The possi- bility of malignant disease should be considered in all patents over the age of 40 years who are suspected of having an ulcer buy 75mg doxepin overnight delivery anxiety symptoms women. Gastric and duodenal ulcers are healed by 4-8 weeks treat- ment with H2-receptor antagonists but there is a high rate of relapse (greater than 70% over 2 years) requiring mainte- nance therapy buy 10 mg doxepin free shipping anxiety vs fear. This is undoubtedly cost-efectve compared to the alternatves of long-term maintenance therapy with low-dose H2-receptor antagonists or repeated treatment of recurrent ulcers. Eradicaton regimens are based on a combinaton of an acid-reducing (‘antsecretory’) drug and antbiotcs. The following model eradicaton regimen is suggested on the basis of its efcacy and simplicity (only doses suitable for adults are shown): • Omeprazole 40 mg daily for 1 week plus • Metronidazole 400 mg thrice daily for 1 week plus • Amoxycillin 500 mg thrice daily for 1 week The decision on choosing an eradicaton regimen should take into account local resistance to antbacterials, cost and avail- ability of the necessary drugs. A proton- pump inhibitor such as omeprazole is more efectve but it is also more expensive. It can occur with gastric and duodenal ulceraton and gastric cancer but most commonly it is of uncertain origin. Patents with non-ulcer dyspepsia should be advised to avoid smoking, alcohol and aggravatng foods and to eat small regular meals to aid digeston. Non-ulcer dyspepsia tends to be self-limitng but antacids and H2-receptor antagonists are ofen used to suppress gastric acid. Efectve treatment is important in the presence of severe oesophageal ulceraton to prevent longer term complicatons such as oesophageal stricture and carcinoma. Inital treatment is guided by the severity of symptoms and treatment is then adjusted according to response. H2-receptor antagonists suppress acid secreton and they may relieve symptoms and permit reduc- ton in antacid consumpton. Zollinger-Ellison Syndrome Management of Zollinger-Ellison syndrome requires high dose H2-receptor antagonist treatment. The proton pump inhibitors are more efectve partcularly for cases resistant to other treatment but they are more expensive. Contraindicatons Hypophosphataemia; undiagnosed gastroin- testnal or rectal bleeding; appendicits; por- phyria; hypersensitvity to aluminium salts. Precautons Impaired renal functon and renal dialysis; hepatc impairment (Appendix 7a); constpaton; dehydraton; fuid restricton; gastrointestnal disorders associated with decreased bowel motlity or obstructon; pregnancy (Appendix 7c); interactons (Appendix 6c); oedema, cirrhosis and low sodium diets. Adverse Efects Constpaton, intestnal obstructon (large doses); hypophosphataemia with increased bone resorpton, hypercalciuria and risk of osteomalacia (patents on low phosphate diet or prolonged therapy); hyperalbuminaemia- resultng in osteomalacia, encephalopathy, dementa, microcytc anaemia (in chronic renal failure treated with aluminium hydroxide as phosphate-binding agent); loss of appette. Gastro-oesophageal refux disease Adult: 20 mg twice daily for 6-12 week or up to 40 mg twice daily if there is oesophageal ulceraton. Zollinger-Ellison syndrome Adult: Initally, 20 mg every 6 hr, up to 640 mg daily if necessary. Intravenous Benign gastric and duodenal ulceraton Adult: 20 mg every 12 hr, as an injecton over at least 2 minutes or as an infusion over 15- 30 minutes. Contraindicatons Hypersensitvity Precautons Possibility of gastric malignancy should be excluded, Impaired renal functon, liver cirrhosis, pregnancy (Appendix 7c), lactaton, children and elderly, interactons (Appendix 6c). Adverse Efects Headache, dizziness, constpaton, diarrhoea, nausea, vomitng, anorexia, rash, fatgue, gynaecomasta and impotence. Storage Store protected from light, Tablets to be stored at room temperature, 15 -30⁰C (59- 86⁰F). Precautons Renal impairment; hepatc impairment (Appendix 7a); interactons (Appendix 6c); abdominal pain. Adverse Efects Diarrhoea; in renal impairment- hypermagnesaemia resultng in loss of deep tendon refexes and respiratory depression with other symptoms including nausea, vomitng, fushing of skin, thirst, hypotension, drowsiness, confusion, muscle weakness, bradycardia, coma and cardiac arrest; allergic reacton. Dose Oral Benign gastric and duodenal ulcers: 20 mg once a day for 4 weeks in duodenal ulcers, for 8 weeks in gastric ulcers, Increase to 40 mg in severe case.

