Insights

Therapeutic doses of clarithromycin can cause hypersomnia in children, a previously unreported side effect. This sleepiness resolved after discontinuing the antibiotic, suggesting a causal link.

Area of Science:

  • Pediatric Pharmacology
  • Neuroscience
  • Clinical Toxicology

Background:

  • Clarithromycin is a widely used macrolide antibiotic in pediatric populations.
  • Adverse drug reactions (ADRs) can significantly impact treatment adherence and patient outcomes.
  • Understanding rare ADRs is crucial for comprehensive pediatric pharmacovigilance.

Observation:

  • Two pediatric cases of hypersomnia are presented following oral clarithromycin monotherapy.
  • A 4-year-old girl experienced deep sleep after each dose, while a 13-year-old boy reported increased daytime sleepiness and prolonged nighttime sleep.
  • Symptoms resolved upon cessation of clarithromycin, with no other causative factors identified.

Findings:

  • The cases strongly suggest clarithromycin-induced hypersomnia in children, a novel finding in pediatric medicine.
  • Naranjo's Adverse Drug Reaction Probability Scale scores supported the diagnosis in both patients.
  • The temporal relationship between clarithromycin intake, symptom onset, and resolution is a key indicator.

Implications:

  • Pediatricians and clinicians should consider hypersomnia as a potential uncommon adverse reaction to clarithromycin.
  • Increased awareness can lead to earlier diagnosis and management of such reactions.
  • This highlights the importance of monitoring for behavioral changes during antibiotic therapy in children.

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
Management of Insomnia01:19

Management of Insomnia

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

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...

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...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
CNS Depressants: Barbiturates and Benzodiazepines01:14

CNS 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...
