DESCRIPTION
Clonidine hydrochloride USP is a centrally acting alpha-agonist
hypotensive agent available as tablets
for oral administration in three dosage strengths: 0.1 mg, 0.2 mg and
0.3 mg. The 0.1 mg tablet is
equivalent to 0.087 mg of the free base.
Clonidine hydrochloride tablets contain the following inactive

microcrystalline cellulose, pregelatinized starch, and sodium starch
glycolate. The 0.1 mg also contains
D&C yellow #10 aluminum lake, and the 0.3 mg contains D&C yellow #10

Clonidine hydrochloride is an odorless, bitter, white, crystalline
substance soluble in water and
alcohol.
CLINICAL PHARMACOLOGY
Clonidine stimulates alpha-adrenoreceptors in the brain stem. This
action results in reduced sympathetic
outflow from the central nervous system and in decreases in peripheral
resistance, renal vascular
resistance, heart rate, and blood pressure. Clonidine hydrochloride
USP tablets act relatively rapidly.
The patient's blood pressure declines within 30 to 60 minutes after an
oral dose, the maximum decrease
occurring within 2 to 4 hours. Renal blood flow and glomerular
filtration rate remain essentially
unchanged. Normal postural reflexes are intact; therefore, orthostatic
symptoms are mild and infrequent.

Acute studies with clonidine hydrochloride in humans have demonstrated
a moderate reduction (15% to
20%) of cardiac output in the supine position with no change in the
peripheral resistance: at a 45° tilt
there is a smaller reduction in cardiac output and a decrease of
peripheral resistance
