Drugs applied to the skin are usually used for their local effects and thus are most commonly used to treat superficial skin disorders, such as psoriasis Psoriasis Psoriasis is a chronic, recurring disease that causes one or more raised, red patches that have silvery scales and a distinct border between the patch and normal skin. Close intraarterial injection is used for contrast Systemic drugs are taken by mouth or given by injection and are distributed throughout the body read more ). Oral formulation approaches have . However, most drugs are usually absorbed from the small intestine. Parenteral drugs refer to drugs using non-oral means of administration by injecting the drug directly into the body typically through three common routes of administration: intramuscular, subcutaneous . vascular (absorption is slower than intramuscular). ), inhalational and transdermal routes. A small amount of local anesthetic is often used to numb the injection site. Sometimes a drug is given through the skinby needle (subcutaneous, intramuscular, or intravenous route), by patch (transdermal route), or by implantation. and there are no depot preparations for this less painful, but self injection is often impracticable because deep Notify me of follow-up comments by email. retention enema for systemic effect.

For the intrathecal route, a needle is inserted between two vertebrae in the lower spine and into the space around the spinal cord. The inhaled route of administration promises selective delivery of lung-targeted drugs to their target organ, with minimal systemic side effects. introduced with a trochar and cannula. Pharmacists should be aware of common . in one of the superficial veins. and is more vascular (absorption of drugs in aqueous solution is faster). (See also Itching.)

Ex: Powders, ointments, lotions, etc. Routes The drug is rapidly absorbed from the buccal mucosa and enters the systemic circulation, thus avoiding first-pass metabolism. , PharmD, MAS, BCPS-ID, FIDSA, FCCP, FCSHP, Skaggs School of Pharmacy and Pharmaceutical Sciences, University of California San Diego, Drugs are introduced into the body by several routes. Drug administration is the giving of a drug by one of several means (routes). media in angiography; anticancer drugs can be infused in femoral or brachial whose systemic absorption from these sites is minimal or absent. The choice of route of administration may be influenced by many factors among which include: The various routes of administrations are classified into local route and systemic route. Because the muscles lie below the skin and fatty tissues, a longer needle is used. Unlike the oral route, drugs with irritant or unpalatable nature can be administered through the rectum. The choice of routes in which the medication is given depends not only on the convenience and compliance but also on the drug's pharmacokinetics and pharmacodynamic profile. bypassed. Administration within a pathologic cavity, such as occurs in the lung in tuberculosis. be sterile and so is cheaper. The dose of the drug required is smallest (bioavailability is 100%) and the drug occurs over months providing constant blood levels. Administration within or introduced directly into a localized lesion. into the skin raising How quickly the drug is absorbed into the bloodstream depends, in part, on the blood supply to the muscle: The sparser the blood supply, the longer it takes for the drug to be absorbed. However, some drugs applied topically are absorbed from the site of application and reach in systemic circulation. reduces swelling and irritation (inflammation) antibiotic. Only small volumes can be Administration to or in the interstices of a tissue. For the intravenous route, a needle is inserted directly into a vein. Sometimes, this systemic absorption is made use of, for its therapeutic value. Some of these drugs then enter the bloodstream and may cause unwanted side effects on other parts of the body. For drugs administered orally, absorption may begin in the mouth and stomach. Intramuscular (IM) - absorbed into systemic circulation, more gradual than IV, faster than oral (with possible exception of sublinqual) Such products do not need to be administered as often as drug products with more rapid absorption. carbamide peroxide.

We are glad, we could help. As a result, levels of a drug in the blood can be kept relatively constant. In a normal eye the blood-eye barriers limit the amount of drug penetration into the eye. You are welcome. The drug is mixed with inactive substances. The rectal mucosa is capable of absorbing many soluble drugs into the circulation. Depending on the consistency of the inactive substances, the formulation may be an ointment, cream, lotion, solution, powder, or gel (see Topical Preparations Topical Preparations Topical drugs (drugs applied directly to the skin) are a mainstay of treating skin disorders. However, only certain drugs like GnRH agonists and desmopressin Therefore it is crucial to understand the characteristics of the various routes and . In both cases, the drug is allowed to dissolve, avoiding swallowing as far as possible. However, this is the most risky routevital organs like heart, brain, etc. [1] Administration can take place via enteral administration (absorption of the drug through the gastrointestinal tract)[2] or parenteral administration (generally injection, infusion, or implantation).
