The present invention also relates to the process of preparing the already above mentioned pharmaceutical preparations. According to the International Patent Classification (IPC), the present invention belongs to the class: A 6 IK (9/06, 9/08, 9/66, 9/10, 9/12, 36/20) A 61P 31/00.
Background Art
Numerous scientific investigations have shown that medicinal plants contain biologically active classes of compounds (polyphenols, flavonoids, tannins, essential oils, mucus etc.) with different pharmacological activities and a real therapeutic actions ascribed. Due to the current trend of "way back to nature and its resources", application of medicinal plants as raw materials in pharmaceutical industry (herbal drugs), cosmetic industry (medicinal cosmetics) and food industry (dietetic supplements, functional foods) becomes important and a matter of interest.
Rational phytotherapy, based on the scientific basis and the application of high-quality, well defined, efficient and safe herbal remedies, have been assuming an increasingly important place in the modern pharmacotherapy. Herbal preparations are gaining increasing importance in the prophylaxis and various diseases treatment, and, compared to synthetic medicines, with the main advantage in well-documented evidences on less of adverse effects. It was scientifically confirmed that a number of aromatic and medicinal plants containing
biologically active substances with anti-inflammatory, antibacterial, astringent and similar actions could effectively reduce or eliminate a number of different symptoms caused by infection of the mucous membranes of the mouth and throat. Phytopreparations, containing specifically selected
herbal drugs, with biologically active ingredients exhibit a positive effect on the site of inflammation: antibiotic, antimicrobial, antiviral, emollient, anti-inflammatory, and astringent and thereby facilitate problems of impaired tissues and stimulate regeneration of the mucous membrane of the mouth, pharynx, tongue and gums. Synthetic mouth-care products (eg Hexoral solution - chlorhexidine gluconate as active principle), often in an enduring application can cause adverse side effects or lack of efficacy. Also, a vast number of natural products for this purpose contain substances of natural origin, but without a defined content of active principles. Taking into account that the morden medicine is nowadays faced with the problems of bacterial resistence to antibiotics, substances with antibacterial properties isolated from natural sources are in the focus of scentific and practical view of interest .
Despite the large number of nowadays known antibiotics and chemotherapeutics on the world market (over 200 kinds, including 50 kinds of penicillin, 70 kinds of cephalosporine and 20 kinds od quinolone), the problem of multiresistance of bacteria to antibiotics still persists. During 2001. only in the USA, 24,6 millions of kilograms of antibiotics has been produced for livestock production and veterinary medicine and about 3 millions of kilograms for aplication in human medicine. The consequence of this masssive antibiotic production is increasing the antibiotic resistance of bacteria and appearance of panresistance phenomenon -resistance to all available antibiotics. Multiresistant strains are multiplied daily and they have inhabited farms, hospitals, schools and environment and cause severe, in most cases fatal infections worldwide in animals and humans. On the other hand, pharmaceutical industry did not develop any new so called
„blockbuster" antibiotic for wide usage in human or veterinary clinical practice. There are several reasons for that: firstly, selective toxicity of many of the newest antimicrobials is too low, thus these new antimicrobials are not useful because of their high toxicity against host's cells.
Secondly, clinical investigations of new antimicrobials are very expensive and time consuming. And finally, for the marketing of new products, years are nedeed after new product could become available for consumers. So, studies of antibacterial effectt of non-antibiotical substances of different origin, including herbal extracts, are more present nowadays, with the objective to treat humans and animals in cases of infections induced by multiresistant strains of bacteria.
Previous research and empirical data regarding the biological and therapeutic properties of herbal active ingredients and their application represent the base for the appropriate selection of medicinal plants for phytopreparations, with favorable effect on the bacteria causing the inflammation of soft tissues of the mouth and pharynx. Complex biological active substances, ingredients of medicinal and aromatic plants such as essential oils, phenolic compounds, mucilage, minerals, enzymes and other secondary metabolites are responsible, in this specific case, for antiseptic action. The combined effects of active ingredients of our original
compositions, cover a positive impact on the normal function of the soft tissues of the mouth and
throat, including a strong antiseptic effect as well, which is required in the treatment of hoarseness, laryngitis, pharyngitis, tonsillitis and inflammation and pain mitigation in throat.
