What are different types of parenteral preparation? Parenteral formulations are intended to be administered as an injection or infusion. Parenteral preparations include solutions, suspensions, emulsions, powders, and gels. The parenteral preparations should be free from all types of micro – organisms. An aseptic conditions are required to be maintained during the preparation of parenteral products and its administration. The parenteral product must pass the test of sterility. To ensure patient safety, parenteral or injectable drug products must be sterilised to destroy any potential microbial contaminants (fungi, bacteria). The most common sterilisation method involves heating under pressure in the presence of water to generate steam; this method is recommended by various pharmacopoeias. All the parenteral preparations which are supplied in sterile form must confirm to the test for sterility as prescribed in the pharmacopoeia. The test for sterility is done by detecting the presence of viable forms of bacteria ,fungi and yeast in parenteral preparations.
