 Ansel's Pharmaceutical Dosage Forms and Drug Delivery System, 9th Edition 2011, Ansel's Pharmaceutical Dosage Forms & Drug Delivery System, 9th Edition Related PapersLe Thi My Hanh It about basic pharmaceutiis  Denis Atkins IP Innovative Publication Pvt. Ltd. Extemporaneous compounding takes place in community and hospital pharmacies. There are usually specialist compounding pharmacies in major towns and cities, but any pharmacy may undertake compounding as long as they have appropriate facilities according to state-based legislation (e.g. allocated clean bench, specific compounding equipment). Although development is a continuous process, companies are customizing features to meet the majority of patient needs, but the very nature of the process cannot meet all patient needs. The risk-benefit ratio of using traditionally compounded medicines is favorable for patients who require specialized medications that are not commercially available, as they would otherwise not have access to suitable treatment. However, if an FDA-approved drug is commercially available, the use of an unapproved compounded drug confers additional risk with no commensurate benefit. Published reports of independent testing by the FDA, state agencies, and others consistently show that compounded drugs fail to meet specifications at a considerably higher rate than FDA-approved drugs. Compounded sterile preparations pose the additional risk of microbial contamination to patients. In the last 11 years, three separate meningitis outbreaks have been traced to purportedly ‘sterile’ steroid injections contaminated with fungus or bacteria, which were made by compounding pharmacies. The 2012 outbreak has resulted in intense scrutiny of pharmacy compounding practices and increased recognition of the need to ensure that compounding is limited to appropriate circumstances. Purpose of the Study: The article aims to physico-chemical and economic considerations before compounding; factors and quality control issues; compounding support, training, chemical supplies, types of compounding (specially in hospital and ambulatory care compounding). It should aid to practice the extemporaneous preparation of basic and advanced formulations including pharmacopoeial and non-pharmacopoeial formulations encountered in pharmacy practice, together with requisite documentation, labeling, packaging and counseling requirements. Along with this, they have to study the analysis of formulations and their components and relate these to the clinical performance of medicines. This will help them to investigate, evaluate and report the physical characteristics of formulations including release kinetics and relate these to quality control and preformulation requirements; relate the application of quality control, quality assurance and the principles of good manufacturing practice to regulation of medicine production in home and abroad.

Indian J Pharm Educ Res Harish Nairy , Kulkarni Sir , Mohammed Gulzar Ahmed Dr.Rakesh K Sharma Giriraj Kulkarni Mohammed Gulzar Ahmed , Kulkarni Sir A gastro retentive floating controlled drug delivery system containing glipizide was prepared in the form of tablet and evaluated for its processing parameters and in- vitro release behaviour as per United States Pharmacopoeia in pH 1.5 buffer. Ten formulations containing retardant materials such as HPMC4K and eudragit RS100, alkalizing agent sodium bicarbonate and other release promoters such as sodium lauryl sulphate and polyvinyl pyrrolidone were used. Tablets remained buoyant over 8 hours in the release medium, and the amount of sod. bicarbonate found to be significant for not only to remaining buoyant without causing disintegration of the tablet, but also to release of drug in the acidic medium. The ratios employed for the retardant materials did not show much significant difference in the release. However the solubilizing agent, PVP, amount found to be significant as far as the release of the drug is concerned. Further the selected best formulations were compared with the marketed sustained release product and found to be comparable release of the drug. Stability study for the selected formulations was conducted for a period of two months at 25oC and 40oC respectively and the formulations exhibited no alteration in the physical appearance or content of the tablet. All the formulations exhibited diffusion dominated drug release. Finally the tablet formulations found to be economical and may overcome the draw backs associated with the drug during its absorption.

Why are dosage forms needed? Extended functions of dosage forms What is a “route of drug administration”? Why are different routes of drug administration needed? What is the ideal in drug delivery and why is this ideal not easy to achieve? Overview of common routes of drug administration Chapter 1 deals with the approach that this book takes to the study of pharmaceutics. It makes the point that the drug and its dosage form must be considered together. The dosage form may significantly alter the impact of the drug and, in certain instances, actually change the nature of the observed pharmacological response. Several examples were given to explain the expanded role of the dosage form, illustrating the modified effects obtained as a consequence of the drug being placed within specialized dosage forms. This chapter starts off with a discussion of dosage forms to illustrate why we need them from a practical point of view, even when they do not materially affect the pharmacological response. It then briefly describes the different routes of drug administration. These two topics serve as the prelude to a book that deals largely with dosage forms and routes of drug administration ( Mind Map 2-1 ). MIND MAP 2-1Some Dosage Forms and Their Most Important Routes of Administration  With respect to dosage forms, the following aspects are important: What they are Why we need them What goes into them (ingredients) How they are made How they are tested What effect they have on the body (biological system) How the body affects them Their stability The advantages and disadvantages of each type How to choose from the different types of dosage forms, of the same drug, for a particular patient In addition, the mechanisms of drug release from the dosage form are important, as are the mechanisms and physiological factors that affect its absorption. A general approach adopted in this book is to outline the principles and give a few examples for illustrative purposes. Given that the book takes this approach, it is useful to start with a very basic concept: what are dosage forms and why do we need them?

