Formulation and Evaluation of Immediate Release Tablet of Telmisartan

Introduction Medications are only one part of a successful treatment plan. They are appropriate when they provide benefit, improve function and have either no or mild, manageable side effects. Importantly, medications (even if natural) are chemical substances not expected in the body, and as such have side effects. Some of the side effects might be unknown. The use of medications or drugs for any purpose requires patient consent. Pharmacotherapy can be defined as the treatment and prevention of illness and disease by means of drugs of chemical or biological origin. It ranks among the most important methods of medical treatment, together with surgery, physical treatment, radiation and psychotherapy. Drug Delivery System (DDS) is defined as a formulation or a device that enables the introduction of a therapeutic substance in the body and improves its efficacy and safety by controlling the rate, time, and place of release of drugs in the body. This process includes the administration of the therapeutic product, the release of the active ingredients by the product, and the subsequent transport of the active ingredients across the biological membranes to the site of action. Drug delivery system employed can control the pharmacological action of a drug, influencing its pharmacokinetics and subsequent therapeutic profile. Drug delivery system is an interface between the patient and the drug (Jain et al., 2008).
