Blood pressure and clinical status of 1,736 patients with cerebrovascular disease were observed during 12 months of treatment with nicardipine. The most common diagnoses were chronic cerebral ischemia (53.2%), transient ischemic attacks (TIA; 25.1%), and cerebral infarct (8.7%); 50.1% of patients were classed as hypertensive [systolic blood pressure (SBP) > or = 160 mm Hg or diastolic blood pressure (DBP) > or = 90 mm Hg]. Most patients (91.2%) received a daily dose of 60 mg nicardipine. Additional treatments included diuretics (37%), beta-blockers (11.5%), other antihypertensive drugs (15.8%), platelet antiaggregants (25.1%), and cardiotonic drugs (15.1%). A total of 282 patients (16.2%) were lost to follow-up, 21 (1.2%) patients withdrew due to side effects, 32 (1.8%) died, and 9 (0.5%) patients had treatment interrupted due to concomitant illness. In the hypertensive subgroup, blood pressure (SBP/DBP) was reduced from a mean baseline value of 175 +/- 22/97 +/- 14 mm Hg to 152 +/- 17/85 +/- 11 mm Hg at 3 months and 149 +/- 23/81 +/- 11 mm Hg after 12 months of treatment. The incidence of TIA or stroke among these patients was reduced from 29 cases (3.5%) during the first 3 months to 11 cases (1.54%) during months 4-12 (p < 0.01). In normotensive patients there were 18 (2.15%) cases during months 1-3 and 13 (1.55%) cases during months 4-12 (difference not significant). In the 280 patients treated with nicardipine alone, the most frequent side effects during the first month were facial flushing (6.8%), gastrointestinal problems (5%), dizziness (3.2%), headache (3.2%), drowsiness (3.2%), and hypotension (1.1%). Most of these side effects were transient.(ABSTRACT TRUNCATED AT 250 WORDS)

A cutaneous test has been applied in examination of the flushing response to ethanol and acetaldehyde in 402 Chinese of Han ethnicity. Using this noninvasive method, five response subtypes have been observed: (A) fast flushing to both ethanol and acetaldehyde; (B) fast flushing only to ethanol but not to acetaldehyde; (C) slow flushing to ethanol only; (D) no response either to ethanol or to acetaldehyde; (E) vasoconstriction to ethanol, or to both ethanol and acetaldehyde. A total of 94% in subtype (A) are reported to be flushers, while only 25% was reported in subtype (D). Other physiological responses, such as tachycardia, dizziness, headache, drowsiness, and nausea are less frequent after alcohol ingestion. The recent history of consumption of alcohol of the subjects in different subtypes was also obtained. Although alcohol-induced flushing is thought to be a deterrent factor to heavy consumption of alcohol, the frequency of drinking of alcoholic beverages was not found to be different between flushers and nonflushers.

In an earlier project, we identified five alcohol-consumption aftereffect factors, which were named Hangover, Euphoria, Flushing, Seizures, and Sleepiness. In this study (N = 100) we assessed the construct validities of the five, using 47 MMPI, self-report, and recidivism criteria. The number of significant relationships between the factors and the criteria substantially exceeded chance. The Hangover factor related to social maladjustment and to the MMPI Psychopathic Deviate, Paranoia, Psychasthenia, Hypomania, and Masculinity-Femininity scales. The Euphoria factor was associated with a high number of job losses, but a low incidence of certain physical sequelae. The Flushing factor was associated with high consumption, late development of alcoholism, many physical complaints, and older age. The Seizure factor correlated with high consumption, facial puffiness, tremors, and lack of defensiveness on the MMPI. The Sleepiness factor was associated with a good prognosis and several mild MMPI elevations. These findings suggest that the factors may provide the basis for a useful alcoholism subtyping system and that additional research on them should prove fruitful.

