The process of mucoadhesion has been widely studied using a wide variety of methods, which are influenced by instrumental variables and experiment design, making the comparison between the results of different studies difficult. The aim of this work was to standardize the conditions of the detachment test and the rheological methods of mucoadhesion assessment for semisolids, and introduce a texture profile analysis (TPA) method.

The aim of the current investigation was to develop solid lipid nanoparticles of olmesartan medoxomil using hot homogenization method to improve its oral bioavailability. Central composite design was applied to optimize the formulation variables; lipid X1 (Glyceryl monostearate) and surfactant X2 (Poloxamer: Tween 80).

Candesartan cilexetil is an ester prodrug antagonist to angiotensin II receptor type 1 (AT1) used in management of many cardiovascular diseases. The absolute bioavailability of candesartan cilexetil is about (14–40%). Therefore, the paper aim was to prepare and evaluate solid self-nanoemulsifying drug delivery systems for candesartan cilexetil in order to improve its solubility, dissolution and stability. Solubility study was run in different vehicles to select the best excipients for dissolving

Use of a self-microemulsifying drug delivery system (SMEDDS) is widely known as one of the most effective approaches to overcome problems associated with low solubility and poor oral absorption of water-insoluble drugs. Previously, we have demonstrated that a super saturable SMEDDS (SuSMEDDS) greatly contributed to enhanced dissolution and oral absorption of valsartan (VST), a drug with poor solubility in water ...

The aim of this new work was to improve the dissolution rate of poorly water-soluble cilostazol (CLT) by adsorbing dissolved drug molecules onto the surface of undissolved carriers via reprecipitation and deposition process as the solvent (methylene chloride) was evaporated. The adsorption mixtures of CLT with Aerosil 300 and lactose monohydrate provided better drug dissolution rate as compared to mannitol.
