Arms Assigned Interventions
Experimental: 1
Treatment Sequence 1: MK0524 + placebo, MK0524 + montelukast, placebo, placebo, placebo + montelukast
 Drug: Comparator: MK0524 + placebo
Two 150 mg MK0524 tablets + one placebo tablet in the matching image of montelukast 10 mg once daily for 3 weeks
Drug: Comparator: MK0524 + montelukast
Two 150 mg MK0524 tablets and one 10 mg montelukast tablet once daily for 2 weeks
Drug: Comparator: placebo + montelukast
Two placebo tablets in the matching image of MK0524 150 mg and one 10 mg tablet montelukast once daily for 2 weeks
Drug: Comparator: Placebo
During the double-blind treatment periods, patients receive either two placebo tablets in the matching image of MK0524 150 mg or one placebo tablet in the matching image of montelukast 10 mg in a crossover manner. During the washout period before the crossover to the opposite treatment sequence, patients receive two placebo tablets in the matching image of MK0524 150 mg and one placebo tablet in the matching image of montelukast 10 mg once daily for two weeks.
Experimental: 2
Treatment sequence 2: Placebo, montelukast, placebo, MK0524, MK0524 + montelukast
 Drug: Comparator: MK0524 + placebo
Two 150 mg MK0524 tablets + one placebo tablet in the matching image of montelukast 10 mg once daily for 3 weeks
Drug: Comparator: MK0524 + montelukast
Two 150 mg MK0524 tablets and one 10 mg montelukast tablet once daily for 2 weeks
Drug: Comparator: placebo + montelukast
Two placebo tablets in the matching image of MK0524 150 mg and one 10 mg tablet montelukast once daily for 2 weeks
Drug: Comparator: Placebo
During the double-blind treatment periods, patients receive either two placebo tablets in the matching image of MK0524 150 mg or one placebo tablet in the matching image of montelukast 10 mg in a crossover manner. During the washout period before the crossover to the opposite treatment sequence, patients receive two placebo tablets in the matching image of MK0524 150 mg and one placebo tablet in the matching image of montelukast 10 mg once daily for two weeks.
