In modern pharmaceutical packaging, two major trends are becoming more apparent: single-dose packaging and automated packaging. The drug in the unit dose package is equivalent to a single dose. They may also contain sufficient doses only within 24 hours.
Since the 1960s, the United States has adopted unit dose dispensing system(UDDS), in which the dispensing personnel package the solid preparations (such as tablets, capsules, etc.) of the various drugs that the patient needs to take, and heat-seal the aluminum foil or the plastic bag by a sub-packaging machine and package them separately. The package is marked with the name of the drug, the indications, the dosage, the precautions, etc., so that the pharmacist, the nurse and the patient can check it by themselves. It avoids the shortcomings that the patient has not been able to identify and cannot check, which is convenient for the patient to take, prevent the wrong medicine or repeated medication, and ensure the correctness, safety and economy of the medicine.
Blister packs are commonly used as unit dose packs for pharmaceutical tablets, capsules or lozenges. This type of packaging is more portable than a bottle. Patients and caregivers can use the amount of medication left to determine if they are taking the drug.
Unit dose packaging has evolved from the medical field to a variety of other industries, including cosmetics. Products such as lotions, gels, cosmetics, creams and soaps are sold effectively using this packaging option. It is used for packaging one-time cosmetics, both retail and as a gift, which are easy to carry and use.
