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.

The oral route is a popular and convenient means of drug delivery. However, despite its advantages, it also has challenges. Many drugs are not suitable for oral delivery due to: first pass metabolism; less than ideal properties; and side-effects of treatment. Additionally, oral delivery relies heavily on patient compliance. Implantable drug delivery devices are an alternative system that can achieve effective delivery with lower drug concentrations, and as a result, minimise side-effects whilst increasing patient compliance. This article gives an overview of classification of these drug delivery devices; the mechanism of drug release; the materials used for manufacture; the various methods of manufacture; and examples of clinical applications of implantable drug delivery devices.

The aim of our research work was to isolate a biomaterial from Colocasia. esculenta and prepare phenytoin loaded mucoadhesive biofilms using this biomaterial. The biomaterial was isolated from C. esculenta tubers by an economical process. The isolated biomaterial was subjected to various physical evaluation, chemical tests as well as spectral analysis. The drug-biomaterial interaction study was performed to see if there was any interaction of biomaterial with phenytoin. Phenytoin loaded biofilms were prepared using biomaterial, flexicizer and other co- processing agents. The prepared biofilms were evaluated for physical appearance, weight, thickness, folding endurance, swelling index, surface pH, tensile strength, percent elongation, percent moisture uptake, percent moisture loss, vapor transmission rate and content uniformity. The mucoadhesivity of biofilms was investigated using rotating basket method. The in-vitro drug release study of biofilms was performed on static MS diffusion apparatus. The stability studies of biofilms were carried out at different conditions of temperature and relative humidity. The results were compared with the standard hydroxy propyl methyl cellulose (HPMC) and sodium carboxymethyl cellulose (Sodium CMC) films. The experimental results revealed that the phenytoin loaded biofilms of C. esculenta possessed excellent mucoadhesivity, sufficient stability as well as appreciable release characteristics. The best biofilm formulation was PK6 with a cumulative drug release of 95.35 % over 36 hours. Hence, C. esculenta biomaterial can serve as a potential film forming agent for transmucosal drug delivery systems.Dhaka Univ. J. Pharm. Sci. 15(2): 177-186, 2016 (December)

Polymer nanofibers have exceptionally high surface area. This is advantageous compared to bulk polymeric structures, as nanofibrils increase the area over which materials can be transported into and out of a system, via diffusion and active transport. On the other hand, since hydrogels possess a degree of flexibility very similar to natural tissue, due to their significant water content, hydrogels made from natural or biodegradable macromolecular systems can even be injectable into the human body. Due to unique interactions with water, hydrogel transport properties can be easily modified and tailored. As a result, combining nanofibers with hydrogels would truly advance biomedical applications of hydrogels, particularly in the area of sustained drug delivery. In fact, certain nanofiber networks can be transformed into hydrogels directly without the need for a hydrogel enclosure. This review discusses recent advances in the fabrication and application of biomedical nanofiber hydrogels with a strong emphasis on drug release. Most of the drug release studies and recent advances have so far focused on self-gelling nanofiber systems made from peptides or other natural proteins loaded with cancer drugs. Secondly, polysaccharide nanofiber hydrogels are being investigated, and thirdly, electrospun biodegradable polymer networks embedded in polysaccharide-based hydrogels are becoming increasingly popular. This review shows that a major outcome from these works is that nanofiber hydrogels can maintain drug release rates exceeding a few days, even extending into months, which is an extremely difficult task to achieve without the nanofiber texture. This review also demonstrates that some publications still lack careful rheological studies on nanofiber hydrogels; however, rheological properties of hydrogels can influence cell function, mechano-transduction, and cellular interactions such as growth, migration, adhesion, proliferation, differentiation, and morphology. Nanofiber hydrogel rheology becomes even more critical for 3D or 4D printable systems that should maintain sustained drug delivery rates.

