What is claimed is: 1. A topical pharmaceutical composition having enhanced penetration through the skin, the composition being in gel emulsion form and comprising:(a) an aqueous carrier; a safe and effective amount of a pharmaceutical active selected from the group consisting of anti-acne drugs, non-steroidal anti-inflammatory drugs, steroidal anti-inflammatory drugs, sunless tanning agents, wound healing agents, skin bleaching or lightening agents, antihistaminic drugs, antitussive drugs, antipruritic drugs, anticholinergic drugs, anti-emetic and antinauseant drugs, anorexic drugs, central stimulant drugs, antiarrhythmic drugs, β-adrenergic blocker drugs, cardiotonic drugs, antihypertensive drugs, diuretic drugs, vasodilator drugs, vasoconstrictor drugs, anti-ulcer drugs, anesthetic drugs, antidepressant drugs, tranquilizer and sedative drugs, antipsychotic drugs, antimicrobial drugs, antineoplastic drugs, antimalarial drugs, muscle relaxant drugs, antispasmodic drugs, antidiarrheal drugs, bone-active drugs, and mixtures thereof; and (c) from about 0.05% to about 5% of a non-ionic crosslinked polyacrylamide having a molecular weight of from about 1,000,000 to about 30,000,000, the polyacrylamide being predispersed in a water-immiscible oil containing a surfactant having an HLB of from about 7 to about 10. 2. The composition of claim 1 wherein said pharmaceutical active is a skin bleaching or lightening agent.
Drug Active The compositions of the present invention comprise a safe and effective amount of a drug active. The phrase "safe and effective amount", as used herein, means an amount of a drug high enough to significantly positively modify the condition to be treated, but low enough to avoid serious side effects (at a reasonable benefit/risk ratio), within the scope of sound medical judgement. A safe and effective amount of the drug will vary with the specific drug, the ability of the composition to penetrate the drug through the skin, the amount of composition to be applied, the particular condition being treated, the age and physical condition of the patient being treated, the severity of the condition, the duration of the treatment, the nature of concurrent therapy, and like factors.
