While selecting the additives ,care must be taken that they should be compatible both physical and chemical with the entire formulation.
They should meet the pharmaceutical quality standards as described in pharmacopeias and ICH guidelines and also ensure the clinical tolerance as well as to be safe for the intended purpose of use. The excess use of adjuvants in parenteral products should be avoided as some of these may interfere with the drug.
Pagenterals agents are compounds that can form formylation with metal ions, and in so doing inactivate the catalytic activity of the metal ions in the oxidation process. Mineral oils cannot be used as they are not absorbed by body tissues. The main challenge of all the different parenteral dosage forms is to achieve a good compatibility of the drug substances with the excipients no formation of new impurities either by degradation of the drug substance or formation of new chemical entity between the drug substance and the excipients as well as the compatibility of the preparations with the primary container no leachable or adsorption to container.
Antioxidants can be classified as:.

Raw Materials Used in Parenterals Formulation |authorSTREAM
The stabilizers are added in the formulation to prevent this. In order to view it, please contact the author of the presentation. Drug formulated into injectable suspensions because: Parenteraos to protect drug against loss of activity caused by stress that is introduced by manufacturing process.
The pH is one of the critical aspects of parenteral preparations which should have a pH close to the physiological one.
In the preparation parenteraos parental productsthe following substances are added to make a stable preparation. Finally the process of the sterilization should be selected according to the characteristics of the parenteral preparations for instance, heat steam sterilization for aqueous solutions and dry heat for non-aqueous solutionsbut in any parebterals it can be justified by the nature of the primary containers.
In all cases, large volume preparations LVP, i. Keep up with our latest articles, news and events.
They are added to protect components of the dosage form, which are subject to chemical degradation by oxidation. Parenteral preparations are intended pwrenterals be administrated through the human or animal body, either by direct injections for example, bolus intravenous IVintramuscular IM or subcutaneous SC or by infusion with a controlled infusion rate or by direct implantation through IM or SC.

Roquette has developed a pyrogen-free range of products with high pharmaceutical standards and being biocompatible for the manufacture of parenteral preparations, All these pyrogenfree range of products are obtained from natural and renewable raw materials. Prepared by following methods: Metal ions enhance the oxidation process ,hence these are to be turned off by chelating agents.
With regards to solutions and emulsions, the drug substances should be soluble and remain soluble during the entire shelf-life of the drug products. Parenteral preparations are defined as solutions, suspensions, emulsions for injection or infusion, powders for injection or infusion, gels for injection and formulaation. Modified by preparing estersalt or some other derivative in order to: As most drugs are weak acids and bases.
