Side effects of Pendine in details

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

A total of 359 patients with neuropathic pain associated with postherpetic neuralgia have received Pendine at doses up to 1800 mg daily during placebo-controlled clinical studies. In clinical trials in patients with postherpetic neuralgia, 9.7% of the 359 patients treated with

Pendine and 6.9% of 364 patients treated with placebo discontinued prematurely due to adverse reactions. In the Pendine treatment group, the most common reason for discontinuation due to adverse reactions was dizziness. Of Pendine-treated patients who experienced adverse reactions in clinical studies, the majority of those adverse reactions were either “mild” or “moderate”.

Table 4 lists all adverse reactions, regardless of causality, occurring in at least 1% of patients with neuropathic pain associated with postherpetic neuralgia in the Pendine group for which the incidence was greater than in the placebo group.

Table 4: Treatment-Emergent Adverse Reaction Incidence in Controlled Trials in Neuropathic Pain Associated with Postherpetic Neuralgia (Events in at Least 1% of all Pendine-Treated Patients and More Frequent Than in the Placebo Group)

In addition to the adverse reactions reported in Table 4 above, the following adverse reactions with an uncertain relationship to Pendine were reported during the clinical development for the treatment of postherpetic neuralgia. Events in more than 1% of patients but equally or more frequently in the Pendine-treated patients than in the placebo group included blood pressure increase, confusional state, gastroenteritis viral, herpes zoster, hypertension, joint swelling, memory impairment, nausea, pneumonia, pyrexia, rash, seasonal allergy, and upper respiratory infection.

Postmarketing And Other Experience With Other Formulations Of Pendine

In addition to the adverse experiences reported during clinical testing of Pendine, the following adverse experiences have been reported in patients receiving other formulations of marketed Pendine. These adverse experiences have not been listed above and data are insufficient to support an estimate of their incidence or to establish causation. The listing is alphabetized: angioedema, blood glucose fluctuation, breast enlargement, elevated creatine kinase, elevated liver function tests, erythema multiforme, fever, hyponatremia, jaundice, movement disorder, Stevens-Johnson syndrome.

Adverse events following the abrupt discontinuation of Pendine immediate release have also been reported. The most frequently reported events were anxiety, insomnia, nausea, pain and sweating.
