Injection, drug administration rout

Drug administration route Extended-release injectable naltrexone 380 mg for alcohol dependence in primary care settings in 72 patients seeking treatment produced good patient satisfaction, and adverse reactions were as expected [216 "]. 

Drug administration route Accidental injection of adrenaline into fingers seems not to be associated with adverse reactions in most cases, although occasional reports appear [12" ]. 

Drug administration route The authors compared a new and old adrenaline autoinjector with respect to correct autoinjector use. The new adrenaline autoinjector is more effective in unintentional injection injuries than the old one however, it still does not fulfil the criteria of an ideal adrenaline autoinjector [24 ]. 

Drug administration route There is a greater risk of developing ketoacidosis with insulin-pump therapy than with multiple daily insulin injections, because there is always a smaller subcutaneous depot of insulin at any time with the insulin pump. However, in practice, the frequency of ketoacidosis is similar with insulin pump and insulin injections. Insulin-pump therapy can lead to some localised non-serious skin infections at the infusion site. In general, current pumps are robust and reliable, but malfunctions can still occur. [15 ]... 

Parenteral drug administration means the giving of a drug by the subcutaneous (SC), intramuscular (IM), intravenous (IV), or intradermal route (Fig. 2-5). Other routes of parenteral administration that may be used by the primary care provider are intralesional (into a lesion), intra-arterial (into an artery), intracardiac (into the heart), and intra-articular (into a joint), hi some instances, intra-arterial dragp are administered by a nurse. However, administration is not by direct arterial injection but by means of a catheter that has been placed in an artery. 

The fate of injected liposomes is drastically altered by administration route, dose and size, lipid composition, surface modification, and encapsulated drugs. Liposomes encapsulating drugs are often administered iv, therefore, the stability of liposomes in plasma is important. When liposomes composed of PC with unsaturated fatty acyl chains are incubated in the presence of serum, an efflux of internal solute from the liposomes is observed. This increase in permeability is caused by the transfer of phospholipids to high density lipoprotein (HDL) in serum (55). To reduce the efflux of liposomal contents, cholesterol is added as a liposomal component... 

Liposomes tend to remain at the injection site when they are administered intramuscularly or subcutaneously. Therefore, these administration routes are useful for slow and sustained release of drugs at the injection site. 

The IM and SC routes are by far the most frequently used extravascular parenteral routes of drug administration in farm animals. The less frequently used parenteral routes have limited application, in that they aim at directly placing high concentrations of antimicrobial agent close to the site of infection. These routes of administration include intra-articular or subconjuctival injection and intra-mammary or intra-uterine infusion. These local routes differ from the major parenteral routes in that absorption into the systemic circulation is not a prerequisite for delivery of drug to the site of action. The combined use of systemic and local delivery of drug to the site of infection represents the optimum approach to... 

IV route of ac/m/n/sfraf/on- Warfarin injection provides an alternative administration route for patients who cannot receive oral drugs. The IV dosages would be the same as those that would be used orally if the patient could take the drug by the oral route. Administer as a slow bolus injection over 1 to 2 minutes into a peripheral vein. It is not recommended for IM administration. 

Some of the dosage formulations available for protein pharmaceuticals are listed in Table 5.7. An examination of Table 5.7 reveals that no protein drug up until this time has been formulated for oral administration. Most protein drugs are administered by means of injection (parenteral administration). Parenteral administration includes intravenous, intra-arterial, intracardiac, intraspinal or intrathecal, intramuscular, intrasynovial, intracuta-neous or intradermal, subcutaneous injections, and injection directly into a dermal lesion (e.g., a wart). The parenteral route of administration requires a much higher standard of purity and sterility than oral administration. It also may require trained... 

Some limitations are that the amount of drug that can be injected in this fashion is fairly small and that the injected drug must not irritate or inflame the subcutaneous tissues. The subcutaneous route can also be used when certain types of drug preparations are implanted surgically beneath the skin, so that the drug is slowly dispersed from the implanted preparation and then absorbed into the bloodstream for prolonged periods of time.62,86 A common example of this form of subcutaneous administration is the use of implanted hormonal contraceptive products (e.g., Norplant).9,53 The use of these implantable contraceptives is discussed in more detail in Chapter 30. 

Most muscle relaxants are absorbed fairly easily from the gastrointestinal tract, and the oral route is the most frequent method of drug administration. In cases of severe spasms, certain drugs such as methocarbamol and orphenadrine can be injected intramuscularly or intravenously to permit a more rapid effect. Likewise, diazepam and dantrolene can be injected to treat spasticity if the situation warrants a faster onset. As discussed earlier, continuous intrathecal baclofen administration may be used in certain patients with severe spasticity, and local injection of botulinum toxin is a possible strategy for treating focal dystonias and spasticity. Metabolism of muscle relaxants is usually accomplished by hepatic microsomal enzymes and the metabolite or intact drug is excreted through the kidneys. 

Many drugs listed in the Brand and Generic Name Index have several variations on the trade name, depending on different forms of the drug and routes of administration. For example, a drug that is available in tablets, capsules, and injectable forms may have slight variations on the trade name that reflect these different preparations. 

Parenteral administration Administration of drugs by routes other than via the alimentary canal by injection, transdermally, topically, and so on.
