nearest vial size
1Stanford Hosiptal and Clinics, Stanford, CA, USA. SaPatel@stanfordmed.org
Summary
Dose-rounding rituximab to the nearest vial size is feasible, with 99% of doses within 10% deviation. This practice offers significant financial savings and reduces drug wastage in cancer therapy.
Area of Science:
- Oncology
- Pharmacoeconomics
Background:
- Rituximab is a critical biologic therapy for hematologic and oncologic conditions.
- Accurate dosing is essential, but vial sizes can lead to discrepancies between prescribed and actual administered amounts.
- Optimizing drug utilization and cost-effectiveness is a key concern in cancer care.
Purpose of the Study:
- To assess the feasibility of dose-rounding rituximab to available vial sizes.
- To quantify the potential dose deviation resulting from rounding.
- To evaluate physician comfort and perceived financial impact of dose-rounding rituximab.
Main Methods:
- Retrospective chart review of 2028 rituximab orders over 24 months.
- Analysis of dose deviation when rounding to the nearest 100-mg vial.
- Physician survey on comfort levels with dose rounding and its financial implications.
Main Results:
- 99% of rituximab doses were within 10% deviation when rounded to the nearest 100-mg vial.
- 66.1% of doses were within 5% deviation.
- Physicians were comfortable with at least 5% deviation, projecting significant annual cost savings.
Conclusions:
- Dose-rounding rituximab to the nearest vial size is a feasible strategy.
- This approach leads to substantial financial savings for healthcare systems.
- Rounding reduces drug wastage and improves the economic efficiency of rituximab therapy.

01:15Determination 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...
01:19Dosage 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...
01:01Dosage Regimen: Fixed Dose
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

The development of extended-release formulations has facilitated the transition from intravenous to oral medication, offering a more convenient and patient-friendly approach to drug administration. This transition, however, requires careful management to ensure that therapeutic drug levels are maintained, preserving efficacy and avoiding adverse effects. Understanding pharmacokinetic principles and dosage calculations is critical during this process.Pharmacokinetics of the...
01:24Rational Dosage Regimen: Maintenance Dose and Loading Dose
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady state,...

01:25Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant
In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...
