  • Patent number: 10328027
    Abstract: A new scalable process to control the particle size and the particle size distribution, comprising 5 steps: (i) suspension preparation in a mixture of solvents in which the API and/or excipient is partially soluble in one of the solvents; (ii) particle size reduction of the suspension; (iii) aging; (iv) stopping the aging by solvent removal; and (v) optionally, a step of isolating the processed ingredients in the form of powder.

  • Publication number: 20170056608
    Abstract: A dry powder inhaler (1) for pulmonary or nasal use, employing capsules (6) containing a dose of powder for inhalation, comprising four components: a capsule tray (2), a cover (4) and a mouthpiece (8) and an inhaler body (3). Air is drawn by the patient via the mouthpiece (8) which is in communication with the capsule (6) and travels via air paths through the device (1) and through the capsule (6) thereby dispersing and entraining the dose of powder. The capsule (6) is cut by cutting means (18, 19) located on the body (3). The inhaler body (3), the mouthpiece (8) and the cover (4) are provided with hinge segments (20, 35, 42) which when assembled together and the mouthpiece (8) is locked into the body (3), form a single hinge (5) and which allows the cover (4) to freely pivot around the body (3) and the mouthpiece (8).

  • Patent number: 8677992
    Abstract: A dry powder inhaler for pulmonary or nasal use, employing capsules containing a dose of powder for inhalation, comprising two operating components and an optional cover. Air is drawn by the patient via a mouthpiece or nosepiece which is in communication with the capsule and travels via air paths through the device and through the capsule thereby dispersing and entraining the dose of powder. The capsule is cut by cutting means located on one of the components, in a manner which eliminates or minimizes capsule debris and minimizes powder leakage during use. The inhaler body and capsule cutting blades comprise a single operating component and they may be manufactured in a single unitary step. The invention affords a very economical and simple device for the delivery of pulmonary medicines.

  • Patent number: 8109267
    Abstract: A dry powder inhaler for pulmonary or nasal use, comprising at least an inhaler body and a cartridge with one or more compartments each containing one dose of a drug. The compartment has holes to admit air and holes to deliver powder, which, in use, communicate with an inhalation channel in the inhaler body. To prevent the powder from leaking through the compartment holes before use, the air admission holes are of reduced dimension, thereby blocking or hindering powder exit under the force of gravity. When the cartridge is inserted inside the inhaler body, all its holes can be blocked. By sliding the cartridge in relation to the body until the inhalation position is reached, the holes come into in fluid communication with one another and with the inhalation channel, thereby allowing a flow of air to disperse and entrain the dose through the mouthpiece. Five embodiments are disclosed.

  • Patent number: 5881721
    Abstract: Apparatus for orienting elongate objects, for example capsules of medicament, comprises a passage for receiving an individual capsule in a preferred orientation, a container for holding a bulk supply of capsules, and a ramp surface which directs a capsule towards the passage when the device is positioned such that the passage extends vertically downwardly from the container. It has been found that by appropriate choice of ramp angle, passage diameter and container diameter there is a high probability that a single capsule will be loaded into the dispensing passage when the apparatus is inverted to place the dispensing passage below the bulk supply. The apparatus is particularly useful in a dry medicament dispensing apparatus comprising, in addition to the orienting apparatus, a chamber for receiving capsules from the dispensing passage, means for piercing the ends of the capsule, and a mouthpiece for drawing air through the capsule and to entrain the medicament.

  • Patent number: 5673686
    Abstract: A new inhalation device, which during operation causes an aerosol to be formed inside a chamber such as a capsule (4) which occludes one end (3) of the inhalation tube (1), the capsule having holes at its extremities (7,8) which admit airflow. The airflow causes the powder contained inside the capsule to be surprisingly transported to the capsule extremity contrary to the direction of inhalation, that is towards the air entry holes in the capsule, and then to form an aerosol until all powder has been removed from the capsule or chamber through the tube (1), the during of inhalation being chiefly regulated by the size and proportion of the capsule holes. The tube (1) has air inlets downstream of the capsule to permit a balanced airflow that will transport the finely suspended powder into the lungs, maximizing the fraction of medicament deposited therein.
