Vaginal Delivery System Dosage Form

Drug delivery for a long time has been a major problem in the pharmaceutical field. The development of a new Nano-carrier system called nanosponge has shown the potential to solve the problem. Nanosponge has a porous structure and can entrap the drug in it. It can carry both hydrophilic and hydrophobic drugs. They also provide controlled release of the drugs and can also protect various substances from degradation. Nanosponge can increase the solubility of drugs and can also be formulated into an oral, topical and parenteral dosage form. The current review explores different preparation techniques, characterization parameters, as well as various applications of nanosponge. Various patents related to nanosponge drug delivery system have been discussed in this study.

Uterine Relaxation

The PROPESS, a controlled-release dinoprostone vaginal delivery system, is a pharmacological cervical ripening intervention and promotes cervical change causing uterine contraction. During insertion of the PROPESS, uterine hyperstimulation could occur and result in fetal heart rate (FHR) abnormality. We report a case of uterine hyperstimulation accompanied with FHR abnormality caused by the PROPESS in a pregnant woman. Postural change, oxygenation, fluid infusion, and the immediate PROPESS removal were ineffective to address the adverse event, so we administered nitroglycerin for acute uterine relaxation. The nitroglycerin resulted in uterine relaxation, and the FHR abnormality was resolved immediately, thereby preventing an emergency cesarean section. Therefore, nitroglycerin could be considered an effective option for uterine hyperstimulation accompanied with FHR abnormality caused by the PROPESS.

New Drug

A drug delivery system is a system in which a drug is released from a pharmaceutical dosage form to achieve the desired pharmacological effect. The system consists of conventional and new drug delivery systems. In the new drug delivery system, polymers are used as a matrix. The aim of this article is to find out and understand the formulation and evaluation of natural ingredients that have anticancer activity with different dosage forms and the basis for developing these dosages. Journal searches in this review came from primary data sources on the internet. Journal searches were carried out using a search engine such as Google Scholar, PubMed, and ScienceDirect. In recent years, natural products, such as extract, fraction, and isolate, are getting attention to help treat cancer. Because of their low solubility and bioavailability, the effectiveness tends to be lower than synthetic drugs. Therefore, a dosage form with a new drug delivery system was made to overcome the problem. The dosage forms commonly made are patch, suspension, powder, and emulsion with a new drug delivery system. To ensure the product that has been made met the requirements, they need to be evaluated with various methods like In vitro Study, morphology study, particle size study, and others. Cancer treatment using the natural product can be delivered through several dosage forms like patch, suspension, powder, and emulsion, with specific formulation and manufacturing methods based on several considerations such as natural ingredients properties, dosage form selection, excipient properties, and the purpose of the formulation. Dosage forms that has been made are then evaluated using several evaluation methods.

Design Development

The aim of the present study was to develop self-emulsifying drug delivery system (SEDDS) of aceclofenac for potential improvement in the in vitro dissolution. The Food and Drug Control Agency (FDCA) has put more stress on the quality, safety and efficacy of the dosage form. The use of design of experiments and quality by Design (QbD) in the development of self emulsifying drug delivery system (SEDDS) containing aceclofenac is demonstrated. The optimum formulation contained Labrafil M 1944 CS, Tween 80 and Transcutol P. The systematic approach enabled us in identifying the design space. The results revealed that while devising the control strategies during manufacturing, more attention should be focused on the ratios of oil to surfactant and surfactant to co-surfactant. The drug was released at a faster rate due to a large surface area. The current approach enabled us to develop a dosage form which is economic, patient-friendly and does not require assistance of a doctor or nurse, especially at remote places at odd hours.

Aim: Aim of the present work is implementation of Quality by Design principles for the evolution of optimized sustained release drug delivery system Background: Quality by Design (QbD) approach refers to an advance approach to develop a optimized dosage form.QbD has become a vital modern scientific approach to develop a quality dosage form.In modern era of science researcher can develop a optimized dosage form with least effort, money and manpower. Objectives: Objective of research work wasthe successful development of optimized floating bioadhesive tablets of glipizide using floating-bioadhesive potential of cellulosic polymer and carbomersusing quality by design (QbD) approach. Method: Quality Target Product Profile (QTPP) of drug delivery system was defined as well as critical quality attributes (CQAs) were identified. A face centered central composite design (CCD) was utilized in assessing the impact of individual critical material attribute (CMA) like Hydro Propyl Methyl Cellulose K4M(HPMC K4M)and Carbopol 934P (CP 934P) and their interactions, using least experimentation. Formulations were developed and quantitative impact on CQAs was determined using mathematical model. The optimized formulation was obtained and characterized for in-vitro as well as in-vivo parameters. Results: A Fishikawa diagram and Failure Mode and Effect Analysis (FMEA) were performed to identify potential failure modes associated with the dosage form. The optimum formulation was embarked upon using mathematical model developed yielding desired CQAs followed for confirmation of data. Sustained release drug delivery system was successfully developed by using QbD approach. In-vivo X-ray imaging in rabbit and γ-scintigraphic study in manconfirmed the buoyant nature of the mucoadhesive floating tablet for 8 h in the upper gastrointestinal tract. Conclusion: Optimized formulation shows phenomenal floating, bioadhesive properties and drug release retardation characteristics, utilizing a mixture of cost-effective polymers Hence, QbD approach may be regarded as an important tool in development of floating bioadhesive CR dosage forms.
