Prescription, Nonprescription and Orphan Drugs

Prescription, Nonprescription and Orphan Drugs

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Drug Toxicity: Dose-Dependent Reactions

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Drug Toxicity: Overview

Drug Toxicity: Overview

Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Desensitization and Tachyphylaxis

Desensitization and Tachyphylaxis

Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.
Several...

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical Poisoning: Potential Scenarios

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...

Pharmacovigilance

Pharmacovigilance

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...

Background:

Historically, radiation's harmful effects were recognized after initial exposure.
Current understanding of radiation risks and established safety protocols exist.
Significant increase in population radiation exposure due to medical imaging, particularly computed tomography (CT).

Purpose of the Study:

To address the rising medical radiation doses in the general population.
To examine the implications of overuse, overdose, and overdiagnosis associated with CT scans and screening.
To advocate for balanced radiation safety measures without inducing public fear.

Main Methods:

Review of historical radiation exposure data.
Analysis of current trends in medical imaging utilization, focusing on CT scans.
Assessment of risks associated with radiation overuse and overdiagnosis in screening contexts.

Main Results:

Computed tomography (CT) use has led to substantial increases in population radiation doses.
Inappropriate utilization contributes to overuse, overdose, and potential overdiagnosis, especially in screening applications.
A balance is needed to manage radiation risks without causing undue public apprehension.

Conclusions:

While radiation safety is understood, medical radiation, particularly CT, poses increasing population dose burdens.
Overuse and overdiagnosis are significant concerns that require careful management.
Preventing irrational fear of radiation is crucial to ensure continued access to beneficial medical procedures.
