Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

614
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Enhanced Elimination of Poison01:26

Enhanced Elimination of Poison

563
Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
Renal excretion is the...

Pharmacovigilance01:19

Pharmacovigilance

951
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Factors Affecting Renal Clearance: Drug Distribution and Drug Interactions

204
Renal clearance plays a pivotal role in drug elimination from the body and can be influenced by drug distribution and interactions. Understanding these factors is crucial in pharmacology as they impact the effectiveness and duration of drug therapy.
One important factor is the relationship between renal clearance and the apparent volume of distribution. Renal clearance tends to be inversely proportional to the apparent volume of distribution. Drugs with an extensive distribution volume or those...

Pharmacokinetics: Overview01:10

Pharmacokinetics: Overview

6.7K
Pharmacokinetics is a scientific discipline that focuses on the journey of a drug within the body, encompassing four key stages: absorption, distribution, metabolism, and elimination. The first stage, absorption, involves the drug's transfer into the bloodstream. Several factors dictate the extent and speed of this process. For example, the liver often metabolizes oral drugs before they reach systemic circulation, leading to only partial absorption. In contrast, intravenous (IV)...

Pharmacodynamics: Overview and Principles

1.5K
Pharmacodynamics is a scientific field that delves into drugs' intricate biochemical, cellular, and physiological effects on the human body. The study of pharmacodynamics helps us understand how drugs interact with the body and elicit various responses.
Most drugs' effects result from their interactions with drug receptors or targets within the body. These interactions trigger specific responses at the cellular or systemic level. Drug receptors can be found on the surfaces of cells or...

Area of Science:

  • Environmental Science
  • Pharmaceutical Science
  • Public Health

Background:

  • Improper medication disposal poses significant environmental risks, impacting biological ecosystems.
  • Pharmacists play a critical role in educating the public on safe medication disposal methods.

Purpose of the Study:

  • To assess pharmacists' knowledge, perceptions, and practices concerning medication disposal in Trinidad.
  • To identify gaps in current practices and inform targeted interventions.

Main Methods:

  • A cross-sectional electronic survey was administered to pharmacists in Trinidad.
  • Data on demographics, knowledge, perception, and practice of medication disposal were collected and analyzed.
  • Chi-squared tests were used to find associations between demographics and responses.

Main Results:

  • A majority of pharmacists believed improper disposal harms the environment, but less than half recognized the link to antimicrobial resistance.
  • While most returned expired drugs appropriately, a significant portion disposed of them in workplace garbage.
  • Many pharmacists did not counsel patients on disposal and were hesitant to recommend flushing medications, except for narcotics.

Conclusions:

  • Pharmacists require further education on best practices for medication disposal, including environmental impacts and antimicrobial resistance.
  • Public awareness campaigns are necessary to promote safe medication disposal and reduce environmental contamination.
  • Targeted interventions are needed to improve pharmacist practices and patient counseling on medication disposal.
