ReplyDeleteIt gives us great delight and Pleasure to present to pharmacy students our book entitled “Pharmaceutics-I Theory and Practical “. Writing a book is inspiring, often exciting, and sometimes very challenging work.
Pharmaceutics plays a vital role in formulation development and evaluation of various dosage forms. This book will mainly guide students to get knowledge about origin and scope of pharmacy, various pharmacopoeias, prescription and drug incompatibilities, conventional dosage forms, pharmaceutical calculation and basics of Pharmaceutics. All the contents are discussed in detail and suitable examples are explained whenever required.
The intention of this book is mainly to emphasis the importance of formulation and the approach is essentially to focus on specific dosage forms such as tablets, capsules and liquids.
