Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
In other words, it is the ratio of amount of drug in a body (dose) to concentration of the drug that is measured in blood, plasma, and un-bound in interstitial fluid. [3] [4] The V D of a drug represents the degree to which a drug is distributed in body tissue rather than the plasma.
A drug of last resort (DoLR), also known as a heroic dose, [1] is a pharmaceutical drug which is tried after all other drug options have failed to produce an adequate response in the patient. Drug resistance , such as antimicrobial resistance or antineoplastic resistance , may make the first-line drug ineffective, especially in case of ...
Vancomycin is a glycopeptide antibiotic medication used to treat certain bacterial infections. [7] It is administered intravenously (injection into a vein) to treat complicated skin infections, bloodstream infections, endocarditis, bone and joint infections, and meningitis caused by methicillin-resistant Staphylococcus aureus.

A double-handled glass vial from Syria, c. 4th century AD [1] A vial can be tubular, or have a bottle-like shape with a neck. The volume defined by the neck is known as the headspace. The English word "vial" is derived from the Greek phiale, [2] meaning "a broad flat container". [3]
It is commonly used with a syringe, a hand-operated device with a plunger, to inject substances into the body (e.g., saline solution, solutions containing various drugs or liquid medicines) or extract fluids from the body (e.g., blood). Large-bore hypodermic intervention is especially useful in catastrophic blood loss or treating shock.
The V/Q ratio can therefore be defined as the ratio of the amount of air reaching the alveoli per minute to the amount of blood reaching the alveoli per minute—a ratio of volumetric flow rates. These two variables, V and Q, constitute the main determinants of the blood oxygen (O 2 ) and carbon dioxide (CO 2 ) concentration.
A tiger top tube after centrifugation to separate blood cells from serum. Vacutainer tubes may contain additional substances that preserve blood for processing in a medical laboratory. Using the wrong tube may make the blood sample unusable for the intended purpose. These additives are typically thin film coatings applied using an ultrasonic ...
