It is available in the form of an inhaler containing 50 mg total per inhaler and delivering between 0.04 and 0.15 mg of the drug per inhalation. [2] Inhalers with a total of 113 mg levmetamfetamine were previously marketed in the United States, but the total amount was eventually reduced to 50 mg. [ 2 ]
Halothane, sold under the brand name Fluothane among others, is a general anaesthetic. [5] It can be used to induce or maintain anaesthesia. [5] One of its benefits is that it does not increase the production of saliva, which can be particularly useful in those who are difficult to intubate. [5]
Methoxyflurane, sold under the brand name Penthrox among others, is an inhaled medication primarily used to reduce pain following trauma. [5] [6] It may also be used for short episodes of pain as a result of medical procedures. [4]
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.
Sevoflurane is an inhaled anesthetic that is often used to induce and maintain anesthesia in children for surgery. [17] During the process of awakening from the medication, it has been associated with a high incidence (>30%) of agitation and delirium in preschool children undergoing minor noninvasive surgery.

"It looks like inhaled anesthetics act on multiple molecular targets. That makes it a more difficult problem to pick apart." The possibility of anaesthesia by the inert gas argon in particular (even at 10 to 15 bar) suggests that the mechanism of action of volatile anaesthetics is an effect best described by physical chemistry , and not a ...
MDI canister and actuator components from H&T Presspart. A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the ...
Most DPIs rely on the force of patient inhalation to entrain powder from the device and subsequently break-up the powder into particles that are small enough to reach the lungs. [2] For this reason, insufficient patient inhalation flow rates may lead to reduced dose delivery and incomplete deaggregation of the powder, leading to unsatisfactory ...
