The clinical effect following 12 mg sublingual tizanidine was larger (4-5 units on the Ashworth scale) and more sustained (up to 18-20 hours post-dose) than was seen for 8 mg tizanidine (earlier study, Protocol C2/5/TZ:MS-03z). This study also reconfirmed that the increased improvement in next-day reduction of spasticity following overnight sublingual tizanidine dosing is not accompanied by a concomitant increase in next-day somnolence.\n\nThis study, a 12 month open label extension, will allow those patients who successfully completed Protocol C2/5/TZ-MS-05 and who found tizanidine to be beneficial, to continue treatment under close medical supervision. The study will provide long-term (12 months) clinical efficacy and safety data re: the use of once daily sublingual tizanidine, administered at night, just before bedtime.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Successful completion of previous protocol, Study C2/5/TZ:MS-05\n* Have a definitive diagnosis of Multiple Sclerosis\n* Patients may be allowed to take other anti-spasticity medication during the study (other than Baclofen pump)as per their individual daily dosing regimen, with the following qualification: (1) No dose after 18:00 on any study day (2) No dose at all on a clinic evaluation day\n* Females must agree to use a medically accepted form of birth control, be surgically sterile, or be two years post-menopausal.
