Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Leflunomide belongs to the new class of immunomodulating drugs with inflammatory and immunomodulating properties. It has been investigated for application in transplantation procedures. It is also an anti-rheumatic drug (DMARD) used to treat rheumatoid arthritis (RA). Its mode of action involves the inhibition of T-cell proliferation after converting to its active metabolite i.e. A771726 in humans.

Letrozole may be used as a pharmaceutical reference standard for the determination of the analyte in biological/environmental samples and pharmaceutical formulations by various chromatography techniques.

Letrozole is a third generation nonsteroidal aromatase inhibitor. It is a competitive inhibitor of the aromatase enzyme system and thus inhibits the conversion of androgens to estrogens. Letrozole inhibits the aromatase enzyme by competitively binding to the heme of the cytochrome P450 subunit of the enzyme, resulting in a reduction of estrogen biosynthesis in all tissues.

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Shows both immunostimulant and immunosuppressant effects, depending on several controllable factors. Very effective in treatment of ascariasis (hookworm infestation). Useful in chemotherapy of colorectal cancers, possibly due to its stimulation of IL-1 production and direct activation of macrophages.

Levitiracetam may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography techniques and spectrofluorimetric technique.

Levetiracetam is a pyrrolidine with antiepileptic activity. Stereoselective binding of levetiracetam was confined to synaptic plasma membranes in the central nervous system with no binding occurring in peripheral tissue. Levetiracetam inhibits burst firing without affecting normal neuronal excitability, which suggests that it may selectively prevent hyper-synchronization of epileptiform burst firing and propagation of seizure activity.

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Carnitine is a quaternary amine that occurs naturally in most mammalian tissue. It is present in relatively high concentrations in skeletal muscle and heart where it is involved in regulating energy metabolism. It shifts glucose metabolism from glycolysis to glycogen storage and enhances the transport of long chain fatty acids into the mitochondria where they are oxidized for energy production.

Linezolid is an oxazolidinone antimicrobial. It binds to a site on the bacterial 23S ribosomal RNA of the 50S subunit and prevents the formation of a functional 70S initiation complex, thus inhibiting bacterial mRNA translation. Linezolid is also a weak, reversible, nonselective inhibitor of monoamine oxidase.
