The trial is designed to assess the safety and investigation of the efficacy of a single oral dose of bisoprolol (Nerkardou - Nerhadou) oral dissolvable film (ODF) 5 & 10 mg, and patients' compliance in the treatment of essential hypertension. This is a Phase IV, open-label, single-arm, prospective trial where subjects will receive:

1. Bisoprolol (Nerkardou) at an initial dose of 5 (mg) milligrams once daily for 2 weeks.
2. If the blood pressure would be greater than or equal to 130/80 mmHg after 2 weeks, then the dose will be titrated to 10 mg once daily (non-responders). Dose-Titration will be done at any follow-up visit based on the response.
3. The total duration of study treatment will be 12 weeks ±2 days, and the total sample size of the study will be 406 participants.

The trial is designed to assess the safety and investigation of the efficacy of a single oral dose of bisoprolol (Nerkardou - Nerhadou) oral dissolvable film (ODF) 5 & 10 mg & patients' compliance in the treatment of essential hypertension. This is a Phase IV, open-label, single-arm, prospective trial where subjects will receive:

The subject will initially administer once daily 5 mg bisoprolol (Nerkardou) oral dissolvable film (ODF) for 2 weeks. After the assessment of the subject being a responder, study medication will be maintained till week 12. Response will be assessed for each patient every 2 weeks and dose-titration will be done based on the response and PI decision at any visit. Then, for responders, once daily 5 mg bisoprolol (Nerkardou) oral dissolvable film (ODF will be administered for the subsequent 2 weeks. For non-responders once daily 10 mg bisoprolol (Nerkardou) oral dissolvable film (ODF) will be administered for the subsequent 2 weeks. For those who are still not responding to the higher dose will be shifted to other alternatives according to their merit and they will be included to intention to treat.

A responder is defined by BP response, which is represented in the form of a ≥20 mmHg decreases in sitting through SBP and a ≥10 mmHg decreases in sitting through DBP, or a sitting through SBP of <130 mmHg and a sitting through DBP of <80 mmHg.

The total duration of study treatment will be 12 week (±2days). (Flow chart of trail design Appendix III) and the total sample size of the study will be 406 participants.

The trial has a duration of approximately 14 weeks, including:

1. Screening (assessments to determine eligibility for entry into the trial, occurring within 14 days to day 1 before treatment initiation (week -2) to (week 0).
2. Treatment duration (5 mg or 10 mg bisoprolol (Nerkardou) based on the response) (duration of 12 weeks); from Day 1 (week 1) to the end of day 84 ±2days (week 12 ±2days)
3. Premature withdrawal/ Early Discontinuation

Inclusion Criteria:

1. The participant is willing and able to give informed consent for participation in the trial.

   • Grade 1 hypertension: SBP 140 to 159mmHg and/or DBP 90 to 99mmHg
   • Grade 2 hypertension: SBP 160 to 179mmHg and/or DBP 100 to 109mmHg at screening.

5. Non-responders to the 1ST line of therapy for hypertension other than beta blocker and can be safely switched to Bisoprolol (Nerkardou) according to PI decision.

6. Subject doesn't have other comorbidity according to the assessment of the medical history, electrocardiogram (ECG), echocardiogram vital signs, physical examination, and laboratory results.

7. Subject with heart rate (HR) ≥ 80 (BPM) at baseline.

8. Female subjects in childbearing period, and not on a reliable contraceptive method must adhere to the recommended contraceptive methods as detailed in Appendix I.
