The dispensing device and pharmaceutical composition of claim 1, wherein a dimension of the groove, further deepening the internal bottom of the well, does not affect an external bottom of the well, as the dimension is within a wall thickness of the bottom of the well. 3. The dispensing device and pharmaceutical composition of claim 1, wherein the pharmaceutical composition contains not more than 1% of total impurities when stored for up to 12 months. 4. The dispensing device and pharmaceutical composition of claim 1, wherein the dispensing device dispenses about 100 μl of the pharmaceutical composition per actuation, wherein a single actuation dispenses about 665 mcg of olopatadine and about 25 mcg or about 50 mcg of mometasone. 5. The dispensing device and pharmaceutical composition of claim 1, wherein the dispenser head is defined exteriorly by at least an end wall and a lateral wall, the end wall including the dispensing orifice; the dispensing device further including a cap releasably attachable to the dispenser head for covering at least the dispensing orifice, the cap including a sealing sleeve, extending from an interior surface of the cap, that communicates in a seal tight manner with a perimeter of the lateral wall of the dispenser head. 6. The dispensing device and pharmaceutical composition of claim 5, wherein an inner diameter of a distal end of the sealing sleeve is smaller than an exterior diameter of the lateral wall of the dispenser head, at a point of communication of the sealing sleeve with the lateral wall, to create the seal tight manner when the cap is in a closed position, whereby the distal end of the sealing sleeve is radially deformed. 7. The dispensing device and pharmaceutical composition of claim 1, wherein the pharmaceutical composition is configured to be delivered from the dispensing device to a patient suffering from allergic rhinitis to provide relief from symptoms of allergic rhinitis. 8. The dispensing device and pharmaceutical composition of claim 1, wherein the pharmaceutical composition comprises about 0.025% w/w mometasone furoate, about 0.665% w/w olopatadine hydrochloride, about 0.5% w/w carboxymethyl cellulose sodium, about 1.2% w/w mixture of microcrystalline cellulose and carboxymethyl cellulose sodium, about 0.02% w/w benzalkonium chloride, about 0.4% w/w sodium chloride, about 0.01% w/w di-sodium edetate, about 0.94% w/w sodium phosphate heptahydrate, and about 0.01% w/w polysorbate 80. 9. A dispensing device and pharmaceutical composition for nasal administration to a human, comprising: a container having a conically shaped internal bottom, wherein the internal bottom is angled downwardly from a side of the container toward a center, the center located along a longitudinal axis of the container, the internal bottom including a further angularly deepened well centrally located about the longitudinal axis, wherein the well of the internal bottom of the container further includes a groove therein, the groove further deepening an internal bottom of the well in a dimension greater than a wall thickness of the bottom of the well, thereby requiring modification of an external bottom of at least the well, wherein a support bead, with the groove therein, extends from at least an external bottom of the well, the support bead also extending across the longitudinal axis of the container; a dispenser head for dispensing the pharmaceutical composition from the container, the dispenser head comprising at least a pump, a dispensing channel, and a dispensing orifice; a dip tube extending along the longitudinal axis of the container, the dip tube having a proximal end communicating with the dispenser head and an open distal end extending into the well; wherein the open distal end of the dip tube extends into the groove or is located at a top of the groove; and a pharmaceutical composition in the container, the pharmaceutical composition comprising: about 0.001% w/w to about 0.075% w/w mometasone, an ester thereof, or a salt thereof in particulate form; about 0.5% w/w to about 0.8% w/w olopatadine or its salt in dissolved form; and a hydrocolloid in an amount sufficient to inhibit phase separation for at least 24 hours when stored at 25±2° C. and 60%±5% relative humidity. 10. A dispensing device and pharmaceutical composition for administration to a human, comprising: a container having a conically shaped internal bottom, the internal bottom being angled downwardly from a side of the container toward a center, the center located along a longitudinal axis of the container, the internal bottom including a further angularly deepened well centrally located about the longitudinal axis, the well including a groove therein, the groove further deepening an internal bottom of the well, the groove extending across the longitudinal axis of the container, whereby the internal bottom of the well, at the center, is a low point of the internal bottom of the container; a dispenser head for dispensing the pharmaceutical composition from the container, the dispenser head comprising at least a pump, a dispensing channel, and a dispensing orifice, the dispenser head defined exteriorly by at least an end wall and a lateral wall, the end wall including the dispensing orifice; a cap releasably attachable to the dispenser head for covering at least the dispensing orifice, the cap including a sealing sleeve, extending from an interior surface of the cap, that communicates in a seal tight manner with a perimeter of the lateral wall of the dispenser head; a dip tube extending along the longitudinal axis of the container, the dip tube having a proximal end communicating with the dispenser head and an open distal end extending into the well; wherein the open distal end of the dip tube extends into the groove or is located at a top of the groove; and a pharmaceutical composition of single phase suspension in the container, the pharmaceutical composition comprising: about 0.001% w/w to about 0.075% w/w mometasone, an ester thereof, or a salt thereof in particulate form; about 0.5% w/w to about 0.8% w/w olopatadine or its salt in dissolved form; and a hydrocolloid system in an amount sufficient to inhibit phase separation for at least 24 hours when stored at 25±2° C. and 60%±5% relative humidity. 11. The dispensing device and pharmaceutical composition of claim 10, wherein the sealing sleeve extends from a top inside wall of the cap. 12. The dispensing device and pharmaceutical composition of claim 11, wherein an inner diameter of a distal end of the sealing sleeve is smaller than an exterior diameter of the lateral wall of the dispenser head, at a point of communication of the sealing sleeve with the lateral wall, to create the seal tight manner when the cap is in a closed position, whereby the distal end of the sealing sleeve is radially deformed. 13. The dispensing device and pharmaceutical composition of claim 11, wherein the sealing sleeve has a wall thickness that decreases as the sealing sleeve extends away from the top inside wall of the cap. 14. The dispensing device and pharmaceutical composition of claim 10, wherein the cap includes, on an interior thereof, one or more protruding tabs that snap fit against the lateral wall of the dispenser head to hold the cap securely on the dispenser head in a closed position. 15.
