Diazepam (Valium) | 10mg
Diazepam, first marketed as Valium, is a medicine of the benzodiazepine family that acts as an anxiolytic. It is commonly used to treat a range of conditions, including anxiety, seizures, alcohol withdrawal syndrome, benzodiazepine withdrawal syndrome, muscle spasms, insomnia, and restless legs syndrome. It may also be used to cause memory loss during certain medical procedures. It can be taken by mouth, inserted into the rectum, injected into muscle, injected into a vein or used as a nasal spray. When given into a vein, effects begin in one to five minutes and last up to an hour. By mouth, effects begin after 15 to 60 minutes.
Common side effects include sleepiness and trouble with coordination. Serious side effects are rare. They include suicide, decreased breathing, and an increased risk of seizures if used too frequently in those with epilepsy. Occasionally, excitement or agitation may occur. Long-term use can result in tolerance, dependence, and withdrawal symptoms on dose reduction. Abrupt stopping after long-term use can be potentially dangerous. After stopping, cognitive problems may persist for six months or longer. It is not recommended during pregnancy or breastfeeding. Its mechanism of action works by increasing the effect of the neurotransmitter gamma-aminobutyric acid (GABA).
Diazepam was patented in 1959 by Hoffmann-La Roche. It has been one of the most frequently prescribed medications in the world since its launch in 1963.[9] In the United States it was the best-selling medication between 1968 and 1982, selling more than 2 billion tablets in 1978 alone. In 2019, it was the 117th most commonly prescribed medication in the United States, with more than 5 million prescriptions. In 1985 the patent ended, and there are now more than 500 brands available on the market.
Medical uses
Diazepam tablets (10, 5, and 2 mg)
Diazepam is mainly used to treat anxiety, insomnia, panic attacks and symptoms of acute alcohol withdrawal. It is also used as a premedication for inducing sedation, anxiolysis, or amnesia before certain medical procedures (e.g., endoscopy). In 2020, it was approved for use in the United States as a nasal spray to interrupt seizure activity in people with epilepsy. Diazepam is the most commonly used benzodiazepine for “tapering” benzodiazepine dependence due to the drug’s comparatively long half-life, allowing for more efficient dose reduction. Benzodiazepines have a relatively low toxicity in overdose.
Diazepam has a number of uses including:
- Treatment of anxiety, panic attacks, and states of agitation
- Treatment of neurovegetative symptoms associated with vertigo
- Treatment of the symptoms of alcohol, opiate, and benzodiazepine withdrawal
- Short-term treatment of insomnia
- Treatment of muscle spasms
- Treatment of tetanus, together with other measures of intensive treatment
- Adjunctive treatment of spastic muscular paresis (paraplegia/tetraplegia) caused by cerebral or spinal cord conditions such as stroke, multiple sclerosis, or spinal cord injury (long-term treatment is coupled with other rehabilitative measures)
- Palliative treatment of stiff person syndrome
- Pre- or postoperative sedation, anxiolysis or amnesia (e.g., before endoscopic or surgical procedures)
- Treatment of complications with stimulant overdoses and psychosis, such as cocaine or methamphetamine
Used in treatment of organophosphate poisoning and reduces the risk of seizure induced brain and cardiac damage.
- Preventive treatment of oxygen toxicity during hyperbaric oxygen therapy
Dosages should be determined on an individual basis, depending on the condition being treated, severity of symptoms, patient body weight, and any other conditions the person may have.
Seizure
Intravenous diazepam or lorazepam are first-line treatments for status epilepticus.However, intravenous lorazepam has advantages over intravenous diazepam, including a higher rate of terminating seizures and a more prolonged anticonvulsant effect. Diazepam gel was better than placebo gel in reducing the risk of non-cessation of seizures. Diazepam is rarely used for the long-term treatment of epilepsy because tolerance to its anticonvulsant effects usually develops within six to 12 months of treatment, effectively rendering it useless for that purpose.
The anticonvulsant effects of diazepam can help in the treatment of seizures due to a drug overdose or chemical toxicity as a result of exposure to sarin, VX, or soman (or other organophosphate poisons), lindane, chloroquine, physostigmine, or pyrethroids.
Diazepam is sometimes used intermittently for the prevention of febrile seizures that may occur in children under five years of age. Recurrence rates are reduced, but side effects are common so the decision to treat febrile seizures (which are benign in nature) with medication should use this as part of the evaluation. Long-term use of diazepam for the management of epilepsy is not recommended; however, a subgroup of individuals with treatment-resistant epilepsy benefit from long-term benzodiazepines, and for such individuals, clorazepate has been recommended due to its slower onset of tolerance to the anticonvulsant effects.
