Active Ingredients and Excipients

Pharmaceutical drugs, veterinary drugs, formulation combine two core components – the active ingredients and excipients. 

The active ingredient is the central ingredient that is responsible for the intended therapeutic, medicinal, or biochemical effects in a recipient.

Excipients, on the other hand, are substances other than the core drug or agrochemical component that facilitate the manufacture, stability, delivery, and function of the drug. They are typically inert (non-medicinal) components of a drug that do not have any medicinal or biochemical effect.

Arichem Limited imports a broad range of high-quality active ingredients and excipients from the world’s top manufacturers to meet your formulation requirements. We supply these raw materials in a range of quantities from bulk supplies to smaller quantities in gallons and other types of packages.

Active Ingredients

Active pharmaceutical ingredients are the raw materials used in the manufacture of various drugs. They are available in various forms including powder and crystals. An active ingredient cannot be used solely or directly for clinical purposes but only during the processing and packaging of clinical drugs. Active ingredients are the components in drugs that are responsible for the affecting the intended changes in the system including diagnosis, symptom relief, treatment, or disease prevention.

Arichem sources and supplies only the active pharmaceutical and agrochemical ingredients that are developed through processes and equipment that comply with the Current Good Manufacturing Practice (CGMP). This is the guarantee we have that the active ingredients that we supply to our clients are of the highest quality and purity while at the same time remaining stable for the period intended for their use. Further, we ensure that we source only the ingredients whose chemical structure of their molecules is well known and approved.

Arichem will deliver to you active ingredients in bulk or any other quantity that you wish. Therefore, for whatever active ingredient you need, such as paracetamol powder, Ibuprofen, or Diclofenac Sodium for drug manufacturing, you can rely on Arichem as your trusted reliable supplier. 

Active ingredients are used for the formulation of a range of products including:


  • Pharmaceutical drugs
  • Cosmeceuticals
  • Dietary supplements
  • Cleaning products and detergents
  • Sanitizers


Commercially available drugs are formulated in four main forms including tablets, capsules, liquids for instance the cough syrups, or fluids most often used for delivery of the drug through intravenous infusion in hospitals.

Other common forms in which drugs are available including topical creams, gels, implants, inhalers, transdermal patches, and suppositories. Drugs in their various forms contain a very small portion of active ingredients. The active ingredient is packaged along with excipients during processing.

Excipients are the inactive ingredients present in drugs other than the active ingredient. While these inactive ingredients may not have any biochemical effects in a recipient, they are equally essential components of a drug and typically represent the bulk, accounting for up to 90% of drugs.

Excipients facilitate the delivery and absorption of the active ingredient into the human, animal, or plant system where it is intended to affect biochemical and medicinal changes.

Excipients in both original and generic versions of drugs are considered “GRAS” meaning generally recognized as safe for consumption.

The role of excipients in a product

The difference between an active ingredient and excipients is the role that they play in a drug. Aside from facilitating the design of different drug forms and the delivery of the active ingredient for effective absorption into the body, excipients also play the following roles:


  • They create the aesthetics that help with product identification
  • They act as a buffer and preservative to protect the active ingredients from denaturing and give the drug a full shelf life
  • They are used to stabilize active ingredients in medications
  • They aid the process of manufacturing in formulating the form, shape, and color of drugs
  • They act as fillers where the active ingredient is not sufficient to be formulated into a complete drug whether in the form of a tablet, capsule, or syrup
  • They are used as binding agents to hold the ingredients of a formulated product together
  • They are used to coat capsules and tablets making them easier to swallow
  • They are used as disintegrants to facilitate the breaking down of drugs in the system during absorption.
  • They add flavor to drugs

Categories of Excipients

Excipients fall under several broad categories. There are currently over 40 functional categories of excipients in pharmaceutical products.
Arichem offers a full range of excipients including:

1. Excipients for oral dosage formulations

These are excipients used in the formulation of oral dosage drugs and include disintegrants, stabilizers, diluents, lubricants, glidants, surfactants, binders (compressible, granulation, and high-functionality), plasticizers, sweeteners, colorants, flavors, release-controlling polymers, and film-coating polymers.

Arichem stocks and distributes the following oral dosage excipients


  • Lactose Monohydrate
  • Mannitol BP
  • Magnesium Trisilicate
  • Magnesium Hydroxide
  • Magnesium Stearate
  • Magnesium Chloride Hexahydrate
  • Microcrystalline Cellulose
  • Sorbitol
  • Calcium Phosphate
  • Maize starch
  • Sodium starch Glycolate

2. Excipients for suspensions and solutions formulations

A suspension is a liquid with fine particles of a drug scattered within it in which case the drug is not fully dissolved and is visible through the suspension. Suspensions are dissolved and absorbed faster into the system compared to solid forms of dosage.

Syrups, on the other hand, are pharmaceutical solutions in which a drug is completely dissolved. Syrup excipients are used in the formulation of pharmaceutical solutions.
Suspensions are useful in the formulation of oral drugs, parenteral preparations, topical products, inhaled respiratory drugs, film-coated tablets, and suppositories.

Arichem supplies a wide range of syrup and suspension excipients including


  • Sorbitol
  • Carbomers
  • Liquid glucose
  • Microcrystalline Cellulose

3. Excipients for powder and aerosol formulations

Excipients used for pharmaceutical inhalation aerosols and dry powder inhaler formulation. Pharmaceutical aerosols are widely used for the treatment and management of symptoms for conditions like asthma and chronic bronchitis.

These formulations are dispensed through propellant-driven, dry-powder inhalers, or metered-dose inhalers.
Excipients in this case are used as carriers of active ingredients or as actives together with the active ingredients in which case they exist together to enhance the aerosol performance.

4. Topical formulation excipients
Excipients used for the formulation of topical medication aid the active ingredient to penetrate the skin. Topicals are usually formulated in liquid or solid forms and include gels, creams, and ointments.

Arichem’s topical formulation excipients portfolio includes a range of high-quality excipients for pharmaceutical drugs and cosmeceuticals that effectively enhance patient compliance towards treatment.
