Pharmaceuticals books have a wide range like medical. This book will teach you about different dosage forms and drug delivery systems. Medicines are substances other than essential dietary nutrients or ingredients that, when administered to a living organism, influence biological functions. The word “drug” is derived from the old word “drogue”, which means “dry herb”; and it has often been used interchangeably with “medicine”, “pharmaceutical product” and “pharmaceutical products” to refer to chemical substances intended to be used in the diagnosis, prevention, treatment and management of diseases in man and other animals. Traditionally, drugs were obtained naturally from minerals, plants or animals, but more recently, as by-products of microbial growth, through chemical / organic synthesis, molecular modification or biotechnology.

Before moving forward we need to understand some basics.

What Are Dosage Forms?

The term “dosage forms” refers to pharmaceutical preparations or formulations in which a specific mixture of drug substances (active pharmaceutical ingredients) and inactive components (excipients) are presented in a particular configuration to facilitate easy and precise administration and delivery of active pharmacological substances.

Why does Need for Dosage Forms:

In addition to ensuring the safe and convenient administration of the required dose of drug substances to the sites of action, dosage forms are needed for the following additional reasons:

  • To achieve a rapid onset of action after drug administration, e.g, parenteral dosage forms, inhalation / respiratory dosage forms.
  • To mask the undesirable taste or the unpleasant odour of a drug substance, for example, capsules, taste-masked suspensions, coated tablets, etc. Provide pharmaceutical products that are stable, effective and safe for consumption under specific suitable storage conditions, eg powders for reconstitution.
  • Protect drug molecules from the destructive influence of gastric juice after oral administration of the dosage form, eg enteric-coated tablets. Provide pharmaceuticals that prevent first-pass metabolism, eg injections, topical dosage forms, etc.
  • Provide medicaments with a predetermined rate and prolonged therapeutic effect over a prolonged period of time, for example, modified-release tablets, capsules, and suspensions.
  • Provide pharmaceuticals that bind to a specific physiological site of action, eg tablets, capsules, etc. targeted release. To provide a useful dosage form for administering insoluble or poorly soluble drugs in a suitable vehicle, eg, suspensions.
  • Provide sterile, clear and particle-free liquid dosage forms, for example injections and eye drops.

types of dosage form in pharma


The purpose of Pharmaceutical Dosage Forms and Drug Delivery Systems 10th Edition by Anal’s is to introduce pharmacy students to the principles, practices and technologies applied in the preparation of pharmaceutical forms and drug delivery systems. An integrated presentation is used in this textbook to demonstrate the interrelationships between pharmaceutical and biopharmaceutical principles, product design, formulation, manufacturing, composition, and clinical application of various dosage forms in patient care. The regulations and standards that govern the manufacture and composition of pharmaceutical products are also presented. As has been the hallmark of this textbook since its first edition more than 40 years ago, each chapter is written at a level consistent with the requirements of students entering this area of ​​study.

Because this tenth edition of drug delivery system textbook is often used early in the professional curriculum, it contains important introductory topics such as the historical development of drugs and pharmacy, the role of the pharmacist in contemporary practice, the Pharmacopoeia standards of the United States – National Formulary, Systems and Techniques. of pharmaceutical measurement, pharmaceutical and biopharmaceutical principles applicable to the development of pharmaceutical products, current good manufacturing practices and current standards of good compounding practices, and the regulatory process by which manufactured pharmaceutical products are approved for commercialization by the Food Administration and Federal Medications. Detailed presentation of each dosage form includes physical, physicochemical, and clinical discussions. The new activities at the end of each chapter are designed to provide opportunities for creative thinking and the application of content.

What is in this edition:

The tenth edition of Ansel’s Pharmaceutical Dosage Forms presents another significant rewrite of some of the sections of the previous edition and many updated and new figures. We have retained the eight divisions, containing 20 chapters, based upon traditional pharmaceutical pedagogy. This allows the systematic presentation of dosage forms according to their physical form and characteristics. The “Physical Pharmacy Capsules” introduced in the sixth edition continue to emphasize important underlying pharmaceutical principles. Other features that we have retained from the ninth edition include:

1. Enhanced considerations of dosage form design and formulation.
2. Two case studies (one pharmaceutical and one clinical) in each of the dosage form chapters (see “Explanation of the SOAP Format for Case Studies” later in
the preface).

3. An update of the current good compounding practices.
4. Expanded clinical considerations in the use of the dosage forms.
5. Two glossaries in the appendices, one listing the dosage forms and one listing the pharmaceutical terms.
6. Chapter objectives that inform students what they will master in each chapter.
7. An “Applying the Principles and Concepts” section at the end of each chapter
provides faculty and students with group and individual activities for the
application of the material in each chapter.

8. Information related to both manufactured and compounded dosage forms,
nonsterile and sterile, that is, quality assurance for pharmacy-prepared sterile
products: revised USP Chapter <797>. This is important because the contemporary practice of pharmacy requires the knowledge of both to effectively work
with prescribers, patients, and other pharmacists.

A drug is defined as an agent intended to be used in the diagnosis, mitigation, treatment, cure, or prevention of diseases in humans or other animals (Food, Drug, and Cosmetic Act, 1938). One of the most amazing qualities of drugs is the diversity of their actions and effects on the body. This quality allows its selective use in the treatment of a variety of common and rare conditions that affect virtually every organ, tissue and cell in the body.

Some drugs selectively stimulate the heart muscle, central nervous system, or gastrointestinal tract, while other drugs have the opposite effect. Mydriatic drugs dilate the pupil of the eye, and miotics contract or decrease the size of the pupil. Drugs can make the blood more or less cuttable; they can increase the haemoglobin content of erythrocytes, reduce serum cholesterol, or expand blood volume. Drugs called emetics to induce vomiting, while antiemetics prevent vomiting. Diuretics increase the flow of urine; expectorant drugs increase the fluid in the respiratory tract, and cathartics or laxatives evacuate the bowel. Other drugs decrease urine flow, decrease body secretions, or cause constipation. Medications can be used to reduce pain, fever, thyroid activity, rhinitis, insomnia, heartburn, motion sickness, blood pressure, and mental depression. Other medications can raise your mood, blood pressure, or endocrine gland activity. Medications can fight infectious diseases, destroy intestinal worms, or act as antidotes to the poisoning effects of other medications.

Drugs can help you stop smoking or abstinence from alcohol, or they can change obsessive-compulsive disorders. The drugs are used to treat common infections, AIDS, benign prostatic hyperplasia, cancer, cardiovascular disease, asthma, glaucoma, Alzheimer’s disease, and male impotence. They can protect against the rejection of transplanted tissues and organs and reduce the incidence of measles and mumps.

Antineoplastic drugs provide a means to attack the cancer process; radioactive pharmaceuticals provide another. Medications can be used to diagnose diabetes, liver dysfunction, tuberculosis, or pregnancy. They can replenish a body deficient in antibodies, vitamins, hormones, electrolytes, proteins, enzymes, or blood. Medications can prevent pregnancy, help fertility, and sustain life itself.
