A Novel Approach for the Administration of Medications and Fluids in Emergency Scenarios and Settings
Published on: November 9, 2016
Resumen
La interrupción abrupta de la terapia con clonidina no causó un exceso de presión arterial en los pacientes. Sin embargo, algunos experimentaron síntomas de abstinencia como aprehensión e insomnio, que se resolvieron al reiniciar la clonidina.
Área de la Ciencia:
- Cardiología Cardiología.
- Farmacología Farmacología.
Sus antecedentes:
- La clonidina es un medicamento comúnmente utilizado para controlar la hipertensión.
- El cese repentino de la terapia con clonidina puede conducir potencialmente a efectos adversos.
Objetivo del estudio:
- Para investigar los efectos de la abrupta retirada de clonidina en la presión arterial.
- Para evaluar la incidencia de los síntomas de abstinencia durante la interrupción de la clonidina.
Principales métodos:
- Un estudio prospectivo en el que participaron siete pacientes sometidos a una abrupta interrupción del tratamiento con clonidina.
- Monitoreo de la presión arterial cada hora o cada dos horas durante el período de abstinencia.
- La reinstauración de la terapia con clonidina 36 o 48 horas después de la interrupción.
Principales resultados:
- La presión arterial volvió a los niveles previos al tratamiento sin un fenómeno significativo de "sobrepaso".
- Dos pacientes experimentaron síntomas de abstinencia que incluían aprehensión, insomnio, palpitaciones y sudoración.
- La reinstauración de la clonidina alivió eficazmente estos síntomas adversos.
Conclusiones:
- La interrupción abrupta de la terapia con clonidina en esta cohorte no resultó en un exceso de presión arterial.
- Los síntomas de abstinencia pueden ocurrir, pero son manejables con la pronta reinstalación de la clonidina.

01:20Desensitization 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.

01:15Antihypertensive Drugs: Thiazide-Class Diuretics
Thiazide diuretics are sulfonamide derivatives featuring a benzothiadiazine ring system in their molecular structure. Based on this structure, thiazide diuretics can be categorized into two groups: thiazide-type and thiazide-like diuretics. Thiazide-type diuretics, including hydrochlorothiazide and chlorothiazide, consist of a benzothiadiazine backbone with an attached sulfonamide group. Thiazide-like diuretics, such as chlorthalidone and indapamide, lack the thiazide ring but demonstrate...
01:14CNS Depressants: Barbiturates and Benzodiazepines
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...
01:28IV Infusion to Oral Dosing: Conversion Methods
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...
01:30Toxidromes: Clinical Features
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...
01:30Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