Note : The reagent must be prepared afresh using ‘AnalaR-Grade’ dithizone and 1 doxepin 10mg on line anxiety symptoms for years, 10-phenanthroline buy doxepin 10mg line anxiety symptoms vs als, pref- erably taken from a new or recently opened reagent bottle. What is the importance of ‘liquid-liquid extraction’ in the domain of actual estimation? Discuss the Nernst Distribution Law or Partition Law with reference to the theoretical aspects of liquid- liquid extraction support your answer with suitable examples. Expatiate the two following vital aspects of liquid-liquid extraction : (a) Error due to the volume change, (b) Effectiveness of an ‘extraction’. Enumerate the following four cardinal factors which influence the solvent extraction mostly : (i) Effect of temperature and inert solutes, (ii) Effect of pH on extraction, (iii) Effect of ion-pair formation, and (iv) Effect of synergistic extraction Provide suitable examples wherever possible to make your explanation more plausible and understandable. What do you understand by the term ‘free energy’ of the system between two immiscible solvents? Describe the theory and methodology for the assay of Cu(I) as its neo-cuprin complex. Kirchner in 1950 was the first who used adsorption chromatography on impregnated glass-plate coated with silicic acid or alumina. It may be emphasized, however, that Egon Stahl’s fundamental work stands as a landmark in the world-wide acceptance of this new technique in the laboratory. Later on, Stahl in 1958, introduced a standard equipment for preparing uniform thin-layers of known thickness, which eventually led to the ultimate acceptance of this new technique as an additional modern tool for analytical chemistry. This is invariably referred to in various literature as : ‘open-column chromatography’; ‘drop chro- matography’ ; ‘strip-chromatography’ ; ‘spread-layer chromatography’ ; ‘surface chromatography’. Subsequently, the mobile phase is permitted to move across the surface of the plate (usually by capillary action) and the chromatographic phenomenon may solely depend upon adsorption, partition, or a combination of both, depending on the adsorbent, its treatment, and the nature of the solvents employed. The inert solid supports invariably employed are, namely : alumina, silica gel, kieselguhr and cellulose, to these may be added appropriate substances, for instance : calcium sulphate (gypsum) so as to provide adequate adhesion to the solid support, example : silica gel-G (G-stands for gypsum). The prepared layer may be impregnated with suitable materials to achieve specific purpose, namely : (i) Buffering materials : To afford acidic, basic or neutral layers, (ii) Silver nitrate : To modify its characteristics e. Hence, it has a positive edge over paper and column chromatography which normally takes several hours or days. Various means have been put forward to apply thin layers of powdered or their suspen- sions or their slurries to the carrier plates with a view to achieve an uniform layer throughout the length of the plates. These are namely : (a) Pouring of Layers : In order to obtain layers of equal thickness, a measured amount of the suspen- sion or slurry is placed on a given-size plate that is rested on an absolutely labelled surface. The plate is subsequently tipped backward and forward to permit the slurry (or suspension) to spread uniformly on the surface of the plate. Disadvantages : There are mainly two major disadvantages of this technique, namely : (i) Non-uniformity of layers on a single-plate, and (ii) Variation observed from one plate to the other was significant. Belgian Patent No : 625012 : It essentially consists of spraying either molten or partially molten absorbent onto a glass plate, for instance : an alumina film prepared by melting and aluminium rod with an oxyacetylene flame and subsequently spraying the molten adsorbent onto a glass plate. This technique termed as ‘spreading’ usually yields uniform thin layers on the glass plates. Kirchner’s* technique essentially consists of : • selecting uniform surfaced glass plates, • placing them between glass or metal guides which are thicker than glass plates by the amount that is desired for the adsorbent layer, and • spreading the slurry on the glass plate with the help of a glass rod. Egon Stahl’s apparatus exclusively designed for the application of thin-adsorbent layers which broadly comprises of two major parts, namely : (i) Aligning Tray : It is a tray on which the glass plates are placed in a series or in-a-line, and (ii) Spreader : It holds the spreading mixture (as a slurry or suspension) and applies it uniformly in a thin-layer.
