Enhanced alveo pulmonary deposition of nebulized ciclesonide for attenuating airways inflammations: a strategy to overcome metered dose inhaler drawbacks.

Ciclesonide (CIC), an inhaled corticosteroid for bronchial asthma is currently available as metered dose inhaler (CIC-MDI) which possesses a major challenge in the management of the elderly, critically ill patients and children. In this work, nebulized CIC nano-structure lipid particles (CIC-NLPs) were prepared and evaluated for their deep pulmonary delivery and cytotoxicity to provide additional clinical benefits to patients in controlled manner and lower dose. The bio-efficacy following nebulization in ovalbumin (OVA) induced asthma Balb/c mice compared to commercial (CIC-MDI) was also assessed.

Pharmaceutical and medical aspects of hyaluronic acid-ketorolac combination therapy in osteoarthritis treatment: radiographic imaging and bone mineral density.

The objective of this study was to formulate novel painless combined hyaluronic acid (HA)-ketorolac (KT) membrane for the management of osteoarthritis with rapid analgesic onset, thus avoiding HA frequent invasive intra-articular injections and KT gastrointestinal complaints associated with all non-steroidal anti-inflammatory drugs. HA was chemically crosslinked with carbodiimide/glutaraldehyde to yield membrane of low water content. Different in vitro aspects (mechanical properties, water content and in vitro release) were studied leading to an optimized soft, flexible K8 HA membrane containing 30 mg KT that achieved the desired balance of excellent elasticity and low water content.
