Formulation and evaluation of transparent ibuprofen soft gelatin capsule

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.
