Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
Ceftriaxone, sold under the brand name Rocephin, is a third-generation cephalosporin antibiotic used for the treatment of a number of bacterial infections. [4] These include middle ear infections, endocarditis, meningitis, pneumonia, bone and joint infections, intra-abdominal infections, skin infections, urinary tract infections, gonorrhea, and pelvic inflammatory disease.

The general formula of a phosphoric acid is H n−2x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure; that is, the minimum number of bonds that would have to be broken to eliminate all cycles.
Since August 2012, the third-generation cephalosporin, ceftriaxone, is the only recommended treatment for gonorrhea in the United States (in addition to azithromycin or doxycycline for concurrent Chlamydia treatment). Cefixime is no longer recommended as a first-line treatment due to evidence of decreasing susceptibility. [30] Ceftriaxone ...
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
General ester of phosphonic acid; in fact, the phosphorus has a formal charge of +1, the oxygen above it has a formal charge of −1, and the bond between them is single. In organic chemistry , phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR) 2 groups , where R is an organic group ( alkyl , aryl ).
Reduction of this compound with alcohols gives the vanadium(IV) phosphates. These compounds are catalysts for the oxidation of butane to maleic anhydride. A key step in the activation of these catalysts is the conversion of VO(HPO 4)•0.5H 2 O to the pyrophosphate (VO) 2 (P 2 O 7). This material (CAS#58834-75-6) is called vanadyl pyrophosphate ...
The H+/2e − ratios of the three major respiratory complexes are generally agreed to be 4, 4, and 2 for Complexes I, III, and IV respectively. [7] The H + /O ratio thus depends whether the substrate electrons enter at the level of NADH (passing through all three for 10 H + /2e −) or ubiquinol (passing through only complexes III and IV for 6H ...
