Inital Management: Oxygen should be given to all patents buy 100 mcg entocort with amex, except those with severe chronic obstructve pulmonary disease discount 100 mcg entocort free shipping. Pain and anxiety are relieved by slow intravenous injecton of an opioid analgesic such as morphine purchase entocort 100 mcg line. Metoclopramide may also be given by intramuscular injecton to prevent and treat nausea and vomitng caused by morphine. Acetylsalicylic acid 150-300 mg by mouth (preferably chewed or dispersed in water) is given immediately for its antplatelet efect. Thrombolytc drugs such as streptokinase help to restore perfusion and thus relieve myocardial ischaemia; they should ideally be given within 1 h of infarcton (use afer 12 h requires specialist advice). Early administraton of beta-blockers such as atenolol have been shown to reduce both early mortality and the recur- rence rate of myocardial infarcton; inital intravenous admin- istraton is followed by long-term oral treatment (unless the patent has contraindicatons). If arrhythmias occur, they should be treated aggressively, but the likelihood decreases rapidly over the frst 24 h afer infarcton. Ventricular fbrillaton should be treated imme- diately with a defbrillator; if this is inefectve alone, the antarrhythmic drug lidocaine should be given. Long-term Management Acetylsalicylic acid should be given to all patents in a dose of 75-150 mg daily by mouth, unless it is contraindicated. Treatment with beta-blockers should be contnued for at least 1 year and possibly for up to 3 years. Stroke: Stroke (cerebrovascular accident) may be ischaemic or haem- orrhagic; precise diagnosis is essental, as management for the two types of stroke is quite diferent. Primary preventon of both types of stroke includes reducton of high blood pressure, stopping smoking, weight reducton and cholesterol reducton. Atrial fbrillaton, acute myocardial infarcton and valvular disease may produce embolism and ischaemic stroke. Prophylaxis in patents at risk of ischaemic stroke includes oral antcoagulants such as warfarin and antplatelet drugs such as acetylsalicylic acid. Treatment of acute ischaemic stroke includes use of acetylsalicylic acid, antcoagulants such as heparin and of thrombolytcs, such as streptokinase. Long-term therapy with acetyl- salicylic acid reduces the risk of having another stroke. Antplatelet and thrombolytc drugs are not used in the management of haemorrhagic stroke, as they may exacerbate bleeding. Acetylsalicylic acid is normally given for at least one year afer coronary artery bypass surgery. It is also given to patents with prosthetc heart valves who have had cerebral embolism despite warfarin treatment.

Manufactured catecholamines have a short duration of action entocort 100mcg, which can limit their therapeutic usefulness trusted 100mcg entocort. Drug interactions Drug interactions involving catecholamines can be serious buy generic entocort 100 mcg line, result- ing in hypotension, hypertension, arrhythmias, seizures, and high blood glucose levels in diabetic patients. These patients may require an increased dose of insulin or oral antidiabetic agents. Adverse reactions to catecholamines Adverse reactions to catecholamines can include: • restlessness • asthmatic episode • dizziness • headache • palpitations • cardiac arrhythmias • hypotension • hypertension and hypertensive crisis • stroke • angina • increased blood glucose levels • tissue necrosis and sloughing (if a catecholamine given I. Increased risk of adverse effects, such as hypertension, may occur when adrenergic drugs are given with other drugs that can cause hypertension. Absorption and distribution Absorption of the noncatecholamines depends on the administra- tion route: • Inhaled drugs, such as albuterol, are absorbed gradually from the bronchi and result in lower drug levels in the body. Excretion Noncatecholamines and their metabolites are excreted primarily in urine. Some, such as inhaled albuterol, are excreted within 24 hours; others, such as oral albuterol, within 3 days. Acidic urine increases excretion of many noncatecholamines; alkaline urine slows excretion. Pharmacodynamics Noncatecholamines can be direct-acting, indirect-acting, or dual- acting (unlike catecholamines, which are primarily direct-acting). Those that selectively stimulate beta2 re- ceptors include albuterol, isoetharine, metaproterenol, and terbu- taline. Pharmacotherapeutics Noncatecholamines stimulate the sympathetic nervous system, producing a variety of effects in the body. Phenylephrine, for ex- ample, causes vasoconstriction and is used to treat hypotension in cases of severe shock. Adverse reactions to noncatecholamines Adverse reactions to noncate- • hypertension or hypotension cholamine drugs may include: • palpitations • headache • bradycardia or tachycardia • restlessness • irregular heart rhythm • anxiety or euphoria • cardiac arrest • irritability • cerebral hemorrhage • trembling • tingling or coldness in the arms • drowsiness or insomnia or legs • light-headedness • pallor or flushing • incoherence • angina. Here are a few examples of drugs that interact with noncatechol- amines: • Anesthetics (general), cyclopropane, and halogenated hydrocar- bons can cause arrhythmias. Hypotension can also occur if these drugs are taken with noncatecholamines that exert predominantly beta2 activity, such as terbutaline. When taken with other non- catecholamines, oxytocic drugs can cause hypertensive crisis or a stroke. Their action at these sites can be exerted by: • interrupting the action of adrenergic (sympathomimetic) drugs • reducing available norepinephrine • preventing the action of cholinergic drugs. Classified information Adrenergic blocking drugs are classified according to their site of action as: • alpha-adrenergic blockers (or alpha blockers) • beta-adrenergic blockers (or beta blockers). Alpha-adrenergic blockers Alpha-adrenergic blockers work by interrupting the actions of the catecholamines epinephrine and norepinephrine at alpha recep- tors. This results in: • relaxation of the smooth muscle in blood vessels • increased dilation of blood vessels Let’s face it—the • decreased blood pressure. A mixed bag Ergotamine is a mixed alpha agonist and antagonist; at high doses, it acts as an alpha-adrenergic blocker. Pharmacokinetics The action of alpha-adrenergic blockers in the body isn’t well un- derstood. Most of these drugs are absorbed erratically when ad- ministered orally, and more rapidly and completely when adminis- tered sublingually. Pharmacodynamics Alpha-adrenergic blockers work in one of two ways: • They interfere with or block the synthesis, storage, release, and reuptake of norepinephrine by neurons. Not very discriminating Alpha-adrenergic blockers include drugs that block stimulation of alpha1 receptors and that may block alpha2 receptors. Reducing resistance Alpha-adrenergic blockers occupy alpha receptor sites on the smooth muscle of blood vessels. How alpha-adrenergic blockers affect peripheral blood vessels By occupying alpha receptor sites, alpha-adrenergic blocking One result: Orthostatic hypotension drugs cause the blood vessel walls to relax. This leads to dila- These effects can cause orthostatic hypotension, a drop in tion of the blood vessels and reduced peripheral vascular re- blood pressure that occurs when changing position from lying sistance (the pressure that blood must overcome as it flows in down to standing. The decreased periph- eral vascular resistance (resistance to blood flow) helps to de- crease blood pressure. Alpha-adrenergic blockers cause a The therapeutic effect of an alpha-adrenergic blocker depends on small change in blood the sympathetic tone (the state of partial constriction of blood pressure if you’re lying vessels) in the body before the drug is administered. For instance, down… when the drug is given with the patient lying down, only a small change in blood pressure occurs. Patient up, pressure down On the other hand, when a patient stands up, norepinephrine is re- leased to constrict the veins and shoot blood back up to the heart. If the patient receives an alpha-adrenergic blocker, however, the veins can’t constrict and blood pools in the legs. This drop in blood pressure that occurs when a person stands up is called or- thostatic hypotension. Pharmacotherapeutics Because alpha-adrenergic blockers cause smooth muscles to relax and blood vessels to dilate, they increase local blood flow to the skin and other organs and reduce blood pressure. As a result, they’re used to treat: …when you stand, • benign prostatic hypertrophy the drug prevents • hypertension your veins from • peripheral vascular disorders (diseases of the blood vessels of constricting. Drug interactions Many drugs interact with alpha-adrenergic blockers, producing a synergistic, or exaggerated, effect. These interactions can occur when these drugs are taken with ergoloid mesylates and ergotamine: • Caffeine and macrolide antibiotics can increase the effects of ergotamine. Adverse reactions to alpha- adrenergic blockers Most adverse reactions associated with alpha-adrenergic blockers are caused primarily by dilation of the blood vessels. They include: • orthostatic hypotension or severe rebound hypertension • bradycardia or tachycardia • edema • difficulty breathing • light-headedness • flushing • arrhythmias • angina • heart attack • spasm of blood vessels in the brain • a shocklike state. Non- selective beta-adrenergic blockers affect: • beta1 receptor sites (located mainly in the heart) • beta2 receptor sites (located in the bronchi, blood vessels, and uterus).

