One hundred and seven adult outpatients with Leriche stage II peripheral occlusive arterial disease took part in this open, controlled trial. Patients were randomly treated over a six-month period either with sulodexide capsules containing 250 lipoproteinlipase releasing units (LRU, two capsules twice daily for 176 days on average: 56 patients), or with pentoxifylline 400 mg tablets (one tablet three times a day for 180 days on average: 51 patients). The incidences of diabetes, hyperlipoproteinaemias, smoking habit and other risk factors were the same in the two groups. The drugs' efficacies were evaluated by monitoring, at the start of treatment and every month during it, the Winsor Index and the walking distance, both prior to (initial claudication distance-IDC) and after (absolute claudication distance-ACD) the symptom's onset. Compliance with treatment and occurrence of adverse events were constantly monitored; systemic tolerability was evaluated through the use of routine haematological and haematochemical tests. Both treatments brought about a progressive increase in the claudication-free walking distance, statistically significant versus baseline from the second month (ACD, sulodexide group) and third month (ACD and ICD, pentoxifilline and sulodexide groups). At the end of treatment, the absolute increase of ACD was significantly greater in sulodexide-treated patients (p < 0.01) with respect to the pentoxifylline-treated group. In both groups the Doppler test evidenced a good improvement in local arterial haemodynamics. In the sulodexide group, 3.6% of patients developed nausea, dyspepsia and other minor gastrointestinal phenomena. In the pentoxifylline group 17.6% of patients complained of gastroenteric disorders (nausea, vomiting, dyspepsia), or of headache and dizziness. In one patient of this latter group insomnia was also present. Systemic tolerance of both drugs was consistently good.

Pharmacotherapy is limited for the relief of intermittent claudication (IC), a common manifestation of peripheral arterial disease (PAD). Pentoxyfylline, the only current pharmacological therapy for IC, has been shown to have similar efficacy as placebo. Cilostazol, a new phosphodiesterase III (PDE III) inhibitor, is a potent inhibitor of platelet aggregation with vasodilatory, antithrombotic, antiproliferative and positive lipid-altering effects. To evaluate the efficacy and safety of cilostazol for the treatment of IC in Indian patients, 123 patients were selected from 6 centres in India. The patients, aged 58-73 years, with the diagnosis of stable moderate-to-severe IC received cilostazol 100/50 mg twice daily for a period of 12 weeks. Primary efficacy measures included initial claudication distance (ICD) and absolute walking distance (ACD) by treadmill testing and ankle-brachial index (ABI) using Doppler ultrasonography-measured systolic pressures. Secondary efficacy outcomes included subjective assessment of symptom improvement by patient and investigator and estimation of lipid values. Adverse events were monitored throughout the study. Laboratory investigations were carried out at baseline and end of study. At the end of week 12 of cilostazol therapy, there was a significant improvement in the raw walking distances (ICD and ACD). Percentage change in ICD and ACD was 46.77% and 64.5%, respectively, at the end of study. There was a significant increase (32.7%) in the ABI by the end of study period. According to patient and investigator assessment of symptoms, 58-60% of the subjects showed significant improvement to complete resolution of claudication symptoms by the end of 12 weeks of therapy. In addition, there was a significant increase of 20.24% in the mean plasma HDL-cholesterol levels and a decrease of 29.55% in the mean plasma triglyceride concentrations by the end of study period. Headache, diarrhoea, palpitation and dizziness were the commonly reported adverse effects during the study. No adverse effect led to discontinuation of therapy. The present study suggests that cilostazol is an effective therapeutic option with an acceptable tolerability profile for the treatment of IC in patients with PAD.
