Aug 23, 2023 · A medication administration route is often classified by the location at which the drug is administered, such as oral or intravenous. The choice of routes in which the medication is given depends not only on convenience and compliance but also on the drug’s pharmacokinetics and pharmacodynamic profile. Therefore it is crucial to understand the characteristics of the various routes and ...

- Oral route. Many drugs can be administered orally as liquids, capsules, tablets, or chewable tablets. Because the oral route is the most convenient and usually the safest and least expensive, it is the one most often used.
- Injection routes. Administration by injection (parenteral administration) includes the following routes: Subcutaneous (under the skin) Intramuscular (in a muscle)
- Sublingual and buccal routes. A few drugs are placed under the tongue (taken sublingually) or between the gums and teeth (buccally) so that they can dissolve and be absorbed directly into the small blood vessels that lie beneath the tongue.
- Rectal route. Many drugs that are administered orally can also be administered rectally as a suppository. In this form, a drug is mixed with a waxy substance that dissolves or liquefies after it is inserted into the rectum.

This is the most frequently used route for drug administration. When possible, it is the first choice for the administration of drugs, since it is both convenient and economical. Drugs administered orally are placed in the mouth and swallowed. Most drugs that are given orally are absorbed into the circulation from the gastrointestinal tract very ef...
In this route of administration, the drug is placed under the tongue (sublingual route) or between gums and inner lining of the cheek (buccal route). In both cases, the drug is allowed to dissolve, avoiding swallowing as far as possible. The drug is rapidly absorbed through the mucosa into circulation, thereby bypassing the portal circulation and, ...
Medications are sometimes ordered to be administered by rectal route. The rectal mucosa is capable of absorbing many soluble drugs into the circulation. Rectal medication may be in suppository form or in liquid form to be administered as a retention enema. Unlike the oral route, drugs with irritant or unpalatable nature can be administered through ...
Drugs are applied topically, that is to the skin or mucous membrane of the eye, ear, nose, mouth, vagina, etc., mainly for local action. This route provides a high local concentration of the drug without affecting the general circulation. However, drugs that are absorbed into the circulation after local administration may then have systemic effects...
The transdermal route is commonly referred to as “the patch” because the medication is contained in a patch that is absorbed through the skin. Drugs administered through this route must be highly lipophilic. Absorption via this route is slow but conducive to producing long-lasting effects. Special slow-release matrices in some transdermal patches c...
Drug delivery by inhalation is a common route, both for local and for systemic actions. This delivery route is particularly useful for the direct treatment of asthmatic problems, using both powder aerosols (e.g. salmeterol xinafoate) and pressurized metered-dose aerosols containing the drug in liquefied inert propellant (e.g. salbutamol sulphate in...
This is the second commonest route of drug administration. They mainly involve introducing the drug in form of solution or suspension into the body at various sites and to varying depths using syringe and needle. Thus administration involves risk of infection, pain, and local irritation. Injection routes of drug administration are usually employed ...
- Oral Route. The drug is administered to or by way of the mouth.1 A drug given via this route is absorbed into the systemic circulation from the gastrointestinal tract.
- Sublingual Route. A dosage form designed for the sublingual (SL) route is administered under the tongue. The drug is absorbed from the blood vessels that lie under the tongue and enters the systemic circulation directly, thus avoiding first-pass metabolism.
- Buccal Route. The buccal route is administered by placing the buccal dosage form between the gum and the inner cheek. The drug is rapidly absorbed from the buccal mucosa and enters the systemic circulation, thus avoiding first-pass metabolism.
- Intravenous Route. A drug administered by the intravenous (IV) route is given directly into a vein as direct injection or infusion. Intravenous Dosage Forms.

Inhalation route. 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 ...