Drugs are rarely administered as pure chemical entity, Almost always given as formulated preparations i.e Dosage form . They are administered in the different dosage forms after converting them into a suitable dosage formulation. Drug substances are seldom administered alone; rather they are given as part of a formulation in combination with one or more nonmedicinal agents (referred to as pharmaceutical ingredients or excipients ) produce dosage forms of various types. The pharmaceutical ingredients solubilize, suspend, thicken, dilute, emulsify, stabilize, preserve, color, flavor, and fashion medicinal agents into efficacious and appealing dosage forms. The potent nature of most active drug substances and their low dose requirement which may not be convenient to weigh on routine bases as required by patients has prevented their use in the treatment and management of disease conditions. In other to obtain a stable, elegant, safe and therapeutic active drug product, drug substances are formulated into appropriate dosage forms ; each designed to contain a given quantity of active drug substances for ease and accuracy of dosage administration. What is A DrugThe word “ drug ” is derived from the old French word “ drogue ” which means a “dry herb”; and has often been used interchangeably with “medicine”,. “ Pharmaceutical product ” and “ pharmaceuticals ” to refer to chemical substances intended for use in the diagnosis, prevention, treatment and management of disease(s) in man and in 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. Dosage form & need for the Dosage formDrugs are rarely administered as pure chemical entity, Almost always given as formulated preparations. They are administered in the different dosage form after converting then into a suitable dosage formulation. Dosage forms are the means by which strong molecules/drugs are delivered to desired site of action within the body. 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 accurate administration and delivery of active drug substances. Or You can say The manner in which drug substance are presented in the market. (Solid, Liquid or Gaseous) Desirable properties of dosage form should:

 Formulation of medicines for children1 Clinical Director of Pharmacy, Royal Liverpool Children's NHS Trust, Liverpool, UK Julie Williams2 Pfizer Global Research & Development, Sandwich, UK The development of age-adapted dosage forms and taste-masking of bitter-tasting drugs administered orally for children, are formidable challenges for formulation scientists. Childhood is a period of maturation requiring knowledge of developmental pharmacology to establish dose but the ability of the child to manage different dosage forms and devices also changes. Paediatric formulations must allow accurate administration of the dose to children of widely varying age and weight. Whilst the oral route will be preferred for long term use and the intravenous route for the acutely ill, many of the dosage forms designed for adults, such as oro-dispersible tablets, buccal gels and transdermal patches, would also benefit children if they contained an appropriate paediatric dose. The age at which children can swallow conventional tablets is of great importance for their safety. Liquid medicines are usually recommended for infants and younger dhildren so the ability to mask unpleasant taste with sweeteners and flavours is crucial. More sophisticated formulations such as granules and oro-dispersible tablets may be required but there will be limitations on choice and concentration of excipients. There are many gaps in our knowledge about paediatric formulations and many challenges for the industry if suitable preparations are to be available for all ranges. A CHMP points to consider document is soon to be released. More research and clinical feedback are important because a formulation with poor acceptability may affect compliance, prescribing practice and ultimately commercial viability. IntroductionIn pharmacology and clinical paediatrics the focus is on the active drug substance (or active pharmaceutical ingredient (API)) when determining dosage, clinical effects and adverse drug reactions. However, the formulation is fundamentally important since it determines, in practice, whether the dose can be successfully delivered to the paediatric patient. Moreover, it is important to consider the formulation excipients and the potential for any adverse effects in this potentially vulnerable age group. The development of formulations which are appropriate for children can present significant challenges to the pharmaceutical scientist. Unlike in adults, where oral solid dosage forms such as tablets or capsules will be acceptable to the majority of patients, potential paediatric patients may include neonates, newborn, toddlers, young children and adolescents, and as such, will have widely varying needs. The development of multiple dosage forms for different ages will rarely be commercially viable and liquid formulations, which can be given to a broad age group, present particular pharmaceutical challenges. For example, taste masking a bitter-tasting drug is a major formulation hurdle which can be very costly and may not be totally achievable. Some considerations for the development of acceptable paediatric drug formulations are discussed below. Requirement for dosage formsThere are various reasons for the formulation of drugs into appropriate dosage forms; one of the most important relates to accurate measurement of the dose. Many active drugs are very potent and only require milligram or microgram amounts to be administered. For children the amount of drug required for the dose varies with age and weight. Active drugs must be diluted in a vehicle which allows accurate and convenient dose measurement. Active drugs must also be protected during their shelf life from degradation, for example by oxygen and humidity and, when administered orally, may require protection from degradation by gastric acid. It may be necessary to conceal taste and smell and to produce liquid preparations of insoluble or unstable drugs. There may be a requirement for rate controlled action or optimization of delivery of topical or inhalational drugs and those delivered by injection must be sterilized. Ages and abilitiesChildhood is characterized by periods of rapid growth, maturation and development. The ability to handle active drugs changes during childhood and is recognized