Insights
Clonidine offers a favorable alternative to midazolam for pediatric premedication, showing fewer adverse effects on cognition and behavior. This review summarizes its use and compares it with benzodiazepines.
Area of Science:
- Anesthesiology
- Pediatric Pharmacology
Background:
- Midazolam is the most common pediatric premedication, but it has significant drawbacks.
- Limited trials validate midazolam's efficacy and safety.
- Clonidine use in pediatric premedication is increasing.
Purpose of the Study:
- To review clonidine's use in pediatric premedication.
- To compare clonidine with benzodiazepines for this indication.
- To present a clonidine premedication protocol.
Main Methods:
- Literature review of clonidine and benzodiazepine use in pediatric premedication.
- Summary of published trials comparing clonidine and benzodiazepines.
- Analysis of perioperative effects and adverse events.
Main Results:
- Clonidine enhances perioperative management in children with mild circulatory effects.
- Clonidine is associated with fewer adverse effects than midazolam.
- Trials comparing clonidine and midazolam are limited but growing.
Conclusions:
- Clonidine is a viable alternative to midazolam, lacking its negative effects on cognition and behavior.
- Clonidine offers beneficial perioperative effects.
- Clinical experience replacing midazolam with clonidine in children has been positive.
Purpose Of Review:
The aim of this review is to summarize the use of clonidine for paediatric premedication and to make a comparison with benzodiazepines. A routine clonidine premedication protocol is also presented.
Recent Findings:
In the US 50% of young children undergoing surgery receive premedication and midazolam is the most frequently used drug. The number of trials that compare midazolam with active controls are few and this premedicant is not adequately validated. Clonidine is still used as premedication in a small number of centres but the literature on paediatric use of clonidine is steadily growing. A recent review article has concluded that the use of clonidine does enhance the quality of perioperative management in infants and children and more recent publications support the use of clonidine for premedication. Its effect on the circulation is mild but routine atropine administration is recommended. Contraindications to the use of clonidine are few. Apart from a general overview on the effects of clonidine this article will also summarise the published trials that have compared clonidine with benzodiazepines for premedication in children.
Summary:
Midazolam the most commonly used drug for paediatric premedication worldwide. Despite having a number of beneficial effects it is far from an ideal premedicant, especially concerning its effect on cognition/amnesia, confusion and long-term behavioural disturbances. Clonidine lacks the majority of the negative effects associated with midazolam and is associated with a number of beneficial perioperative effects. Our clinical experience of replacing midazolam with clonidine as premedicant in children, including also outpatients, has been favourable.

Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
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...

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
Anxiolytic Drugs: Overview
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic circuitry.
