Brief Summary:
  • Evaluation of the non inferiority of Meclin (meclizine) versus Dramin (Dimenhydrinate) to treat the symptoms of acute vertigo from peripheral origin after up to 4 weeks of treatment;
  • Evaluation of impact on quality of life in vertigo;
  • Compare the intensity of daytime sleepiness in the two treatment groups;
  • Compare the efficacy of drugs in relieving each of the 10 symptoms that make up the VS;
  • Compare the duration of treatment in both treatment groups;
  • Compare Adehence;
  • Compare the level of satisfaction from each group from the investigators and the subjects;
  • Adverse events;

Condition or disease Intervention/treatment Phase
Vertigo, Peripheral Drug: Meclizine Drug: Dimenhydrinate Phase 3

Detailed Description:

It is a prospective interventional study arms parallel , active -controlled , non-inferiority . Participants selected for the study should be of both sexes , aged over 18 years and less than 65, which meet all the inclusion criteria and did not fit any exclusion criteria , and agree to all the purposes of the study. Participants are divided into two according to the randomization treatment groups 1:1.

The study should take no longer than 30 days to be completed with the amount of 6 visits (7±2 days): V0 radomization; V1, V2, V3 andV4(FV) are Evaluation visits and One Follow up visit 7±2 days after the Final Visit.

Official Title: " National, Phase III, Radomized, Double-Blind, Double -Dummy, Controlled, Parallel to Evaluate Non Inferiority of Meclin® (Meclizine Chlorhydrate) Versus Dramin® (Dimenhydrinate) Soft Gel Capsules in the Control of Acute Vertigo Symphtoms From Peripheral Origin"
Study Start Date : November 2016
Estimated Primary Completion Date : April 2017
Estimated Study Completion Date : December 2017

Arm Intervention/treatment
Experimental: Meclizine
Meclizine 25 mg, tablets
Drug: Meclizine
25 mg, 3 times per day up to 30 days
Other Name: Meclin

Active Comparator: Dimenhydrinate
Dimenhydrinate 50 mg, soft Capsgel
Drug: Dimenhydrinate
50 mg, 3 times per day up to 30 days
Other Name: Dramin

Primary Outcome Measures :
  1. Vertigo Score (VS) [ Time Frame: up to 30 days ]
    Evaluation of non inferiority by measuring 10 symptoms of vertigo : distasia and instability when walking ; totter ; spinning sensation; tendency to fall; Continuous floating feeling ; floating sensation to change position ; floating sensation to bow down ; floating sensation when standing up ; floating sensation traveling on any means of transport; floating sensation with head movement ; floating sensation with eye movement. Each symptom is graduated in a semi -quantitative 5-point scale : 0 = no symptoms ; 1 = mild symptoms ; 2 = moderate symptoms ; 3 = strong symptoms ; 4 = very strong symptoms in all visits that the subject accomplishes.

Secondary Outcome Measures :
  1. Quality of Life Questionnaire DHI - Dizziness Handicap Inventory, validated for the Brazilian population [ Time Frame: up to 30 days ]
    Evaluation of life quality

Other Outcome Measures:
  1. Stanford and Epworth Sleepiness Scale [ Time Frame: up to 30 days ]
    Evaluation of somnolence (baseline measurement)

  2. Variation of the intensity of each of the 10 symptoms [ Time Frame: up to 30 days ]
    Evaluation of the variation of the intensity of each of the 10 symptoms that make up VS, along the visits

  3. Duration of treatment (days from V0) [ Time Frame: up to 30 days ]
    Evaluation of the duration of tratement from each group

  4. Adherence rate to treatment [ Time Frame: up to 30 days ]
    Evaluation of adherence rate from each group throughout the study

  5. Visual analogue scale (VAS) for subjects and for investigators [ Time Frame: up to 30 days ]
    For the subjective assessment of the participant and investigator's research on the treatment applied in 1,2,3 visits and final (VF);

  6. Participants Percentage with any symptoms classified as moderate (score ≥2) [ Time Frame: Since last Visit ]

    Evaluation of participants percentage with any symptoms classified as moderate on the VS Scale on the follow-up visit, held 7 ± 2 days after the final inspection (VF).

    through the study.

  7. Analysis of Adverse Events [ Time Frame: After the signature of SICF ]
    Evaluation of any Adverse Event ou Serious Adverse Event recorded after the signing of the Informed Consent ( IC) and until the end of the study

  8. Clinical and Physical findings [ Time Frame: After the signature of SICF ]
    Evaluation of any changes in clinical / physical assessment findings since baseline
