  • Patent number: 4258027
    Abstract: The invention disclosed provides a multi-fractionable tablet structure initially configurated in a unitary dosage while having readily severable sub-dosage units as components thereof. Score markings are positioned variously about the tablet such as along the top and bottom surfaces thereof. Additionally, score markings may appear along opposite vertical side surfaces of the tablet. Special placement of the score markings readily permits alternatively an accurate equal bisectional or trisectional fracture of the tablet as may be desired for patient consumption.
