Dosages tinctures

Liquid Dosage Forms. Simple aqueous solutions, symps, elixirs, and tinctures are prepared by dissolution of solutes in the appropriate solvent systems. Adjunct formulation ingredients include certified dyes, flavors, sweeteners, and antimicrobial preservatives. These solutions are filtered under pressure, often using selected filtering aid materials. The products are stored in large tanks, ready for filling into containers. QuaUty control analysis is then performed. 

Dosage forms of naturally occurring materials having therapeutic activity are prepared by extractive processes, especially percolation and maceration. Examples of such dosage forms have included certain tinctures, symps, fluid extracts, and powdered extracts. 

Back cohosh, a herb reported to be beneficial in managing symptoms of menopause, is generally regarded as safe when used as directed. Back cohosh is a member of the buttercup flower family. The dosage of standardized extract is 2 tablets twice a day, or 40 dropsof standardized tincture twice a day or one 500- to 600-mg tablet or capsule three times daily. Back cohosh tea is not considered as effective as other forms Boiling of the root releases only a portion of the therapeutic constituents... 

In contrast to the C. sativa tincture, Marinol soft gel capsules possess clear advantages. Firstly, they contain a single component in an accurate dosage. Secondly, it uses sesame oil as the carrier, making resorption significantly more reliable and also stabilizing the rather sensitive THC molecule. 

Tinctures are very concentrated. For most elder flower tinctures, an appropriate dose would be 20 to 40 drops in a bit of water. This can be taken 3 times daily for a chronic condition. However, if it is an acute condition, once every 1 or 2 hours that you are awake would be more appropriate. To determine dosage for a child, to treat a fever, for example, take the weight of the child and divide by 150. Thus a 50-pound child would get 1/3 of the adult dose. The tincture can be put in a bit of water or juice to dilute the taste of the alcohol. 

Hydroalcoholic extracts are made when the active constituents are insoluble in water or when a concentrated dosage form is desired. Hydro alcoholic extracts use concentrated alcohol in varying proportions with water as a solvent. Hydroalcoholic extracts are categorized as tinctures or fluid extracts, depending on the amount of alcohol used. Some patients who simply do not like the taste of alcohol may be counseled to put the dosage of tincture drops into a cup of hot liquid and let it stand for a few minutes to evaporate off most of the alcohol before ingestion. An example of an ethanolic extract is echinacea [5,6]. 

Some herbs may be available in many dosage forms, and the form may affect the dose that is given. Recommended dosages include 2 3 g of dried valerian or valerian extract given one to several times a day, or as a tea with 2-3 g of valerian being used per cup one to several times a day, with 2.5 g being equivalent to one teaspoon [7]. The recommended dose of valerian tincture is one half to one teaspoonful (2.5 5 mL) one to several times daily. 

Numerous reports concerning the stability of neomycin in various dosage forms have been published. Simone and Popino298 studied the stability of neomycin in liquid dosage forms such as nasal drops, mouth washes and tinctures. The antibiotic was stable in all the formulations tested, except Dobells solution (a mouth wash), for at least 6 months at 20°C. Some formulations were stable for considerably longer. 

St. John s wort and some individual constituents of the preparations have been administered orally, topically, and intravenously in various pharmaceutical formulations, including tinctures, teas, capsules, purified components, and tablets. These botanical preparations of St. John s wort are prepared from plant components (i.e., flowers, buds, and stalk) whose content of the wide array of structurally diverse bioactive constituents may differ (Table 1 and Fig. 2). Many commercial tablet and capsule formulations of St. John s wort are standardized using the ultraviolet absorbance of the naphtho-dianthrones, hypericin, and pseudohypericin, to contain 0.3% hypericin content. Thus, a 300 mg dose of St. John s wort contains approximately 900 pg hypericin per dose. Despite the standardization of dosage forms... 

Dried Echinacea pallida root extract (1 5 tincture, 50% ethanol) is given at a dosage of 900 mg/d. E purpurea freshly pressed juice is given at a dosage of 6-9 mL/d in divided doses two to five times daily. Echinacea is generally taken at the first sign of a cold. 