In the phytopreparations, intended for use as topical preparations, the employed substrates does not represent the inert carrier of active ingredients or plants extracts. Composition and physico-chemical characteristics of the substrate affect the bioavailability of the active substances and their therapeutic effect; hence substrates/carriers should be carefully constructed regarding physical-chemical properties which would enable the appropriate phytopreparation application in the treatment of the inflammation of mouth mucous membranes and pharynx. Substrates should be compatible with active ingredients, stable, non-irritating, non- sensitizating and enable to provide the stability of the drugs and suitable pH value. Besides, the administration should be convenient and facilitated; the carrier should adhere well to the skin and mucous membranes and, possibly, contribute to prolonged action of the active principles on the application site.
Microbial and anti-inflammatory activity of herbal drugs Usnea barbata L., Parmeliaceae Origanum heracleoticum L., Lamiaceae, Satureja montana L., Lamiaceae, Sideritis scardica Griseb., Lamiaceae, are well-known, but the present patent claims combinations that have not been mentioned in the recent or earlier literature data.
1. Usnea barbata L., Parmeliaceae, Old Man's Beard
The lichen and its main active component, usnic acid, are traditionally used for medicinal and cosmetic purposes, as well as in homoeopathy. They have significant antibacterial, antiviral, antiproliferative antimicrobial, antiinflamatory, antipyretic and analgetic activity.
2. Origanum heracleoticum L., Lamiaceae, Greek Oregano
Herbal drug - Origani heracleotici herba contains up to 3% essential oil and flavonoids. It has antimicrobial activity. It is used for treatment of the respiratory tract problems (cough, bronchitis), as well as for treatment of digestive and urinary tract disorders. It is widely used as spice.
Beside O. heracleoticum, the other species of the genus Origanum, such as Origanum vulgare L. are also widely used as antimicrobial and antifungal agents. Esential oil is considered to be the most responsible for biological activities due to presence of phenolic compounds
(thymol, 1 1.6% and carvacrol, 3.5%). The essential oil (at concentrations less then 2%) inibits growth of Candida albicans, Aspergilus niger, Acinetobacter baumanii, Staphylococcus aureus, Streptococcus faecalis, Bacillus subtillus. O. vulgare has antioxidant effects.
3. Sideritis scardica Griseb., Lamiaceae, Mountain Tea
Aerial parts at flowering stage (Sideritis herba) are used as a herbal drug. Aerial parts contain up to 0.6% essential oil, tannins, bitter substances, poliphenols, minerals, etc. Mountain
Tea has been used since old times in traditonal medicine of Southern Europe. Decoct and infuse of Mountain tea are commonly consumed in Greece during the winter period. It is used for treatment of cought, respiratory tract disorders, anemia and gastritis. This tea is used for enjoying and is greatly appreciated for its pleasant odor and colour.
4. Satureja montana L., Lamiaceae, Winter Savory
Aerial parts at flowering stage are used as herbal drug, Saturejae montanae herba. Herbal drug containes up to 2% essential oil (there are three chemotypes, carvacrol, thymol and linalool chemotype, among them carvacrol chemothype is the most appreciated), triterpenes, cinnamic acid derivatives, flavonoids. It is used as antiseptic, stomachic and carminative agent for its benificial effect in treatment of inflammation of the urinary tract, respiratory and digestive systems, inflammation of skin and mucosa. Winter Savory is widely used as a spice in meat and fish dishes. It is greatly appriciated by people, especially in the regions where it is widely distributed; it is considered to possess wide spectrum of biological properties. It is also called a „Men's Tea".
Herbal drugs may be used as active principles in different pharmaceutical compositions (tablets, capsules, creams, gels, fats, syrup, etc.). Compressed lozenges differ from conventional tablets in organoleptic properties; they disintegrate slower comparing to tablets and are less soluble. Disintegration process of lozenges obtained by compression of active substances and excipients is usually assisted by adding of small quantities of substances which promote decomposition process. Investigations were performed with numerous substances (starch, sodium starch glycolate, microcrystalline cellulose, sodium croscarmellose). The results have shown that the best effects were achieved with extragranular microcrystalline cellulose. Lozenges for the treatment of the soft tissues of the throat usually contain taste corrigents. Our formulations contain aroma of peppermint because of its characteristic taste and odor which masks the undesired aroma of active substances and at the same time reduces the sweetness of formulation
(lozenges/solution/gel) as a consequence of a high quantity of sugar present.
Mouthwashes are Water solutions for the treatment of the mucous membranes of the mouth. They are not supposed to be swollen. They can be in a form of solutions or concentrated solutions which should be diluted before the use. Spray is a solution aimed for the dispersion within the oral cavity and has a local action. These solutions are packed into vessels with dispensing system, optionally under pressure and with possible dose regulation. Sprays should provide appropriate dimensions of drops for their localization in the mouth or throat.
