Definitions

• the present invention is related to a novel drug pack, in general with the same basic construction as the tablet cards or "blister packs" which today are in extensive use.
• These consist usually of a card of plastic material which one side thereof is provided with a number of blisters for receiving therein a tablet and which on the other " side thereof has a metal foil attached to the card, which foil seals the underside of the blisters. A tablet may be released by depressing the blister thus that the tablet breaks the foil.
• The.se may be two or more substances which are used in the treatment of the same disease condition, or which are used in the treatment of different disease conditions.
• the substances may be substances having mutually complementary or synergistic effect.
• the effects of the respective substances are often unrelated to each other.
• Intermediate forms occur where there is a varying degree of connection between different disease conditions and the effects of the drugs.
• An example of treatment of the same disease condition is the treatment of hypertension where substances with a direct activity on heart and vessels, such as beta blockers and calcium antagonists, may be used in combination with each other and with diuretics.
• Another example is treatment of pain where different analgesics, sedatives and muscle relaxants may be combined.
• each dosage unit e.g. tablet contains a plurality of active substances.
• Combination preparations are however frequently connected with limitations and drawbacks which causes then often not to provide the best possible treatment.
• a significant problem is the insufficient flexibility of combination preparations. Different patients may require different combinations of substances or different dosages of the various substances.
• the effect and duration of the various substances may be so different that simultaneous administration at each dosage time is not desirable.
• a substance may be indicated for supply several times per day while another substance is indicated for administration once a day, e.g. at bedtime.
• DE 2 103 694, GB 2079 250 and US 4254871 are examples of designs which are intended to facilitate the handling of dosage units of drugs. -All however, require supply of a separate holder, base plate or frame in which dosage packs are placed. Further, they do not give any solution to the special problem of ensuring concurrent administration of two or more drugs at each dosage occasion.
• the present invention has the purpose of providing a drug pack which enables simplified and safer treatment with two or more drugs which allows for a high degree of flexibility for different combinations and dose regimens and which does not require special holders or the like for dosage units or packs thereof. Description of the invention
• the present invention is thus related to a drug pack comprising a first card which on the upper side thereof is provided with a number of blisters for receiving therein drug dosage units, such as tablets or capsules, and which on the lower side thereof has a breakable underfoil attached thereto, through which dosage units may be released.
• the drug pack is characterized in that the first card has a number of openings arranged thus that blisters belonging to a second drug pack may be introduced through the openings from the lower side of the first card to the formation of a combination pack, wherein the second drug pack comprises a second card provided with such blisters, openings corresponding to the blisters of the first card and a second underfoil.
• the invention enables the doctor, when treatment with a plurality of drugs is desired, to prescribe dispensing to the patient a combination pack assembled from two or more packs.
• the pack In wholesale the pack is intended usually to be provided separately, which makes it possible when desired to provide the pack separately to the patient when treatment with a plurality of drugs is not intended.
• a functioning pack of the invention can be made with an unbroken underfoil under the openings of the card, whereby, on assembling of two cards, the underfoil of the upper card is broken by the blisters of the lower card and whereby, on release of a dosage unit, the underfoil of the lower card is broken at the same time as the underfoil of the upper card is broken. It is however, preferred to construct the pack thus that the openings in the card extend through the underfoil as well, which will facilitate the assembling of packs and the releasing of dosage units.
• each opening in the first card is located at a shorter distance from one blister than from other blisters in said first card.
• blisters from the first and the second cards will be located adjacent to each other in pairs, which makes it evident to the patient that the dosage units therein are to be taken out at the same time, preferably by simultaneous depression of the two blisters.
• the pack is provided with attachment means for attachment of the first card to the second card.
• attachment means are preferably designed as snap locks, for example in the form of tiny blisters on one card which may be introduced into holes or blisters on the second card and be locked therein.
• the attachment means as an adhesive material which is coated on or which on assembling of two packs is brought into contact with the underfoil of the first card and which will adhere to the underfoil and to the upper side of the second card.
• the adhesive material may for example comprise strips of tape with adhesive compound on both sides, suitably provided with a releasable protective sheet, said strips being placed on areas- of the underfoil which are not occupied by blisters or hoTes in the card. It is also possible to shape the blisters which are to receive the drug in such manner that the blisters of the lower card will lock into the holes of the upper card.
