Regulatory Challenges

Osteoarthritis (OA), a common musculoskeletal disorder, is projected to affect about 60 million people of total world population by 2020. The associated pain and disability impair the quality of life and also pose economic burden to the patient. Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely prescribed in OA, while diclofenac is the most prescribed one. Oral NSAIDs are not very patient friendly, as they cause various gastrointestinal adverse effects like bleeding, ulceration, and perforation. To enhance the tolerability of diclofenac and decrease the common side effects, aceclofenac (ACE) was developed by its chemical modification. As expected, ACE is more well-tolerated than diclofenac and possesses superior efficacy but is not completely devoid of the NSAID-tagged side effects. A series of chemical modifications of already planned drug is unjustified as it consumes quanta of time, efforts, and money, and this approach will also pose stringent regulatory challenges. Therefore, it is justified to deliver ACE employing tools of drug delivery and nanotechnology to refine its safety profile. The present review highlights the constraints related to the topical delivery of ACE and the various attempts made so far for the safe and effective topical delivery employing the novel materials and methods.

Experience Difficulty

Oral route is presently the gold standard in the pharmaceutical industry where it is regarded as the safest, most economical and most convenient method of drug delivery resulting in highest patient compliance. Over the past three decades, orally disintegrating tablets (FDTs) have gained considerable attention due to patient compliance. Usually, elderly people experience difficulty in swallowing the conventional dosage forms like tablets, capsules, solutions and suspensions because of tremors of extremities and dysphagia. In some cases such as motion sickness, sudden episodes of allergic attack or coughing, and an unavailability of water, swallowing conventional tablets may be difficult. One such problem can be solved in the novel drug delivery system by formulating “Fast dissolving tablets” (FDTs) which disintegrates or dissolves rapidly without water within few seconds in the mouth due to the action of superdisintegrant or maximizing pore structure in the formulation. The review describes the various formulation aspects, superdisintegrants employed and technologies developed for FDTs, along with various excipients, evaluation tests, marketed formulation and drugs used in this research area.

Microparticles, microspheres, and microcapsules are widely used constituents of multiparticulate drug delivery systems, offering both therapeutic and technological advantages. Microparticles are generally in the 1–1000 µm size range, serve as multiunit drug delivery systems with well-defined physiological and pharmacokinetic benefits in order to improve the effectiveness, tolerability, and patient compliance. This paper reviews their evolution, significance, and formulation factors (excipients and procedures), as well as their most important practical applications (inhaled insulin, liposomal preparations). The article presents the most important structures of microparticles (microspheres, microcapsules, coated pellets, etc.), interpreted with microscopic images too. The most significant production processes (spray drying, extrusion, coacervation, freeze-drying, microfluidics), the drug release mechanisms, and the commonly used excipients, the characterization, and the novel drug delivery systems (microbubbles, microsponges), as well as the preparations used in therapy are discussed in detail.

Novel Drug Delivery Systems are one of the widely use delivery system in the presence scenario. Novel drug delivery system is a novel approach to drug delivery that addresses the limitations of the traditional drug delivery systems. In the form of a Novel Drug Delivery System an existing drug molecule can get a new life. The novel drug delivery system is Increases bioavailability and it Can be used for long-term treatments of chronic illness, Sustained maintenance of plasma drug levels as well as it Decreased adverse drug effects in the total amount of drugs required thus reducing side effects it Improved patient compliance due to reduction in number and frequency of doses required. There is less damage sustained by normal tissue due to targeted drug delivery. In this paper our main focus to give the throughout knowledge of some newer (Novel drug delivery system) to understand the concept of the Novel dossage form.

This chapter deals with the applications of gold nanoparticle in cancer and various strategies to target cancer cells by using gold nanoparticles. They are in great demand for biomedical applications such as DNA/Protein detection, bimolecular regulators, cell imaging and cancer cell diagnostics. The ability to tune the surface of the particle provides access to cell –specific targeting and controlled drug release. Depending on their size, shape, degree of aggregation, and local environment, gold nanoparticles can appear red, blue, or other colors. The novel drug delivery systems offer the opportunity to improve poor solubility, limited stability, bio distribution, and pharmacokinetics of drug as well as offering the potential ability to target specific tissues and cell types. The multifunctional gold nanoparticles are attractive organic –inorganic hybrid material composed of an inorganic metallic gold core surrounded by an organic or bimolecular monolayer they provide desirable attributes for the creation of drug delivery in cancer.

The present study examined the pattern of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) in relation to the source of advice. Ten community pharmacies in the United Arab Emirates were randomly selected and patients visiting these sites were interviewed using a standard questionnaire. The interview covered “source of advice,” “name of medicine,” “type of disease,” “duration of disease,” and “knowledge of adverse effects and drug interactions.” After a month the patients were contacted. On average 22.7% of prescriptions contained NSAIDs and 17.5% of visits were for these drugs. Advice from physicians was given to 33.3%, from pharmacists 32.5%, from friends 18.8%, and 15.4% depended on themselves. Other medicines were taken by 14.5% and 12% suffered from gastrointestinal upsets. Paracetamol followed by ibuprofen and diclofenac were the most frequently utilized agents. Headache, fever, and musculoskeletal pain were the common complaints. A month later, 50.7% of the patients continued taking their medications. This study revealed an association between the source of advice and knowledge of side effects. It is argued that, although self-care is important, professional advice in its support is essential since unsupervised self-medication exposes the patient to harmful consequences.

: Atopic dermatitis is a chronic inflammatory disease of the skin, which is characterized by itching, erythema and eczematous lacerations. It affects about 10 % of adults and approximately 15-20 % of children in the worldwide. As a result of genetic, immunologic and environmental factors, the disease manifests itself with impaired stratum corneum barrier and then immunological responses. Topical administration of corticosteroids and calcineurin inhibitors are currently used as the first strategy in the management of disease. However, they have low skin bioavailability and some side effects. The nano-carriers as novel drug delivery systems could overcome limitations of conventional dosage forms, owing to increment of poorly soluble drug' solubility, then its thermodynamic activity and consequently its skin permeation. Also, side effects of the drug substances on the skin could be reduced by the nano sized drug delivery systems, due to encapsulation of the drug in the nano-carriers and targeted drug delivery of drug substances to the inflammated skin areas. Thereby, there have been available a numerous of research studies and patents regarding use of the nano-carriers in the management of atopic dermatitis. This review focuses on the mechanism of disease and, developments on the nano-carrier based on novel drug release systems of in the management of atopic dermatitis.
