Jet injector - Wikipedia

    https://en.wikipedia.org/wiki/Jet_injector
    A jet injector is a type of medical injecting syringe device used for a method of drug delivery known as jet injection, in which a narrow, high-pressure stream of liquid penetrates without needle the outermost layer of the skin (stratum corneum) to deliver medication to targeted underlying tissues of the epidermis or dermis ("cutaneous" injection, also known as classical "intradermal ...

Pulmonary drug delivery Clinical Gate

    https://clinicalgate.com/pulmonary-drug-delivery/
    Pressurized metered-dose inhalers (pMDIs), also referred to as metered-dose inhalers (MDIs), were introduced in the mid-1950s and are the most commonly used inhalation drug delivery devices. In pMDIs, drug is either dissolved or suspended in liquid propellant(s) together with other excipients, including surfactants, and presented in a ...

    Pressurized metered-dose inhalers (pMDIs) are sometimes viewed as old-fashioned and as having been superseded by dry powder inhalers (DPIs). Here, we review the technological advances that characterize modern pMDIs, and consider how they can influence the effectiveness of drug delivery for patients with asthma and chronic obstructive pulmonary disease.Author: N.

    Yousef Javadzadeh, Shadi Yaqoubi, in Nanostructures for Drug Delivery, 2017. 6.2 Metered Dose Inhaler (MDI) Metered-dose inhaler is an inhaler device with specified doses that provides a certain dose of the active agent in each puff. MDIs consist of a suspension or dispersion of one or more active ingredient in propellant or a mixture of propellants or a mixture of solvent and propellants, are ...

    Drug-Delivery Technique While spacers and VHCs provide many benefits for opti-mal drug delivery with pMDIs, there are also potential prob-lems with their use (see Table 9). Improper technique may decrease drug delivery or, in some cases, cause the dose to be lost. Possible causes of decreased drug delivery include multiple actuations into Table 9.

    Drug Delivery From Spacer Devices Summary The pressurized metered-dose inhaler (pMDI) was introduced to deliver asthma medications in a convenient and reliable multi-dose presentation. The key components of the pMDI device (propel-lants, formulation, metering valve, and actuator) all play roles in the formation of the spray, and
