A 65-year-old female suffering from lumbago, headache, and hypertension had been treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and antihypertensive drugs. On June 13, 1990, 2 weeks after the commencement of loxoprofen administration, she developed cough and low grade fever. She was treated with antibiotics and NSAIDs without improvement. Laboratory data showed marked eosinophilia (2200/mm3), elevation of IgE (3090 IU/ml), and liver dysfunction. Her chest X-ray revealed no active lesion, but the percentage of eosinophils in BALF was elevated (38%). Because drug-induced eosinophilic pneumonia was suspected, all drugs were discontinued. Her symptoms improved and the abnormalities of laboratory data normalized. The lymphocyte stimulation test was weakly positive with three NSAIDs (loxoprofen, pranoprofen, and alminoprofen). The challenge test by loxoprofen reproduced eosinophilia and liver dysfunction, suggesting that she had loxoprofen-induced eosinophilic pneumonia. To our knowledge, this is the first reported case of loxoprofen-induced lung injury.

The efficacy and safety of the treatment of arterial hypertension with the ACE-inhibitor quinapril, were evaluated in a multicentre study conducted in Italy. The study, lasting 14 weeks, after a preliminary wash-out period, allowed response-based titration of quinapril dose from 10 mg to 40 mg once a day, with provision to combine additional hydrochlorothiazide (12.5 to 25 mg), in case of persistently high diastolic pressure levels. The efficacy sample included 1267 patients: at therapy week 14, 78.6% of patients were treated with quinapril alone. Global response rate (intent-to-treat) was 83.3%, with a mean reduction of diastolic pressure of 15.8 mmHg (95% confidence interval from 15.5 to 16.2 mmHg). 91 patients reported 126 associated adverse events (7.0%); the most frequently reported event was cough (2.7%). First-dose hypotension was rarely reported (1.3%), even in elderly and diabetic patients.

A total of 930 patients have been evaluated for safety in a programme of clinical trials for lisinopril-hydrochlorothiazide combination treatment. Combination therapy with these two agents is generally well tolerated. In clinical trials, adverse experiences in patients treated with a lisinopril-hydrochlorothiazide combination were dizziness (7.5%), headache (5.2%), cough (3.9%), fatigue (3.7%), orthostatic effects (3.2%), diarrhoea (2.5%), nausea (2.2%) and upper respiratory tract infection (2.2%). Withdrawals from treatment have been relatively infrequent comprising dizziness (0.8%), headache (0.3%), cough (0.6%), fatigue (0.4%), diarrhoea (0.2%), orthostatic effects and nausea (0.1% each). The most common laboratory adverse experiences in patients on therapy with the lisinopril-hydrochlorothiazide combination are: increases in serum glucose, triglycerides, uric acid, serum creatinine, blood urea nitrogen and blood urea; and decreases in serum potassium. However, in individual controlled studies, the addition of lisinopril to treatment with hydrochlorothiazide results in attenuation of some of the potentially adverse metabolic affects of the diuretic. Adverse experiences in the patients treated for periods of 50 weeks or more, the elderly and the renally impaired are similar to those seen in the total population. Overall the available data indicate that a fixed dose combination of lisinopril-hydrochlorothiazide is a well-tolerated therapeutic option in patients with mild-to-moderate hypertension.

Most of the symptoms from a malignant tumor are caused by local invasion by the tumor, or obstruction, either at the site of the primary disease or by metastases. However, tumors can produce symptoms at a remote site. Patients with gastrointestinal malignancy may present with symptoms which include dysphagia, nausea, vomiting, abdominal pain, diarrhea, bleeding and ascites. Palliation gastrectomy delays or prevents these symptoms. About 30% of gastric carcinomas are inoperable at the time of presentation. Chemotherapy is rarely effective in the palliation of gastric carcinoma. Laser irradiation can be delivered to assay site accessible to fibreoptic endoscopy, which is an advantage over endocavity irradiation or diathermy fulguration. Ascites is a common and disabling implication in patients with advanced malignant disease. Spironolactone will increase urinary sodium excretion significantly and control their ascites. If spironolactone fails to control, useful control can be achieved by draining the ascites. Patients with carcinoma of the lung may present with symptoms that include cough, bloody sputum and dyspnoea. Pain in the chest wall is usually secondary to invasion of the parietal pleura, ribs or intercostal nerves. Lesions in the medial portion of the right upper lobe, or mediastinal metastases, may invade or compress the superior vena cava, causing venous hypertension with oedema of the head and arms. The patients may complain of dyspnoea, dysphagia, stridor and headaches. Radiotherapy can be expected to improve the quality of life for these patients. Successful palliation of symptoms is almost related to tumor regression. The problems of obstruction and bleeding from malignant tumor is common. Recently, laser techniques have been applied to aid in palliation of these problems. Malignant effusion may occur early and be the first signs of metastases. The aim of therapy is to evacuate the fluid and induce pleural adhesion. One of the sad situations that we have to face is the patient with recurrent cancer which complains of various symptoms. The relief of symptoms is the most important palliative therapy to them.

