Pharmacological action of Valium
The active substance of Valium, diazepam, has a pronounced sedative, muscle relaxant, hypnotic and anticonvulsant effect. During therapy, blood vessels dilate, resulting in a decrease in blood pressure. The drug is effective for the treatment of convulsive paroxysms associated with epilepsy, obsessive and phobic disorders, and sleep disorders.
The medication is used orally, intravenously and intramuscularly, with a sedative effect developing most quickly after intravenous administration (within a few minutes). According to the instructions, Valium has a stable therapeutic effect after 2-7 days of use. When using the medication against the background of withdrawal syndrome that develops with chronic alcoholism, the medication helps get rid of hallucinations and reduce the severity of other symptoms - tremor, agitation and delirium.

Does methadone help treat heroin addiction?
Since methadone is officially prohibited in Russia and is included in the list of narcotic substances, we do not have programs in our country to combat heroin addiction using methadone. But it has quite extensive use in countries such as: Thailand, the Netherlands, Great Britain, Sweden, Canada and Australia. Methadone is included in special anti-drug programs there. Earlier, in the 60s of the last century, doctors in the United States of America were pioneers in the use of methadone in the fight against drug addiction.
In our country, the topic of using methadone within the framework of government programs is quite actively discussed, but there is no consensus yet. Various specialized UN committees and the World Health Organization have repeatedly called on Russia to start using this drug in the fight against drug addiction. This method has not yet been tested in our country. The main argument here is the fact that replacing one powerful drug with another, even stronger one, will be a mistake.
However, the methadone program is already being phased out in the United States, and clear positive results from methadone therapy have been noted only in Sweden. Moreover, one cannot help but note the fact that, for example, in the United States, there are more deaths from methadone overdose than cocaine and heroin combined. Opponents of methadone therapy describe its promotion as a drug as drug propaganda.
Here are a few reasons why methadone programs are not accepted in Russia:
- Methadone is cheaper and easier to produce than heroin
- Treating addiction to methadone is much more difficult and takes longer than to treat any other opiate.
- Methadone use is even more harmful to the body than heroin use.
- The dose of methadone must be strictly regulated by doctors, since exceeding it will almost certainly threaten the patient with death. Due to the ability of methadone to accumulate in body tissues, the dose will quickly increase, and the intervals between doses will inevitably decrease
