  The invention concerns novel pharmaceutical preparations containing A) an extract of the mollusc Perna canaliculus, a mussel which is found on the shores of New Zealand, and B) a pharmaceutically active substance, especially medicaments having anti-phlogistic, antipyretic and/or analgetic action, which, when taken per se, may cause as a side effect irritation of the gastro-intestinal mucosae and possibly the formation of ulcers. The addition of a mollusc extract according to A) to the said medicaments has a gastro-protective action, in that the occurence of the said side effects is prevented or diminished. The component A) is preferably used as a dry powder of the whole of the flesh of the mollusc or a dry powder obtained from the gonads thereof. In a typical preparation according to the invention an extract of the gonads is e.g. combined with acetyl-salicylic acid. The preparations may contain the 2 components in one and the same dosage unit form, e.g. a capsule or in 2 different ones, e.g. a capsule and a tablet. The invention also includes a method for preventing, alleviating or a treating gastro-intestinal irritation or ulcer formation by administering an effective amount of the mollusc extract as defined under A.

  本发明涉及一种新型药物制剂，其中含有 A）新西兰海岸发现的一种软体动物 Perna canaliculus 的提取物和 B）一种药物活性物质，特别是具有抗咽喉炎、解热和/或镇痛作用的药物。在上述药物中添加 A)软体动物提取物具有胃肠道保护作用，可以防止或减少上述副作用的发生。A)成分最好是软体动物整个肉的干粉或从其生殖腺中提取的干粉。在本发明的典型制剂中，性腺提取物与乙酰水杨酸等成分结合使用。制剂可将这两种成分以一种相同的剂量单位形式（如胶囊）或两种不同的剂量单位形式（如胶囊和片剂）包含。 本发明还包括一种预防、减轻或治疗胃肠道刺激或溃疡形成的方法，通过服用有效量的软体动物提取物如A.

  (EN) The invention relates to the use of vitamin PP compounds and/or compounds with anti-pellagra activity such as for example nicotinic acid (niacin), and nicotinamide (niacin-amide, vitamin PP, vitamin B3) for the reduction, elimination or prevention of side-effects of different degrees as well as for neutralization of acute side-effects in immunosuppressive or cancerostatic chemotherapy or diagnosis, especially with substituted pyridine carboxamides, whereby compounds from the series of formula (I), as well as combination medicaments with an amount of compounds with vitamin B3 and/or anti-pellagra activity and chemotherapeutic agents are especially considered in the mentioned chemotherapies and indications.(FR) L'invention concerne l'utilisation de composés de vitamine PP et/ou de composés présentant une activité anti-pellagre, par exemple l'acide nicotinique (niacine) et le nicotinamide (amide nicotinique, vitamine PP, vitamine B3), et permettant de prévenir, de réduire, ou d'éliminer des effets secondaires plus ou moins graves. Ces composés permettent également de neutraliser les effets secondaires aigus d'une chimiothérapie ou d'un diagnostic immunosuppresseurs ou cancerostatiques, notamment à l'aide de carboxamides de pyridine substitués. Les composés de cette invention, représentés par le formule (I), ainsi que des associations médicamenteuses renfermant plusieurs composés contenant la vitamine B3 et/ou présentant une activité anti-pellagre, et des agents chimiothérapeutiques, sont particulièrement utiles pour les chimiothérapies et indications susmentionnées.
