Definitions
- composition containing herbal ingredients
- the present invention relates to a pharmaceutical composition in solid form for oral administration of sustained-release phytochemicals.
- One way to slow the release of an active ingredient in a solid pharmaceutical composition is to embedding the drug in a
- Polymer matrix The delay or slowing down of the release of the active substance depends on the choice of matrix formers, the choice of additional auxiliaries, the solubility of the active substance and the percentage of the individual components in the solid pharmaceutical composition.
- the release of a drug embedded in a matrix for example in the form of a tablet, at a constant rate, ie linear.
- Known drugs with incorporated in a polymer matrix Wrkstoffen usually contain synthetically produced uniform chemical compounds as active ingredients.
- phyto-oral slow-release oral medicines are not known.
- the slow release of pharmacologically active substances from plants, plant constituents, plant extracts and oils (hereinafter referred to as herbal active ingredients) from solid pharmaceutical compositions presents a particular challenge from a pharmaceutical point of view because the herbal medicines represent a mixture of different active substances with different dissolution properties , Although non-sustained herbal preparations lead to a rapid effectiveness, but only to a limited extent. It is therefore desirable for the patient to extend the efficacy to a longer period of time.
- the object of the present invention is to provide a pharmaceutical composition in solid form for oral administration of delayed-release plant substances
- the invention relates to a pharmaceutical composition in solid form for the oral administration of sustained-release phytochemicals comprising a vegetable preparation containing the pharmacologically active substances and a mixture of a water-soluble and a water-insoluble polymeric matrix former.
- tablets, minitablets, pellets, film-coated tablets, capsules, for example, soft gelatin capsules, and related forms are contemplated, especially tablets, minitablets, and pellets, preferably tablets.
- Contemplated herbal ingredients are e.g. Roots (e.g., gentian root), rhizomes, barks (e.g., willow bark), flowers (e.g., melissa flowers), leaves (e.g.
- Roots e.g., gentian root
- rhizomes e.g., gentian root
- barks e.g., willow bark
- flowers e.g., melissa flowers
- leaves e.g.
- Nettle leaves Nettle leaves
- seeds e.g., Indian psyllium husks, linseed
- leaves with flowers e.g., Chinese psyllium husks, linseed
- Herbal Extracts and Extract Combinations are Hypericum Extract (St. John's Wort), Ginkgo Biloba Extract, Grapeseed Extract, Passion Flower Extract, Birch Leaf Extract, Nettle Root Extract, Ivy Extract, Silver Thistle Extract,
- Contemplated vegetable oils are e.g. Evening primrose oil, borage seed oil, menthol oil and chamomile oil. Preference is given to a pharmaceutical composition according to the invention comprising a plant extract, in particular hypericum extract. Equally preferred is a pharmaceutical composition according to the invention comprising a Ginkgo Biloba extract. If a water-insoluble matrix former is used, an almost uniformly delayed release will be observed. Depending on the choice of water-insoluble
- polymeric matrix formers are used in the form of a mixture of polymeric water-soluble and water-insoluble matrix formers.
- Polymeric water-soluble matrix formers are, for example, hydroxypropylmethylcellulose (hypromellose, HPMC), hydroxypropylcellulose (HPC), poloxamers, polyvinylpyrrolidone (povidone) and the like.
- HPMC is a mixture of alkyl-substituted cellulose with different degrees of polymerization and degree of substitution by methyl and 2-hydroxypropyl groups, and is commercially available in various viscosities, for example as Methocel TM from Colorcon. Poloxamers are
- Block copolymers of ethylene oxide and propylene oxide known as pharmaceutically usable matrix formers under the trade names Lutrol TM.
- polymeric water-insoluble matrix formers for example, ethyl cellulose
- Vinylpyrrolidone / vinyl acetate copolymers or polyvinylpyrrolidone / polyvinyl acetate mixtures for example Kollidon SR TM
- polyacrylic acid copolymers eg Carbopol TM, polymers of acrylic acid with polyalkenyl ether, eg with allyl-pentaerthritol, or with divinyl glycol
- polymethacrylic acid ester or methacrylic acid ester copolymers eg Eudragit TM NM 30 D, considered.
- the aforesaid water-insoluble polymers and copolymers are commonly used as film-forming agents for coating tablets, capsules and the like.
- the active ingredient is released completely from the solid pharmaceutical preparations.
- the desired release rate can be determined by suitable
- the ratio of water-soluble to water-insoluble matrix former is between 15:85 and 85:15, preferably between 25:75 and 75:25, more preferably between 35:65 and 65:35.
- compositions contain plant fractions of over 50%, preferably over 60% and particularly preferably over 65%, and the
- Matrix former or the mixture of matrix formers in a proportion of 15 to 50%, preferably 25 to 35%, most preferably by 30%.
- compositions according to the invention optionally contain adjuvants, for example carriers customary for solid oral dosage forms, e.g.
- microcrystalline cellulose microcrystalline cellulose, silica, xanthan, magnesium aluminum silicate,
- Calcium silicate calcium phosphates, magnesium phosphates, alumina or titania
- Thinner e.g. Calcium carbonate, calcium sulfate, hydrogenated vegetable oil, kaolin, magnesium carbonate, tribasic calcium phosphate, talc or sodium chloride
- Lubricant e.g. colloidal silica, starch or talc
- Mold release agents e.g. Calcium stearate, zinc stearate, magnesium stearate, stearic acid, fumaric acid, glycerol monostearate,
- Glycerol palmitostearate mineral oil, sodium benzoate, sodium lauryl sulfate, sodium stearyl fumarate, talc, hydrogenated castor oil or hydrogenated castor oil; Color pigments, e.g. Titanium dioxide, iron oxides, indigotin lacks or erythrosin lacks; Sugar, e.g. Mannitol, sorbitol, dextrins, maltodextrins, inositol, isomalt, lactitol, maltitol and xylitol; and other
- Flavorings for example flavors or artificial sweeteners, e.g. Acesulfame, aspartame, cyclamate, saccharin, sucralose or thaumatin.
- Further contemplated excipients are polyhydroxy compounds, for example ethylene glycol, propylene glycol or butylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and polyethylene glycol, glycerol or partially etherified with ethylene oxide glycerol derivatives.
- compositions according to the invention may further comprise auxiliaries which, owing to their good solubility, form pores in the polymeric matrix.
- auxiliaries which, owing to their good solubility, form pores in the polymeric matrix.
- water-soluble substances are generally considered, such as sugars, for example mannitol, sorbitol, isomalt, glucose, sucrose, maltitol and erythritol.
