The present study investigated the effect of the new ACE-inhibitor moexipril versus the beta 1-adrenergic blocker atenolol on metabolic parameters, adverse events (AEs) and sitting systolic (SSBP) and sitting diastolic blood pressure (SDBP) in obese postmenopausal women with hypertension (stage I and II). After a 4-week placebo run-in phase, 116 obese, postmenopausal women with primary hypertension were randomised into two treatment groups receiving once daily dosages of either moexipril 7.5 mg or atenolol 25 mg initially (mean age: 57 +/- 7 years in both groups; mean weight: 94 kg in the moexipril group and 89 kg in the atenolol group, corresponding to a body mass index (BMI) of 35.2 kg/m2 and 34.1 kg/m2 in both groups, respectively). After 4 and 8 weeks, the dosages were uptitrated to moexipril 15 mg, or if necessary to moexipril 15 mg/hydrochlorothiazide (HCTZ) 25 mg, or to atenolol 50 mg and atenolol 50 mg/HCTZ 25 mg, in patients whose blood pressure was not sufficiently controlled. At endpoint, metabolic parameters (total cholesterol, triglycerides, LDL, HDL, glucose, insulin) were not significantly altered in either treatment group. Most frequent adverse events under monotherapy (moexipril/atenolol) were asthenia (5.3/13.0%), headache (13.2/21.7%), cough (7.9/6.5%), pharyngitis (21.1/8.7%) and peripheral oedema (5.3/13.0%). Overall at least one AE was reported in 66% of the patients treated with moexipril and in 78% of those treated with atenolol. Reduction of SSBP/SDBP at endpoint was 14.7 +/- 1.9/10.0 +/- 1.1 and 8.7 +/- 1.9/8.4 +/- 1.1 mmHg after treatment with moexipril and atenolol, respectively. The results showed that moexipril and atenolol are equally effective in reducing blood pressure without adversely affecting blood lipids and carbohydrate metabolism.

The TEAM trial investigated the effectiveness and tolerance of a fixed combination of the ACE inhibitor and calcium channel blocker (2 mg trandolapril and 180 mg verapamil retard) (preparation Tarka) in an open multicentre prospective study of treatment of moderately severe hypertension (diastolic pressure at the end of the two-week wash-out period 100-115 mm Hg). The trial comprised 163 patients who were treated first for four weeks by a monotherapy with 2 mg trandolapril. After these four weeks patients who attained normal blood pressure proceeded with trandolapril treatment. Hypertensive patients who did not attain normal diastolic pressure levels were treated for another four weeks by a fixed combination of trandolapril and verapamil SR. After four weeks of treatment with trandolapril 62 patients of 163 (37%) had a diastolic blood pressure of less than 90 mm Hg. The fixed combination of trandolapril and verapamil SR reduced the diastolic blood pressure to less than 90 mm Hg in 71.6% of the patients resistant to treatment with 2 mg trandolapril and in another 15.6% of patients it reduced the diastolic blood pressure by 10 mm Hg or more. After two months of treatment 60 patients had a normal blood pressure due to trandolapril (37%) and another 73 patients (45%) treated by a combination of trandolapril and verapamil SR, i.e. a total of 133 patients (82%) who originally suffered from moderately severe hypertension, attained a normal diastolic blood pressure. The mean decrease of diastolic pressure after two months of treatment was 19.5 mm Hg in "non-respondents" to trandolapril monotherapy and 23.6 mm Hg in "respondents". The mean decrease of systolic pressure in "non-respondents" and "respondents" after trandolapril treatment was 19.5 mm Hg and 35.0 mm Hg resp. The fixed combination of trandolapril and verapamil was not only effective but was associated with a minimum of undesirable effects. The incidence of headaches declined significantly. The combination of the above preparations is useful also because both preparations have a cardio- and nephroprotective effect and do not affect the lipid and carbohydrate metabolism. Treatment with a fixed combination of trandolapril and verapamil SR is indicated in moderately severe hypertension not responding to monotherapy, in particular when associated with diabetes, hyperlipoproteinaemia, ischaemic heart disease or left ventricular hypertrophy.

