    Big Pain Assays Aren't a Big Pain with the Raptor Biphenyl LC Column

    Featured Application: 231 Pain Management and Drugs of Abuse Compounds in under 10 Minutes by LC-MS/MS Big Pain Assays Aren’t a Big Pain with the Raptor Biphenyl LC Column • 231 compounds, 40+ isobars, 10 drug classes, 22 ESI- compounds in 10 minutes with 1 column. • A Raptor SPP LC column with time-tested Restek Biphenyl selectivity is the most versatile, multiclass-capable LC column available. • Achieve excellent separation of critical isobars with no tailing peaks. • Run fast and reliable high-throughput LC-MS/MS analyses with increased sensitivity using simple mobile phases. The use of pain management drugs is steadily increasing. As a result, hospital and reference labs are seeing an increase in patient samples that must be screened for a wide variety of pain management drugs to prevent drug abuse and to ensure patient safety and adherence to their medication regimen. Thera- peutic drug monitoring can be challenging due to the low cutoff levels, potential matrix interferences, and isobaric drug compounds. To address these chal- lenges, many drug testing facilities are turning to liquid chromatography coupled with mass spectrometry (LC-MS/MS) for its increased speed, sensitivity, and specificity. As shown in the analysis below, Restek’s Raptor Biphenyl column is ideal for developing successful LC-MS/MS pain medication screening methodologies. With its exceptionally high retention and unique selectivity, 231 multiclass drug compounds and metabolites—including over 40 isobars—can be analyzed in just 10 minutes. In addition, separate panels have been optimized on the Raptor Biphenyl column specifically for opioids, antianxiety drugs, barbiturates, NSAIDs and analgesics, antidepressants, antiepileptics, antipsychotics, hallucinogens, and stimulants for use during confirmation and quantitative analyses.

    Hypothalamic Principles Necessary for the Release of Ovulating Hormone from the Adenohypophysis

    EFFECT OF AMINOGLUTETHIMIDE ON REPRODUCTIVE PROCESSES IN FEMALE RATS W. J. EVERSOLE and D. J. THOMPSON Department of Life Sciences, Indiana State University, Terre Haute, Indiana 47809, U.S.A. (Received "òlst January 1974) Summary. Adult female rats injected subcutaneously with 100 mg aminoglutethimide phosphate (AGP)/kg/day for 4 weeks failed to become pregnant when placed in cohabitation with males during the last 2 weeks of the injection period. Lower doses depressed the fertility rate and reduced the litter size: the average litter size of three of eleven rats given 50 mg/kg/day was 4\m=.\7 young and of four of eleven rats given 25 mg was 7\m=.\0 young. Twenty-nine controls averaged 10\m=.\1/litter. Doses of 100 mg AGP/kg/day stopped vaginal cycling, prevented ovulation in adults, and delayed dissolution of the vaginal membrane in pubertal rats. Histological studies of the ovaries from rats with initial ages of 17 or 21 days which were injected with 25 to 100 mg AGP/kg/day for 2 weeks showed an increase in the number and size of vesicular follicles. Treatment of 27-day-old rats with 25 mg/kg/day for 2 weeks reduced the number of CL and three of four rats given 50 mg had ovaries lacking such bodies; all control ovaries in this group contained CL. These findings are taken as evidence that AGP inhibits ovulation but does not prevent follicular maturation. INTRODUCTION Many pharmacological compounds originally developed as anaesthetics, tranquillizers and anticonvulsants modify endocrine structures and functions (see Gaunt, Chart & Renzi, 1965).

    Mechanisms of Action of Antiepileptic Drugs

    Review Mechanisms of action of antiepileptic drugs Epilepsy affects up to 1% of the general population and causes substantial disability. The management of seizures in patients with epilepsy relies heavily on antiepileptic drugs (AEDs). Phenobarbital, phenytoin, carbamazepine and valproic acid have been the primary medications used to treat epilepsy for several decades. Since 1993 several AEDs have been approved by the US FDA for use in epilepsy. The choice of the AED is based primarily on the seizure type, spectrum of clinical activity, side effect profile and patient characteristics such as age, comorbidities and concurrent medical treatments. Those AEDs with broad- spectrum activity are often found to exert an action at more than one molecular target. This article will review the proposed mechanisms of action of marketed AEDs in the US and discuss the future of AEDs in development. 1 KEYWORDS: AEDs anticonvulsant drugs antiepileptic drugs epilepsy Aaron M Cook mechanism of action seizures & Meriem K Bensalem-Owen† The therapeutic armamentarium for the treat- patients with refractory seizures.

There may be a swollen finger with loss of the skin markings-a sort of dactylitis, again serologically negative. (2) Those with a much more severe process which produces loss of movement in the spine and changes in the sacroiliac joints much the same as those in ankylosing spondylitis; unlike ankylosing spondylitis, it produces severe deformity often with ankylosis in peripheral joints. Many of the finger joints become deformed and ankylosed. (3) Those cases indistinguishable from rheumatoid arthritis although the majority are sero-negative. The Stevens Johnson syndrome produces acute effusions, particularly in large joints. It is sometimes associated with the rash of erythema multiforme, always with ulceration in the mouth and genital tract; the mouth ulcers are accompanied by sloughing, unlike those of Beh9et's syndrome which we come to next. BehCet's syndrome, originally described as a combination of orogenital ulceration with relapsing iritis, is now expanded to include skin lesions, other eye lesions, lesions of the central nervous system, thrombophlebitis migrans, and arthropathy (occurring in 64 per cent). The onset is acute, often affecting only a single joint and settling without residual trouble. Choice of drugs in the treatment of rheumatoid arthritis Dr Dudley Hart, M.D., F.R.C.P. (Consultant physician, Westminster Hospital and Medical School) There are many potential drugs for the treatment of rheumatoid disease, but what are we treating in this disorder? Pain in rheumatoid arthritis is but one of the symp- toms.

Typically, neuropathic pain is difficult to manage and, as a result, leads to progression into a chronic condition that is, in many instances, refractory to medical management. Recent Findings Gabapentinoids, belonging to the calcium channel blocking class of drugs, have shown good efficacy in the management of chronic pain and are thus commonly utilized as first-line therapy. Various sodium channel blocking drugs, belonging to the categories of anticonvulsants and local anesthetics, have demonstrated varying degrees of efficacy in the in the treatment of neurogenic pain. Summary Though there is limited medical literature as to efficacy of any one drug, individualized multimodal therapy can provide significant analgesia to patients with chronic neuropathic pain.
