A new study suggests that acetaminophen, also known as Tylenol, can cause complications in some people over age 65. Drs. Marc Siegel and Macie Smith comment on the findings.
Paracetamol's bioavailability is dose-dependent: it increases from 63 % for 500 mg dose to 89 % for 1000 mg dose. [6] Its plasma terminal elimination half-life is 1.9–2.5 hours, [ 6 ] and volume of distribution is roughly 50 L. [ 132 ] Protein binding is negligible, except under the conditions of overdose, when it may reach 15–21 %. [ 6 ]
If one compared cost per unit (daily tablet) then rosuvastatin was instead 24% cheaper than atorvastatin ($1.44 vs $1.90), and if one compares cost per RDD (recorded daily dose) then rosuvastatin was 26% cheaper than atorvastatin ($1.43 vs $1.93). An erroneous conclusion of a healthcare budget cost increase arises in this case from using cost ...
For the drugs administered by oral and dermal route, the units of threshold dose are mg/kg body-weight/day (dose of the drug in mg per body weight in kg per day) or ppm (parts per million), while the threshold dose of drugs by inhalation delivery has the unit of mg/L 6h/day (amount of drug in mg in 1L of air, for 6 hours per day).

The toxic dose of paracetamol is highly variable. In general the recommended maximum daily dose for healthy adults is 4 grams. [17] [18] Higher doses lead to increasing risk of toxicity. In adults, single doses above 10 grams or 200 mg/kg of bodyweight, whichever is lower, have a reasonable likelihood of causing toxicity.
The U.S. Preventive Services Task Force released a draft recommendation advising against using vitamin D to prevent falls and fractures in people over 60. Pharmacist Katy Dubinsky weighs in.
For many drugs, severe toxicities in humans occur at sublethal doses, which limit their maximum dose. A higher safety-based therapeutic index is preferable instead of a lower one; an individual would have to take a much higher dose of a drug to reach the lethal threshold than the dose taken to induce the therapeutic effect of the drug.
Older adults and people who are immunocompromised (including people with type 1 and type 2 diabetes, people who are pregnant, those with cancer, and more groups) are now encouraged to get two ...
