MEDICINAL QUANTITIES can be referred to as DOSES, which is a 5 letter word. Medicinal quantities are the amount of medicine that is prescribed to a patient for a certain period of time. It is important to take the correct dosage of medication in order to ensure that the patient receives the full benefit of the drug. The dosage of a drug can vary depending on the individual's age, weight, and other factors. Taking too much or too little of a drug can have serious consequences, so it is important to follow the instructions of a doctor or pharmacist when taking any type of medication.
