The objective was to develop optimized gastric floating drug delivery system (GFDDS) of candesartan celexetil floating tablets by using various polymers like Eudragit and MCC. In the present work, attempts have been made to prepare candesartan celexetil by direct compression method by using Citric acid, NaHCO3, Magnesium stearate, Eudragit and MCC. Formulations (F1 to F4) of floating tablets of candesartan celexetil were prepared using variable concentrations of Eudragit and MCC. The prepared formulations were evaluated for thickness, hardness, weight variation, friability, drug content and uniformity. The buoyancy lag time and the total floating time was studied for all the formulations. Formulation F4 of sustained release tablet of Candesartan celexetil containing a combination of both polymers was found to be the optimized formulation for 13 hours release as it fulfilled all the requirement of floating drug delivery system of sustained release dosage form.

Floating Drug Delivery System

The oral route is increasingly being used for the delivery of therapeutic agents because the low cost of the therapy and ease of administration lead to high level of patient compliances.  Floating drug delivery system (FDDS) float in the gastric fluid and prolong GRT to obtain sufficient drug bioavailability, because of their lower bulk density compared to that of the aqueous medium. The aim of the present study is to prepare floating tablets as a delivery system for controlled release of Ketoconazole. Ketoconazole is a drug of choice in antifungal category and gives significant result. Floating tablets containing Ketoconazole were prepared by direct compression technique using varying concentrations of different grades of polymers of Hydrxy Propyl Cellulose & Xanthan gum. To evaluate the prepared floating tablets for various parameters like hardness, friability, uniformity of drug content, in-vitro floating studies, in-vitro dissolution studies.

Abstract Purpose The aim of this study was to formulate methscopolamine floating drug delivery system to increase its gastro retention for further enhancement of absorption and overall bioavailability. Method Direct compression method was used to formulate floating drug delivery system of methscopolamine bromide. Different amount of HPMC, PVP K25, and MCC were used for preparation of tablets. Result The prepared tablets were evaluated for thickness, hardness, weight variation, floating lag time, swelling index and in-vitro drug release. All the formulations showed less than 10% of weight variation. The hardness and thickness of all the formulations were within the range of 3.7−4.2 kg/cm2 and 3.63−3.83 mm respectively. Floating lag time for all the formulations was reported in seconds. The degree of swelling was reported in range of 82.10−85.83%. In vitro release was carried out for 24 h. The maximum release was shown by F1 (93.947%) while the minimum release was observed for F4 (90.420%). The best formulation was optimized on the basis of percentage cumulative drug release, floating lag time and swelling index. F1 found to be the best formulation. Further on analyzing the drug release mechanism, F1 found to exhibit korsmeyer peppas model of drug release. Conclusion Floating gastroretentive tablet of methscopolamine bromide was successfully developed using direct compression method with potential to enhance the drug absorption and effective treatment of peptic ulcer.

Floating Drug Delivery System

Presently, various approaches have been exploited in the prolongation of gastric residence time which includes floating drug delivery system (FDDS), swelling and expanding systems, bio-adhesive systems, modified shape systems and high density systems. Among various methods, floating drug delivery system is considered to be a predominant method. Gastric emptying of dosage forms is an extremely varying process and ability to extend and control the emptying time is a valuable resource for the dosage forms. This FDDS is having the ability to provides a solution for this purpose. The FDDS is a bulk density system lower than the gastric fluid, so that the rest will float on the stomach contents for a prolonged period of time and allowing the drug to release slowly at a desired rate from the system and intensifies the bio-availability of the drug having narrow absorption window. The main intension of writing this review on floating drug delivery system is to study the mechanism of flotation to acheive the gastric retention and to discuss briefly about the background of FDDS, advantages and disadvantages, application of FDDS and factors affecting the gastric retension time.

Floating Drug Delivery System

The main goal of any drug delivery system is to achieve desired concentration of the drug in blood or tissue, which is therapeutically effective and non-toxic for a prolonged period. Current pharmaceutical scenario focuses on the formulation of floating drug delivery system (FDDS). FDDS are low density systems that float over the gastric contents and remain buoyant in the stomach for a prolonged period of time without affecting the gastric emptying rate. The aim of writing this review is to compile the current literature with special focus on the principal mechanism of floatation to attain gastric retention. Effervescent FDDS release CO2 gas, thus reduce the density of the system and remain buoyant in the stomach for a prolonged period of time and released the drug slowly at a desired rate so it can be used to prolong the gastric residence time in order to improve the bioavailability of drug. The review briefly describes the mechanism, types of floating system, advantages, limitation, factors affecting floating system, drug candidates suitable for floating, evaluation parameters and application of the system. These systems are useful to several problems encountered during the development of a pharmaceutical dosage form and the future potential of FDDS. Keywords: Floating drug delivery system, Absorption Window, Effervescent system, floating lag time.
