Modified-release dosage is a mechanism that (in contrast to immediate-release dosage) delivers a drug with a delay after its administration (delayed-release dosage) or for a prolonged period of time (extended-release [ER, XR, XL] dosage) or to a specific target in the body (targeted-release dosage). [1]
This allows for much more precise drug delivery over an extended period of time, which results in much more predictable pharmacokinetics. However, osmotic release systems are relatively complicated, somewhat difficult to manufacture, and may cause irritation or even blockage of the GI tract due to prolonged release of irritating drugs from the ...
Metformin has an oral bioavailability of 50–60% under fasting conditions, and is absorbed slowly. [9] [130] Peak plasma concentrations (C max) are reached within 1–3 hours of taking immediate-release metformin and 4–8 hours with extended-release formulations.
Further, metformin comes in the form of immediate-release tablets, extended-release tablets, and as a liquid. Each type of metformin has different requirements in terms of when and how to take it:
Insulins are typically characterized by the rate at which they are metabolized by the body, yielding different peak times and durations of action. [4] Faster-acting insulins peak quickly and are subsequently metabolized, while longer-acting insulins tend to have extended peak times and remain active in the body for more significant periods. [5]
The first patient in the U.S. was hospitalized with "severe" bird flu. Here's what you should know about symptoms, according to an infectious disease expert.

[1] [2] It is regarded as a second-line option compared to metformin, due to metformin's well-established safety and efficacy. [1] Use of glimepiride is recommended in conjunction with lifestyle modifications such as diet and exercise. [1] It is taken by mouth, [1] reaching a peak effect within three hours and lasting for about a day. [1]
