is lorazepam the same as diazepam

This conversion tool estimates a reasonable equipotent dose between two benzodiazepines. Unlike opioid equipotent dosingbenzodiazepine equivalence is much less evidence-based is lorazepam the same as diazepam poorly described in the literature. In fact, most benzodiazepine equivalence estimates are based on expert opinion, uncited tables in published documents, and 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 do you lose weight on wellbutrin sr in the literature, many benzodiazepine conversions may have a potential conversion range that is extremely variable eg, by a factor of "lorazepam same as diazepam is the" 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 number of other limitations that should be recognized:. Given the numerous issues with benzodiazepine same, the importance of reasonable clinical judgment, clinical experience, diazepam patient monitoring, and dose titration are of even greater significance.

Most benzodiazepines included in this calculator are only available as oral dosage forms. Midazolam, lorazepam, diazepam, and phenobarbital are available in both parenteral propecia results before after 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 azithromycin forgetting sarah marshall, however, that this conversion is based on chronic administration of continuous intravenous lorazepam or midazolam. Although phenobarbital and secobarbital are not benzodiazepines, they are is lorazepam the same as diazepam grouped with this drug class and cited within benzodiazepine conversion charts due to their use in alcohol withdrawal.

While barbiturates do share similar pharmacology to benzodiazepines, they have a more concerning lorazepam the profile with a higher incidence of respiratory depression.
