Brief Summary:
The use of both levamisole & Isoprinosine has both synergistic and complementary effect in the treatment of COVID 19 infection

Condition or disease Intervention/treatment Phase
Respiratory Tract Infections Drug: Levamisole and isoprinosine Drug: Azithromycin and hydroxychloroquine Phase 3

Detailed Description:

Study design: Randomized controlled trial, randomization by closed envelope technique Informed consent will be written for each patient of either group

At the beginning of the study all patients will have the following investigations done: CBC with differential, ESR, PCR for COVID 19, D dimer and CT chest and confirmed cases will included in the study

Pregnant and lactating women together with children with other comorbidities will be excluded from the study

Study groups:

Duration of the study is 4 weeks

Both groups with persistent COVID 19 symptoms that require hospitalization

Group 1: 30 patients with confirmed COVID19 infection and sharing clinical features like fever, malaise, sore throat, runny nose, persistent cough &dyspnea, requiring hospitalization

Group 2: control group: 30 patients

Treatment endpoint • Cure of patients: Improvement of symptoms Laboratory findings ESR and total leucocytic count returning to normal PCR negative Radiological improvement

• Worsening of symptoms or fatalities
