Randomized Controlled Trial Comparative Study Clinical TrialPostextraction pain relief in children: a clinical trial of liquid analgesics.
Our objective was to evaluate the relative efficacies of four liquid analgesics in children, five to twelve years of age, following dental extractions. The analgesics, acetaminophen elixir (240 or 360 mg), acetaminophen with codeine elixir (240 mg and 24 mg, respectively), aluminum ibuprofen suspension (200 mg), and placebo liquid were administered at home, as a single dose, in a randomized double-blind study design. Of the 154 patients enrolled, 45 were evaluated, 39 patients never required medication, 12 were lost to follow-up, and 8 were excluded for other reasons. ⋯ The global rating of drug efficacy was statistically superior for aluminum ibuprofen. The majority of patients in all four groups were pain-free after four hours. No adverse reactions were reported during the study.

ReviewCurrent status of labetalol, the first alpha- and beta-blocking agent.
Labetalol is a unique antihypertensive agent which is a competitive peripheral antagonist at both alpha- and beta-adrenoceptor sites. Clinically, it possesses about one fourth of the beta-adrenoceptor blocking activity of propranolol and one half of the alpha-adrenoceptor blocking activity of phentolamine with a beta- to alpha-blocking ratio of approximately 7:1. Nowadays, the clinical profile of labetalol is clearly defined. ⋯ In induced hypotension during anesthesia and surgery no invasive blood pressure measurements are needed. The most frequent adverse effects include fatigue, postural hypotension, headache and gastrointestinal complaints. On the whole, labetalol expands the armamentarium of the practising physician in the treatment of hypertension of different origin.
