Dosage Regimen: Fixed Dose01:01

Dosage Regimen: Fixed Dose

2.4K
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...

Rational Dosage Regimen: Maintenance Dose and Loading Dose

5.4K
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...

Drug Dosage Regimen: Overview

4.4K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

Drug Dosing: Infants and Children

283
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Drug Dosing: Geriatric Patients

232
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Drug Dosing: Obese Patients

254
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Area of Science:

  • Pediatric pharmacology
  • Medication safety

Background:

  • Accurate medication dosing is crucial for pediatric patient safety.
  • Parental medication administration errors are a significant concern.
  • Various drug delivery devices exist, with differing accuracy levels.

Purpose of the Study:

  • To quantify dosing errors in paracetamol syrup administration by parents.
  • To identify the most preferred drug delivery device.
  • To explore factors associated with accurate dosing.

Main Methods:

  • Observational study involving 386 parents of children aged 6-60 months.
  • Parents measured 5 ml paracetamol syrup using provided devices (spoon, syringe, cup).
  • Dose accuracy was verified using a calibrated glass cylinder; errors exceeded 10% variation.

Main Results:

  • 72 (18.65%) participants committed dosing errors (mild/moderate).
  • Measuring cups were the most preferred device (69.95%).
  • Syringe use was linked to significantly higher accuracy (3.57% error) versus spoons (56.25%) and cups (18.88%).

Conclusions:

  • Drug delivery device type is the primary factor influencing accurate pediatric medication dosing.
  • Dosing syringes offer superior accuracy compared to spoons and cups for paracetamol syrup.
  • Interventions promoting syringe use could reduce pediatric dosing errors.
