Patents taking isosorbide dinitrate for the long-term management of angina may ofen develop tolerance to the antanginal efect; this can be avoided by giving the second of 2 daily doses of longer-actng oral presentatons afer an 8-h rather than a 12-h interval, thus ensuring a nitrate-free interval each day. Metoprolol* Pregnancy Category-C Schedule H Indicatons Supraventricular arrhythmia, angina pectoris, hypertension, myocardial infarcton; migraine prophylaxis; hyperthyroidism, heart failure. Intravenous injecton Arrhythmia: up to 5 mg at a rate of 1 to 2 mg per min, repeated afer 5 min if necessary (max dose 10 to 15 mg). Beta-blockers, including those considered to be cardioselectve, should not be given to patents with a history of asthma or bronchospasm. However, in rare situatons where there is no alternatve a cardioselectve beta-blocker is given to these patents with extreme cauton and under specialist supervision. Adverse Efects Gastro-intestnal disturbances; bradycardia, heart failure, hypotension, conducton disorders; peripheral vasoconstricton (including exacerbaton of intermitent claudicaton and Raynaud’s phenomenon); bronchospasm; dyspnoea; headache; fatgue; sleep disturbances; paraesthesia; dizziness; vertgo; psychosis; sexual dysfuncton; purpura; thrombocytopenia; visual disturbances; exacerbaton of psoriasis; alopecia; rarely, rashes and dry eyes (reversible on withdrawal); on infusion venous irritaton and thrombophlebits; agranulocytosis; hyperglycemia; myocardial depression.

Prophylaxis afer myocardial infarcton: 40 mg 4 tmes daily for 2 to 3 days, then 80 mg twice daily beginning 5 to 21 days afer infarcton. Beta-blockers, including those considered to be cardioselectve, should not be given to patents with a history of asthma or bronchospasm. However, in rare situatons where there is no alternatve a cardioselectve beta-blocker is given to these patents with extreme cauton and under specialist supervision. Adverse Efects Gastro-intestnal disturbances; bradycardia; heart failure, hypotension, conducton disor- ders; peripheral vasoconstricton (including exacerbaton of intermitent claudicaton and Raynaud’s phenomenon); bronchospasm; dyspnoea; headache; fatgue; sleep distur- bances; paraesthesia; dizziness; vertgo; psychosis; sexual dysfuncton; purpura; thrombocytopenia; visual disturbances; exacerbaton of psoriasis; alopecia; rarely, rashes and dry eyes (reversible on withdraw- al); on infusion venous irritaton and throm- bophlebts; eosinophilia; hyperglycemia; cardiogenic shock; visual hallucinatons. A proposal to include such a product in a natonal list of essental drugs should be supported by adequate documentaton Dose Oral Adult- 80 to 120 mg 3 tmes daily (120 mg 3 tmes daily usually required in Prinzmetal angina). Elderly- Paroxysmal tachyarrhythmias: 5 to 10 mg over 3 min, further 5 mg may be given afer 5 to 10 min if required. Contraindicatons Hypotension, bradycardia, second- and third-degree atrioventricular block, sinoatrial block, sick sinus syndrome; cardiogenic shock; history of heart failure or signifcantly impaired lef ventricular functon (even if controlled by therapy); atrial futer or fbrillaton complicatng Wolf-Parkinson- White syndrome; porphyria; platelet dysfuncton. Precautons First-degree atrioventricular block; kidney impairment; cirrhosis patents; acute phase of myocardial infarcton (avoid if bradycardia, hypotension, lef ventricular failure); hepatc impairment (Appendix 7a); children (special- ist advice only); lactaton; pregnancy (Appen- dix 7c); interactons (Appendix 6b, 6c). Antarrhythmic drugs must be used cautously since most drugs that are efectve in treatng arrhythmias can provoke them in some circumstances; this arrhythmogenic efect is ofen enhanced by hypokalaemia. When antarrhythmic drugs are used in combinaton, their cumulatve negatve inotropic efects may be signifcant, partcularly if myocardial functon is impaired. Atrial Fibrillaton: The increased ventricular rate in atrial fbrillaton can be controlled with a beta-adrenoceptor antagonist (beta-blocker) or verapamil. Digoxin is ofen efectve for controlling the rate at rest; it is also appropriate if atrial fbrillaton is accompa- nied by congestve heart failure. Intravenous digoxin is occa- sionally required if the ventricular rate needs rapid control. If adequate control at rest or during exercise cannot be achieved readily verapamil may be introduced with digoxin, but it should be used with cauton if ventricular functon is impaired. Antcoagulants are indicated especially in valvular or myocardial disease and in the elderly. If atrial fbrillaton began within the previous 48 h and there does not appear to be a danger of thromboembolism, antarrhythmic drugs, such as procainamide or quinidine, may be used to terminate the fbrillaton or to maintain sinus rhythm afer cardioversion. Rever- sion to sinus rhythm is best achieved by direct current elec- trical shock. If the arrhythmia is long-standing, treatment with an antcoagulant should be considered before cardioversion to prevent emboli. Intravenous verapamil reduces ventricular fbrillaton during paroxysmal (sudden onset and intermitent) atacks of atrial futer. An inital intravenous dose may be followed by oral treatment; hypotension may occur with high doses. If the futer cannot be restored to sinus rhythm, antarrhythmics such as quinidine can be used. Failing this, intrave- nous injecton of a beta-adrenoceptor antagonist (beta-blocker) or verapamil may be efectve. Verapamil and a beta-blocker should never be administered concomitantly because of the risk of hypotension and asystole.

