Outcomes
Primary outcome [1] 288399 0
Nebulised verapamil used as a treatment agent is associated with a reduction of Pulmonary Arterial Pressure (PAP).
Patients will undergo transthoracic Echocardiographic examination with evaluation of systolic PAP by echocardiography equipment
Timepoint [1] 288399 0
at baseline and 1 hour after the intervention
Primary outcome [2] 288404 0
Evaluation of EF (Ejection Faction) by transthoracic echocardiography equipment
Timepoint [2] 288404 0
at baseline and 1 hour after the intervention
Primary outcome [3] 288405 0
Evaluation of RV (Right Ventricular) size and RV TAPSE (Tricuspid Annular Plane Systolic Excursion) by transthoracic echocardiography equipment
Timepoint [3] 288405 0
at baseline and 1 hour after the intervention
Secondary outcome [1] 300052 0
Nebulised verapamil used as a treatment agent is associated with a reduction of Spirometric Parameters (FEV1, FVC and FEV1/FVC) that evaluated by spirometry equipment
Timepoint [1] 300052 0
at baseline and 30 minutes after the intervention
Secondary outcome [2] 300053 0
Nebulised verapamil used as a treatment agent is associated with a reduction of O2 Saturation that evaluated by pulse oximetry.
Timepoint [2] 300053 0
at baseline and immediately after the intervention
Secondary outcome [3] 300054 0
Blood pressure is measured by blood pressure cuff because of possible hypotension as the side effect associated with the intervention.
Timepoint [3] 300054 0
at baseline and immediately after the intervention
Secondary outcome [4] 300066 0
Heart rate is measured because of possible bradycardia as the side effect associated with the intervention.
Timepoint [4] 300066 0
at baseline and immediately after the intervention

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The treatment and control groups will remain blinded to the treating clinicians. The clinical trial assistant will be unblinded for the preparation of the daily treatments.
The treatment allocation was randomized by a pharmacy technician who is not directly involved in the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomisation table from a statistic book
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
