All pharmaceutical products are formulated to specific dosage forms for drugs to be effectively delivered to patients. Typical pharmaceutical dosage forms include oral tablets, capsules, solutions, suspensions, topical ointments, gels, and solutions, and injections for intravenous (IV), intramuscular (IM), or subcutaneous (SC) administration. In addition, various drug delivery systems have been developed for transdermal, intranasal, and pulmonary deliveries. Different dosage forms require different pharmaceutical technologies and usually present different technical challenges for formulation development.
