Insights

Intravenous nicardipine effectively lowered blood pressure in children with severe hypertension. This study found nicardipine achieved significant blood pressure reduction, with most patients responding well.

Area of Science:

  • Pediatric critical care medicine
  • Cardiovascular pharmacology

Background:

  • Severe hypertension in children is a critical condition requiring prompt management.
  • Intravenous antihypertensive agents are often necessary for rapid blood pressure control in pediatric intensive care units.

Purpose of the Study:

  • To evaluate the efficacy and safety of intravenous nicardipine for treating severe hypertension in pediatric patients.
  • To determine the effectiveness of nicardipine as a single agent versus adjunctive therapy.

Main Methods:

  • Retrospective review of medical records for 29 children with severe hypertension treated with intravenous nicardipine.
  • Analysis of nicardipine dosage, blood pressure response, time to control, and adverse events.
  • Assessment of concurrent antihypertensive medications.

Main Results:

  • Intravenous nicardipine achieved a 16% reduction in systolic and a 23% reduction in diastolic blood pressure.
  • Blood pressure control was reached within an average of 2.7 hours.
  • Nicardipine was effective as a monotherapy in 84% of treatment instances.

Conclusions:

  • Intravenous nicardipine is an effective agent for lowering blood pressure in children with severe hypertension in an intensive care setting.
  • Close patient monitoring is crucial during nicardipine administration.
  • Further prospective studies are warranted to validate these findings.

Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Antihypertensive Drugs: Vasodilators

Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

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 Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

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...

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...