Solutions. For oral solutions, elixirs, syrups, tinctures, or other solubilized forms, in vivo BA and/or BE can be waived [21 CFR 320.22(b) (3) (i)]. Generally, in vivo BE studies are waived for solutions on the assumptions that release of the drug substance from the drug product is self-evident and that the solutions do not contain any excipient that significantly affects drug absorption [21 CFR 320.22(b)(3) (iii) ]. However, there are certain excipients, such as sorbitol or mannitol, that can reduce the BA of drugs with low intestinal permeability in amounts sometimes used in oral liquid dosage forms. 

Liquid dosage forms often can be directly asayed or simply diluted with water or mobile phase prior to testing. Benzethonium chloride tincture, prilocaine hydrochloride [3, pp. 173 and 1287], and numerous biological products such as OncoScint CR/OV (a monoclonal antibody DTPA conjugate) are examples. 

One of the challenges facing early, as well as contemporary, chemists is how to extract the pharmacologically active principle (such as an alkaloid) from a plant. This is desirable because it allows identification, assessment of pharmacological effects, constant dosage, and the opportunity to create liquid forms of the extract. For example, soaking plants in alcohol (ethanol) creates a tincture, which was, undoubtedly, one of the first organic extractions performed by man. 

Nonsolids Typical liquid-based oral dosage forms are elixirs, emulsions, extracts, fluid extracts, solutions, gels, syrups, spirits, tinctures, aromatic waters, and suspen-... 

Another relevant variable is the dosage form when a herbal tea is prepared by hot extraction from valerian root, up to 60% of the valepotriates remain in the root material and only 0.1% can be recovered from the tea. A freshly prepared tincture contains 11% of the valepotriates originally found in the root material. Storage at room temperature rapidly reduces this to 3.7% after 1 week and 0% after 3 weeks. In view of this rapid degradation, it is not surprising that commercially available tincture samples yield baldrinals. 

Most commercially available preparations of hypericum in the United States are dried alcoholic extracts in a solid oral dosage form. Other preparations include the dried herb, teas, tinctures or liquid extracts (2). The following is a list of a few of the available formulations ... 

To make a tincture, which is a hydroalcoholic (water and alcohol) extract, use 1 part semifresh berries for every 3 parts of solution made up of 70 percent ethyl alcohol and 30 percent water. The dosage is 3 to 4 milliliters (60 to 80 drops), three to four times a day. Eclectic practitioners believed that the best preparation of Serenoa is made with the fresh ripe berries. The extract should have a strong, ethereal, aromatic flavor and will precipitate when it is mixed in large amounts with water. In small amounts it produces an opalescent mixture. If it is rubbed between the fingers, a greasy sensation occurs, and the pronounced aroma of the berries is quite obvious. 

This makes 1000 cubic centimeters of tincture. Dosage of the mother tincture is 1 to 60 drops. Homeopathic medicine also uses this tincture in dilutions of 3 times and higher. 

I initially used Serenoa repens tincture to loosen chronic respiratory mucus that was resistant to other herbal expectorants. The results were positive. The extract was made using 2 parts Korbel brandy to 1 part fresh ripe Serenoa repens whole berries in 2-quart jars. The crushed berries remained in the extract. Dosage was 1/2 ounce per day. 

A common creeping climbing herb of disturbed woodlands and waste areas, cleavers can also be used as a bladder and prostate remedy. The fresh herb tincture is a nonirritating diuretic and a mild anti-inflammatory for the bladder, ureters, spermatic chord, prostate, and vas deferens. It works slowly to reduce irritation and pain and increase urinary flow. Tincture of the fresh herb is the preferred preparation, as the tea has only slight activity. The dosage of tincture is 60 to 80 drops three to four times a day. 

To make a tea from the recently dried rhizome, place 2 teaspoons in 8 ounces of boiling water, decoct 10 minutes, and steep 1/2 hour. Take 2 to 3 cups per day. Dosage of the tincture is 40 to 60 drops four times per day.