Co-administration of antihypertensive drug therapy and hormonal replacement therapy (HRT) is frequent in postmenopausal women but it is not known whether HRT interacts with concomitant antihypertensive therapy. The present study was designed to investigate efficacy and safety of the ACE inhibitor moexipril in comparison to placebo in hypertensive, postmenopausal women on HRT. After a 4-week placebo run-in phase, 95 postmenopausal women (35-74 years of age) who had a sitting diastolic blood pressure (BP) of 95-114 mm Hg and were treated with HRT were randomised to a 12-week treatment with moexipril 15 mg or placebo. Efficacy and safety were assessed by measuring changes in sitting BP and metabolic parameters associated with cardiovascular disease including triglycerides, total cholesterol, HDL, LDL, total cholesterol/HDL ratio and glucose. Adverse events were recorded continuously. After 12 weeks of treatment, moexipril 15 mg was significantly more effective in reducing sitting systolic and diastolic BP from baseline than placebo (-12.2/-9.9 mm Hg vs -1.6/-4.3 mm Hg, P < 0.001). Metabolic parameters were not affected by treatment with moexipril: mean levels of triglycerides, total cholesterol, HDL, LDL, total cholesterol/HDL ratio and glucose remained unchanged throughout the study. Fibrinogen, an independent cardiovascular risk factor, increased after placebo (+35.0 mg/dl) and decreased after treatment with moexipril (-33.6 mg/dl), the difference, however, was not statistically significant. Moexipril was well-tolerated by postmenopausal women using HRT. The most frequent adverse events included headache (21.3%), cough (12.8%) and rhinitis (10.6%) and there were no significant differences in the number and severity of adverse events between the moexipril and placebo groups. This study indicates that moexipril is effective and well tolerated in the treatment of hypertensive, postmenopausal women and can safely be co-administered to HRT.

A general health survey was conducted in nonpregnant and noncontracepting women aged 15-44 years to determine the presence of any health problems that might affect the use of depot-medroxyprogesterone acetate (DMPA) as a contraceptive method in rural district in Nepal. The survey included a general assessment interview by nonphysicians, followed by formal medical histories and physical exams by female gynecologists. Findings revealed that a possible pregnancy (9 cases) and abnormal uterine bleeding (1 case) were the only conditions identified in which DMPA should not be used based on the WHO Medical Eligibility Criteria for Contraceptive Use. 5 additional cases of cardiovascular problems, in which DMPA initiation was not usually recommended, were also detected. The reports included heart disease (2 cases), past history of hypertension (1 case), current hypertension (1 case), and headache and hypertension (1 case).

Complaints about unpleasant environmental odorants, both outdoor and indoor, are increasingly being reported. The main complaints of health symptoms from environmental odorants are eye, nose and throat irritation, headache and drowsiness. Complaints may arise from the stimulation of olfactory receptors or trigeminal chemoreceptors. Stimulation of cerebrovascular nociceptors originating from a branch of the trigeminal nerve may be associated with an increase in cortical blood flow which is thought to be related to headache. Since odorants are reported to elicit headaches, the possibility that odorants may increase cortical blood flow was examined. Cortical blood flow was monitored in rats using a laser-Doppler flowmeter. The flowmeter probe was placed over the left frontal cortex while propionic acid, cyclohexanone, amyl acetate or butanol was delivered to the nasal cavity via an olfactometer. Cortical blood flow increased as the concentration increased for three of the odorants tested. The greatest increase in blood flow occurred to the presentation of propionic acid, followed by cyclohexanone and amyl acetate. There was no response to butanol. These data demonstrate that odorants can alter cerebrovascular blood flow, which may account, in part, for one of the health symptoms reported for odorants.

