Currently, on-demand drug release from ultrasound-responsive hydrogels is still difficult to fully control when only using ultrasound. Yeingst et al. suggested that future hydrogel-based delivery platforms will be designed based on the drug payload to optimize the interaction between the ultrasound and stimuli-responsive hydrogel.

Ultrasound has been used to trigger the release of anti-cancer drugs from delivery vectors including liposomes, polymeric microspheres and self-assembled polymeric. [ 15 ] Phonophoresis is a form of soft tissue treatment that involves the use of ultrasound combined with medication gels to enhance drug delivery to the desired area.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
PBMs work with pharmaceutical wholesalers to set up so-called source programs, which control 90% of drug purchasing in the U.S., Oshmyansky explained, noting that Cost Plus Drugs will be as open ...
Ultrasound imaging deposits energy over a large area while therapeutic ultrasound focuses the energy on one target site. Focused ultrasound for intracrainial drug delivery is a non-invasive technique that uses high-frequency sound waves (focused ultrasound, or FUS) to disrupt tight junctions in the blood–brain barrier (BBB), allowing for increased passage of therapeutics into the brain.
Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a small air bubble or a more complex structure.
Patent cliffs be damned, Pfizer (NYS: PFE) is selling rather than buying drugs for its pipeline. Yesterday, AstraZeneca (NYS: AZN) announced that it had licensed an oncology compound, tremelimumab ...
In a 2019 study, they used the drug diclofenac in coordination with thiocolchioside gel to treat patients who suffer from acute lower back pain. [16] An application of a drug serving as a coupling agent is the use of piroxicam gel mixtures and dexamethasone sodium phosphate gel mixtures to treat patients who suffer from carpal tunnel syndrome.
