Case Summary

An anonymous complainant alleged that an advertisement for Tabphyn MR (tamsulosin) included a hanging comparison, ‘Spend fewer pennies on the treatment of BPH’, and was misleading. The advertisement, published in Prescriber on 5 February, referred to Genus and ProStrakan and the matter was taken up with both companies.

The complainant provided a copy of a price list from a company specialising in generic medicines which showed a tamsulosin MR product (Stronazon) with an invoice price of £3.69 per pack of 30x400mg and a promotional price of £3.32.

Genus explained that it held the marketing authorization for Tabphyn. The product had been licensed to ProStrakan in March 2006. Genus had had no involvement in promotion of any kind for the product after March 2006 and had no knowledge of the advertisement in question.

The Panel noted the ProStrakan corporate logo and website address appeared in the advertisement which also included the statement ‘Further information is available on request from: Genus Pharmaceuticals Ltd’. Both medical information enquiries and adverse event reports should be directed to Genus. It thus appeared from the advertisement that Genus had a current role beyond being the marketing authorization holder. The Panel considered that Genus was jointly responsible with ProStrakan for the advertisement under the Code.

The Panel ruled a breach of the Code as it considered that the claim ‘Spend fewer pennies on the treatment of BPH’ was a hanging comparison. It was not clear whether the comparison was with other generic or branded formulations of tamsulosin or all other treatments for BPH.

The Panel noted ProStrakan’s submission that the price list used by the complainant was not in the public domain. The Panel also noted that at the date of the advertisement, according to data available to ProStrakan, Tabphyn MR was the least expensive tamsulosin product at NHS list price - £7.99 for one month’s treatment. The basic price for tamsulosin 400mg modified release capsules (30) was £8.68 (Drug Tariff January 2007). The Panel considered that although it might be possible to buy tamsulosin at less than the NHS list price, it was not unreasonable for companies to base price comparisons on prices that were publicly available.

Thus the Panel ruled no breach of the Code.
