How to Choose the Right Preservative for Your Drug Product: A blog about how preservatives work, and what are the types in pharmaceuticals.

For quite a few years drug specialist have known about the need to secure their items against microbial pollution yet it is just during the final remaining one or maybe twenty years the genuine considered has been

applied to the study of safeguarding pharmaceutical products. The health care industry has experienced an explosion in the past several decades in terms of patient numbers and coverage. As a result more drugs are being created with preservatives and other additives to improve quality and patient safety.

Pharmaceutical companies are constantly looking for ways to prevent product degradation and therefore prevent potential drug interactions. Preservatives are one potential approach they may take. They are designed to block the breakdown of a substance that is critical to a particular medication’s metabolism.

Preservatives play a niche role in the pharmaceutical industry and are used in small quantities to inhibit microbial activity in order to increase drug potency, lengthen shelf-life and maintain stability. They preserve the original properties of a drug product for as long as possible during storage. By preventing molds and bacteria from growing within the medicine, preservatives keep the drug fresh and at its highest quality until it is ready to be administered. There are many different types of preservatives and each has its own place in the drug.

In this article, we'll explore the different types of preservatives commonly found in medicines and pharmaceuticals.
We'll look at how they help prevent microbial contamination so that medicines can be safely consumed.

Preservatives have been used in the manufacture of drugs to prevent the microbial growth and toxigenesis. Their selection is based on six factors, namely toxicity, efficacy data, physicochemical properties and comparative and cost-benefit evaluations. Preservative selection should be done by considering all these factors.

Due to the emergence of antibiotic resistance, there has been a paradigm shift from conventional antibiotics to use of preservatives in different drug formulations.

In recent years, some groups have focused their attention on non-pharmaceutical applications of preservatives, particularly in food industry products such as bakery goods and prepared foods. Industry experts continue to emphasize the importance of using good microbiological practices.

Security of Preservatives in Medicine and Pharmaceuticals:

Additives in medications and medications are by and large viewed as "latent fixings" by FDA. Inert fixings (like colors, additives, and seasoning specialists) are portions of a medication or medication that don't influence the restorative activity of the dynamic fixings. FDA's Inactive Ingredient Database gives data on idle fixings present in FDA-endorsed drug items.

FDA, the Centers for Disease Control and Prevention (CDC), the National Institutes of Health (NIH) and other government organizations consistently screen and direct examination on immunization security.


Certain cycles like freezing, pickling, smoking and salting can likewise be utilized to protect food. Another gathering of additives targets chemicals in products of the soil that keep on processing after they are cut. For example, citrus and ascorbic acids from lemon or other citrus juice can restrain the activity of the catalyst phenolase which turns surfaces of cut apples and potatoes earthy colored. Alert should be taken, in any case, since FDA norms don't at present require foods grown from the ground item names to precisely mirror the sort of additive utilized in the items.

  1. Antimicrobial specialist:- The specialist which dynamic against gram positive and gram negative miniature creature which causes debasement of drug arrangement. Which are dynamic in little incorporation level. Which acting by cell divider restraint, protein union hindrance, DNA &RNA union restraint.

    Examples include Benzoates, Sodium benzoate, Sorbates, Propionates, Nitrites
  2. Antioxidants: Antioxidants are chemical agents that prevent or delay the oxidative degradation of products. Antioxidants therefore, protect the quality and stability of a medicine. Antioxidants are often referred to as they prevent or reduce oxidation. Antioxidants should be used in combination with the other 3 essential parameters of drug stability; temperature, pH and water activity to minimize the chances of oxidative effects occurring like hydrolysis, reduction and oxidation reactions.

    Examples of antioxidants that has been used in such products are Vitamin C, Butylated- hydroxyanisole (BHA), Butylated-hydroxytoluene (BHT), et cetera.
  3. Chelating agent: Which forming a complex with pharmaceutical ingredients and prevent the degradation of formulation.

    Examples:- Disodium ethylenediamine tetra-acetic acid (EDTA), Polyphosphates, Citric acid.

The compound citric acid is an excellent choice for use as a preservative in your medicines. This preservative is heavily used in the pharmaceutical industry for preventing the growth of mold, bacteria, and fungi. It has a wide range of applications including wounds, cosmetics, dental care preparations, insecticides and fungicides, toys and agricultural products. The benefits of using citric acid as a preservative include reduced side effects, such as headaches and dizziness in some cases. It also has anti-inflammatory properties which can help with joint pain and swelling when taken regularly.

Our citric acid anhydrous is a pharmaceutical grade preservative which acts as a virucide and broad-spectrum bactericide. It is used in liquid and powder formulations of topical, ophthalmic, or otic pharmaceuticals; sterile suspensions and sustained-release systems for drug delivery; emulsions for buccal and nasal delivery; cosmetics; food additives; beverages; pH control agents; and as an antioxidant. It is also used as an acidulant to increase the acidity of foodstuff and beverages (acidification).
