Benzodiazepine equivalency table pdf


Which benzo has the longest half life?

The various benzodiazepines are listed in order of the shortest acting to the longest acting (by the approximate elimination half-life of the drug), however this time may greatly vary between persons. triazolam (Halcion®) – 2 hours midazolam (Versed®, Hypnovel®) – 3 hours (1.8-6 hours) oxazepam (Serax®) – 4-15 hours

What is the drug classification of benzodiazepines?

In addition to being classified as a controlled substance, benzodiazepines also have a pharmacokinetic classification, based on how long the drug is active in the body. There are three main classifications: long-acting, intermediate-acting, and short-acting. Each benzodiazepines classification impacts why that drug is prescribed.

Can clonidine test positive for benzodiazepines?

^This. Clonidine is completely unrelated to benzodiazepines in any way. It works mainly by decreasing the levels of norepinephrine, benzos are GABAergic. However, if you are taking a longer acting benzo, it could remain in your system even the days you aren’t taking it if you plan on alternating, and as a result physical dependence could form.

Can benzodiazepines used IV?

How can I make benzodiazepines more effective?

The key to effective and safe long-term use of benzodiazepines is: the careful selection of patients who might benefit from them; administration in clinical situations in which they are more likely to be beneficial; use of lower doses and in conjunction with an antidepressant, if possible; monitoring and managing their …

Is benzodiazepine conversion single or multiple dose?

In addition to an overall lack of evidence to support specific conversions, there are a number of other limitations that should be recognized: Varying durations of action – Due to differences in half-life, active metabolites, and drug accumulation, benzodiazepine conversions should account for single-dose versus multiple-dose situations.

Do parenteral formulations have the same conversion ratio?

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:

Is phenobarbital a benzodiazepine?

Although phenobarbital and se cobarbital are not benzodiazepines, they are commonly grouped with this drug class and cited within benzodiazepine conversion charts due to their use in alcohol withdrawal.
