Amlodipine has been studied in healthy volunteers following oral administration of 14 C-labelled drug. [53] Amlodipine is well absorbed by the oral route with a mean oral bioavailability around 60%; the half-life of amlodipine is about 30 h to 50 h, and steady-state plasma concentrations are achieved after 7 to 8 days of daily dosing.

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 ...
Polonium in the body has a biological half-life of about 30 to 50 days. Caesium in the body has a biological half-life of about one to four months. Mercury (as methylmercury) in the body has a half-life of about 65 days. Lead in the blood has a half life of 28–36 days. [29] [30] Lead in bone has a biological half-life of about ten years.
Anti-obesity medication or weight loss medications are pharmacological agents that reduce or control excess body fat. These medications alter one of the fundamental processes of the human body , weight regulation, by: reducing appetite and consequently energy intake , increasing energy expenditure , redirecting nutrients from adipose to lean ...

In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. [2]
A Stanford Medicine study found that human aging speeds up at 44 and 60. Here, doctors share how to quell it by cutting alcohol, strength training, and more. ... didn’t shift in numbers in a ...
However, their mean body fat percentage, 14%, is well within what is considered a healthy range. [22] The preferred obesity metric in scholarly circles is the body fat percentage (BF%) [citation needed] - the ratio of the total weight of person's fat to his or her body weight, and BMI is viewed merely as a way to approximate BF%.
