Double-blind placebo-controlled clinical evaluation of oxatimide (R 35443). A novel potent anti-allergic drug in the treatment of hay fever.

The efficacy of the new anti-allergic compound oxatimide was tested in a double-blind study against a placebo during the pollen season of 1976 in 215 patients (4 1/2--69 years) with hay fever. Adult patients were instructed to take two tablets (= 20 mg) three times a day for 2 weeks, children received one tablet/10 kg of body weight daily; in addition, they were given a supply of diphenhydramine as a potential supplement. Twelve patients, six from either group, were excluded from the analysis. A significantly higher proportion of patients from the active drug group (n = 104) experienced no or only a few days of complaints, i.e. rhinitis and conjunctivitis, as well as asthma-like complaints, as compared with those of the control group (n = 99). Also, diphenhydramine consumption became significantly lower in the active drug group from the second day onwards, whereas a gradual increase and continuous need were seen in the greater part of the control group. One week of treatment appears sufficient to judge whether the individual patient benefits from the drug or not.

Effect of steroid competition and time on the uptake of (3H)corticosterone in the rat brain; an autoradiographic study.

The localization of [3H]corticosterone in the brain and pituitary of the adrenalectomized rat was studied by autoradiography. Corticosterone was concentrated preferentially by neurons in the hippocampus, septum, amygdala, and neocortex, with the hippocampal and septal neurons having the greatest concentration. [3H]-Corticosterone localization was significantly greater in neurons from adrenalectomized animals. Administration of unlabeled corticosterone (3 mg) 30 min before injection with [3H]corticosterone significantly decreased cellular localization of the labeled corticosterone, whereas [3H]corticosterone localization was not affected by progesterone pretreatment. Animals were sacrificed 15, 30 and 120 min after the injection of [3H]corticosterone to study the distribution of the hormone over the cytoplasm and nuclei. Silver grains were localized primarily over the cytoplasm of the concentrating neurons 15 min after injection; however, by 30 min after injection they were evenly distributed over both nuclei and cytoplasm.
