A crude way of looking at how we get medicines into the body is this – “if there’s a hole then we’ll put medicines in it and if there is not a hole, then we’ll go and make one”! This article outlines how the intake of medicines is achieved either via absorption or direct injection.

Drugs administered by inhalation through the mouth must be atomized into smaller droplets than those administered by the nasal route, so that the drugs can pass through the windpipe (trachea) and into the lungs. How deeply into the lungs they go depends on the size of the droplets. Smaller droplets go deeper, which increases the amount of drug absorbed. Inside the lungs, they are absorbed into

Parenteral and Inhalation Routes of Administration (3.1) The method used for establishing the PDE for each elemental impurity is discussed in detail in Appendix 1.
These methods are: (1) topical administration, (2) inhalation, (3) oral administration, (4) injection, and (5) rectal administration. Topical administration refers to drug that is applied on a …
Early data on the drug-delivery efficiency of the common aerosol delivery devices (MDI, DPI, and nebulizer) showed lung deposition of approximately 10-15% of the total, nominal dose. Despite problems with low lung deposition with all of the early devices, evidence accumulated that supported the advantages of the inhalation route over other drug-administration routes. Inhaled drugs are

Inhaled administration of drug, directly to the targeted site of action, also has the potential to reduce drug costs, although this must be offset against the costs associated with the equipment required to administer the drug via this route. Additionally, inhaled therapy has the potential to shorten the drug withdrawal time required before competition in performance animals, and in accordance

Prescription opioid analgesics can be abused via intended and non-intended routes of administration, both intact or after manipulation of the original formulation to alter the drug-delivery characteristics. Available data indicate that ingestion (with or without manipulation of the prescribed formulation) is the most prevalent route of abuse, followed by inhalation (snorting, smoking and
inhalation route for therapeutic use is the difﬁculty in regulating the dose given and the cost of the delivery system. Intranasal route is usually used for local application (e.g., oxymetazoline for nasal decongestion) but it may occasionally be used for systemic effects (e.g., desmopressin for diabetes insipidus and calcitonin for osteoporosis). Key Concepts • For a drug to be clinically
to benefit from this route of administration. However, the real impact will be realised when patients are given the opportunity to self-administer therapies in easy-to-use, patient-friendly delivery systems. MannKind’s technology system meets all these requirements and offers the additional advantage of providing unique pharmacokinetics characterised by ultra-rapid drug absorption
Inhalation routes of administration are inhaled through the mouth or the nose and usually act directly on the respiratory system before entering into the bloodstream. They are often used to treat respiratory diseases, but gases are inhaled for general anesthesia as well.
Routes of Administration •Inhalation route –preferred route because • onset is rapid • smaller doses are needed compared to the oral route • side effects e.g. tremor and tachycardia are reduced • drug is delivered directly to the target organ • inhalation is painless and safe –continuous nebulization • continuous administration of inhaled adrenergic agents has been used to
For example, inhalation of asthma drugs is targeted at the airways (topical effect), whereas inhalation of volatile anesthetics is targeted at the brain (systemic effect). On the other hand, identical drugs can produce different results depending on the route of administration. For example, some drugs are not significantly absorbed into the bloodstream from the gastrointestinal tract and their

Often the route of administration of choice is to actuate a pMDI directly into the end of the endotracheal tube (ETT), but this requires breaking into the ventilator circuit and problems can occur due to changes in the design of the pMDI and actuator. 98 A nebulizer can be inserted into the circuit ready to be used if required. 99 Furthermore, drug can bind to the plastic of the ETT, leading