A double-blind controlled, randomized, parallel, multicenter 12-week study was conducted to compare the antihypertensive efficacy of lisinopril with that of metoprolol in treatment of moderate to severe hypertension. Initially, 118 patients were recruited on lisinopril and 61 on metoprolol; and for the purpose of efficacy analysis at week 8, 115 patients on lisinopril and 60 on metoprolol were included. The doses of lisinopril or metoprolol were 40-80 mg/day and 100-200 mg/day, respectively. At week 4, the pretreatment diastolic blood pressure of 111 mm Hg was decreased to 97 mm Hg (p less than 0.01) with lisinopril: metoprolol decreased the diastolic blood pressure from 110 to 99 mm Hg (p less than 0.01). Similar decreases were noted at week 8; however, the drop in blood pressure with lisinopril was not significantly different from that with metoprolol. Systolic blood pressure also demonstrated a decrease of about 18 mm Hg with lisinopril and 12 mm Hg with metoprolol (p less than 0.01). This larger decrease in systolic blood pressure with lisinopril was statistically significant at week 4 (p less than 0.05). These decreases in systolic blood pressures were maintained at week 8, again with statistical significance (p less than 0.01). Of the 118 lisinopril-treated patients, four were discontinued from lisinopril therapy because of headache, dizziness, rash, flushing, or lymphadenopathy. Four patients out of 61 (9.8%) were discontinued from metoprolol therapy because of fatigue, somnolence, asthenia, weight gain, flatulence, tremor, or bronchospasm. In conclusion, lisinopril 40-80 mg once daily is as effective as metoprolol 100-200 mg once daily in reducing diastolic blood pressure in patients with moderate to severe hypertension.(ABSTRACT TRUNCATED AT 250 WORDS)

The so-called Oriental flushing reaction associated with ingestion of small amounts of alcohol was antagonized by combined antihistamine administration. In stage one of the study, the flushing reaction to low doses of alcohol was produced in Orientals. Most subjects experienced a cutaneous flush, increase in skin temperature, decrease in blood pressure, increase in pulse rate and subjective symptoms such as dizziness, sleepiness, anxiety, headache, generalized weakness and nausea. One half of the group of subjects was then given diphenhydramine, 50 mg (H1 receptor antagonist) and cimetidine, 300 mg (H2 receptor antagonist) and the second half received placebo tablets before the administration of alcohol. The clearest difference between the antihistamine group and placebo group was in the skin flushing reaction. The antihistamine group showed a statistically significant reduction in the skin flush. The antihistamines also neutralized the systolic hypotension induced by the administration of alcohol.

Epoprostenol (Prostacyclin) has been studied with various success in patients with peripheral vascular disease (PVD). We investigated the tolerance of a new, stable prostacyclin derivative ciprostene (9-beta-methyl carbacyclin) in 9 PVD patients. The drug was infused intravenously for 8 hours a day, once a week for 4 consecutive weeks, at a dose of 120 ng/kg/min. There were 6 men and 3 women with a mean age of 63 years (42-78). The PVD was verified by arteriography (9 patients) and by clinical findings. Patient #9 was lost to follow up after the first infusion and, consequently, was excluded from further evaluation. In patient #5 with a history of arrhythmias, the last ciprostene infusion had to be discontinued at 4.5 hours due to arrhythmias but his data were included into the evaluation. The cardiac disturbances were not judged to be ciprostene-related. Patients were followed monthly for 3 months after last infusion. Ciprostene was well tolerated although it produced adverse medical events (AMEs); most of them were rated as mild. The most frequent were those typical of prostacyclin: headache, facial flushing and warmth, body warmth, jaw pain and sleepiness. No consistent changes in blood pressure and heart rate were observed. One patient who initially had 9 ischemic ulcers underwent transmetatarsal amputation at month 4. The absolute and relative claudication time was measured by treadmill. As compared to baseline, the absolute claudication time increased significantly at week 2 and 4 of the infusion period and also at the end of month 3, but not at the end of month 4.(ABSTRACT TRUNCATED AT 250 WORDS)

