Answer: (A)
Wool Fat (Anhydrous Lanolin) is classified as an absorption base. It possesses lipophilic characteristics but contains sterols (cholesterol and isocholesterol) that allow it to absorb up to 200% to 300% of its own weight of water, forming stable water-in-oil (W/O) emulsions. In contrast, soft paraffin is an oleaginous hydrocarbon base.

A) Pastes melt rapidly at body temperature to release active ingredients into systemic circulation
B) Pastes contain a high proportion of dispersed insoluble solids (often 20% to 50%) making them stiffer and less greasy
C) Pastes are formulated exclusively with water-soluble polyethylene glycol bases
D) Pastes undergo syneresis when stored at refrigerated temperatures

Answer: (B)
Pastes are semisolid dermatological preparations that contain a large proportion (typically 20% to 50% w/w) of finely powdered insoluble solids (such as zinc oxide, starch, or calcium carbonate) suspended uniformly in a fatty or aqueous vehicle. This high solid fraction confers significant stiffness, porosity, and localized protective action compared to softer, greasier ointments.

Answer: (D)
Theobroma oil exhibits marked polymorphism with four crystalline states: gamma (mp ~18°C), alpha (mp ~22°C), beta-prime (mp ~28°C), and the stable beta form (mp ~34.5°C). Overheating cocoa butter above 36°C destroys all stable beta crystal nuclei; subsequent rapid chilling results in unstable gamma or alpha polymorphs that melt below normal room temperature and fail to solidify properly in molds.

A) 1.70 g
B) 1.60 g
C) 1.85 g
D) 1.94 g
Answer: (D)
Displacement value (DV) is the number of parts by weight of medicament that displaces 1 part by weight of the base: DV = W / (M - G + W), or amount of base displaced = Drug dose / DV. Here, 0.3 g / 5.0 = 0.06 g of cocoa butter displaced per suppository. Weight of cocoa butter needed per suppository = 2.0 g - 0.06 g = 1.94 g.

Answer: (B)
Polyethylene glycols (PEGs or Macrogols), also known as Carbowax bases, are synthetic water-soluble polymers blended (e.g., PEG 1000, 4000, and 6000) to achieve desired melting and dissolution profiles. Unlike theobroma oil, PEG suppository bases do not melt at 37°C; rather, they dissolve slowly in mucosal fluids, providing sustained drug release and resisting deformation in tropical climates.