in developmental pharmacology. There is a change in the magnitude of dose required during childhood and adolescence which may be fifty-fold. There are also significant changes in the ability to handle different dosage forms with small volume liquid medicines being appropriate for oral use in the younger age groups; liquid medicines and fast dissolving ‘melt’ formulations suitable for most ages and tablets and capsules being more convenient to the lifestyle of adolescents. Paediatric practice requires a range of dosage forms that are acceptable at different ages and abilities and a range of strengths or concentrations allowing administration of the correct age-related dose. Seriously ill children will require intravenous drug administration and will prefer this to frequent intramuscular injections. For less serious illness and long-term administration the oral route will be preferred but other routes such as buccal, nasal, transdermal and rectal can be useful in some circumstances. The age at which children take tablets or capsules is a factor of importance to their safety so that inadvertent inhalation and choking are avoided but is also of great importance to manufacturers. Tablet formulations are generally easier and cheaper to develop, manufacture, transport, store and dispense than liquid medicines. There is little information in the literature but it is generally believed that traditional tablets may be accepted by children of school age, although this will depend on the size and shape of the tablet and patient factors such as the taste of liquid medicine alternatives. In fact, advances in pharmaceutical technology have resulted in the development of many different types of tablets such as melts, chewable and oro-dispersible tablets, and it is technically possible that appropriate tablet formulations could be made available for children of most ages, but at a cost. Challenges with oral liquid formulationsThe dose and volume of liquid medicines may be limited by the solubility of drug substances requiring the addition of cosolvent and surfactant excipients. Physical, chemical and microbiological stability must be assured with buffering agents, antioxidants and preservatives. Of crucial importance is the ability to mask unpleasant taste with sweeteners and flavours. If this is not achievable, more sophisticated formulation approaches such as encapsulation of drug particles, may be required. These more complex formulation approaches bring higher technical challenges and consequently, research and development will be more lengthy and costly. Formulation homogeneity is required and dosing devices such as droppers or syringes may be required for accurate dosing. There are limitations on choice and concentration of excipients for paediatric patients. Solid dosage formsA wide variety of solid dosage forms is now available including powders (e.g. Viracept® oral powder (nelfinavir mesylate, Pfizer), granules (e.g. Singulair® oral granule (Montelukast Na, Merck) and sprinkles (e.g. Depakote® Sprinkle capsules (Divalproex Na, Abbott). These are usually mixed with specified food or drink and are easy to swallow. Taste is again important; there is risk of incomplete ingestion and consequently a reduction in the dose given. Potential for technical challenges include powder processing, packaging, stability and dose extraction. A variety of modern tablet preparations is available such as fast dispersing dosage forms (FDDFs), for example Calpol Fast Melts® (Pfizer Consumer Health), Nurofen® Meltlets (Crookes Healthcare), Benadryl® orodispersible tablets. None of the products currently has a licence for children less than 6 years of age, primarily due to the dose strengths available. These products are placed in the mouth where they ‘melt’ on the tongue in a small amount of saliva or can be dispersed in a small amount of liquid on a spoon. They are easy to administer providing that taste is acceptable and they provide accuracy of dose. However, many of these technologies are proprietary and consequently will require licensing agreements Development costs are higher than for conventional oral dosage forms. Examples include Zydis™ (Scherer), OralSolv™ (Cima), WOWtab™ (Yamanouchi), Films (LTS Lohman) Tan and Cranswick NE (2003) have shown that in Australia 70–80% of products suitable for children have inadequate dosing information in the SPC and that in 25% of products licensed for children, dosage forms are unsuitable for the intended ages. However, if there is the commercial incentive of a large market for a common illness such as pain or vomiting or for OTC products, a complete and varied portfolio of products can be made available as shown by paracetamol and ondansetron. An ideal formulation for children will allow minimal dosage and frequency; will have one dosage form to fit all or a full range; will have minimal impact on lifestyle; a minimum of nontoxic excipients and will have convenient, easy, reliable administration. It should also be easily produced, elegant, stable, cheap and commercially viable. The challenge in achieving this should not be underestimated. Challenges and knowledge gapsThere are many gaps in our knowledge about paediatric formulations and many challenges for industry to face if suitable preparations are to be available for all age ranges. These include
Information is available with a CHMP points to consider formulation document in draft. Undoubtedly more research and clinical feedback will be valuable since if a formulation has poor patient acceptability, it affects compliance, prescribing practices and ultimately commercial viability. ConclusionsDetermining the correct dose and our ability to deliver it to the child successfully are equally important. We need a variety of different dosage forms to satisfy clinical need, varying dose requirement with age; ability and preference. The availability of appropriate dosage forms is limited even when the medicine is authorized for children. EU regulations and incentives may improve the situation from 2007 and a points to consider document on ‘formulations of choice for the paediatric population’ should better inform the industry. We need to encourage and work with manufacturers to adapt medicines to the needs of children but should also ensure that pharmacists and carers have information to adapt dosage forms safely and to extemporaneously formulate if necessary. Clearly more research and development is required. |
