Abstract: An amorphous solid dispersion of efonidipine hydrochloride having a high intestinal absorbability can be formed by subjecting a mixture containing efonidipine hydrochloride of the formula (I), hydroxypropylmethylcellulose acetate succinate and optionally a thermostabilizer to a step A of heat treatment at from 85 to 140° C. or mechanochemical treatment at from 0 to 140° C., and then to a step B of dipping treatment into a water-containing solution, impregnation treatment with a water-containing solution or contacting treatment with a water vapor-containing gas; or treating the above-mentioned mixture with a hot steam at from 100 to 140° C. and a high pressure. Further, in the above-mentioned step A, the mixture is subjected to high frequency heating, making it possible to give a solid dispersion of efonidipine hydrochloride having a high intestinal absorbability without using the step B. This process is quite advantageous in the production in that the use of an organic solvent is not required.

Abstract: The invention is directed to a device for delivering an active agent formulation for a predetermined administration period. An impermeable reservoir is divided into a water-swellable agent chamber and an active agent formulation chamber. Fluid from the environment is imbibed through a semipermeable plug into the water-swellable agent chamber and the active agent formulation is released through a back-diffusion regulating outlet. Delivery periods of up to 2 years are achieved.

Abstract: An antirheumatic agent comprising diethyl L-lysylcromoglycate of the following formula ##STR1## or a nontoxic salt thereof as an active ingredient. This compound has an anti-inflammatory action and immunomodulating action, is absorbed by oral administration to be delivered efficiently to local sites, and is associated with fewer side effects, so that it serves well as an antirheumatic agent that can be administered orally.
Abstract: The invention features an implantable device for the automatic delivery of an active ingredient according to an adjustable delivery profile. The device includes a housing; a reservoir operatively connected to the housing and arranged to store a solid composition including the active ingredient; an actuator arranged within the housing to move the solid composition from the reservoir to a transit area, wherein the solid composition exits the housing at the transit area; a controller that acts on the actuator to adjust movement of the solid composition out of the housing according to the adjustable delivery profile; and a power source arranged to provide energy to the actuator and the controller. The solid composition can be an elongate, solid composition comprising a drug, and up to 90% of a carrier, wherein the composition has a cross-section of less than 0.
Abstract: Novel phenethyl-5-bromopyridylthiourea (PBT) and dihydroalkoxybenzyloxopyrimidine (DABO) derivatives exhibiting spermicidal activity as well as anti-viral activity. These novel compounds can be incorporated within contraceptive compositions to provide for spermicidal or sperm-immobilizing activity.
