SIDE EFFECTS

More than 6000 patients world-wide have received nisoldipine in clinical trials for the treatment of hypertension, either as the immediate release or the SULAR extended release formulation. Of about 1,500 patients who received SULAR in hypertension studies, about 55% were exposed for at least 2 months and about one third were exposed for over 6 months, the great majority at doses equivalent to 17 mg and above.

SULAR is generally well-tolerated. In the U.S. clinical trials of SULAR in hypertension, 10.9% of the 921 SULAR patients discontinued treatment due to adverse events compared with 2.9% of 280 placebo patients. The frequency of discontinuations due to adverse experiences was related to dose, with a 5.4% and 10.9% discontinuation rate at the lowest and highest daily dose, respectively.

The most frequently occurring adverse experiences with SULAR are those related to its vasodilator properties; these are generally mild and only occasionally lead to patient withdrawal from treatment. The table below, from U.S. placebo-controlled parallel dose response trials of SULAR using doses across the clinical dosage range in patients with hypertension, lists all of the adverse events, regardless of the causal relationship to SULAR, for which the overall incidence on SULAR was both > 1% and greater with SULAR than with placebo.

Adverse Event Nisoldipine (%)
(n=663)
Placebo (%)
(n=280)
Peripheral Edema 22 10
Headache 22 15
Dizziness 5 4
Pharyngitis 5 4
Vasodilation 4 2
Sinusitis 3 2
Palpitation 3 1
Chest Pain 2 1
Nausea 2 1
Rash 2 1

Only peripheral edema and possibly dizziness appear to be dose related.

Adverse Event (Rates in %) SULAR, dose bioequivalent to:
Placebo
N=280
8.5mg
N=30

25.5mg
N=105
34mg
N=139
Peripheral Edema 10 7 15 20 27
Dizziness 4 7 3 3 4

The common adverse events occurred at about the same rate in men as in women, and at a similar rate in patients over age 65 as in those under that age, except that headache was much less common in older patients. Except for peripheral edema and vasodilation, which were more common in whites, adverse event rates were similar in blacks and whites.

The following adverse events occurred in ≤ 1% of all patients treated for hypertension in U.S. and foreign clinical trials, or with unspecified incidence in other studies. Although a causal relationship of SULAR to these events cannot be established, they are listed to alert the physician to a possible relationship with SULAR treatment.