We report our experience with the incidence of adverse events during the use of Stimate brand intranasal desmopressin acetate (IN DDAVP) for patients with haemophilia A (HA) or von Willebrand disease (vWD) after noting two severe adverse events in one adult patient. All patients with documented vWD (type 1 or 2 A) or haemophilia A (mild, moderate or symptomatic carrier) from the Emory Comprehensive Hemophilia Center who had IN DDAVP challenge testing or were using Stimate for treatment of bleeding were evaluated for adverse events by patient report or nursing observation of clinical signs and symptoms. Forty patients were studied. Sixty-eight per cent (27/40) experienced clinical signs and/or symptoms. The majority of these symptoms were mild, however several patients reported moderate to severe side-effects and one adult patient required medical intervention for symptomatic hyponatraemia. In our experience, two-thirds of patients tested experienced adverse signs and/or symptoms with the use of Stimate; considerably higher than that reported from preliminary results in the literature. Young age did not correlate positively with adverse reactions. Severe adverse events requiring medical intervention were rare, however symptoms such as moderate to severe headache, nausea, vomiting and weakness may necessitate evaluation for hyponatraemia. This is the first report of symptomatic hyponatraemia in an adult patient with recommended dosing of Stimate. Side-effects may be minimized if patients adhere to instructions regarding fluid intake and composition while using IN DDAVP.

Angiotensin II receptor blockers (ARBs) represent a new class of effective and well tolerated orally active antihypertensive agents. Recent clinical trials have shown the added benefits of ARBs in hypertensive patients (reduction in left ventricular hypertrophy, improvement in diastolic function, decrease in ventricular arrhythmias, reduction in microalbuminuria, and improvement in renal function), and cardioprotective effect in patients with heart failure. Several large long-term studies are in progress to assess the beneficial effects of ARBs on cardiac hypertrophy, renal function, and cardiovascular and cerebrovascular morbidity and mortality in hypertensive patients with or without diabetes mellitus, and the value of these drugs in patients with heart disease and diabetic nephropathy. The ARBs specifically block the interaction of angiotensin II at the AT1 receptor, thereby relaxing smooth muscle, increasing salt and water excretion, reducing plasma volume, and decreasing cellular hypertrophy. These agents exert their blood pressure-lowering effect mainly by reducing peripheral vascular resistance usually without a rise in heart rate. Most of the commercially available ARBs control blood pressure for 24 h after once daily dosing. Sustained efficacy of blood pressure control, without any evidence of tachyphylaxis, has been demonstrated after long-term administration (3 years) of some of the ARBs. The efficacy of ARBs is similar to that of thiazide diuretics, beta-blockers, angiotensin-converting enzyme inhibitors or calcium channel blockers in patients with similar degree of hypertension. Higher daily doses, dietary salt restriction, and concomitant diuretic or ACE inhibitor administration amplify the antihypertensive effect of ARBs. The ARBs have a low incidence of adverse effects (headache, upper respiratory infection, back pain, muscle cramps, fatigue and dizziness), even in the elderly patients. After the approval of losartan, five other ARBs (candesartan cilexetil, eprosartan, irbesartan, telmisartan, and valsartan) and three combinations with hydrochlorothiazide (irbesartan, losartan and valsartan) have been approved as antihypertensive agents, and some 28 compounds are in various stages of development. The ARBs are non-peptide compounds with varied structures; some (candesartan, losartan, irbesartan, and valsartan) have a common tetrazolo-biphenyl structure. Except for irbesartan, all active ARBs have a carboxylic acid group. Candesartan cilexetil is a prodrug, while losartan has a metabolite (EXP3174) which is more active than the parent drug. No other metabolites of ARBs contribute significantly to the antihypertensive effect. The variation in the molecular structure of the ARBs results in differences in the binding affinity to the receptor and pharmacokinetic profiles. The differences observed in lipid solubility, absorption/distribution, plasma protein binding, bioavailability, biotransformation, plasma half-life, and systemic elimination influence the time of onset, duration of action, and efficacy of the ARBs. On the basis of the daily mg dose, the antihypertensive potency of the ARBs follows the sequence: candesartan cilexetil > telmisartan approximately = losartan > irbesartan approximately = valsartan > eprosartan. After oral administration, the ARBs are rapidly absorbed (time for peak plasma levels = 0.5-4 h) but they have a wide range of bioavailability (from a low of 13% for eprosartan to a high of 60-80% for irbesartan); food does not influence the bioavailability, except for valsartan (a reduction of 40-50%) and eprosartan (increase). A limited dose-peak plasma levels/areas under the plasma level-time curve proportionality is observed for some of the ARBs. Most of these drugs have high plasma protein binding (95-100%); irbesartan has the lowest binding among the group (90%). The steady-state volumes of distribution vary from a low of 9 L (candesartan) to a high of 500 L (telmisartan). (ABSTRACT TRUNCATE

