Why do different kinds of medicines have different number of tablets per packet? For some, there are 4 tablets for a pack, and for some there are 10.
There may be different reasons for it.
The main reason why it is done, is to cover the complete course of medication. e.g. if the course of a medication, especially antibiotics is completed in four doses, it is most likely that the tablet shall be marketed in blister packs of four tablets. This is done primarily to avoid overdosage and unprescribed usage of the drug. On the other hand, any OTC medication like acetaminophen/paracetamol or multivitamins can come in blister packs of 10/15/20/30 as they can be taken over the counter and whenever needed, till their expiry.
Secondly, the MRP per tablet of smaller pack size is higher (although manufacturing costs are also higher). Some pharma companies may market the same salt in smaller pack sizes to improve their margins per tablet.
Thirdly, there are certain combinations of different drugs that need to be taken in a particular sequence. Usually this sequence is of two or three different salts, each to be taken one after the other. In such cases, the complete course is packed in a single blister pack that usually contains three or max four tablets.
Smaller packs of medicines are consumed quickly and the patient has to go to medicine shop repeatedly. This increases the sales volume of the pharma company. Again, profiteering.