In this study, we compared the effects of nitrendipine (20-40 mg daily) and enalapril (20-40 mg daily) in 44 patients with mild to moderate essential hypertension. After a 4-week placebo period, the patients entered a double-blind, crossover study of 16 weeks, divided by a second 4-week placebo period. Sitting and standing blood pressures (standard mercurymeter) were measured every 2 weeks. Ten patients dropped out, so 34 patients were evaluable. Two patients dropped out because of surgery, one patient was withdrawn because of accelerating hypertension, and seven patients discontinued because of side effects (two on placebo, four on enalapril, and one on nitrendipine). Sitting blood pressures decreased from 172 +/- 3/107 +/- 1 to 159 +/- 3/94 +/- 1 mm Hg on nitrendipine (p less than 0.001) and to 157 +/- 4/96 +/- 2 mm Hg on enalapril (p less than 0.001). The heart rate did not change. Both compounds had no significant effect on serum lipids and on renal function. With regard to side effects, flushing occurred in 10 patients on nitrendipine and in 3 on enalapril (p less than 0.05); cough was noted in 3 patients on enalapril. When using a diastolic pressure less than 95 mm Hg as a response, 72% responded on nitrendipine and 64% on enalapril (n.s.). In conclusion, nitrendipine and enalapril, given as monotherapy, were equally effective antihypertensive agents in this group of patients with uncomplicated, moderate, essential hypertension. The use of either of the tested agents seems to be more limited by its specific side effects than the lack of antihypertensive efficacy.

In this study, the tolerability and safety of ramipril, as monotherapy and in combination with a low dose of furosemide, were assessed in patients with mild-to-moderate hypertension in general practice. After a placebo run-in phase, patients received ramipril as monotherapy in a dose of 2.5 to 5 mg daily for 6 weeks. Nonresponders (diastolic blood pressure greater than 90 mm Hg) entered a double-blind treatment period, and received either 10 mg of ramipril daily, or 5 mg of ramipril in combination with 20 mg of furosemide daily. The tolerability of the study medication was assessed by reported adverse events, and by monitoring blood cell count, electrolytes, serum creatinine, fasting blood glucose, and apolipoproteins AI and B. Of a total of 770 patients who entered the placebo run-in phase, 661 patients were enrolled in the first active treatment period. The most commonly reported adverse events were headache, cough, dizziness, asthenia, cramps, diarrhea, and nausea, but not all of these events were related to ramipril treatment. A total of 38 patients discontinued active treatment due to nonserious adverse events, mainly cough, dizziness, or diarrhea. There appeared to be a relationship between the prevalence of cough and ramipril dosage; however, an increased incidence of cough was also observed during outbreaks of influenza in France. There were no significant changes in laboratory variables during the study.

Cardiac hypertensive structural changes, catecholamine-related cardiomyopathy, and congestive heart failure (CHF) have been encountered in pheochromocytoma, as a result of prolonged exposure to high concentrations of endogenous catecholamines. A 34-year-old man presented with severe hypertension, cardiomegaly, and CHF, presumably as a result of continuous alpha-adrenergic intoxication with oxymetazoline hydrochloride, phenylephrine hydrochloride, and ephedrine hydrochloride, consumed in massive doses by an overuse of nasal decongestants and cough syrup (daily doses of 20, 100, and 300 mg, respectively). Coadministered chlorpromazine hydrochloride and trimeprazine tartrate may have also contributed to the clinical presentation through their anticholinergic and antihistaminic properties. The possibility of an overuse of these over-the-counter drugs should be considered in the differential diagnosis of hypertensive emergencies, especially with the simultaneous use of anticholinergic and antihistamine medications, beta-blocking agents, or monoamine oxidase inhibitors.

This article examines the evidence justifying the use of angiotensin-converting enzyme (ACE) inhibitors as first-line antihypertensive drugs. ACE inhibitors are as effective as traditional antihypertensive agents and, in addition, exert their blood-pressure-lowering effect with near optimal hemodynamic alterations. These drugs have a good tolerance and safety profile although they induce cough in an appreciable number of patients. They can be safely associated with other antihypertensive agents to provide therapeutic benefit in a large proportion of the hypertensive population. ACE inhibitors are contraindicated only in bilateral renal artery stenosis or stenosis of a single kidney. Although to date no prospective study has examined the ability of ACE inhibitors to reduce cardiovascular morbidity and mortality in hypertension, several features of these drugs suggest that this may be the case as several effects of ACE inhibitors in hypertension are potentially nephroprotective and cardioprotective.

Captopril is widely used for congestive heart failure and arterial hypertension. Its main side effects are cough, neutropenia, and renal injury. Liver dysfunction has rarely been described. We present a 71-year-old man with an acute myocardial infarction who developed high fever and progressive disturbance of liver function tests, hepatocellular and cholestatic, after beginning captopril. When other, more likely causes for his condition were ruled out, captopril was discontinued and the fever and liver dysfunction then quickly resolved. We recommend periodic laboratory follow-up in patients treated with angiotensin-converting enzyme inhibitors.

The failure of up to half of all patients in developing countries to adhere to recommended drug regimens may reflect inadequate physician- provider communication rather than resistance to treatment. There is substantial evidence that patients are more likely to conform to treatment regimens when they are fully informed about their medical condition and the medication prescribed. To investigate the extent to which patients in Zimbabwe received this type of information, household heads in 910 households in the Mashonaland West Province were interviewed. The sample included equal numbers of respondents from urban, rural, and commercial farming areas. Diseases most commonly reported by rural residents and farmers were diarrhea, influenza, cough, hypertension, and malaria. Most of the illnesses were attributed to natural or supernatural causes, and 80% of respondents in these subsamples claimed to distrust their health care provider and never asked questions about medications prescribed. The rural residents perceived health care personnel as too busy to answer questions and did not believe they would understand any information offered. On the other hand, these respondents indicated they would like to have information on the cause of their illness, its duration and treatment, the best way to take prescribed drugs, actions to take when drugs produce side effects, and storage of medication. Physicians who treat semi-literate rural residents with indigenous health beliefs are urged to provide information about medication tailored to match the individual perceptions and needs of the patient. This need is less urgent in urban areas, where 60% of respondents had general knowledge about the action of various medicines and were able to obtain information from pharmacists.
