Pharmaceutical preparation technology refers to the process of combining pharmaceutical active ingredients with excipients to prepare preparations suitable for administration through a series of processes and methods. The goal of pharmaceutical preparation technology is to ensure the stability, effectiveness and safety of drugs in the process of taking.
Pharmaceutical preparation technology includes the following aspects:
1, drug selection: according to the characteristics of the disease and treatment needs, choose the appropriate active drug ingredients.
2. Study on drug stability: Determine the stability of drugs in the preparation, including photosensitivity, temperature sensitivity, humidity sensitivity and other factors. In view of the instability problem, appropriate technology and auxiliary materials can be used for protection.
3. Selection of dosage forms: according to the nature of the drug and the treatment needs, choose appropriate dosage forms, such as tablets, capsules, injections, solutions, emulsions, gels, patches, etc.
4. Selection of excipients: Select suitable excipients, such as fillers, adhesives, dispersants, sustained-release agents, etc. So as to achieve the required drug release characteristics and physical characteristics.
5. Preparation process development: design and optimize the preparation process, including mixing, drying, tabletting, coating, filling and other steps to ensure the quality and stability of the preparation.
6. Quality control: Conduct quality control tests on the preparation, including drug content, solubility, dissolution and microbial limit, to ensure that the preparation meets the requirements of Pharmacopoeia and related standards.
The duty of a pharmacist
1. drug treatment advice: pharmacists work closely with doctors and other health care professionals to provide drug treatment advice to patients. Pharmacists will formulate the most appropriate drug treatment plan according to the patient's condition, drug selection, dosage, medication route and other factors.
2. Drug dispensing: Pharmacists are responsible for accurately dispensing drugs needed by patients to ensure the accuracy and safety of drugs. Pharmacists will check doctors' orders, check the labels and trade names of drugs, and prepare or distribute appropriate doses of drugs.
3. Drug consultation and education: pharmacists provide patients with detailed information about drugs, including usage, side effects and interactions, so that patients can use drugs correctly and safely. Pharmacists can also answer patients' questions about medication, and provide medication advice and lifestyle guidance.