This risk can be eliminated by treatment with a progestational agent for up to 14 days a month best cialis 5mg. The vaginal delivery of a polycarbophil gel loaded with progesterone has been shown to allow the extended vaginal delivery of the drug for 2–3 days from a single dose and protect the endometrium against cancer purchase cialis 2.5mg line. Low serum levels of progesterone were detected after vaginal delivery, which corresponds to fewer side-effects. A commercial progesterone-loaded polycarbophil gel preparation for intravaginal delivery, Crinone, has recently been launched. Smart hydrogel Smart hydrogel preparations, comprising poly(acrylic acid) and a poloxamer (see Section 16. The temperature- dependent gelling of the system helps to prevent leak-back and provides sustained release properties. Smart hydrogel preparations containing estradiol have shown similar bioavailability to a commercial vaginal cream and suppository, even though the gel contained only 20% of the relative estradiol dose. However, the low and erratic bioavailability of biopharmaceuticals via this route necessitates the use of absorption enhancers. Until safe, non-toxic absorption enhancers can be found, the route is of limited potential. A further major limitation of this route is the lack of reproducibility resulting from cyclic changes in the reproductive system. Finally, no matter what degree of optimization can be achieved via this route, it can only ever benefit approximately 50% of the population! Mucosal penetration enhancers for facilitation of peptide and protein drug absorption. Give examples of the classes of the pharmaceutical agents which are presently marketed as topical formulations for vaginal administration. Which other epithelial membrane has a structure most similar to that of the vaginal epithelium? During which phase of the menstrual cycle is the vaginal epithelia thickest and the epithelial tight junctions most cohesive, thereby reducing the absorption of hydrophilic compounds via the paracellular route? Which of the following do not leak through the intercellular channels of vaginal epithelium at the late luteal phase and early follicular phase? What factor controls the pH in the vaginal lumen at between pH 4 and pH 5, preventing the proliferation of pathogenic bacteria? Describe the types of absorption enhancers under development for use in vaginal route. Describe the possible reasons for enhanced vaginal vaccination using microparticulate systems. Research has recently been directed towards the development of alternatives to the parenteral route, such as the transdermal, nasal and other routes thus far discussed in this book, for the systemic delivery of such drugs. However, unlike the other routes described in this text, ophthalmic drug delivery is used only for the treatment of local conditions of the eye and cannot be used as a portal of drug entry to the systemic circulation. Nevertheless, this route warrants study within the general context of drug delivery and 299 targeting, as the local delivery of drugs to their site of action represents a form of drug targeting, reducing the dose needed to produce a pharmacological effect and also minimizing side-effects. Furthermore, significant advances have been made to optimize the localized delivery of medication to the eye, so that the route is now associated with highly sophisticated drug delivery technologies; some of these technologies are unique to the eye and many are also found in the other delivery routes. The eye is a sensory organ, prone to a wide variety of diseases which may be of a systemic origin, such as diabetes or hypertension, or peculiar to the eye, such as glaucoma, cataract and macular degeneration. Furthermore, since the eye is located on the surface of the body, it is also easily injured and infected. According to the location of diseases, ocular disorders are grouped as periocular and intraocular conditions. Periocular diseases include: Blepharitis An infection of the lid structures (usually by Staphylococcus aureus) with concomitant seborrhea, rosacea, a dry eye and abnormalities of the meibomein glands and their lipid secretions. Conjunctivitis The condition when redness of the eye and the presence of a foreignbody sensation are evident. There are many causes of conjunctivitis, but the great majority are the result of acute infection or allergy. Keratitis The condition in which patients have a decreased vision, ocular pain, red eye, and often a cloudy/opaque cornea. Trachoma This is caused by the organism Chalmydia trachomatis; it is the most common cause of blindness in North Africa and the Middle East. Dry eye If for any reason the composition of tears is changed, or an inadequate volume of tears is produced, the symptom of dry eye will result. Dry eye conditions are not just a cause for ocular discomfort, but can also result in corneal damage. Periocular diseases such as these are relatively easily treated using topical formulations. Intraocular conditions are more difficult to manage and include intraocular infections: i. Such infections carry a high risk for damage to the eye and also afford the possibility of spread of infection from the eye into the brain.

