For example, it can be difficult to determine which excipients will keep the dose high and still maintain shape, solubility, and stability. Water-soluble or water miscible base – they dissolve or disperse in rectal secretions. aureus), therefore, stability of rectal formulations at high temperatures is a key consideration. These excipients can vary widely, leading to different effects on the body. Materials and methods. AAPS PharmSciTech. 4 Other Excipients Used in Suppository Dosage Forms. Salofalk suppositories are light beige coloured, torpedo-shaped suppositories. Suppository excipients generally comprise lipophilic fatty bases, which melt at the temperature of the rectum, or water-soluble bases, Suppositories are the most common rectally administered dosage form. Paracetamol 250 mg/suppository. D. Excipients. They are are semi-synthetic hard fat bases comprising fatty acid esters. Basics of Compounding: Excipients Used in Nonsterile Compounding, Part 10: Rectal Suppository Bases July 2021 International Journal of Pharmaceutical Compounding 25(4):304-309 Lipids have always been essential components of pharmaceutical dosage forms. Set A needs 12 suppositories – each containing 50mg of drug X whereas set B needs both 50mg of drug X and 300mg of drug Y in all 12 suppositories. , in Essential Chemistry for Formulators of Semisolid and Liquid Dosages, 2016 Abstract. consideration. ). Other materials, such as aspirin combinations, Common functional class of excipients and their examples have been discussed next. MALWAL, 2NILESH. Classification and Characteristics of Suppository Bases. 77 g of cocoa butter will be needed for each Designing and developing suppository formulations for anti-HIV drug delivery. Some investigations have been made on water-soluble and emulsion type bases. Pengfei Gao and Miao he Development and application of suppositories Jan 2016 For example, a hydrocortisone suppository may replace a hydrocortisone tablet or capsule; Rectal solutions, emulsions and suspensions may contain excipients, for example to adjust the viscosity of the preparation, to adjust or stabilise the pH, to increase the solubility of the active substance(s) b) Suppository; c) Solution; d) Suspension; Correct Answer: b) Suppository. Commonly used example is Polybase PEG suppository bases are formulated so they do not melt at body temperature, but rather dissolve in body fluids. Oleaginous bases or oily bases The vaginal suppository formulation further includes at least one excipient (hereinafter interchangeably referred to as “excipients”) capable of carrying/supporting the active ingredients. pharma-excipients A well-known example is the different water uptake capacity of Microcrystalline cellulose based on the drying process applied during production which can have an influence in wet Rectal solutions, emulsions and suspensions may contain excipients, for example to adjust the viscosity of the preparation, to adjust or stabilise the pH, It will help insertion but the effect on irritation is questionable because much more water will be attracted when the suppository dissolves. The pharmaceutical ingredients solubilize, suspend, thicken, dilute, emulsify, sta-bilize, preserve, color, fl avor, and fashion medici-nal agents into effi cacious and appealing dosage forms. Beyond their physicochemical characteristics. These semi-solid forms can be available in two forms- Conventional semi-solid dosage forms Pharmaceutical formulation is the multistep process where the active drug is mixed with all other components by considering the factors of particle size, polymorphism, pH, and solubility and becomes the final beneficial medicinal product. Also, a number of example bases are presented and discussed. For example, in the preparation of solutions, one or more solvents are used to dissolve the drug SUPPOSITORIES: solid medicinal dosage forms formulated and prepared for administration into body cavities • • Rectal, vaginal (pessary), urethral suppositories • Melt at body temperature or The hydrophilic class of suppositories include excipients that dissolve in the presence of water. 2009) . 2006 Kobayashi M, Samejima M (1982) Influence of the liquid phase coexisting in fatty suppository bases on the polymorphic transition rate. Tablets are solid dosage forms of medicaments that are manufactured by mixing one or two drugs in certain amounts to induce therapeutic effects. Therefore, it is imperative that formulators are able to accurately and completely specify the key chemical and physical properties of those excipients. Patient Comfort – fatty The selection of a rectal suppository base can be critical for proper compounding, storage, administration, and release of the drug for the patient. EXCIPIENTS of SUPPOSITORY Handbook of Pharmaceutical Excipients: Suppository bases, hard fat. Finally, the absolute bioavailability of the two types of HTS was evaluated using a previously Suppositories can be used, for a systemic action against fever, pain or arthritis for example, or a local action against At Gattefossé, we know how important the selection of the suppository base is, and we have developed guidelines to help select the right simplify existing formulations by reducing the number of excipients ; The addition of surfactants to suppository formulations is referred to in the scientific literature, but their effects on drug availability remain uncertain. Some common uses for a rectal suppository are: Constipation. additives diluents excipients preservatives. com. Suppository excipients generally comprise li-pophilic fatty bases, which melt at the temperature of the rec-tum, or water-soluble bases, which dissolve in the rectum. 4 CLINICAL PARTICULARS 4. 4 Clinical CD Formulation is a leading manufacturer of excipients, serving the pharmaceutical industry to help it improve the performance of its products. 5. 15 -25oC and melts at body temp (for oil based suppositories) • Amorphous, smooth, non-irritating vehicle • Medicinally inert without side effects Our suppository excipients / bases have been optimized to provide excellent drug delivery for both solid and liquid APIs, across a range of water solubility. An aesthetically appealing appearance E. There seems to be little or no work done with such compounds as plastics, synthetic resins, and other similar condensation products. Vaginal dosage forms are administered for a local effect only. Some diluents (such as microcrystalline cellulose) are often used as dry Binder excipients hold the ingredients of the formulation together, while bestow API with propriate volume.
