[32] [33] Clindamycin should not be used as an antimalarial by itself, although it appears to be very effective as such, because of its slow action. [32] [33] Patient-derived isolates of Plasmodium falciparum from the Peruvian Amazon have been reported to be resistant to clindamycin as evidenced by in vitro drug susceptibility testing. [34]
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. Cadmium in bone has a biological half-life of about 30 years. Plutonium in bone has a biological half-life of about 100 years.
These modifications do not change their broad antibacterial activity, but do affect pharmacological properties such as half-life and binding to proteins in serum. [ 1 ] Tetracyclines were discovered in the 1940s and exhibited activity against a wide range of microorganisms including gram-positive and gram-negative bacteria , chlamydiota ...
Clindamycin alone has been shown to be efficacious in the treatment of acne, [24] toxic shock syndrome [25] and malaria, [26] and to decrease the risk of premature births in women with bacterial vaginosis. [27]
The β-lactam core structures. (A) A penam.(B) A carbapenam.(C) An oxapenam.(D) A penem.(E) A carbapenem.(F) A monobactam.(G) A cephem.(H) A carbacephem.(I) An oxacephem. This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class.
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods include jumping up and down make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
The rate at which a drug enters into the body for oral and other extravascular routes. 0.693 h −1: Elimination half-life: The time required for the concentration of the drug to reach half of its original value.
