Market Drivers

• Rise in Hypertension and Edema Cases: According to WHO, over 1.3 billion adults suffer from hypertension globally, increasing demand for diuretics like CLOROTEKAL.
• Aging Population: Elderly demographic growth amplifies the need for antihypertensive therapies.
• Cost-Effectiveness: Chlorothiazide remains a low-cost option compared to newer diuretics, notable in resource-limited settings.
• Brand & Patent Dynamics: CLOROTEKAL, being generic, faces little patent restriction, facilitating broad access and price competitiveness.

Market Challenges

• Competition from Novel Agents: Thiazide-like diuretics (chlorthalidone, indapamide) offer improved efficacy, affecting CLOROTEKAL's market share.
• Regulatory Hurdles: Variations in approvals and labeling standards across countries impact distribution.
• Side-Effect Profiles: Electrolyte imbalances and metabolic disturbances limit usage in certain populations.
