Fukui-Soubou M, Terashima H, Kawashima K, Utsunomiya O, Terada T - Drugs R D (2011)

Bottom Line: The aim of this study was to confirm the efficacy, safety, and expected palatability of amlodipine orally disintegrating tablets (ODT) [RACTAB(®) formulation (Towa, Osaka, Japan)].The results of this postmarketing surveillance study indicated that the efficacy, safety, and palatability of amlodipine ODT met our expectations (dissolves quickly in the mouth, tastes good, and is not rough on the tongue).Accordingly, amlodipine ODT are believed to be an easy-to-use formulation for prescribing doctors, dispensing pharmacists, and patients receiving treatment.

ABSTRACT

Objective: The aim of this study was to confirm the efficacy, safety, and expected palatability of amlodipine orally disintegrating tablets (ODT) [RACTAB(®) formulation (Towa, Osaka, Japan)]. We report the re-analyzed results of 1687 cases in clinical settings obtained through postmarketing surveillance in Japan.

Method: Study subjects were patients receiving treatment for the first time with amlodipine ODT for hypertension under routine care. A multicenter central registration system was used for this prospective survey. The survey was conducted from October 2008 to October 2010. The observational period was 12 weeks, during which time surveys on outpatient blood pressure, adverse events, palatability, etc. were conducted.

Results: Blood pressure stabilized following treatment, and both systolic and diastolic blood pressures were favorably controlled. Adverse events observed were not significantly different from those observed during drug use trials of amlodipine formulations reported in 2003. Moreover, palatability of amlodipine ODT showed a 99.6% (227 of 228 cases) favorable patient acceptance, which is consistent with the initial design concept of RACTAB(®) formulation.

Conclusions: The results of this postmarketing surveillance study indicated that the efficacy, safety, and palatability of amlodipine ODT met our expectations (dissolves quickly in the mouth, tastes good, and is not rough on the tongue). Accordingly, amlodipine ODT are believed to be an easy-to-use formulation for prescribing doctors, dispensing pharmacists, and patients receiving treatment.

Mentions: Regarding the palatability of amlodipine ODT, figure 5 shows the results of patient interviews conducted by the doctors involved in the survey 12 weeks after treatment initiation or termination. Of the 1355 cases in which a response was obtained on palatability, 228 patients (16.8%) recorded that the medicine was ‘mostly ingested without water’. Among them, 227 (99.6%) found the medicine ‘easy to ingest’ and one (0.4%) found it ‘difficult to ingest’. The reasons for the medicine being considered ‘easy to ingest’ included ‘dissolves quickly in the mouth’ (170 cases), ‘tastes good’ (129 cases), and ‘not rough on the tongue’ (56 cases), whereas the reason for the medicine being considered ‘difficult to ingest’ was ‘tastes bad’.
