Routes of Drug Administration: Parenteral01:25

Routes of Drug Administration: Parenteral

3.8K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

Routes of Drug Administration: Overview

11.4K
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

2.6K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Dosage Regimens: Designs and Approaches01:28

Dosage Regimens: Designs and Approaches

477
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...

Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

357
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...

Pharmaceutical Poisoning: Potential Scenarios01:26

Pharmaceutical Poisoning: Potential Scenarios

80
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

    Area of Science:

    • Ophthalmology
    • Patient Education
    • Medication Adherence

    Background:

    • Difficulties with eye drop application can lead to poor patient compliance with prescribed therapies.
    • Effective medication delivery is crucial for successful treatment outcomes in various ocular conditions.

    Purpose of the Study:

    • To evaluate the effectiveness of a novel technique for teaching patients self-administration of eye drops.
    • To compare the reliability of patient-administered drops using the new technique versus drops administered by a home caregiver.

    Main Methods:

    • A cohort of patients was taught a specific hand-steadying and visual observation technique for eye drop application.
    • Performance in drop delivery was compared between the group trained in the technique and a control group receiving caregiver assistance.

    Main Results:

    • Patients trained in the technique demonstrated reliability in drop delivery comparable to those receiving caregiver assistance.
    • The technique was found to enable effective and safe delivery of eye drops for most patients.

    Conclusions:

    • A structured teaching approach for eye drop administration can significantly improve patient compliance and self-efficacy.
    • This technique offers a viable alternative for patients who have difficulties with standard drop application methods, promoting independence in treatment.
