Insights

Enteric-coated mycophenolate sodium (EC-MPS) offers no significant gastrointestinal (GI) benefit over mycophenolate mofetil (MMF) in transplant patients. Both immunosuppressants demonstrate similar efficacy and safety profiles.

Area of Science:

  • Immunology
  • Pharmacology
  • Transplantation Medicine

Background:

  • Mycophenolate mofetil (MMF) has been widely used for over a decade.
  • Enteric-coated mycophenolate sodium (EC-MPS) was developed as an alternative to MMF.
  • EC-MPS aims to reduce upper gastrointestinal (GI) side effects by releasing mycophenolic acid (MPA) in the small intestine, unlike MMF which absorbs in the stomach.

Purpose of the Study:

  • To review the pharmacology, pharmacokinetics, and clinical trial data comparing EC-MPS and MMF.
  • To evaluate the efficacy, safety, and GI tolerability of EC-MPS versus MMF in solid-organ transplantation.

Main Methods:

  • Review of three randomized, controlled clinical trials comparing MMF and EC-MPS.
  • Analysis of pharmacological and pharmacokinetic data for both agents.

Main Results:

  • EC-MPS demonstrated similar efficacy and safety compared to MMF.
  • No significant improvement in GI side effects was observed with EC-MPS.
  • Bioequivalence dosing for EC-MPS was only established when co-administered with cyclosporine.

Conclusions:

  • EC-MPS is a safe and effective immunosuppressant for preventing acute rejection in renal transplantation.
  • The anticipated reduction in GI side effects with EC-MPS was not realized.
  • Further pharmacokinetic studies are needed for EC-MPS.

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase

Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...

Drug toxicity: Drug–Drug Interaction

Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...

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...
Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
