Pharmaceuticals amoxicillin

Pharmaceuticals. -Hydroxybenzaldehyde is often a convenient intermediate in the manufacture of pharmaceuticals (qv). For example, 2-(p-hydroxyphenyl)glycine can be prepared in a two-step synthesis starting with -hydroxybenzaldehyde (86). This amino acid is an important commercial intermediate in the preparation of the semisynthetic penicillin, amoxicillin (see ANTIBIOTICS, P-LACTAMs). Many cephalosporin-type antibiotics can be made by this route as well (87). The antiemetic trimethobenzamide [138-56-7] is convenientiy prepared from -hydroxybenzaldehyde (88) (see Gastrointestinal agents). 

The second most important group of immobilized enzymes is stiU the penicillin G and V acylases. These are used in the pharmaceutical industry to make the intermediate 6-aminopenici11anic acid [551-16-6] (6-APA), which in turn is used to manufacture semisynthetic penicillins, in particular ampicilHn [69-53-4] and amoxicillin [26787-78-0]. This is a remarkable example of how a complex chemical synthesis can be replaced with a simple enzymatic one ... 

For certain substances it is generally accepted that in conventional orcil pharmaceutical formulations they do not cause bioequivalence problems. That is why the MEB does not consider it necessary to perform and submit bioequivalence research for the following 19 substances amoxicilline, dextromethorfan, diazepam, doxycycline, potassiumfenoxymethylpenicillin, flunarizine, indometacine, isosorbide-5-mononitrate, lorazepam, lormetazepam, metoprolol, naproxen, nitrazepam, oxprenolol, paracetamol, pindolol, piroxicam, salbutamol, temazepam. According to the MEB there is enough evidence present in literature to prove that there is no problem with the bioequivalence.

Amoxicillin is a broad spectrum penicillin antibiotic that was first marketed by Beecham Pharmaceuticals in 1972. A co-formulation with potassium clavulanate, marketed by Beecham in 1981, extended the antibacterial spectrum to include (3-lactamase producing organisms. Amoxicillin is on the World Health Organisation s list of essential drugs.

The technique of x-ray diffraction is exceedingly important to pharmaceutics because it represents the primary method for obtaining fundamental structural information on crystalline substances. For example, it is only by pure coincidence that two compounds form crystals in which the three-dimensional spacing of planes is identical in all directions. One such example is provided by the trihydrate phases of ampicillin and amoxicillin, but such instances are uncommon. Typical applications of x-ray diffraction methodology include the determination of crystal structures, evaluation of polymorphism and solvate structures, evaluation of degrees of crystallinity, and the study of phase transitions.

The determination of amoxicilline, ciprofloxacin, and piroxicam in bulk and pharmaceutical preparations has been performed by combining the oxidation character of Fe(III) with the chelation property of Fe(II), affording highly colored complexes. The reagent solutions are (1) a mixture of 1,10-phenanthroline and iron(III) ammonium sulfate in hydrochloride medium and (2) 2,2 -bipyridyl and iron(III) ammonium sulfate in hydrochloride medium. The resulting Fe(II) concentration, proportional to the amount of drug present, is monitored by the measurement of absorbances of tris(o-phenanthro-line) iron(U) or tris (bipyridyl) iron(II) complexes at 510 and 522 nm, respectively.
