Biopharmaceutics and Biochemistry

Biopharmaceutics is the study which shows how the drug absorption rate is affected by various factors like physical and chemical properties of the drug, the dose form of the drug and the route through which the drug is administered. Drugs are substances intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease. Drugs are given in a variety of dosage forms or drug products such as solids (tablets, capsules), semisolids (ointments, creams), liquids, suspensions, emulsions, etc, for systemic or local therapeutic activity. Drug products can be considered to be drug delivery systems that release and deliver drug to the site of action such that they produce the desired therapeutic effect and are also designed specifically to meet the patient's needs including palatability, convenience, and safety.
