Zusammenfassung:	Provided is a liquid preparation for contact lenses which contains a compound having a cyclic or tubular molecular structure such as cyclodextrin together with a drug component in a liquid vehicle and yet can advantageously exert the drug effect of the drug component. To a liquid vehicle containing a compound (A) having a cyclic or tubular molecular structure together with a definite drug component, a compound (B), which has a chain-type molecular structure and can be clathrated within the compound (A) as described above, is further added so that the compound (B) can be clathrated competitively with the drug component within the cyclic or tubular pores of the compound (A). Thus, the drug effect of the drug component can be advantageously controlled. La présente invention concerne une préparation liquide pour lentilles de contact qui contient un composé présentant une structure moléculaire cyclique ou tubulaire, telle de la cyclodextrine, ainsi qu'un composant médicamenteux dans un excipient liquide et qui peut avantageusement transmettre l'effet médicamenteux du composant médicamenteux. De plus, à un excipient liquide, contenant un composé (A) présentant une structure moléculaire cyclique ou tubulaire ainsi qu'un composant médicamenteux déterminé, est ajouté un composé (B) présentant une structure moléculaire en chaîne et pouvant être clathraté à l'intérieur du composé (A) de la manière précédemment décrite, de sorte que le composé (B) peut être simultanément clathraté avec le composant médicamenteux dans les pores cycliques ou tubulaires du composé (A). De ce fait, l'effet médicamenteux du composant médicamenteux peut avantageusement être régulé.
