Abstract

Insights

Ondansetron combined with cisplatin increases nephrotoxicity risk more than tropisetron. Tropisetron is a safer alternative for patients undergoing cisplatin chemotherapy, showing milder kidney function effects.

Area of Science:

  • Nephrology
  • Oncology
  • Pharmacology

Background:

  • 5-HT3 receptor antagonists, like ondansetron, may cause nephrotoxicity with cisplatin.
  • Limited data exists on these effects in human patients.
  • This study investigates the impact of 5-HT3 receptor antagonists on cisplatin-induced nephrotoxicity.

Purpose of the Study:

  • To determine if 5-HT3 receptor antagonists enhance or aggravate cisplatin-induced nephrotoxicity in patients.
  • To compare the nephrotoxic effects of ondansetron, tropisetron, and ramosetron when used with cisplatin.

Main Methods:

  • Retrospective review of 600 tumor patients receiving cisplatin (≥60 mg/m²) chemotherapy.
  • Analysis of patients treated with cisplatin combined with ondansetron, tropisetron, or ramosetron (200 cases each).
  • Evaluation of cisplatin dosage, baseline creatinine clearance, and risk factors in a multivariable model.

Main Results:

  • Higher incidence of Grade ≥2 serum creatinine elevation in the cisplatin + ondansetron group compared to cisplatin + tropisetron (P=0.04).
  • No significant difference in nephrotoxicity between cisplatin + ondansetron and cisplatin + ramosetron groups (P=0.3).
  • Cisplatin dosage and tumor type identified as independent risk factors for nephrotoxicity.

Conclusions:

  • Higher cisplatin dosage and regular ondansetron use increase nephrotoxicity risk.
  • Tropisetron demonstrates a milder effect on kidney function, making it a preferable alternative.
  • Findings suggest careful selection of 5-HT3 receptor antagonists during cisplatin chemotherapy is crucial.

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Drug-Receptor Interaction: Antagonist01:28

Drug-Receptor Interaction: Antagonist

An antagonist is a drug that binds strongly to a receptor without activating it. An antagonist prevents other molecules, such as neurotransmitters or hormones, from binding to the receptor and triggering a cellular response. Such interaction effectively hinders the normal physiological processes mediated by the receptor, resulting in various pharmacological effects depending on the specific receptor targeted.
Antagonists can be classified as competitive or noncompetitive based on their...

Antiasthma Drugs: Muscarinic Receptor Antagonists

Muscarinic receptor antagonists, also known as antimuscarinic agents, are a class of bronchodilators used to treat asthma, although they are more commonly used to treat COPD. They work by inhibiting the action of acetylcholine (ACh), a neurotransmitter, on muscarinic receptors found in the airways.
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...

Adrenergic Antagonists: ɑ and β-Receptor Blockers

Third-generation β-blockers, such as labetalol and carvedilol, represent a significant advancement in managing cardiovascular conditions. Unlike conventional β-blockers, which can induce peripheral vasoconstriction, third-generation drugs block α1 adrenoceptors. This promotes vasodilation through several mechanisms, such as increased nitric oxide production, inhibition of calcium ion entry, opening of potassium ion channels, and antioxidant action. Labetalol, for instance, is...

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists01:28

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists

Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...

Adrenergic Antagonists: Pharmacological Actions of ɑ-Receptor Blockers

α-Adrenergic antagonists, known as α-blockers, exert their effects by inhibiting α-adrenoceptors, leading to specific physiological actions. α1-blockers and α2-blockers have distinct pharmacological actions and therapeutic applications.
α1-blockers: These drugs inhibit α1-adrenoceptors on smooth muscle cells, resulting in vasodilation. This vasodilation lowers blood pressure, making α1-blockers valuable in treating hypertension. Additionally,...