The so-called Oriental flushing reaction associated with ingestion of small amounts of alcohol was antagonized by combined antihistamine administration. In stage one of the study, the flushing reaction to low doses of alcohol was produced in Orientals. Most subjects experienced a cutaneous flush, an increase in skin temperature, a decrease in blood pressure, an increase in pulse rate and subjective symptoms such as dizziness, sleepiness, anxiety, headache, generalized weakness and nausea. Before the administration of alcohol, one-half of the subjects were given 50 mg of diphenhydramine (H1 receptor antagonist) and 300 mg of cimetidine (H2 receptor antagonist). The second half received placebo tablets. The clearest difference between the antihistamine group and placebo group was in the skin flushing reaction. The antihistamine group showed a significant reduction in the skin flush. The antihistamine also neutralized the systolic hypotension induced by the administration of alcohol. The possible importance of histamine in the expression of sensitivity to alcohol is considered. The relevance to genetic susceptibility for development of alcoholism is discussed.

Aspirin (ASA) was tested in a group of 8 Oriental and 3 Occidental subjects who were shown in a previous study to respond to small doses of ethanol (0.06-0.25 g/kg) with facial flushing. They were compared to a similar group of 11 non-flushing Occidental subjects following a larger ethanol dose (0.37 g/kg) to determine if similar effects could be produced in less sensitive individuals. Control tests of blood ethanol and acetaldehyde (AcH) levels (calculated from breath), facial and neck skin temperatures, body sway (Romberg test), blood pressure, heart rate and 10 Subjective High Assessment Scales (SHAS-Judd, 1977) were conducted before and at 15, 30, 60 and 90 minutes after drinking ethanol as vodka in orange juice. The tests were repeated one week later one hour after receiving 0.64 gm of ASA orally. ASA produced slight changes in the early absorption of ethanol and small decreases in AcH levels in the flushing and non-flushing groups. Facial flushing was markedly reduced in the flushing group, but was slightly increased in the non-flushing Occidentals. Body sway was reduced by ASA in both groups. An alcohol-induced increase in heart rate in the flushing group was reduced with no change in blood pressure. SHAS subjective parameters were widely variable, but indicated that ASA produced reduced sleepiness and earlier relaxation in the flushing group. It is concluded that ASA can block alcohol-induced facial flushing in sensitive subjects and also reduces body sway in the Romberg test and alters some subjective feelings of alcohol intoxication.

In 93 patients with hypertension uncontrolled by bendrofluazide 5 mg plus atenolol 100 mg daily, the effects of adding nifedipine (up to 60 mg/day, n = 31), prazosin (up to 20 mg/day, n = 31), or hydralazine (up to 200 mg/day, n = 31) were compared in a 6 month open random parallel group study. The three drugs did not differ significantly as regards antihypertensive effect, withdrawal rate, total number of side effects, or effect on serum biochemical variables. The pattern of side-effects differed. Headache, flushing and oedema were common with nifedipine, tiredness and drowsiness with prazosin, and headache with hydralazine. Nifedipine is an acceptable third-line antihypertensive drug which may have some advantage over hydralazine and prazosin.

The Oriental flushing reaction is an adverse response to alcohol that appears to be genetically determined. In this study, the Oriental flushing reaction that was produced with ingestion of small amounts of alcohol was antagonized by antihistamine administration. A group of 17 subjects was tested. Each subject received placebo, diphenhydramine 50 mg (H-1 receptor antagonist), and cimetidine 300 mg (H-2 receptor antagonist) singularly and in combination. Alcohol was then administered orally. Most subjects given placebo experienced the typical flushing reaction that included a cutaneous flush, increase in skin temperature, decrease in blood pressure, increase in pulse rate and subjective symptoms such as dizziness, sleepiness, anxiety, headache, generalized weakness, and nausea. The flush, temperature and systolic hypotension were significantly blocked by the combined antihistamine administration. Cimetidine given alone blocked the flush, temperature increase, and systolic hypotension significantly more than diphenhydramine but less than the combined antihistamines. Diphenhydramine was similar to placebo in its effect on the flushing reaction. The role of histamine in the expression of tolerance to alcohol is not known. Antihistamine antagonism of the adverse flushing reaction suggests that histamine receptors may participate in the intolerance to ethanol in Orientals. Histamine may be an important protective factor in the low prevalence of alcoholism in Orientals.