Pipette 50 ml into a conical flask cheap 100mcg entocort with visa, cool to below 15°C (in ice-bath) and titrate gradually with 0 discount entocort 100 mcg without prescription. Theory : The estimation is based on the fact that isocarboxazid undergoes rapid cleavage in acidic medium to produce benzylhydrazine cheap entocort 100mcg line. The latter reacts with nitrous acid to yield the corresponding diazonium salt quantitatively. The contents of the flask are shaken thoroughly and continuously until a distinctly visible blue colour is obtained when a drop of the titrated solution is placed on a starch-iodide paper 5 minutes after the last addition of the 0. Why is it necessary to perform ‘sodium nitrite titrations’ invariably in an acidic medium? Based on the ‘diazotization reaction’ how would you carry out the assay of the following ‘drug substances’ : (i) Isocarboxazid (ii) Phthalylsulphathiazole (iii) Sulphamelthoxazole (iv) Primaquine phosphate. These products of reaction are produced quantitatively and are mostly water-insoluble in characteristics ; and more interestingly they take place in an acidic medium. As it has been discussed earlier, iodine cannot be used directly as an oxidizing agent in such type of assays, whereas the liberated iodine quantitatively produced by the oxidation of iodide with bromine (excess) may be assayed by titrating against sodium thiosulphate solution. Procedure : Weigh 3 g of potassium bromate and 15 g of potassium bromide in a beaker and dissolve with water. Add to it 5 ml of hydrochloric acid, moisten the glass-stopper with water and insert the stopper in the flask. Now, add 5 ml of potassium iodide solution, again lace the stopper and allow the resulting mixture to stand for 5 minutes in the dark. Warm the solution to about 75°C, add 2 drops of methyl orange solution and continue the titration gradually while swirling the contents of the flask thor- oughly after each addition. If the colour of the solution is still red, continue the titration dropwise and with constant stirring until the red colour of the indicator is discharged completely. Repeat an operation without the pharmaceutical substance (blank titration) ; thus the difference between the titrations represents the amount of bromine required by the ethacrynic acid. Cognate Assays A number of pharmaceutical substances may be determined quantitatively by titration with bromine as given in Table 13. Transfer the solution quantitatively into a 1 litre volumetric flask and make up the volume to the mark. Mix the contents thoroughly and allow it to stand for 5 minutes with its stopper in position. Carry out a blank run using the same quantities of the reagents and incorporate the necessary corrections, if any. Mephenesin Theory : Mephenesin undergoes oxidation with bromine to yield a dibromo derivative as expressed in the following equation : BrO – + 6e + 6H+ → Br– + 3H O... Phenol Theory : Phenol interacts with bromine whereby the former undergoes bromination to yield a water- insoluble 2, 4, 6-tribromophenol. Set it aside in a dark place for 20 minutes while shaking the contents frequently in between. Carry out a blank titration simultaneously and incorporate any necessary correction, if required. Cognate Assays A few other pharmaceutical substances may also be assayed by titrating with 0. Under appropriate experimental parameters the iodate reacts quantitatively with both iodides and iodine. It is, however, interesting to observe here that the iodate titrations may be carried out effectively in the presence of saturated organic acids, alcohol and a host of other organic substances. Since, the normality of iodate solution varies significantly depending on the nature of the reaction, therefore, in usual practice standard iodate solutions of known molarity are used. In a situation, whereby excess of potassium iodate is employed, any I– formed [Eq. Interestingly, at higher concentrations of hydrochloric acid, both the iodide and iodine obtained as reduction products of iodate [Eqs. Iodine is liberated at the initial stages of the titration which renders the chloroform layer coloured. At that material point when all the reducing agent under estimation has been duly oxidized, the iodate completes the oxidation of iodine and iodide to I+, and hence the colour from the chloroform layer disappears. Shake the contents thoroughly, allow to separate and collect the chloroform layer in another separating funnel. Treat the aqueous layer with 3 further quantities each of 10 ml of chloroform and discard the chloroform layer. Add 2 ml of chloroform and continue the titration until the chlorofonn layer becomes colourless. Potassium Iodide Theory : The iodine monochloride method described earlier employing standard potassium iodate is the basis for the official assay of potassium iodide. Vigorous shaking is a prime requirement, as the end-point is approached in this assay, because of the fact that both iodine and iodate in different phases attribute a heterogeneous medium. Add the last portion of the iodate solution carefully and dropwise while shaking the contents of the flask vigorously and continuously. Cognate Assays A host of other pharmaceutical substances, namely : cetrimide, hydralazine hydrochloride, phenylhydrazine hydrochloride may be assayed by titration with potassium iodate as mentioned in Table : 13. Why is ‘bromine’ preferred to ‘iodine’ in redox methods for the assay of pharmaceutical organic substances?
