Single doses usually range from 0.5–3 mg and result in peak levels of 8–37 ng/ml. Alprazolam has an intermediate onset of action (function of rate of absorption) compared to other Oxford House BZDs and mean plasma elimination half-life of ~6–15 h 169, 170. In a phase 1 study, 1 mg of inhaled alprazolam reached a peak concentration of 48 ng/ml in smokers and 26.72 ng/ml in non-smokers after 1.8 min 171. It is mainly metabolized by CYP3A4, which means that pharmacological interactions must be considered. The two main metabolites of alprazolam are 4-hydroxyalprazolam and α-hydroxyalprazolam, both of which have low plasma concentrations in comparison to alprazolam and do not contribute to the pharmacological effects of this drug.
- Due to a large surface area, and high permeability and blood flow in the lung, rapid systemic drug effects are possible with inhalation therapies 164.
- Common medications include diazepam, alprazolam, lorazepam, clonazepam, oxazepam, nitrazepam, temazepam, and chlordiazepoxide.
Understanding Dihydrocodeine Addiction
- Symptoms originally treated by the drug—such as anxiety, insomnia, or seizures—return with greater intensity due to GABA receptor dysfunction in the brain and nervous system.
- There was no evidence of amitriptyline toxicity, as the patient did not show sedation, anticholinergic effects, arterial hypotension, or cardiac arrhythmias.
- The seizure begins with a tonic posture of the left hand and abduction of the left arm flexed at the elbow.
- Patients on maintenance therapy may eventually reach a period of stability in which withdrawal to a lower dose or abstinence may be considered.
- At a cellular level, benzodiazepines work by enhancing the efficacy of GABA, a neurotransmitter responsible for inhibiting brain activity.
Regular benzodiazepine use can lead to tolerance and physical dependence. As the brain adapts to the medication, GABA receptor sensitivity decreases, requiring higher doses to maintain the same sedative, anxiolytic, or hypnotic effect. Over time, the risk of developing benzodiazepine use disorder rises, particularly when used without physician oversight or combined with other substances. These symptoms may still be uncomfortable or disruptive to someone’s life, but they will continue to improve so long as someone stays away from using benzos. Additional care in the form of psychiatric care or clinical therapy can help support and accelerate the recovery process. Depression and anxiety will typically resolve in time, but there have been instances of certain cognitive deficits such as memory problems lasting for many years, or even indefinitely.
More About Benzodiazepine Addiction
Someone’s age at the time of benzodiazepine use and addiction has a very large impact on the severity of their withdrawal symptoms as well as the duration and possibility of a full recovery. It has been documented that elderly people suffer much greater cognitive deficits benzo withdrawal seizure during and after benzo withdrawal. In addition, they typically recover more slowly, and the degree to which they recover is often not as complete as it is in younger benzo addicts. That being said, someone who becomes addicted to benzos at a younger age will frequently have poorer outcomes with regard to treatment and relapse into chronic benzo use. There is a wide range of factors that can contribute to the intensity of benzo withdrawal.

There are also those who never fully recover, and suffer from cognitive and emotional problems for the rest of their lives. There are a few specific factors that can contribute to both the intensity and duration of benzo withdrawal symptoms. Benzodiazepine withdrawal requires medically supervised drug detox to help keep withdrawal symptoms manageable and allows doctors to act quickly if potentially fatal symptoms, such as seizures, occur. The Ashton Manual is a widely recognized resource for benzodiazepine withdrawal. It was created by Professor Heather Ashton, a leading expert in the field of benzodiazepine withdrawal. The manual provides detailed information on the tapering process, which involves gradually reducing the dosage of benzodiazepines over a period https://www.adost.co.kr/archives/12133 of time to minimize withdrawal symptoms.
