The aim of the present investigation was to prepare a colloidal ophthalmic formulation to improve the residence time of moxifloxacin. Moxifloxacin-loaded poly(dl-lactide-co-glycolide) (PLGA) nanosuspensions were prepared by using the solvent evaporation technique. The nanosuspensions were characterised physically by using different techniques like particle size, zeta potential, FTIR, DSC, and X...
Purpose: To prepare and optimize esomeprazole nanosuspension to enhance drug dissolution rate. Methods: Esomeprazole nanosuspensions were prepared by evaporative precipitation-ultrasonication method using F68 (Poloxamer 188) and F127 (Poloxamer 407) as stabilizers. Formulation and process variables (concentration of stabilizers and drug, power input and duration of ultrasonication) affecting th...
The rate of dissolution of drugs remains one of the most challenging aspects in formulation development of poorly water-soluble drugs. The meloxicam, a low molecular analgetic for oral administration, exhibits a slow dissolution. To improve the dissolution rate, the drug was formulated in a nanosuspension by using an emulsion-diffusion method, high-pressure homogenization or sonication. Optimiz...
This study aimed to comprehensively assess the transcorneal permeation, antimicrobial, and antifungal activities of a nanosuspension loaded with Andrographolide, promising herbal compound. Through combination in vitro vivo studies, efficacy, potential applications ocular drug delivery were investigated. In phase, permeation studies conducted using Franz diffusion cells excised rabbit corneas. T...
Poor ocular bioavailability of drugs (<1%) from conventional eye drops (i.e., solution, suspension, and ointments) is mainly due to the physiologic barriers of the eye. In general, ocular efficacy is closely related to ocular drug bioavailability, which may be enhanced by increasing corneal drug penetration and prolonging precorneal drug residence time. In our current work, we developed a collo...
The present study was performed to design and evaluate the famotidine loaded mucoadhesive nanosuspension for aspirin induced ulcer. A 3-factor, 3-level Box-Behnken design was applied to study the effects of amount of the beads (X1), PVPK-30(X2) and Tween-80 (X3) on the particle size (Y1), and cumulative percentage drug released after 1h (Y2). The optimization was performed using the desirabilit...
BACKGROUND Nanosuspensions are an important class of delivery system for vaccine adjuvants and drugs. Previously, we developed a nanosuspension consisting of the synthetic TLR4 ligand glucopyranosyl lipid adjuvant (GLA) and dipalmitoyl phosphatidylcholine (DPPC). This nanosuspension is a clinical vaccine adjuvant known as GLA-AF. We examined the effects of DPPC supplier, buffer composition, and...
PURPOSE OF REVIEW Long-acting cabotegravir may provide a novel therapeutic option for both the treatment and prevention of HIV-1 infection that does not necessitate adherence to a daily regimen. The present review will highlight the unique formulation properties and pharmacologic attributes of long-acting cabotegravir nanosuspension. RECENT FINDINGS Cabotegravir is a potent integrase strand t...
