Pidotimod: In-depth review of current evidence.

Pidotimod, an immunostimulant, is researched for over two decades. Current evidence indicates its utility in a variety of indications in children as well as in adults. Its immunostimulant activity has been firmly established in the management of recurrent respiratory infections in children with or without asthma. Compared to standard of care alone, addition of pidotimod to standard of care significantly prevents the recurrences and reduces the severity and duration of acute episodes, ultimately resulting in reduced visits to pediatric clinics and lower absenteeism at school. In adults, pidotimod is effective in the prevention and treatment of acute infectious exacerbations of chronic bronchitis and chronic obstructive pulmonary disease (COPD). Further, it has been evaluated in indications such as pneumonia, hand-food-mouth disease, bronchiectasis, and chronic idiopathic urticaria. From a total of 32 studies conducted in child (24 studies) and adult (8 studies) population, this in-depth review discusses the current evidence of pidotimod. With further exploration, the immunostimulant activity of pidotimod might be extended to different immunological disorders.

Efficacy and Tolerability of Olmesartan, Telmisartan, and Losartan in Patients of Stage I Hypertension: A Randomized, Open-label Study.

OBJECTIVES: To compare the efficacy and tolerability of losartan, telmisartan, and olmesartan as antihypertensive agents and evaluate and compare their effects on lipid profile and blood glucose. MATERIALS AND METHODS: This was a randomized, open-label, parallel-group, comparative study conducted in sixty patients of Stage I hypertension. The eligible patients were randomly allocated into three treatment groups: (1) Tablet olmesartan (20 mg), (2) Tablet telmisartan (40 mg), and (3) Tablet losartan (50 mg). Blood pressure (BP) was assessed at an interval of 2 weeks for 3 months. Fasting blood glucose (FBG) and lipid profile were estimated at baseline and then at 12 weeks. RESULTS: Olmesartan and telmisartan were more efficacious than losartan in reducing diastolic BP (DBP). There was a statistically significant decrease in mean blood glucose level (P < 0.02) after 12 weeks of treatment in telmisartan group when compared to baseline. Serum total cholesterol, triglycerides, and low-density lipoproteins decreased significantly after 12-week treatment with olmesartan and telmisartan. CONCLUSIONS: The most efficacious drug in reducing BP is Olmesartan whereas telmisartan and losartan show equal efficacy. Telmisartan shows the most favorable effects on FBG and lipid profile.
