Design, development, and technical considerations for dry powder inhaler devices.

The dry powder inhaler (DPI) stands out as a highly patient-friendly and effective pulmonary formulation, surpassing traditional and other pulmonary dosage forms in certain disease conditions. The development of DPI products, however, presents more complexities than that of other dosage forms, particularly in device design and the integration of the drug formulation. This review focuses on the capabilities of DPI devices in pulmonary drug delivery, with a special emphasis on device design and formulation development.

Gellan gum-based in situ gelling ophthalmic nanosuspension of Posaconazole.

The formulation and delivery of highly hydrophobic drugs in an optimized dosage form is challenging to formulation scientists. Posaconazole has shown promising action in case studies against fungal keratitis. Biological macromolecules like gellan gum would aid in enhancing the availability of such drugs by increasing the contact time of the formulation.

A triple combination 'nano' dry powder inhaler for tuberculosis: in vitro and in vivo pulmonary characterization.

Inhalation route of drug delivery is the most favorable for pulmonary infections wherein direct drug delivery is desired to the lungs. Tuberculosis is one such infection suffering from poor therapeutic efficacy because of low patient compliance due to high drug dosing and lengthy treatment protocols. The current research work was undertaken to develop a dry powder inhaler (DPI) for administration of three first-line antitubercular antibiotics directly to the lungs to improve the treatment rates.

Comparison of media milling and microfluidization methods for engineering of nanocrystals: a case study.

Objective: The article focuses on exploring and comparing two top-down methods, i.e. media milling and microfluidization for the fabrication of nanocrystals of rifampicin (RIF), a poorly water-soluble drug in terms of their potential for generation of stable and efficacious nanocrystals.

Performance Parameters and Characterizations of Nanocrystals: A Brief Review.

Poor bioavailability of drugs associated with their poor solubility limits the clinical effectiveness of almost 40% of the newly discovered drug moieties. Low solubility, coupled with a high log p value, high melting point and high dose necessitates exploration of alternative formulation strategies for such drugs. One such novel approach is formulation of the drugs as "Nanocrystals".

Multidimensional Ophthalmic Nanosystems for Molecular Detection and Therapy of Eye Disorders.

Symptomatic distresses associated with common ophthalmic infections and their persistence, have remained a tribulation with repeated occurrences. Although being a directly accessible organ, traditional therapeutic strategies exhibiting seemingly fruitful outcome in treatment and prognosis of eye disorders call for improvement in disease intervention. This is due to frequent challenges presented by the ophthalmic environment.

Microbubbles and their applications in pharmaceutical targeting.

Microbubbles are small spherical gas filled bubbles in the size range of 1-10 microns. Their external coat is made of polymers or phospholipids. In combination with ultrasound, they have been explored as contrast agents for ultrasound and also carriers for drug and gene delivery.

Theranostics for cancer therapy.

With over 10 million new cases per year worldwide, Cancer remains one of the most urgent health concerns and a difficult disease to treat. For an effective treatment, improved diagnostic and therapeutic techniques with minimal side-effects are required. Research and development in the areas of nanoscience and nanotechnology promise to provide innovative and more effective approaches for early diagnosis, imaging and therapy.
