Introduction to Pharmaceutics

Pharmaceutics is the science and art of preparing, dispensing, and evaluating drugs for use.
It involves transforming a drug substance into a dosage form suitable for administration.
It aims to ensure drug safety, efficacy, and patient acceptability.

Dosage Forms

Different dosage forms suit various routes of administration and patient needs.
Examples include tablets, capsules, powders, suspensions, ointments, and injectables.
The best dosage form depends on the drug's properties, desired route, and patient characteristics.

Drug Release Mechanisms

Controlled release systems deliver drugs at a set rate over an extended period.
This maintains therapeutic levels and decreases dosage frequency.
Examples include matrices, liposomes, and implants.

Formulation Design Principles

Designing formulations involves choosing the right materials and processes for desired drug properties.
Key considerations include drug solubility, stability, and bioavailability.
Methods like dissolution testing, in vitro, and in vivo analyses evaluate formulation performance.

Drug Delivery Systems

Drug delivery systems enhance drug effects by controlling release, targeting specific sites, or improving patient compliance.
Examples include nanoparticles, liposomes, and microspheres.
These systems can improve efficacy and reduce side effects.

Excipients

Excipients, or inactive ingredients, are essential components of dosage forms.
They function as fillers, binders, disintegrants, and lubricants.
Selecting excipients is crucial for product quality and stability.

Pharmaceutical Manufacturing

Drug manufacturing follows strict quality control procedures, established protocols, and regulatory compliance.
Processes include blending, granulation, coating, and packaging.
Standardized procedures ensure consistent product quality.

Formulation Stability

Formulation stability is crucial for preserving drug efficacy and safety over time.
Factors influencing stability include temperature, light, humidity, and chemical reactions.
Stability studies evaluate degradation rates and determine appropriate storage conditions.

Biopharmaceutics

Biopharmaceutics investigates the link between drug properties and bioavailability.
Bioavailability is the rate and extent a drug is absorbed and available at the site of action.
Factors like drug dissolution rate, absorption, and first-pass metabolism impact bioavailability.

Manufacturing Quality Control

Quality control ensures consistent quality and safety throughout manufacturing.
Steps involve testing raw materials, finished products, and intermediates against predefined criteria.
Regulatory standards define acceptable contaminant and impurity levels.
