Metal ions enhance fprmulation oxidation process ,hence these are to be turned off by chelating agents. Unstable drug substances will lead to the formation of new impurities jeopardizing the safety of use of the preparations. They can stabilize proteins both in solution as well as dry state. Alcohol causes pain and tissue damage at the site of injection.

Chelating agents are compounds that can form complexes with metal ions, and in so doing inactivate the catalytic activity of the metal ions in the oxidation process. They are added to protect components of the dosage form, which are subject to chemical degradation by oxidation. Automatically changes to Formklation or non-Flash embed.

Parenteral Preparations, Challenges in Formulations

Oarenterals by following methods: They are required, like any pharmaceutical dosage formsto meet the pharmaceutical quality standards as described in pharma-copeias and to be safe for the intended purpose of use. The stabilizers are added in the formulation to prevent this. To make the formulation isotonic. Study material for Pharma students updated their status.

Parenteral Preparations, Challenges in Formulations. So, buffers are used to adjust and maintain pH in order to increase stability, solubility, absorption and activity of API. It is done because osmotic pressure changes and resultant exchange of ionic species across RBC membrane causes many problems.


They are subject to partial ionization under a given pH. Phenytoin sodium injection contains phenytoin that is solubilized in the water miscible solvent at pH 12 and if it is added to large volumethen precipitation occurs.

Therefore pxrenterals is not used commonly. Formulation of parenteral preparations the formulation of parenteral preparations need careful planning ,thorough knowledge of medicaments and adjuvants to be used.

Used to protect drug against loss of activity caused by stress that foemulation introduced by manufacturing process. The efficiency of the selected sterilization process should be demon-strated through validation studies, using the appropriate biological indicators, to ensure an ASL Assurance Sterility level of 10 Parenteral preparations may require the use of excipients that should be biocompatible, be selected for the appropriate use and to be included at the minimum efficient concentration.

Used to prevent degradation and denaturation of injectable protein formulations such as insulin.

Metal ions enhance the oxidation process ,hence these are to be turned off by chelating agents Parentterals Presentation: Pharma recruitment news Dormulation Website. Elham Blouet, Pharmacist with several years of experience in industrial pharma companies and health authorities agency.

In the preparation of parental productsthe following substances are added to make a stable preparation. Pharmacology Notes Education Website.

The stability of the drug substance is another critical point that a formulator can face during the development of the formulation.

Sections of this page. When drug substances are not soluble, dissolution can be achieved by the use of co-solvents, surfactants, or a soluble pro-drug, or eventually the use of solubility enhancers such as cyclodextrins thanks to the formation of inclusion complex.

In order to view it, please contact the author of the presentation. Chemistry Masala Personal Blog.

Fixed vegetable oils are used Prolong drug release at site of administration can be achieved when converted to oily suspension. Antioxidants can be classified as: Fixed oil, such as, arachis oil,cottonseed oil ,almond oil and sesame oil are used as vehicle. WordPress Embed Customize Embed.


In order to decrease drug solubility for improving its stabilitywe can: 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.

When these are formulatiin as vehicles,then formulations should not be diluted with water as precipitation may occur. The aqueous vehicle used are formuulation 1 water for injections. Antioxidants prevent or inhibit oxidation of drug. Ethyl alcohol is used in the preparation of hydrocortisone injection. B Non -aqueous vehicles: These are contrast media having radioactive iodine, chromium, technetium, iron etc meant for evaluation of organ functions. You do not have the permission to view this presentation.

The pH is one of the critical aspects of formulattion preparations which should have a pH close to the physiological one.

They should meet the pharmaceutical quality standards as described in pharmacopeias and ICH guidelines and also parrnterals the clinical tolerance as well as to be safe for the intended purpose of use.

Raw Materials Used in Parenterals Formulation |authorSTREAM

These are sub visible particles. To disperse a water insoluble drug as a colloidal dispersion For wetting powders For better syringe ability Prevent crystal growth in suspensions For solubilizing steroids and fat soluble vitamins. Plus, get special offers and more padenterals to your inbox. Includes drugs in solution, suspension, gel or ointment meant for administration in to the corneal surface of the eye.

Mineral oils cannot be used as they are not absorbed by body tissues.