Gels for treatment of oral mucous membrane are described in the Sixth European Pharmacopoeia (Ph Eur 6.0) within the section Semi solid preparations for cutaneous use. Semi-
solid preparations for treatment of oral mucous membrane meet the requirements of the monography Semi-solid oromucosal preparations, for administration to the oral cavity or to the specific part of oral cavity

Although the extracts mixture showed good antibacterial activity against gram-positive bacteria, it has showed weak or no activity against gram-negative species, especially the members of Enterobacteriaceae family. This indicates that usage of this mixture will have no adverse effect on normal gastrointestinal flora of consumers.
Compressed lozenges that contain the combination of extracts showed antibacterial activity against S.pyogenes and S.aureus strains, including Methicillin resistant Saphylococcus aureus (MRSA) strains. According to the disc diffusion method, compressed lozenges showed antibacterial activity with 18-20 mm inhibition zones on the plates inoculated with investigated strains suspensions of 100 000 CFU/ml compared to clindamycin discs with 20-22 mm zones, and 25-30 mm inhibition zones of oriblettes on the plates inoculated with 10 000 CFU/ml, compared to clindamycin discs with 24 to 36 mm inhibition zones.
According to the broth macrodilution method, the compressed lozenges showed good antibacterial activity in the medium with bacterial concentrations of 100 000 and 10 000 CFU/ml, i.e. the total number of bacteria after the incubation was reduced 10 times, compared to controls without oriblettes in which number of bacteria has increased to the level where the proper counting was impossible.The number of 100 000 and 10 000 CFU/ml is not minor, on the contrary for the most microorganisms it is equal to infection dose.

The present invention will be demonstrated through the following examples which do not constrain the inventon:
Example 1.
Obtaining lichen extract by supercritical fluid extraction
Lichen is milled and sieved. Fraction caught between sieves of 0.2 and 0.6 mm is used for the extraction. 30 grams of milled and sieved lichen is placed in a 150 cm3 extractor. After reaching
the operating conditions (pressure and temperature), a continuous flow of supercritical fluid (0.5 kg / h) is established. Substances dissolved in the supercritical fluid are collected in the separator vessel due to the reduction of pressure. Extraction lasts until the raw material is exhausted.
Specific consumption of supercritical carbon dioxide is 24 grams of carbon dioxide per gram of lichen.
Obtaining extracts by continuous extraction in Soxhlet-apparatus
Solvent: Ethanol 70% (v / v)
a) 50 g of drug is comminuted and put in two paper tubes (20.00 g each, accurately weighed) b) Ethanol is pored over the drug (70%, v / v) in the amount of 2 '/.-volume of Soxhlet, so that the paper tube is soaked with solvent. It si left over night.
c) Turn on the water supply to the condenser and turn on the heaters to 5 until the solvent boils, then reduce to 3 or 4. Extract until bleaching.
d) After extraction turn the power off, leave the water until the solvent is completely cooled, transfer the extract into a glass, and rinse the extraction balloon with ethanol (70%, v / v) (3 x 10 ml)
e) Measure a tare of a balloon of 50 ml and evaporate the ethanol from extract in a vacuum evaporator
f) Leave the balloon with extract in an oven at 30 °C to dry the extract
g) Measure the mass of the balloon with the extract
Obtaining essential oils by hydrodistillation
200 g of plant material (Sideritis scardica, Satureja montana and Origanum heracleoticwri) is subjected to hydrodistillation in the Clevenger apparatus with the essential oil yield of 0.01 to 3.5% .
Example 2.
Production of compressed lozenges that contain combination (two, three or four) of plant extracts/essential oils
Wet granulation: Solution of binding matter is made by its dispensing (0,3-0,57 kg) over the surface of distilled water (0,1-0,77 kg) with posterior swelling during 10-25 minutes. Binding matter is dissolved after swelling by mixing at 700-1500 rpm. in the next 10-25 minutes. Mixing of powders is performed in a mixing vessel for high shear velocities during 20 minutes at 700 rpm: glucose monohydrate (1,50-2,15 kg); the extracts: Old Man's Beard lichen (Usnea barbata) in the range of 0,001-0,03 %, Greek oregano {Origanum heracleoticum) in the range of 0,10-0,50 %, mountain tea (Sideritis scardica) in the range of 0,10-0,70% and winter savory (Satureja montana) in the range of 0,10- 0,50% as well as saccharose (1,50-3,40 kg).
