What does s for orally administered medications compare with those administered by parenteral routes?
The bioavailability of orally administered medications is generally lower than that of parenteral routes, primarily due to factors like first-pass metabolism in the liver and variability in absorption from the gastrointestinal tract. Oral medications can have delayed onset of action due to the time required for digestion and absorption. In contrast, parenteral routes, such as intravenous or intramuscular administration, provide more immediate and predictable drug effects, as they bypass the digestive system entirely. However, oral medications are often more convenient and less invasive for patients.

What is a non parenteral drug?
A non-parenteral drug is one that is administered orally or by inhalation. Examples would be swallowing a pill or using an inhaler. Parenteral drugs are administered by injection or via transdermal patch (applied directly to the skin).
What is a non-parenteral drug?
Parenteral administration is any administration that is not via the GI system, meaning oral or rectal. Parenteral means "around the enteral system." Intravenous, subcutaneous, and intramuscular injections are all parenteral routes of administration. While inhalation would be considered parenteral in the strictest sense of the word, inhalation or aerosolization of medications are not usually considered parenteral, nor is topical administration.
Why all drugs are not given through parenteral route?
Most take medications at home and do not have the training nor the equipment to do so. Only drugs designed and intended for administration via a parenteral route should be taken that way. If drugs designed to be taken orally are administered parenterally the "user" could be harmed, and the medication may work very differently than intended. In addition, most drugs are tested as orally administered medications. The way they are absorbed, how they are metabolized, and the dose and time to effect are all designed for oral administration.
What is parenteral products?
Parenteral products are pharmaceutical formulations that are administered via injections, bypassing the gastrointestinal tract. They include solutions, suspensions, or emulsions intended for intramuscular, intravenous, or subcutaneous delivery. These products are often used for medications that require rapid onset of action or cannot be taken orally due to instability or poor absorption. Parenteral formulations must meet strict sterility and stability standards to ensure patient safety and efficacy.
What does PR in mean in a prescription?
In a prescription, "PR" stands for "per rectum." It indicates that the medication should be administered rectally. This route is often used for medications that need to be absorbed quickly or for patients who are unable to take medications orally.
What are the most effective antifungal medications for dogs and how should they be administered?
The most effective antifungal medications for dogs are usually prescribed by a veterinarian and may include medications like ketoconazole, itraconazole, or fluconazole. These medications are typically administered orally in the form of tablets or liquid, following the dosage instructions provided by the veterinarian. It is important to follow the veterinarian's guidance and complete the full course of treatment to effectively combat the fungal infection in dogs.
Is sodium bicarbonate can give intramuscular injection?
No, sodium bicarbonate is typically given orally or intravenously, but not intramuscularly. Intramuscular injections are usually administered with medications that are specifically formulated for that route of administration.
How does the hepatic portal circuit affect the efficacy of oral medications?
The hepatic portal circuit is responsible for transporting blood from gastrointestinal tract to the liver. Certain medication which are administered orally cannot be passed via this system and therefore should be administered via alternative methods such as injections.
Can iv haldol solution be given orally?
Yes, you could give the haloperidol solution orally, but the onset of action will not be as rapid as if you give it parenterally (intravenously or intramuscularly) and at typical parenteral doses, the efficacy may not be as complete.
In what situations is parenteral administration used?
Parenteral administration is used when the patient is unable to take the drug orally, rapid action of medication is needed, and medication is ineffective in the gastrointestinal tract. Parenteral administration is also used to avoid the gastrointestinal tract and its first pass effect and to delivery medication to specific organs or tissues.
How is Oxycodone administered?

How does an orally administered drug get from the GI tract to the brain?