It has been suggested that cyproterone acetate (CPA) has a mutagenic potency. It has been postulated that a threshold dosage of CPA has mutagenic effects, but in the same way data have been published documenting that a continuous low dosage of cyproterone acetate leads to a reduction of mutagenic episodes. Despite published data about higher levels of DNA adduct creations due to CPA an international multicentre study analysing 2,506 patients with 7,971 patient-years that used CPA could not find any liver cell cancers, even if due to epidemiological data 6 liver cell cancers should have occurred upon this study group. The present study deals with the evaluation of 57 women which received CPA in combination with EE2 11-13 years before. The daily dosage was 2 mg CPA in combination with 35 mg or 50 mg EE2. In Germany these drugs were registered under the name of Diane 35 or Diane 50. Long-term follow-up evaluation concerning side effects, especially the appearance of liver cell carcinomas, were the aim of this study. With the records of 32% (18/57) of the above mentioned patient group the following long-term follow-up side effects could be observed: 1) weight gain, 2) headache, 3) migraine, 4) gastrointestinal disorders, 5) mood affections/depressions, 6) oedema of the legs, 7) skin affections, 8) mastodynia. No benign liver tumor or liver cell carcinoma was detected upon our group of investigated patients. In conclusion we can affirm that the use of CPA in a dosage of 2 mg per day does not lead to serious side effects under long-term follow-up observation conditions and that it's use does not correlate with a higher appearance of liver cell carcinomas.

In September 1996, seven patients at Hospital A suffered conjunctivitis, hearing loss, diminished vision, and headaches 7-24 h after hemodialysis treatment. Eleven-year-old dialysis modules were identified as a common link between these patients. Degradation of the cellulose acetate (CA) material was identified as the cause of this incident. Degradation products were characterized from retrieved CA dialysis membranes. A series of synthesized CA degradation products was tested in vitro to assess toxicity. Based on the toxicity of the material preparations to the cells, animal tests were performed on selected CA degradation extracts and compared to extracts from actual dialysis membranes. Rabbits were IV-injected with extracts from a 13-year-old dialyzer, synthesized model compounds, and compared to controls. Ophthamological evaluation of the rabbits showed eye injury (iritis/ciliary flush) when the animals were treated with the old dialyzer or synthesized model compounds. Isolation and characterization of a toxic fraction from both of these extracts strongly indicated that oxidative stress at some point in the storage or manufacture of CA dialyzers created degradation products that reproduced some of the patient symptoms identified at Hospital A.

The authors present the results of clinical trail about treatment of arterial hypertension with ENAP (Enalapril) fo KRKA in centers of Bulgaria. Enalapril is ACE-inhibitor usually administered orally once daily, decreases blood pressure by lowering peripheral vascular resistance without increasing heart rate or output. In this clinical trail are given results about blood pressure, heart rate and biochemical indexes. The most frequent adverse events--headache, dizziness, orthostatic effects, abdominal pain e.t.s. occurring in less than 10%. More important side effects like dry persistent cough occurring in 8.6%. The results of clinical trail define high efficacy and good tolerability of ENAP in the treatment of arterial hypertension.
