摘要:
The invention provides a process for the preparation of granules comprising a pharmaceutical which comprises contacting a particulate, spray-dried substrate and a particulate pharmaceutical to obtain particles comprising a substrate core carrying an adsorbed pharmaceutical and contacting those particles with a particulate pharmaceutical and a melted or thermally softened pharmaceutically acceptable excipient which is solid at room temperature to obtain, after cooling to solidify or harden the excipient, granules comprising a spray-dried substrate core carrying pharmaceutically acceptable excipient and pharmaceutical.
摘要:
This invention relates to an abuse resistant tablet containing two or more layers comprising one or more drugs and one or more gelling agents wherein the drug(s) and gelling agent(s) are contained in separate layers of the tablet. The multilayer tablet is particularly suitable for the administration of drugs prone to abuse by unauthorised parenteral administration such as analgesics, hypnotics and anxiolytics.
摘要:
An inhaler for powdered medicament in capsules has a swirling chamber which can be opened to allow access of a closed capsule into the swirling chamber for operation of capsule-opening means in the swirling chamber. Access to the swirling chamber is gained by a pivoting cover member (22) which is provided with interlock means associated with the capsule-opening means to ensure that the capsule opening means cannot be operated while the cover member is in its open position to allow access of the user's fingers to the region (28) of the swirling chamber (26, 28) where the capsule-opening pins (30) could damage the user's finger.
摘要:
This invention is directed to 1-alkoxy-2-(alkoxy- or cycloalkyloxy-)-4-(cyclothioalkyl- or cyclothioalkenyl-)benzene compounds that inhibit cyclic AMP phosphodiesterase or tumor necrosis factor (TNF) and are useful in treating patients suffering from disease state capable of being modulated by inhibiting production of cyclic AMP phosphodiesterase or TNF by administering the compound to the patient. The invention is also directed to the preparation of these compounds, pharmaceutical compositions containing these compounds and methods for their pharmaceutical use.
