Classification of additional groups
In the study of pharmacology, precise classification of medicinal substances holds a special place. The topic "Antiseptic and Disinfectant Agents" is fundamental for understanding the principles of disinfection. In addition to the main, traditional chemical classes, modern nomenclature necessarily distinguishes so-called additional groups of antiseptics.
This division is critically necessary for the proper systematization of the huge pool of medicinal substances. According to the presented classification, these additional agents are globally divided into two large and fundamentally different categories:
- Antiseptics from mixed and other groups, which are synthetic compounds.
- Herbal preparations, which differ in their source, as they are obtained exclusively from natural raw materials.
Understanding this structure helps students and doctors easily navigate the variety of trade and international nonproprietary names.
Synthetic drugs of mixed structure
The group of synthetic antiseptics belonging to mixed and other groups unites drugs that have completely different chemical structures. This category includes many well-known agents widely used in everyday medical practice.
Among the prominent representatives of synthetic compounds, the following are distinguished:
- Ambazone monohydrate is a synthetic substance widely known in pharmacy chains under the trade name Pharyngosept.
- Benzydamine is the active ingredient of the popular drug Tantum Verde.
- Hexetidine is the chemical basis of the medicinal product Hexoral.
- Picloxydine is the active component available under the name VitBACT.
In addition to single-component drugs (containing a single active substance), the classification includes combined agents in this same additional group. A striking example of such a multi-component drug is Strepsils.
Also adjacent to this broad category are specific antibacterial drugs, namely topical antibiotics. The only example of such a topical antibiotic mentioned in this section of the classification is gramicidin.
Herbal preparations
The second major additional group in the classification consists of antiseptics of exclusively herbal origin. The fundamental difference between this group and the previous one is that all preparations here are based on medicinal plant extracts.
When answering test questions, it is important to clearly understand the nature of these agents. Their source is precisely plant extracts. They are fundamentally not produced on the basis of microbiological synthesis products, are not mined from mineral raw materials, and are not synthetic compounds.
The arsenal of herbal antiseptics includes the following key drugs and sources of natural raw materials:
- Calendula flowers are used as an independent plant material to obtain effective antiseptic agents.
- Eucalyptus preparations — this subgroup includes both eucalyptus leaves in their pure form and finished pharmaceutical forms based on them. The latter include such well-known drugs as Chlorophyllipt and Eucalimin.
- St. John's wort preparations — a classical representative of medicinal products from this plant is Novoimanin.
- Sanguirythrine is another important drug obtained by extraction from plant raw materials.
Briefly: answers to topical questions
From which plant raw material is the drug sanguirythrine obtained?
The drug sanguirythrine is obtained from Macleaya plant raw material. Macleaya cordata and Macleaya microcarpa are used as the source for isolating the sum of alkaloid bisulfates (sanguinarine and chelerythrine). This herbal preparation is effective in diseases of mixed etiology, including pyinflammatory and fungal lesions. Its spectrum of antimicrobial activity covers gram-positive and gram-negative bacteria, as well as fungi, including the genus Candida and dermatophytes.
Which combined drugs belong to the additional group of antiseptics?
Combined agents are directly classified in sources under the additional group of antiseptics, an example being Strepsils. It contains dichlorobenzyl alcohol and amylmetacresol, exerts an antiseptic effect on gram-positive and gram-negative flora, and also relieves pain and soothes irritation.
What is the spectrum of antimicrobial action of chlorophyllipt?
Chlorophyllipt possesses antibacterial activity. Sources specifically indicate its specific activity in staphylococcal intestinal infections. The drug is also indicated for use in cholecystitis and pyelonephritis. Additionally, chlorophyllipt stimulates regenerative processes.
What is the mechanism of action of benzydamine?
Sources do not describe the molecular mechanism of action of benzydamine, but indicate its pharmacological triad of action. The drug produces the following effects:
- Antiseptic action.
- Anti-inflammatory action.
- Local anesthetic action.
The spectrum of activity of benzydamine includes bacteria (including Gardnerella vaginalis), fungi, and Trichomonas. It is used in dentistry, ENT practice, and gynecology.
For quick memorization of the main herbal antiseptics, use the acronym CESP: Calendula, Eucalyptus, St. John's wort, Sanguirythrine.
Class and exam questions
What exactly are herbal preparations based on within the antiseptic group?
These preparations are based strictly on medicinal plant extracts. As emphasized in the classification, they are not produced from mineral raw materials, synthetic compounds, or products of microbiological synthesis.
To which classification group does the drug Strepsils belong?
Strepsils is classified as a combined agent. In general systematics, it is part of the additional (mixed and other) groups of antiseptics.
Is gramicidin a standard antiseptic agent?
No, gramicidin is singled out in the classification separately as a topical antibiotic. However, in educational literature, it is reviewed together with additional groups of antiseptic agents.
What trade names correspond to substances such as ambazone, benzydamine, and hexetidine?
Ambazone monohydrate is available under the name Pharyngosept, benzydamine is known as Tantum Verde, and hexetidine is the basis of the drug Hexoral.
