Students or readers must consult their physician about any existing problem. pharmaceutics, pharmaceutical chemistry and biopharmaceutics. This review presents considerations which can be employed during the development of a semi-solid topical generic product. 1371.2 Equivalence of Topical Products 138 Demonstration of equivalence of a new topical medicinal product with an existing medicinal product 139 may be required in the context of marketing authorisation applications relying on the dossier of an Reference Guide For Pharmaceutical Calculations Krisman www.pharmacyexam.com 2 This reference guide is not intended as a substitute for the advice of a physician. Typically, medicated ointments are used for the treatment of infection, inflammation and

the rectum, the vagina/vulva, the eye. Due to the interdisciplinary nature, Compare and contrast the advantages/disadvantages of various drug List reasons for the incorporation of drugs into various dosage forms 2. Predicting Performance of Pharmaceutical Lotions Through Rheological Characterization Keywords: cosmetics, pharmaceutical, oscillatory testing, flow testing, creep, creep-recovery, sensory panel PROBLEM A pharmaceutical company wanted to compare the “spreadability” of two lotions to determine the effects of formulation differences. Dosage Form Design: Pharmaceutical and Formulation Considerations 4 SECTION II DRUG DOSAGE FORM AND DRUG DELIVERY SYSTEM DESIGN After reading this chapter, the student will be able to: 1. introduction of a material for marketing as an excipient to the pharmaceutical industry as well as to indicate the steps used to establish the requirements for use of an excipient by a pharmaceutical company. Rheology is an Accurate Predictor of Pharmaceutical Lotion Stability Keywords: emulsion stability, shelf-life prediction PROBLEM Many pharmaceutical lotions are small particle suspensions where shelf life is determined by the particle settling rate on standing. Pharmaceutical formulation may therefore be correctly viewed as an essential and unique component of the pharmaceutical sciences and, accordingly, the Pharmacy undergraduate degree.

1.2 Scope This guide is applicable to all excipients used in pharmaceutical dosage forms. Pharmaceutical lotions and suspensions, often used to treat rashes and skin irritations, are typically produced using the same high-standard process conditions and equipment as sterile products. 1.3 Principles Adopted 1 Pharmaceutical ointments and pastes General description Pharmaceutical ointments are semisolid systems that are applied externally, primarily to the skin and also to mucous membranes, e.g.

This includes a discussion on the implementation of quality by design concepts during development to ensure the generic drug product has similar desired quality attributes to the reference-listed drug (RLD) and ensure batch to batch consistency through commercial production.
