Studies viii. Dash,., Singh,. These substances are called excipients, and they are intentionally included in a drug product to serve different pharmaceutical purposes, thus ensuring product acceptability in terms of manufacturability, appearance and performance. Insoluble lubricants.g., Magnesium stearate, glyceryl behenate, stearic acid, glyceryl palmitostearate etc. In addition to being many more times sweeter than sucrose, artificial sweeteners have the advantage of not impacting blood sugars of diabetic or pre-diabetic patients, and they are considered non-cariogenic. It is important that the colour is uniformly distributed throughout the tablet. In some cases, lubricants reduce inter-particulate friction and thus, improve flow rates of powders or granules. Bulking Agents/ Diluents/ Fillers, these are approved excipients added to any tablet formular when the quantity of active pharmaceutical ingredient is very small. Ansels Pharmaceutical Dosage Forms and Drug Delivery Systems. Some favouring materials are more effective than others in masking or disguising the undesirable taste of drug substances. Various factors have been identified to influence the actions of disintegrants and they include: The amount/ concentration of the disintegrant in the formular. The type of disintegrant used. By clicking the Accept button below, you are consenting to receive and store cookies from our site. The quantity of bulking agent that appears in a formula is normally determined by the quantity of the drug, the nature and amount of other ingredients in the formulation. The type and quantities of each excipient used depend on the type of tablet desired and the process employed. Lactose is a common bulking agent used in both tablet and capsule formulations as it fulfils most of the ideal characteristics of bulking agents.

Adsorbents In addition to the drug substance(s compressed tablets also contain adsorbents. Concerns over the safety of these agents in pharmaceutical formulations generally arise from their adverse effects in food substances. De Faria, Marcio. The concentration may have a direct relationship with the rate of disintegration pénal until it gets to maximum after which disintegration rate decreases with increase in concentration of disintegrants. They should be chemically inert, non-hygroscopic, hydrophilic and must exhibit good compression properties. Tablet disruption following gas production (carbon dioxide) as seen in effervescent tablets is another mechanism used to enhance tablet disintegration.

Other examples of bulking agents used in tablet manufacture include mannitol, dicalcium phosphate, calcium sulfate, dry starch, cellulose, kaolin, sodium chloride, anhydrous lactose, sorbitol, sucrose etc. The excipient is of particular importance if the conventional tablet contains a bitter drug substance(s) or, more importantly, if the tablet is a chewable tablet. Bandeira, Alexandre Cestari and Cristianine. Although individuals tastes and flavour preferences differ, cocoa-flavoured vehicles are considered effective for masking the taste of bitter drugs.

Conclusion Excipients are essential in the formulation of tablets as it ensures successful manufacturing process and quality of the resultant formulation. They are added as dry powders.
