Polymers of hyaluronic acid can range in size from 5,000 to 20,000,000 Da in vivo. The average molecular weight in human synovial fluid is 3–4 million Da, and hyaluronic acid purified from human umbilical cord is 3,140,000 Da; [ 4 ] other sources mention average molecular weight of 7 million Da for synovial fluid.

This is generally defined by the range between the minimum effective dose (MED) and the maximum tolerated dose (MTD). The MED is defined as the lowest dose level of a pharmaceutical product that provides a clinically significant response in average efficacy, which is also statistically significantly superior to the response provided by the ...
Ripasudil has been proven to have additional medical uses aside from reducing IOP and alleviating symptoms of glaucoma and ocular hypertension. For example, in March 2016 the drug was shown to promote corneal endothelial cell (CEC) proliferation in cultured human cells as well as wound healing and endothelium regeneration in a rabbit wound ...
In single-dose scenarios, the patient's body weight and the drug's recommended dose per kilogram are used to determine a safe one-time dose. If multiple doses of treatment are needed in a day, the physician must take into account information regarding the total amount of the drug which is safe to use in one day, and how that should be broken up ...
A dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis. In some cases, it is the logarithm of the dose that is plotted on the ...
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
The term dosage form may also sometimes refer only to the pharmaceutical formulation of a drug product's constituent substances, without considering its final configuration as a consumable product (e.g., capsule, patch, etc.). Due to the somewhat ambiguous nature and overlap of these terms within the pharmaceutical industry, caution is ...
From or to a drug trade name: This is a redirect from (or to) the trade name of a drug to (or from) the international nonproprietary name (INN).