Abstract Microneedles (MNs) provide a minimally invasive alternative to intravitreal injections and a promising means to sustainable ocular drug delivery. To optimize the sustained drug release profile and to ease the administration of the MN array to the eye, the number of MNs in an MN array and their layout need to be carefully selected. In this study, the drug release kinetics of MN arrays with varying numbers of MNs (8, 12, and 16) is studied over a four-week period. The MN arrays show a much more uniform drug release profile than the single injections. Only the 16-needle MN array fully released all the amount of loaded drug at the end of the 4-week period. Both 8- and 12-needle arrays showed a steady release rate over the 4-week period, which is the longest sustained release duration that has been reported. Zero-order models are created to predict drug release profiles for the three MN arrays. It is estimated that the MN array with 8 needles can deliver the drug for up to 6 weeks. The models can be used to design MN arrays with a given targeted therapeutic index for sustained drug delivery.

Floating Drug Delivery

Floating drug delivery systems are retained in the stomach and are useful for drugs that are poorly soluble or unstable in intestinal fluid. Floating drug delivery system have a bulk density less than that of gastric fluids and so remain buoyant in the stomach without affecting the gastric emptying rate for a prolong period of time. Research work emphasized on design and evaluates nifedipine floating matrix tablets in which polymers i.e. hydroxyprophyl methyl cellulose (HPMC K100M, K4, and K15) was used. About 15-35 % of HPMC can be used as a polymer in the extended release formulations. So, here the polymer was used in the range of 16-36 %. Sodium bicarbonate (40%) is used as a gas generating agent. It can be used in the range of 25-50 %. The granules are prepared by wet granulation method. The prepared granules were evaluated for the bulk density, tapped density, bulkiness, angle of repose, compressibility index and hausner ratio. The values indicate good flow property. The compressed tablets were evaluated for hardness, uniformity of weight, friability, drug content, buoyancy lag time and duration of buoyancy. All the readings are within the prescribed limits. There was no interaction between the drug, polymer and excipients it was found out by IR studies. The in vitro drug release data indicate that the release of the drug depends upon the proportion of polymer present in the formulation. As the polymer ratio increases the release rate of the drug is prolonged.   Keywords: Floating tablet, HPMC K100M, nifedipine, HPMC K4

Transdermal drug delivery systems (TDDSs) have become innovative, fascinating drug delivery methods intended for skin application to achieve systemic effects. TDDSs overcome the drawbacks associated with oral and parenteral routes of drug administration. The current investigation aimed to design, evaluate and optimize methotrexate (MTX)-loaded transdermal-type patches having ethyl cellulose (EC) and hydroxypropyl methyl cellulose (HPMC) at different concentrations for the local management of psoriasis. In vitro release and ex vivo permeation studies were carried out for the formulated patches. Various formulations (F1–F9) were developed using different concentrations of HPMC and EC. The F1 formulation having a 1:1 polymer concentration ratio served as the control formulation. ATR–FTIR analysis was performed to study drug–polymer interactions, and it was found that the drug and polymers were compatible with each other. The formulated patches were further investigated for their physicochemical parameters, in vitro release and ex vivo diffusion characteristics. Different parameters, such as surface pH, physical appearance, thickness, weight uniformity, percent moisture absorption, percent moisture loss, folding endurance, skin irritation, stability and drug content uniformity, were studied. From the hydrophilic mixture, it was observed that viscosity has a direct influence on drug release. Among all formulated patches, the F5 formulation exhibited 82.71% drug release in a sustained-release fashion and followed an anomalous non-Fickian diffusion. The permeation data of the F5 formulation exhibited about a 36.55% cumulative amount of percent drug permeated. The skin showed high retention for the F5 formulation (15.1%). The stability study indicated that all prepared formulations had very good stability for a period of 180 days. Therefore, it was concluded from the present study that methotrexate-loaded transdermal patches with EC and HPMC as polymers at different concentrations suit TDDSs ideally and improve patient compliance for the local management of psoriasis.
