PRESCRIBING INFORMATION
DESCRIPTION
CATAPRES-TTS is a transdermal system providing continuous systemic
delivery of clonidine for 7
days at an approximately constant rate. Clonidine is a centrally
acting alpha-agonist hypotensive agent. It
is an imidazoline derivative with the chemical name 2,
6-dichloro-N-2-imidazolidinylidenebenzenamine
and has the following chemical structure:
CATAPRES
SYSTEM STRUCTURE AND COMPONENTS
CATAPRES-TTS transdermal therapeutic system is a multi-layered film,
0.2 mm thick, containing
clonidine as the active agent. The system areas are 3.5 cm
(CATAPRES-TTS-1), 7.0 cm
(CATAPRES-TTS-2) and 10.5 cm (CATAPRES-TTS-3) and the amount of drug
released is directly
proportional to the area (see RELEASE RATE CONCEPT). The composition
per unit area is the same for all
three doses.
Proceeding from the visible surface towards the surface attached to
the skin, there are four consecutive
layers: 1) a backing layer of pigmented polyester and aluminum film;
2) a drug reservoir of clonidine,
mineral oil, polyisobutylene, and colloidal silicon dioxide; 3) a
microporous polypropylene membrane
that controls the rate of delivery of clonidine from the system to the
skin surface; 4) an adhesive
formulation of clonidine, mineral oil, polyisobutylene, and colloidal
silicon dioxide. Prior to use, a
protective slit release liner of polyester that covers the adhesive
layer is removed.
Cross Section of the System:
RELEASE RATE CONCEPT
Catapres-TTS® (clonidine) transdermal therapeutic system is
programmed to release clonidine at an
approximately constant rate for 7 days. The energy for drug release is
derived from the concentration
gradient existing between a saturated solution of drug in the system
and the much lower concentration