• Alternative attachment means may be loose buttons or pins which may be used for assembling the cards through holes therein, or rails that may be slipped over the edges of the assembled cards. Such buttons or rails are suitably packaged together with the pack. It is also possible.to provide a simple apparatus to be used in the pharmacy for assembling two cards.
• a combination pack comprising a first and a second drug pack as described above is a further aspect of the invention.
• a such combination pack is thus prepared in the pharmacy, but it is not out of the question for especially frequent combinations for combination packs to be prepared already by the manufacturer.
• a combination pack according to the invention consists in a preferred embodiment of the invention of a first and a second drug pack with substantially the same construction.
• the second drug pack is preferably rotated one half revolution, in the plane thereof, in relation to the first drug pack, with which it is assembled.
• This embodiment also anables a simple and effective arrangement of attachment means, where each card is provided with pairs of one hole and one blister placed close to each other in such way that after rotation of one pack one half revolution, each blister will be located in register above or below a hole into which it can be pressed and locked.
• a method for treatment of disease is a further aspect of the invention.
• drugs are prescribed or administered to patients from a combination pack as above.
• a drug pack which has blisters and/or dosage units corresponding only to certain of the holes in another drug pack with which it may be assembled. Thereby there may be achieved alternating treatment with one or more drugs depending on the therapeutic need. It is also within the scope of the invention for the blisters in one and the same card to contain dosage units of different drugs or different amounts of drugs.

• a (first) drug pack comprising a card 1 of transparent plastic material having an approximate thickness of 0.25 mm, which card has, through vacuum molding, been provided on the upper side thereof with eight blisters 3 disposed in two columns in the length direction of the card.
• a breakable underfoil 4 consisting of aluminium having the approximate thickness of 20 ⁇ r ⁇ is attached to the lower side of the card through heat sealing against the plastic material of the card.
• the underfoil covers at 4a the lower side of the blisters 3 in each of which is placed a tablet 5 of a drug provided with the denotation A on the tablet (drug A).
• the pack 1 is in accordance with a conventional blister pack for drugs.
• the card and the underfoil has eight openings 6 of such size and shape that a blister resembling blisters 3 can be introduced therethrough.
• the card 2 further has six tiny circular blisters 7 which are not covered by the underfoil and which is shaped to provide a snap lock with similar blisters on a second card.
• a such second card 8 has an appearance identical to the appearance of card 2 and is shown in Fig. 3 rotated one half revolution in relation to the first card 2, with which it is subsequently assembled.
• the card 8 has eight blisters 9 which extend up through the openings 6 in card 2.
• card 2 has an underfoil 10 and, not visible in Fig. 3, eight opeinings 11 through the card and the underfoil, said openings in register with each of blisters 3.
• blisters 9 is placed each one tablet 12 of a drug denoted B on the tablet (drug B).
• dosage units of drug A and drug B are located in the combination pack adjacent to each other in pairs.
• a first drug pack 13 has three blisters 15 for a drug, said pack being assemblable with a second drug pack 14 having six blisters 16 for a drug arranged in pairs.
• the pack 13 has three holes 17 each corresponding to two blisters 16 arranged in pairs, while pack 14 has three holes 18 corresponding to each of blisters 15.
• a pack which is mainly in accordance with the pack 1 in Fig. 1, has no snap locks and has instead three strips 22 of adhesive material provided with a protective sheet 21.
• the protective sheet 21 is removed from the pack that will be placed above, and the adhesive material is brought to adhere to the upper side of the other pack.
• a frame printed around one blister and one hole said frame provided with a digital denotation and indicating a combination dosage to be taken on one and the same occasion.
• the digital denotation may in a known manner be replaced with other denotation such as e.g. "morning", "evening” and/or day of the week.
• the pack shown in Fig. 7 corresponds in general to the pack in Fig. 1 and is thus designed to be assemblable with a similar pack.
• the pack is however modified thus that the attachment means are designed as pairs of one blister 24 and one hole 25 where each blister 24 in one of the packs will be in register below, and on assembling will be locked into a hole 25 in the other pack.
