Phenothiazines (Phenothiavnes)

Phenothiazines (Phenothiavnes): properties and applications

Phenothiazines (Phenothiavnes) are a group of chemically similar compounds that have different pharmacological properties. Some of them, such as chlorpromazine and trifluoperazine, are antipsychotic drugs; others, such as piperazine, are anthelmintics.

Phenothiazines were discovered in 1883 when German chemist Hermann Schultze synthesized the first of them, phenothiazine. Since then, more than 1,000 different compounds of this class have been synthesized, some of which are used in medicine.

The antipsychotic properties of phenothiazines were discovered in the 1950s. Since then, they have become widely used to treat various mental disorders such as schizophrenia and bipolar disorder. Some of the best-known antipsychotic drugs, such as chlorpromazine (Thorazine) and trifluoperazine (Stelazine), belong to the phenothiazine class.

The action of antipsychotic phenothiazines is associated with blocking dopamine receptors in the brain. This leads to a decrease in the activity of the dopamine system and an improvement in the symptoms of mental disorders. In addition, phenothiazines can also block other receptors in the brain, such as serotonin and α-adrenergic receptors.

Although effective, phenothiazines may cause unwanted side effects. Some of these include drowsiness, dry mouth, constipation, erectile dysfunction, digestive problems and changes in blood pressure. In addition, long-term use of antipsychotic phenothiazines can lead to the development of tardive dyskinesia, a movement disorder that may be irreversible.

In addition to their antipsychotic properties, phenothiazines are also used as anthelmintics. One of the most widely used anthelmintic phenothiazines is piperazine. It is used to treat infestations of certain types of roundworms.

In conclusion, phenothiazines are a group of chemically similar compounds that have different pharmacological properties. Some of these are antipsychotic drugs, which are widely used to treat mental disorders such as schizophrenia and bipolar disorder. However, they may cause unwanted side effects, so their use should be properly supervised and monitored by medical professionals. In addition, phenothiazines are also used as anthelmintics, but their use in this area also requires medical supervision and control.

Despite their shortcomings, phenothiazines remain an important class of drugs that help millions of people around the world suffering from mental disorders and helminth infestations. Further research and development in this area may lead to improvements in the efficacy and safety of phenothiazines and other drugs based on this class of compounds.

Phenothiazines are a group of chemically similar compounds that have different pharmacological properties. Some of them (eg, chlorpromazine and trifluoperazine) are antipsychotic drugs; others (such as piperazine) are anthelmintics. Phenothiazines have a tricyclic structure with a sulfur atom in the central ring. They inhibit dopamine receptors in the brain, which is responsible for their antipsychotic effect. The first member of this class was chlorpromazine, discovered in the 1950s. Since then, many phenothiazine derivatives have been synthesized with improved safety and efficacy profiles. Despite the emergence of new antipsychotics, phenothiazines are still widely used in psychiatric practice.

The phenothiazine group is a fairly large group of chemicals with various pharmacological and therapeutic properties. This group includes many different categories of chemical compounds, and in this article we will look at some of the most important members of this group and their effects on the human body.

Phenothiazines belong to the so-called neuroleptics, or antipsychotics. The term “neuroleptics” is traditionally used by doctors to refer to drugs that work in the central nervous system and have antihistamine, aminobiological,
