classification of dosage forms based on route of administration

Rapid onset of action due to rapid access to circulation. Examples of diluents include ground limestone, dicalcium phosphate, dextrose, and kaolin. Parenteral dosage forms and delivery systems include injectables (ie, solutions, suspensions, emulsions, and dry powders for reconstitution), intramammary infusions, intravaginal delivery systems, and implants. The most common medication dosage forms are liquids and solids. These include many kinds of liquid, solid, and semisolid dosage forms. The oral route of administration is the most widely used in cattle, pigs, and poultry. Drugs are given in different forms. However, this may not be the case in species in which the emulsifying properties of skin secretions and the large numbers of follicles and glands per unit surface area must be considered (eg, cattle and sheep). Particle or droplet size largely determines the extent to which the drug penetrates the alveoli. The principal route of percutaneous absorption for most drugs in people is the intercellular pathway, making the intercellular lipid matrix the primary barrier to absorption. The dust associated with powdered premix formulations can have serious implications for both operator safety and economic losses and is reduced by including a vegetable oil or light mineral oil in the formulation. Because the muscles lie below the skin and fatty tissues, a longer needle is used. A different type of applicator is used to insert CIDR devices into the vaginal cavities of sheep, goats, and cattle. Which of the following intravenous diuretics is the most appropriate treatment for life-threatening pulmonary edema caused by CHF? In addition, excipients in the formulation modulate consumption by altering the palatability and/or the hardness of the medicated block. Numerous methods are used to apply parasiticides to farm animals (see below). In addition, many pour-on formulations display endectocidal activity in cattle. These include route of administration, dosage, set and setting, and personal and environmental factors. Zinc sulfate, used as a dip additive to minimize the spread of dermatophilosis in sheep, also adversely affects emulsions. Pharmaceutical form: liquid, ready to use. They are applied to the external auditory canal. Preparation of Dilution. These dosage forms and delivery systems as well as the special considerations relating to intra-articular injections, recombinant proteins and peptides, and vaccines are discussed below. Bolus intravenous injection. Nonmedicated syrups are used as vehicles for water-soluble drugs. The reddish brown color of iodine tincture produces skin staining that delineates treated skin. The major causes of chemical instability are proteolysis, deamidation, oxidation, and racemization. Active ingredients that are soluble in water-immiscible organic solvents are frequently formulated as emulsifiable concentrates. Eugenol is present in A. Tulsi B. Fennel C. Cardamom D. Coriander 2. Oral Route: Oral route is the most common route of drug administration. The physical, chemical and therapeutic integrity of the dosage form should be maintained during storage. Others are used for their lubricant properties. Two delivery systems for DNA vaccines have been reported. This time we are going to highlight the renowned oral dosage forms. Caking in a premix formulation may be caused by hygroscopic ingredients and is addressed by adding small amounts of anticaking agents such as calcium silicate, silicon dioxide, and hydrophobic starch. • Tarceva is not recommended for use in combination with platinum-based chemotherapy [see Clinical Studies ]. These systems are used for estrus synchronization in sheep, goats, and cattle. 1. Other formulation additives include suspending agents, surfactants, and other excipients to ensure the production of a shelf-stable, pourable product. In one system, the segment of DNA is coated with gold and administered to the patient using a “gene gun.” The other delivery system uses a viral vector or plasmid to carry the DNA segment into the patient. Start studying chapter 5: dosage forms, abbreviations and route of administration. In this administration the drug is administered in the gaseous form. Suspension concentrates are used topically as pour-ons, plunge and shower dip concentrates, and jetting fluids. The use of dusting powders is indicated on skin folds and contraindicated on wet surfaces, because caking is likely to result. The three main parenteral routes of drug administration are IV, IM, and SC, and in all cases administration is usually via a hollow needle. The particles progress to the abomasum, where some are trapped in the mucosal folds and release copper. Most drugs are absorbed from small intestine but some are absorbed from stomach and colon. Two types of insecticide-releasing ear tags to control flies on cattle are available. The THREE LETTER CODE (TLC) was introduced as a dosage Form Code in the audits during the middle of the 1960s. Various dosage forms composed of one or more bioactive macromolecules as the active ingredient(s) with number of excipients have been designed with approved effects against number of diseases. A humectant (eg, glycerin or propylene glycol) is used to prevent the paste that collects at the nozzle of the dispenser from forming a hard crust. Antioxidants maintain product stability by being preferentially oxidized over the shelf life of the product. The dosage form should be free from an interaction between components, with packaging materials and environmental factors (heat, humidity, oxygen, light). Both types rely on the animal’s ear and head movements and grooming to transfer insecticide from the surface of the ear tag to the animal’s skin or to other animals. Special Dosage Form Considerations with Intra-articular Injections: Specialized Topical Dosage Forms and Delivery Systems for Transdermal Drug Delivery: Sulfonamides and Sulfonamide Combinations. The control of internal and external parasites of companion and food-producing animals has led to development of specialized dosage forms, delivery systems, and application methods unique to veterinary medicine. In horses, solutions and suspensions are administered by nasogastric tubes, pastes are applied to the tongue, and granules are added to rations for ingestion. The oil retards evaporation of the insecticide and enhances adherence to the animal’s coat. By comparison, water-in-oil emulsions are emollient and cleansing. Granules and powders generally behave similarly; however, granules must deaggregate before dissolution and absorption. Advantages of liquid dosage forms 3. Common dosage forms include pill, tablet, or capsule, drink or syrup, and natural or herbal form such as plant or food of sorts, among many others. There are several types of dosage forms, depending on the method/route of delivery of the medicine. Additionally, the incorporation of a binder such as lignin sulfonate in blocks manufactured by compression, or magnesium oxide in blocks manufactured by chemical reaction, increases hardness. For example, molasses increases palatability, and sodium chloride decreases it. Powders have better chemical stability than liquids and dissolve faster than tablets or capsules because disintegration is not an issue.
