Mesoporous silica nanoparticles (MSNs) are introduced as chemically and thermally stable nanomaterials with well-defined and controllable morphology and porosity. It is shown that these particles possess external and internal surfaces that can be selectively functionalized with multiple organic and inorganic groups. Silica nano-particles were synthesized by chemical methods from tetraethylorthosilicate (TEOS), methanol (CH3OH) and deionised water in the presence of sodium hydroxide as catalyst at 80C temperature. The nature and morphology of particles was investigated by scanning electron microscopy (SEM), N2 adsorption/desorption method using BET instrument and X-ray diffraction (XRD). Silica nanoparticles are applicable to a wide range of therapeutic entities from small molecule to peptides and proteins including hydrophobic and hydrophilic entities. Drug loading does not require chemical modification of the molecule; there are no changes in the drug structure or activity after loading and subsequent release of the drug. Thus, well suited to solve formulation problems associated with hydrophobic drugs such as peptide and protein drugs like cyclosporine A. Silica nanoparticles improved the solubility of poorly water soluble drugs and enhanced the absorption and bioavailability of these compounds. Source

Artemether and Lumefantrine capsules are indicated for the treatment of P. falciparum malaria cases resistant to both chloroquine and sulphadoxine, pyrimethamine combination. Both artemether and lumefantrine act as blood schizontocides. Artemether is a sesquiterpene lactone derived from artemisinin. Artemisinin is a compound derived from the sweet wormwood plant and has been used for centuries in traditional Chinese medicine to treat fever. Lumefantrine is a synthetic aryl-amino alcohol antimalarial (quinine, mefloquine and halofantrine are members of the same group). Artemether is absorbed fairly rapidly with peak plasma concentrations reached about 2 hours after dosing. Absorption of lumefantrine, a highly lipophilic compound, starts after a lag period of up to 2 hours, with peak plasma concentration about 6-8 hours after dosing. In order to overcome this problem, we have observed that when the drug is given in the soft gelatin dosage form, the bioavailability of the drug is increased. Thus, increasing the absorption of the drug and peak plasma concentration is reached earlier then the conventional dosage form. Source

The compound ibuprofen, 2-(4-isobutylphenyl) propionic acid, has been known e.g. from Martindale, the Extra Pharmacopoeia, 28 th edition, 1982, p.256, as a drug which had anti-inflammatory and analgesic properties. It is used for the treatment of rheumatoid arthritis or other inflammatory diseases of joints, soft tissue rheumatism and gout. Ibuprofen, because of its analgesic properties, has been widely used as anodyne, e.g. against pain or discomfort associated with headache, toothache or menstruation. A medication suitable to combat acute pain is demanded to display its effects fast which action, in turn, is only achieved by a quick release and good bio-availability of the active-ingredient. It is for the commercial forms in particular that the conditions of preparation must be strictly observed, as minor alterations in production procedures such as mixing, pressure of compression and type of machine will affect the physical properties of the particles of he active ingredient and will deteriorate its bio-availability. It is an object of this presentation to provide a medicament that can be readily taken that contains an active amount of ibuprofen in a carrier, that is simple to prepare and that will quickly display a high activity.
