What is Patient Information in Detail?

In actual clinical practice or in other clinical trials, these frequency estimates may not apply, as the conditions of use, reporting behavior, and the kinds of patients treated may differ. Table 3 lists treatment emergent signs and symptoms that were reported in at least 2% of patients in placebo-controlled trials who received ARICEPT and for which the rate of occurrence was greater for patients treated with ARICEPT than with placebo. In general, adverse events occurred more frequently in female patients and with advancing age. The events cited reflect experience gained under closely monitored conditions of clinical trials in a highly selected patient population.

There is evidence to suggest that the frequency of these common adverse events may be affected by the rate of titration. These patients were titrated to a dose of 10 mg/day over a 6-week period. The rates of common adverse events were lower than those seen in patients titrated to 10 mg/day over one week in the controlled clinical trials and were comparable to those seen in patients on 5 mg/day. An open-label study was conducted with 269 patients who received placebo in the 15 and 30-week studies.

The frequencies represent the proportion of 900 patients from these trials who experienced that event while receiving ARICEPT. To provide an overall estimate of the proportion of individuals having similar types of events, the events were grouped into a smaller number of standardized categories using a modified COSTART dictionary, and event frequencies were calculated across all studies. These categories are used in the listing below. No important additional adverse events were seen in studies conducted outside the United States. Events are classified by body system and listed using the following definitions: Frequent adverse events - those occurring in at least 1/100 patients; Infrequent adverse events - those occurring in 1/100 to 1/1000 patients. Treatment emergent signs and symptoms that occurred during three controlled clinical trials and two open-label trials in the United States were recorded as adverse events by the clinical investigators using terminology of their own choosing. These adverse events are not necessarily related to ARICEPT treatment and in most cases were observed at a similar frequency in placebo treated patients in the controlled studies. All adverse events occurring at least twice are included, except for those already listed in Tables 2 or 3, COSTART terms too general to be informative, or events less likely to be drug related.