The elevated levels are due to hepatic injury buy 2.5 mg cialis with mastercard, and (5) Drugs that interfere with the assay are trusted 10 mg cialis, namely : (a) phenylazopyridine hydrochloride—a coloured drug, (b) azo-compound forming medicinals, and (c) degradation product of novobiocin. Cholesterol Cholesterol interacts with glacial acetic acid and acetic anhydride to result into the formation of a coloured product whose absorption is measured at 630 nm and this is found to be directly proportional to the level of cholesterol present in the serum. Profile of Cholesterol Levels (1) Normal total cholesterol level is 200 mg per 100 ml, (2) Increased cholesterol levels in serum are found in patients suffering from chronic hepatitis, atherosclerosis (deposit of fat in arteries of heart) and hypothyroidism, (3) Decreased cholesterol levels in serum is indicative of liver ailment and hyperthyroidism, (4) Corticosteroids (i. Theory : All colorimetric enzymatic assays essentially involve the measurement of the activity of an ezyme under the following two circumstances, namely : (a) When substrate is in large excess, and (b) When enzyme concentration is in large excess. Therefore, with a view to obtaining the best results, the two experimental parameters, namely : the temperature (constant-temperature-water-bath) and the time (phaser) should always be kept constant in order that the rate of reaction, as determined by the amount of product formed, specially designates the activity of the enzyme under assay, and devoid of the influence of any other variables on the reaction rate. Enzyme Concentration in Large Excess In order to analyze the quantity of substrate (S) present in a biological sample glucose oxidase is added in excess of the actual amount needed for the complete conversion of all the substrate to product ; and to achieve this object the reaction is allowed to run for a fairly long duration (i. Assay Methods A few typical examples of colorimetric assay of enzyme levels will be discussed briefly hereunder : 2. The resulting amount of p-nitrophenolate ion is estimated by the help of an usual standard curve employing known concentrations of p-nitrophenolate prepared from p-nitrophenol. Bessey-Lowry Activity : One unit of activity may be defined as the amount of enzyme present in 1 millilitre of serum that liberates 1µ mol of p-nitrophenol (0. Elimination of Interference due to Coloured Drugs p-Nitrophenol is colourless, whereas the phenolate ion under basic conditions is yellow in appeanace. Therefore, the elimination of interference due to coloured drugs present in the serum is accomplished effectively by first, measuring the absorbance of the serum under basic conditions, and secondly, under acidic conditions. Interference due to Bilirubin Bilirubin is eliminated by dializing the incubated p-nitrophenolate ion (at pH 10. Some typical examples are, namely : amitriptyline, chloropropamide, erythromycin, phenylbutazone, sulpha-drugs and tetracyclines. The one with water serves as a reagent blank and is always needed per set of unknowns. Now, put the two tubes for incubation for exactly 30 minutes period, (iii) Enzyme activity is arrested by adding 10. Remove them from the water-bath and mix the contents thoroughly, (iv) Read out the absorbance of the unknown tube at 410 nm against the ‘reagent blank’ tube, (v) Transfer the contents from the cuvets to the respective test-tubes and add 0. This operation removes the colour developed due top-nitrophenol, (vi) Again read out the absorbance of the serum sample against the reagent blank tube at 410 nm. This gives the colour due to the serum itself, (vii) Now, the corrected reading is achieved by subtracting the reading obtained in step (vi) from the reading in step (v). The alkaline-phosphatase activity of the serum as Bessey-Lowery units is obtained from the calibration-curve step (i). Under these experimental parameters, we have : 1 Bessey-Lowry Unit = 5 × 10–8 mol of p-Nitrophenolate anion. Thus, one unit of phosphatase activity liberated 1 µ mol of p-nitrophenol (l µ mol = 0. Note : In case, a value more than 10 Bessey-Lowry Units is obtained, it is always advisable to repeat the process either with a smaller volume of serum or a shorter incubation period, and then finally adjust the calculations accordingly. In a kinetic enzymatic assay a unit of enzyme activity is defined as ‘the quantity of enzyme that brings about a certain absorbance increase in 30 seconds or 1 minute at a fixed temperature (for instance 25 ± 0. In this particular instance lactic acid available in an excess to ensure that the increase in pyruvic acid is linear with time, i. Hence, if the temperature (experimental) is higher or lower than that used to define a unit of activity, a definite correction factor should be applied as per Table 2. Carefully record the absorbance exactly at intervals of 30 seconds for 2 to 3 minutes. In case, the absorbance happens to rise very rapidly, repeat step 3 by diluting 0. A hapten (or haptene) is a small molecule that represents the portion of an antigenic molecule or complex which determines its immunologic specificity, for instance : cortisol ; whereas an antibody is a relatively large protein that is specific for certain haptens. An antibody is generated by binding the hapten to a protein, resulting into the formation of an antigen that specifically stimulates the immune system to produce antibodies specific for the hapten. The assays that utilize protein instead of antibody are normally termed as competitive protein bind- ing assays. As an antibody is also a protein, therefore, a radioimmunoassay may be looked upon as a type of competitive protein binding assay. Theory : Generally, a radioimmunoassay makes use of a radioactive hapten and subsequently the percent of radioactivity bound to the antibody is measured. The radioactivity is determined by the help of a Geiger- Müller Counter or Geiger-Counter or G-M Tube and sometime by a Scintillation Counter. First of all, a ‘Standard Curve’ or a ‘Calibration Curve’ is plotted between the reciprocal value (i.
