Avenanthramides (AVN) are phenolic alkaloids that are found mainly in oats. They are used in various diary supplements and dermatology products thanks to their anti-inflammatory effects and antioxidant activities.
Calcium is found naturally in the body and is necessary for the normal function of muscles and nerves. It is needed to make the heart work properly and for blood to clot. In injections it is used in the form of calcium gluconate salt. The presented method shows the in-process control of calcium gluconate and stabylizer calcium saccharate in injection solution.
Cephalosporin antibiotic cefazolin sodium is widely used in medicine practice. ARION® Polar C18 column provides perfect resolution factor and peaks symmetry according to the pharmacopoeial method for determination of cefazolin sodium.
Ceramides are a family of fatty acids molecules. They play a role in skin’s barrier function and also promote brain development and maintain cell function. They are widely used as a moisturizer in various cosmetic and personal products. The application shows a sensitive LC/MS method for fast determination of diverse group of ceramides.
Citrate is a chemical stabilizer used in infusion solutions. However, infusion of citrate is responsible for a decrease of arterial blood preessure. So, it is very important to keep optimum concentration in citrate infusion.
Xanax is an benzodiazepine alprazolam-based anxiolitic. Counterfeit Xanax may contain caffeine as a main component, as well as clonazolam and flualprazolam, both of which have a strong sedative effect, are able to cause amnesia, and belong to the group of new psychoactive drugs.
Control of active pharmaceutical ingredients should meet the strict requirements of pharmacopeial monographs. ARION® Plus C18 column provides perfect tailing factor and resolution coefficient according to USP Monograph for codeine phosphate in comparison with competitive’s column.
Dihydrotestosterone (DHT) is an androgenic hormone synthesized primarily in prostate. DHT plays a primary role in the formation of the male genitalia during embryogenesis and it acts as the primary androgen in the prostate and hair follicles in adulthood. In medicine it is used mainly in the treatment of low testosterone levels. ARION® Biphenyl column allows to determine DHT with sufficient tailing factor and resolution coefficient in the complex mixture of excipients in finished dosage form.
The development of the HPLC method for vitamin mixtures in drug products is always challenging, taking into account the requirements of analytical methods in pharmaceutical production. Shown below is a chromatogram of dissolution profile of tablets that contain a mixture of pyridoxine hydrochloride and benfotiamine. ARION® Polar C18 column provides a perfect resolution factor and peaks symmetry in a long sequence of analysis.
Ergot alkaloids are mitotoxins produced by several species of fungies. Many different cereals may become contaminated with ergot alkaloids that cause poisoning in human and animals is known as ergotism. Despite on actions taken in agricultural practice for grain purification, control of the ergot alkaloids is still actual taking into account the low toxicological limits of these mitotoxins.
Flavonoids have antioxidant and antiviral properties and are widely used as drugs and dietary supplements. Sulfation reaction of flavonoid compounds is part of mammalian metabolism. The presented method allows to separate parent compounds luteolin, quercetin, silychristin and their sulfated derivates in enzymatic sulfation reaction mixtures.
The levels of the degradation product, 5-hydroxymethylfurfural (5-HMF), in Dextrose Injection is an important determination in pharmaceutical formulas and pharmacokinetic studies. ASTRA® DM shows better retention for polar compounds.
Ibuprofen is a substance from a group of non-steroidal anti-inflammatory drugs. In order for the drug release to be targeted on the basis of pH change (gradual release for up to 30 days), binding to a polymeric carrier is used.
Ipidacrine is a drug inhibitor of acetylcholinesterase produced for the treatment of memory disorders caused by various diseases. This drug was first synthetized by the National Research Centre for Biologically Active Compounds (Russian Federation).
Opioids can be used in medicine to treat pain and to manage withdrawal symptoms. ASTRA® Phenyl-Hexyl-HE column allows to separate the mixture of opioids with sufficient resolution coefficients in comparison to competitive’s column.
Prostaglandin Active Pharmaceutical Ingredients (APIs) play a significant role in the bodies of humans and animals, and therefore are synthetised for use in ophthalmology, veterinary, and vascular treatment.
A Quinolone antibacterials are drugs used in veterinary medicine to treat bacterial infections. The analysis of residual amounts of drugs in food is important for monitoring the quality control of products of animal origin. This application clearly shows the separation of 16 quinolones using the LC/MS technique.
Tamsulosin hydrochloride is used to treat the symptoms of an enlarged prostate. This drug is an alpha-blocker that works by relaxing the muscles in the prostate and the bladder. Tamsulosin is sold under various trade names, e.g. Flomax, Urimax, Contiflo XL, Mesir LP, Prostanil MR, Tamsin, Fokusin, etc. The application note shows the chromatogram of the determination of the tamsulosin hydrochloride content according to the proprietary method.
Vitamin D is a group of steroids that have various effects on the human body and support the immune system. This application shows LC/MS/MS separation of the hydroxylated and non-hydroxylated forms of vitamin D2 and vitamin D3. The amount of their hydroxylated forms determines the total vitamin D in a blood sample. Non-hydroxylated forms of vitamin D2 and vitamin D3 are important for food analysis. The LC/MS/MS chromatogram shows the separation of all the above mentioned analytes.
Voriconazole and Posaconazole are antifungal drugs that are monitored in plasma and urine. Spiked samples based on a blood plasma from blood donors at transfusion station were used in this application note.
