Letter: Cross-sensitivity between practolol and other beta-blockers?

Antinuclear antibodies in patients receiving non-practolol beta-blockers.

Antinuclear antibodies (ANA) were found in 54 (7.0%) out of 767 treated hypertensive patients compared with 59 (2.4%) out of 2470 healthy controls. Inclusion of a non-practolol beta-blocker in the treatment regimen did not significantly affect the incidence of ANA. ANA was found in significantly more patients being treated with methyldopa (13.0%) than patients receiving other hypotensive agents...

Beta blockers and the sensitivity of the thallium treadmill test.

The effect beta blockers (BB) may have on the sensitivity of the thallium treadmill test (Th-TMT) is controversial. The purpose of this study was to test the hypothesis that BB decrease the sensitivity of the Th-TMT. Two hundred three patients over a two-year period were identified who satisfied the following criteria. All had symptom-limited upright treadmill exercise tests with stress and red...

penicillin allergy and cross-reactivity with other beta-lactams.

beta-lactams are a group of antibiotics with a broad spectrum of both gram-negative and gram-positive coverage. the goal of this study is to evaluate the results from studies regarding ig-e mediated hypersensitivity to penicillin and cross-reactivity with other beta-lactams. review was conducted of both retrospective and prospective studies by searching in pubmed and medline for the original an...

Beta-blockers.

Beta-blockers and asthma.

In a single-blind, randomised, crossover study in 10 asthmatic patients, the effects of approximately equipotent oral doses of 3 cardioselective beta-blockers-atenolol (100 mg), metoprolol (100 mg), and acebutolol (300 mg)-and 4 non-cardioselective beta-blockers-proranolol (100 mg), oxprenolol (100 mg), pindolol (5 mg), and timolol (10 mg) upon FEV1 were compared. All drugs, except pindolol, pr...
