What is the role of excipients?

The intended function of an excipient is to act as the carrier (vehicle or basis) or as a component of the carrier of the active substance(s) and, in so doing, to contribute to product attributes such as stability, biopharmaceutical profile, appearance and patient acceptability and to the ease with which the product …

Why are excipients important in a medicine?

Excipients are used to facilitate the manufacture and use of medicines. Without excipients, it would not be feasible to formulate some drugs into appropriate medicinal products. For others the removal of excipients would reduce the shelf life and make them uneconomic to produce or too expensive for users to purchase.

What are excipients used in tablets define and give examples?

Excipients used in tablet formulation may be classified into two groups: Those that help to impart satisfactory processing and compression characteristics to the formulation e.g. bulking agents/diluents, binders, glidants, and lubricants.

Do all drugs have excipients?

Pharmaceutical regulations and standards require that all ingredients in drugs, as well as their chemical decomposition products, be identified and shown to be safe. Often, more excipient is found in a final drug formulation than active ingredient, and practically all marketed drugs contain excipients.

How are drugs different from excipients?

Pharmaceutical excipients are substances other than the pharmacologically active drug or prodrug which are included in the manufacturing process or are contained in a finished pharmaceutical product dosage form.

Is sodium chloride an excipient?

Sodium chloride tablets are also available to replace salt lost through excess sweating to help prevent muscle cramps. Sodium chloride solution may also be used to dilute medications for nebulization and inhalation. As an excipient, sodium chloride may be regarded as nontoxic and nonirritant.

Are excipients regulated?

Under U.S. law, an excipient, unlike an active drug substance, has no regulatory status and may not be sold for use in food or approved drugs unless it can be qualified through one or more of the three U.S. Food and Drug Administration (FDA) approval mechanisms that are available for components used in food and/or …

What are drug excipients and how do they influence the effectiveness of the drug?

Pharmaceutical excipients are inactive substances other than the active ingredient, which are included in a drug formulation to serve several purposes. They can modify drug absorption, pharmacokinetics, and drug stability, while they help overcome the limitations of the API in terms of manufacturability.

Can excipients cause side effects?

Adverse effects due to excipients in drug formulations are generally uncommon but the potential for toxicity is increased at high mg per kg doses especially in neonates and infants. Dose related toxicity and hypersensitivity reactions are well documented in the literature.

Is sodium bicarbonate an excipient?

It can be used as: • the active therapeutic moiety e.g. in sodium chloride to replace physiological sodium; part of the active substance e.g. when an active moiety is presented as a sodium salt, such as in sodium diclofenac; part of the excipient e.g. sodium bicarbonate.

Why is titanium dioxide in medicine?

In the pharmaceutical industry, titanium dioxide is used in most sunscreens to block UVA and UVB rays, similar to zinc oxide. It is also commonly used as pigment for pharmaceutical products such as gelatin capsules, tablet coatings and syrups. It can be used as an opacifier to make pigments opaque.
