equivalent doses midazolam lorazepam
This conversion tool estimates a reasonable equipotent dose between two benzodiazepines. Unlike opioid equipotent lorazepam doses equivalent midazolambenzodiazepine equivalence is much less evidence-based and poorly described in the literature. In fact, most benzodiazepine equivalence estimates are based on expert opinion, uncited tables in published documents, taking a xanax bar everyday clinical practice.
All benzodiazepine conversions used in this calculator are based on published equipotent dose estimates. The following guiding principles govern the calculator's logic:. Due to discrepancies in the literature, many benzodiazepine conversions may have a potential conversion range that is extremely variable eg, by a factor of 10x or greater. These wide ranges of confidence highlight the lack of firm, evidence-based literature supporting specific conversion ratios.
In addition to an overall lack of evidence to support specific conversions, there are a midazolam equivalent lorazepam doses of other limitations that should be recognized:. Given the numerous issues with benzodiazepine equivalence, the importance of reasonable clinical judgment, clinical experience, appropriate patient monitoring, and dose titration are of even greater significance.
Most benzodiazepines included in this calculator are only what is klonopin used for and does it work as oral dosage forms. Midazolam, lorazepam, diazepam, and phenobarbital are available in "equivalent lorazepam doses midazolam" parenteral and oral formulations.
Because published benzodiazepine dose conversions are based on oral administration, parenteral formulations may not use the same conversion ratio. The following bioavailabilities are available based on published literature. Note how the large variances in oral bioavailability highlight the significant inter-patient variability:. Unlike nearly all other benzodiazepine conversions, the conversion between intravenous midazolam and lorazepam has been well studied in mechanically ventilated patients.
It should be noted, however, that this conversion is based on chronic administration of continuous intravenous lorazepam or midazolam. Although phenobarbital and secobarbital are not benzodiazepines, they are commonly grouped with this drug class lorazepam doses cited within benzodiazepine conversion charts due to their use in alcohol withdrawal. While replacing methadone with tramadol 50mg high do share similar pharmacology to benzodiazepines, they have a more concerning safety profile with a higher incidence of respiratory depression.
