What are pharmaceutical Excipients?
Pharmaceutical excipients refers to additives used in production and production used in pharmaceutical preparations.They are substances that have previously undergone a logical review of safety because they include the pharmaceutical preparations’ active ingredient. In addition to serving as a filler, carrier, and stabilizer, pharmaceutical excipients also have other important roles to play, such as solubilization, hydrotropy, sustained and controlled release, which possibly affects the quality, safety and effectiveness of pharmaceutical preparations.
The selection and application of pharmaceutical excipients according to the nature of drugs and dosage forms is the essence of the pharmaceutical formulation design. Pharmaceutical excipients are the basic materials or important components of pharmaceutical preparations, which performs as the material base of manufacturing and developing of pharmaceutical preparations playing a critical role in formulation.Excipients used in pharmaceutical preparations not only affect the physical form but also have a big impact on the therapeutic effect and safety. The material foundation that ensures the development of dosage forms and preparations is the consistent quality and functional diversity of pharmaceutical excipients.
There are many different sources for pharmaceutical excipients, including natural, synthetic, and semi-synthetic materials. Regardless of the source, pharmaceutical materials should be safe, chemically stable, compatible with other excipients and medications, and not interfere with preparation analysis. additionally, they are typically anticipated to perform their duties with relatively little consumption.
Classification of pharmaceutical Excipients
Pharmaceutical excipients can be classified according to different methods such as their source,function,application or route of administration. They can be categorized into natural products,semi-synthetic products and synthetic products.
According to the function and application,pharmaceutical excipients can be categorized into 65 unique categories including pH adjusting agents,chelating agents,inclusion agents,coating agent,protective agents,humectant,disintegrants,surfactants,virus inactivating agents,tonic,precipitants,film forming polymers,aroma,lyoprotectant,CO2 adsorbents,foaming agents,fragrant agents,preservative,excipients,desiccants,stiffening agents,buffering agents,sustained and controlled release materials,adhesive agents,flavoring agents,antioxidants,wetting agents,colorants and many more.
According to the route of administration,pharmaceutical excipients can be categorized as excipients used for oral ,parenteral,mucosal, transdermal/topical,intranasal/intra-respiratory and ophthalmic administration, etc.
Some excipients can be used in various routes of administration but the quality and quantity differ.for example excipents used in injections should comply with the requirements of injections,and they should meet the requirements of oral administration when used in oral dosage forms. Descriptions must be labeled on the package of pharmaceutical excipients such as “Pharmaceutical Excipients”, the applications(routes of administrations),etc.
The importance of pharmaceutical Excipients?
Pharmaceutical Excipients play a variety of roles in pharmaceutics,including:
1. Determine the physical form of dosage forms:pharmaceutical excipients dictate the physical form of dosage form such as addition of solvent into liquid preparation,addition of diluents and binders into tablets,addition of proper base into ointments or suppositories.
2. Facilitate the manufacturing process: Pharmaceutical excipients make the manufacturing process smoothly,such as addition of solubilizers,hydrotropy agents,emulsifiers and other excipients into liquid preparation as required,addition of glidants and lubricants into tablets to improve characteristics of powders and smooth the compression process.
3. Increase the stability of drugs:pharmaceutical excipients increase the stability of drugs such as additional chemical stabilizers,physical stabilizers(suspending agents,emulsifiers,…)and biologic stabilizers(preservative) etc.
4. Modify the action site and time of drugs, or satisfy the physiological demand: pharmaceutical excipients introduce functional properties to pharmaceutical preparations,such as fast release,sustained release,enteric dissolving,targeting,temperature-sensitive,bioadhesive,biodegradative,and also satisfy the physiological demands such as pH adjusting agents,isotonic agents,flavoring agents,analgesics,and colorants,etc.
New pharmaceutical excipients play important roles in many aspects such as improvement of the quality,promotion of the performance,development of novel dosage forms and enhancement of bioavailability. However ,more recently,the development of pharmaceutical excipients has attracted more attention by pharmaceutical scientists because of the important role in the development of modern dosage forms and pharmaceutical preparations.
Challenges in using certain excipients
- Regulatory Organizations Demand pharmaceutical excipients that are safe and of high quality.
- Drug manufacturers are accountable for the integrity, safety, and security of the supply chain.
- Lack of New Pharmaceutical Excipients
Conclusion:
In addition to the active ingredient, medicines also contain other substances that are crucial to their production, stability, and performance. Although these components ought to be harmless, sensitive people may have negative side effects from them. Finding out about these reactions and the proper safety information will help to guarantee the patient’s safety.
